While the effects of exotic (non-native) pests on trees received broad attention and were extensively studied, fewer studies addressed the ecosystem-level consequences of these effects. Related studies so far mostly only targeted a very few dominant pests (e.g., hemlock woolly adelgid—HWA, beech bark disease—BBD, and spongy moth—SM) and were limited to aspects of the complex situation such as (1) pests’ direct physical disturbance to forest ecosystems, (2) altered geochemical elements of soils, water, and air (e.g., excretion), and (3) feedback effects from the alteration of ecosystems on plants, native insects, and present and future pest invasions. New studies also show that, in general, planted forests appear to be more prone to exotic pest invasions and thus suffer greater impacts than natural forests. Integrated studies are critically needed in the future to address (1) direct/indirect interactions of pests with ecosystem elements, (2) both short- and long-term effects, and (3) feedback effects. We discuss the implications of the new findings and corresponding management strategies.}, journal={Forests}, author={Guo, Qinfeng and Potter, Kevin M. and Ren, Hai and Zhang, Peixia}, year={2023}, month={Mar} }

Yet much less is known about the relationships between forest structural diversity (i.e., the number and physical arrangement of vegetation elements in a forest) and carbon cycling, and the factors that mediate these relationships. We capitalize on spaceborne lidar data from NASA's Global Ecosystem Dynamics Investigation (GEDI) and on-the-ground forest inventory and analysis (FIA) data from 1796 plots across the contiguous United States to assess relationships among the structural and species diversity of live trees and aboveground carbon storage. We found that carbon storage was more strongly correlated with structural diversity than with species diversity, for both forest inventory-based metrics of structural diversity (e.g., height and DBH diversity) and GEDI-based canopy metrics (i.e., foliage height diversity (FHD)). However, the strength of diversity‑carbon storage relationships was mediated by forest origin and forest types. For both plot-based and GEDI-based metrics, the relationship between structural diversity (i.e., height diversity, DBH diversity, and FHD) and carbon storage was positive in natural forests for all forest types (broadleaf, mixed, conifer). For planted forests, structural diversity showed positive relationships in planted conifer forests but not in planted mixed forests. Species diversity did not show strong associations with carbon storage in natural forests but showed a positive relationship in mixed coniferous-broadleaf planted forests. Although plot-based structural diversity metrics refine our understanding of drivers of forest carbon balances at the plot scale, remotely sensed metrics such as those from GEDI can help extend that understanding to regional/national scales in a spatially continuous manner. Carbon storage showed stronger associations with plot-based structural diversity than with stand age, soil variables, or climate variables. Incorporating structural diversity into management and restoration strategies could help guide efforts to increase carbon storage and mitigate climate change as nature-based solutions.}, journal={REMOTE SENSING OF ENVIRONMENT}, author={Crockett, Erin T.

The fundamental importance of genetic variation is recognized by its inclusion in the Montréal Process sustainability criteria and indicators for temperate and boreal forests. The indicator that focuses on forest species at risk of losing genetic variation, however, has been difficult to address in a systematic fashion. We combined two broad-scale datasets to inform this indicator for the United States: (1) tree species occurrence data from the national Forest Inventory and Analysis (FIA) plot network and (2) climatically and edaphically defined provisional seed zones, which are proxies for among-population adaptive variation. Specifically, we calculated the estimated proportion of small trees (seedlings and saplings) relative to all trees for each species and within seed zone sub-populations, with the assumption that insufficient regeneration could lead to the loss of genetic variation. The threshold between sustainable and unsustainable proportions of small trees reflected the expectation of age–class balance at the landscape scale. We found that 46 of 280 U.S. forest tree species (16.4%) may be at risk of losing genetic variation. California and the Southeast encompassed the most at-risk species. Additionally, 39 species were potentially at risk within at least half of the seed zones in which they occurred. Seed zones in California and the Southwest had the highest proportions of tree species that may be at risk. The results could help focus conservation and management activities to prevent the loss of adaptive genetic variation within tree species.}, number={1}, journal={FORESTS}, author={Potter, Kevin M. and Riitters, Kurt}, year={2022}, month={Jan} }

To quantify the degree of invasion by non-native trees in the United States, we combined two broad-scale datasets: (1) tree species occurrence data from the national Forest Inventory and Analysis (FIA) plot network and (2) ecoregions characterized by relatively homogeneous environmental conditions. Using the FIA statistical design, we created an indicator of non-native tree regeneration success by estimating the proportion of small trees (seedlings and saplings) relative to all trees for non-native species in the conterminous United States and southeast Alaska, Hawaii, and Puerto Rico. Species with at least 75 percent of their stems consisting of smaller stems were classified as highly invasive while those with 60 percent to 75 percent of smaller stems were classified as moderately invasive. Above these thresholds, non-native species are of ecological concern because they are established and reproducing successfully and therefore likely to continue to spread in the future. For the conterminous United States and southeast Alaska, we identified 16 highly invasive and four moderately invasive non-native tree species. Widespread highly invasive and relatively well-established species included Ailanthus altissima, Triadica sebifera, and Ulmus pumila. The richness of highly invasive species was the highest in parts of the Midwest and Mid-Atlantic States, followed by much of the Southeast. In Hawaii, we identified seven highly invasive and three moderately invasive non-native tree species. The most widespread highly invasive and well-established tree species in the archipelago were Psidium cattleyanum, Psidium guajava, Ardisia elliptica, and Syzygium cumini. The largest numbers of highly invasive species were inventoried in the lowland/leeward dry and mesic forests of O’ahu and the lowland wet and mesic forests of Hawai’i Island. Puerto Rico had 17 highly invasive and two moderately invasive tree species. The most widespread and well-established non-native species were Leucaena leucocephala, Spathodea campanulata, Coffea arabica, Syzygium jambos, and Melicoccus bijugatus. The results of this assessment offer insights into which species are most likely to alter forest ecosystems and which forests may be effectively managed to control invasive trees.}, journal={FRONTIERS IN FORESTS AND GLOBAL CHANGE}, author={Potter, Kevin M. and Riitters, Kurt H. and Guo, Qinfeng}, year={2022}, month={Aug} }

We assess the abundance, geographic distribution, contribution to forest structure (including carbon), and temporal trends of nonnative tree species between the most current inventory and the previous one, ranging from 3 to 15 years earlier, within the conterminous United States (CONUS) and U.S.-affiliated islands in the Caribbean and the Pacific. We used publicly available data from the U.S. Department of Agriculture Forest Service, Forest Inventory and Analysis (FIA) program. Our analysis is by ecological section (ecosection) within ecological provinces of the CONUS and islandwide for Pacific and Caribbean islands. We found that the forest land area with nonnative tree species in the CONUS is 18.8 million acres (7.6 million ha) and is expanding at about 500,000 acres (202 343 ha) per year. The contribution of nonnative tree species in the CONUS to the structural component of forests (basal area and tree density) increased slightly. The mean live aboveground tree carbon of nonnative tree species ranged from 0.39 ton per acre (0.88 Mg/ha) for saplings (small trees with diameter at breast height [dbh] ≥1–<5 inches [≥2.54–<12.7 cm]) to 2.47 tons per acre (5.54 Mg/ha) for all trees (≥1 inch dbh), saplings included. These numbers are equivalent to 19 and 10 percent of the total carbon storage for their respective size classes in the forest plots where they occur, and they slowly increased between previous and current inventories. The contribution of nonnative tree species to the carbon storage of CONUS forests is 92.6 gigapounds (42 Tg) of C or about 0.05 percent of the amount stored in those forests. Nonnative tree species also sequester 1.3 gigapounds (0.6 Tg) of C annually or about 0.5 percent of the carbon sink of CONUS forests. The type and intensity of human activity is generally associated with the presence of nonnative tree species. A similar relationship is at play in Caribbean and Pacific islands and in the mainland forests of the CONUS. Additionally, a greater concentration of human activities in islands makes the nonnative tree species more common there than in the CONUS.}, institution={U.S. Department of Agriculture, Forest Service, International Institute of Tropical Forestry}, author={Lugo, Ariel E. and Smith, James E. and Potter, Kevin M. and Vega, Humfredo Marcano and Kurtz, Cassandra M.}, year={2022}, month={Jan} }

Currently, both exotic and native insects and diseases are producing extensive ecological damage and economic impacts. As part of an effort to identify United States tree species and forests most vulnerable to these epidemics, we compiled a list of the most serious insect and disease threats for 419 native tree species and assigned a severity rating for each of the 1378 combinations between mature tree hosts and 339 distinct insect and disease agents. We then joined this list with data from a spatially unbiased and nationally consistent forest inventory to assess the potential ecological impacts of insect and disease infestations. Specifically, potential host species mortality for each host/agent combination was used to weight species importance values on approximately 132,000 Forest Inventory and Analysis (FIA) plots across the conterminous 48 United States. When summed on each plot, these weighted importance values represent an estimate of the proportion of the plot’s existing importance value at risk of being lost. These plot estimates were then used to identify statistically significant geographic hotspots and coldspots and of potential forest impacts associated with insects and diseases in total, and for different agent types. In general, the potential impacts of insects and diseases were greater in the West, where there are both fewer agents and less diverse forests. The impact of non-native invasive agents, however, was potentially greater in the East. Indeed, the impacts of current exotic pests could be greatly magnified across much of the Eastern United States if these agents are able to reach the entirety of their hosts’ ranges. Both the list of agent/host severities and the spatially explicit results can inform species-level vulnerability assessments and broad-scale forest sustainability reporting efforts, and should provide valuable information for decision-makers who need to determine which tree species and locations to target for monitoring efforts and pro-active management activities.}, number={4}, journal={Forests}, publisher={MDPI AG}, author={Potter, Kevin and Escanferla, Maria and Jetton, Robert and Man, Gary}, year={2019}, month={Apr}, pages={304} }

Scientists and managers from throughout the United States Forest Service developed a conservation priority-setting framework for forest tree species at risk from insects and disease and other threats. The Project CAPTURE (Conservation Assessment and Prioritization of Forest Trees Under Risk of Extirpation) framework is data-driven and guided by expert opinion, allowing the quantitative grouping of species into vulnerability classes that may require different management and conservation strategies. We applied this framework to categorize and prioritize 419 native North American tree species for conservation, monitoring, and management using trait data and insect and disease threat data for each host tree species. The categorization is based on vulnerability factors relating to each tree species’ (1) insect and disease threat severity, (2) sensitivity to insect and disease infestation, and (3) capacity to adapt to insect and disease infestation. We used K-means clustering to group species into 11 classes based on these vulnerability dimensions. The three most vulnerable classes encompassed 15 species which require the most immediate conservation intervention. Two additional classes face less severe insect and disease threats and may be good candidates for resistance breeding efforts. Other groups had traits associated with high sensitivity and/or low adaptive capacity to potential future insect and disease threats, suggesting that these species need close monitoring. This assessment tool should be valuable for decision-makers determining which species and populations to target for monitoring efforts and for pro-active gene conservation and management activities.}, journal={Global Ecology and Conservation}, publisher={Elsevier BV}, author={Potter, Kevin M. and Escanferla, Maria E. and Jetton, Robert M. and Man, Gary and Crane, Barbara S.}, year={2019}, month={Apr}, pages={e00622} }

High species diversity in host communities may promote pest invasions by providing more niches (i.e., facilitation), but it can also diminish invasion success because low host dominance may make it more difficult for pests to establish (i.e., dilution). Most studies to date have focused on small-scale, experimental, or individual pest/disease species, while large-scale empirical studies, especially in natural ecosystems, are extremely rare. Using subcontinental-level data, we examined the role of tree diversity on pest invasion across the conterminous United States and found that the tree-pest diversity relationships are hump-shaped. Pest diversity increases with tree diversity at low tree diversity (because of facilitation or amplification) and is reduced at higher tree diversity (as a result of dilution). Thus, tree diversity likely regulates forest pest invasion through both facilitation and dilution that operate simultaneously, but their relative strengths vary with overall diversity. Our findings suggest the role of native species diversity in regulating nonnative pest invasions.}, number={15}, journal={Proceedings of the National Academy of Sciences}, publisher={Proceedings of the National Academy of Sciences}, author={Guo, Qinfeng and Fei, Songlin and Potter, Kevin M. and Liebhold, Andrew M. and Wen, Jun}, year={2019}, month={Mar}, pages={7382–7386} }

However, how habitat fragmentation per se may affect forest insect and disease invasion has not been well studied, especially the related patterns over regional or subcontinental scales. Here, using national survey data on forest pest richness and fragmentation data across United States forest ecosystems, we examine how forest fragmentation and edge types (neighboring land cover) may affect pest richness at the county level. Our results show that habitat fragmentation and edge types both affected pest richness. In general, specialist insects and pathogens were more sensitive to fragmentation and edge types than generalists, while pathogens were much less sensitive to fragmentation and edge types than insect pests. Most importantly, the developed land edge type contributed the most to the richness of nonnative insects and diseases, whether measured by the combination of all pest species or by separate guilds or species groups (i.e., generalists vs. specialists, insects vs. pathogens). This observation may largely reflect anthropogenic effects, including propagule pressure associated with human activities.

This paper describes a species prioritization approach that incorporates both the rarity of species, because of the increased vulnerability associated with rare species, and their evolutionary distinctiveness (ED), a measure of evolutionary originality. Rarity and ED scores, and scores for the two combined, were calculated for 352 North American forest tree species. A weak but significant phylogenetic signal was associated with species rarity. The scores were used to weight species importance values on approximately 130,000 forest inventory plots across the conterminous United States. The resulting plot-level estimates of conservation value were employed to identify geographic hotspots of forests with high conservation value, and to assess whether forests with protected status effectively conserve rarity and ED. Rarity hotspots were detected in California, the Southwest, central Texas, and Florida. Hotspots of ED included locations along the Pacific Coast, in the Northern Rockies, and in scattered eastern locations. Protected forest areas across the United States effectively conserve ED, but not rarity. In fact, rarity was lowest in areas with the highest protection, and highest in areas with no or unknown protected status. Multiple-use protected areas had higher ED, but not rarity, than restricted-use protected areas. Protected area effectiveness varied across the country. Such spatially explicit assessment approaches can help determine which forests to target for monitoring efforts and pro-active management activities.}, journal={Biological Conservation}, publisher={Elsevier BV}, author={Potter, Kevin M.}, year={2018}, month={Aug}, pages={34–46} }

The effective size of this resistance, however, varies geographically. Here we investigate the drivers of this heterogeneity in the context of known contributions of native trees to the resistance of forests in the eastern United States of America to plant invasions. Using 42,626 spatially referenced forest community observations, we quantified spatial heterogeneity in relationships between evolutionary relatedness amongst native trees and both invasive plant species richness and cover. We then modelled the variability amongst the 91 ecological sections of our study area in the slopes of these relationships in response to three factors known to affect invasion and evolutionary relationships –environmental harshness (as estimated via tree height), relative tree density and environmental variability. Invasive species richness and cover declined in plots having less evolutionarily related native trees. The degree to which they did, however, varied considerably amongst ecological sections. This variability was explained by an ecological section’s mean maximum tree height and, to a lesser degree, SD in maximum tree height (R2GLMM = 0.47 to 0.63). In general, less evolutionarily related native tree communities better resisted overall plant invasions in less harsh forests and in forests where the degree of harshness was more homogenous. These findings can guide future investigations aimed at identifying the mechanisms by which evolutionary relatedness of native species affects exotic species invasions and the environmental conditions under which these effects are most pronounced.}, journal={NeoBiota}, publisher={Pensoft Publishers}, author={Iannone III, Basil V. and Potter, Kevin M. and Guo, Qinfeng and Jo, Insu and Oswalt, Christopher M. and Fei, Songlin}, year={2018}, month={Dec}, pages={87–105} }

Background and Objectives: Protected areas are a fundamental component of natural resource conservation. The exposure of protected forests to invasive plants can impede achievement of conservation goals, and the effectiveness of protection for limiting forest invasions is uncertain. We conducted a macroscale assessment of the exposure of protected and unprotected forests to harmful invasive plants in the eastern United States. Materials and Methods: Invasibility (the probability that a forest site has been invaded) was estimated for 82,506 inventory plots from site and landscape attributes. The invaded forest area was estimated by using the inventory sample design to scale up plot invasibility estimates to all forest area. We compared the invasibility and the invaded forest area of seven categories of protection with that of de facto protected (publicly owned) forest and unprotected forest in 13 ecological provinces. Results: We estimate approximately 51% of the total forest area has been exposed to harmful invasive plants, including 30% of the protected forest, 38% of the de facto protected forest, and 56% of the unprotected forest. Based on cumulative invasibility, the relative exposure of protection categories depended on the assumed invasibility threshold. Based on the invaded forest area, the five least-exposed protection categories were wilderness area (13% invaded), national park (18%), sustainable use (26%), nature reserve (31%), and de facto protected Federal land (36%). Of the total uninvaded forest area, only 15% was protected and 14% had de facto protection. Conclusions: Any protection is better than none, and public ownership alone is as effective as some types of formal protection. Since most of the remaining uninvaded forest area is unprotected, landscape-level management strategies will provide the most opportunities to conserve it.}, number={11}, journal={Forests}, publisher={MDPI AG}, author={Riitters, Kurt and Potter, Kevin and Iannone, Basil, III and Oswalt, Christopher and Guo, Qinfeng and Fei, Songlin}, year={2018}, month={Nov}, pages={723} }

Unique responses to climate change can occur across intraspecific levels, resulting in individualistic adaptation or movement patterns among populations within a given species. Thus, the need to model potential responses among genetically distinct populations within a species is increasingly recognized. However, predictive models of future distributions are regularly fit at the species level, often because intraspecific variation is unknown or is identified only within limited sample locations. In this study, we considered the role of intraspecific variation to shape the geographic distribution of ponderosa pine (Pinus ponderosa), an ecologically and economically important tree species in North America. Morphological and genetic variation across the distribution of ponderosa pine suggest the need to model intraspecific populations: the two varieties (var. ponderosa and var. scopulorum) and several haplotype groups within each variety have been shown to occupy unique climatic niches, suggesting populations have distinct evolutionary lineages adapted to different environmental conditions. We utilized a recently available, geographically widespread dataset of intraspecific variation (haplotypes) for ponderosa pine and a recently devised lineage distance modeling approach to derive additional, likely intraspecific occurrence locations. We confirmed the relative uniqueness of each haplotype‐climate relationship using a niche‐overlap analysis, and developed ecological niche models (ENMs) to project the distribution for two varieties and eight haplotypes under future climate forecasts. Future projections of haplotype niche distributions generally revealed greater potential range loss than predicted for the varieties. This difference may reflect intraspecific responses of distinct evolutionary lineages. However, directional trends are generally consistent across intraspecific levels, and include a loss of distributional area and an upward shift in elevation. Our results demonstrate the utility in modeling intraspecific response to changing climate and they inform management and conservation strategies, by identifying haplotypes and geographic areas that may be most at risk, or most secure, under projected climate change.}, number={6}, journal={Systematic Biology}, publisher={Oxford University Press (OUP)}, author={Maguire, Kaitlin C and Shinneman, Douglas J and Potter, Kevin M and Hipkins, Valerie D}, editor={Matzke, NicholasEditor}, year={2018}, month={Mar}, pages={965–978} }

A recent study using mitochondrial DNA analysis demonstrated substantial genetic variation among ponderosa pine populations in the western U.S., identifying 10 haplotypes with unique evolutionary lineages that generally correspond spatially with distributions of the Pacific (P. p. var. ponderosa) and Rocky Mountain (P. p. var. scopulorum) varieties. To elucidate the role of climate in shaping the phylogeographic history of ponderosa pine, we used nonparametric multiplicative regression to develop predictive climate niche models for two varieties and 10 haplotypes and to hindcast potential distribution of the varieties during the last glacial maximum (LGM), ~22,000 yr BP. Our climate niche models performed well for the varieties, but haplotype models were constrained in some cases by small datasets and unmeasured microclimate influences. The models suggest strong relationships between genetic lineages and climate. Particularly evident was the role of seasonal precipitation balance in most models, with winter- and summer-dominated precipitation regimes strongly associated with P. p. vars. ponderosa and scopulorum, respectively. Indeed, where present-day climate niches overlap between the varieties, introgression of two haplotypes also occurs along a steep clinal divide in western Montana. Reconstructed climate niches for the LGM suggest potentially suitable climate existed for the Pacific variety in the California Floristic province, the Great Basin, and Arizona highlands, while suitable climate for the Rocky Mountain variety may have existed across the southwestern interior highlands. These findings underscore potentially unique phylogeographic origins of modern ponderosa pine evolutionary lineages, including potential adaptations to Pleistocene climates associated with discrete temporary glacial refugia. Our predictive climate niche models may inform strategies for further genetic research (e.g., sampling design) and conservation that promotes haplotype compatibility with projected changes in future climate.}, number={3}, journal={PLOS ONE}, publisher={Public Library of Science (PLoS)}, author={Shinneman, Douglas J. and Means, Robert E. and Potter, Kevin M. and Hipkins, Valerie D.}, editor={Chiang, Tzen-YuhEditor}, year={2016}, month={Mar}, pages={e0151811} }

Empirical studies and meta‐analyses of invasibility have produced inconsistent and even conflicting results. This lack of consistency, and subsequent difficulty in making broad cross‐habitat comparisons, stem in part from (1) the indiscriminant use of a closely related, but fundamentally different concept, that of degree of invasion (DI) or level of invasion; and (2) the lack of common invasibility metrics, as illustrated by our review of all invasibility‐related papers published in 2013. To facilitate both cross‐habitat comparison and more robust ecological generalizations, we clarify the definitions of invasibility and DI, and for the first time propose a common metric for quantifying invasibility based on a habitat's resource availability as inferred from relative resident species richness and biomass. We demonstrate the feasibility of our metric using empirical data collected from 2475 plots from three forest ecosystems in the eastern United States. We also propose a similar metric for DI. Our unified, resource‐based metrics are scaled from 0 to 1, facilitating cross‐habitat comparisons. Our proposed metrics clearly distinguish invasibility and DI from each other, which will help to (1) advance invasion ecology by allowing more robust testing of generalizations and (2) facilitate more effective invasive species control and management.}, number={10}, journal={Ecology}, publisher={Wiley-Blackwell}, author={Guo, Qinfeng and Fei, Songlin and Dukes, Jeffrey S. and Oswalt, Christopher M. and Iannone, Basil V., III and Potter, Kevin M.}, year={2015}, month={Oct}, pages={2613–2621} }

To assess this need, we used empirical data from a national‐level survey of forest in the contiguous 48 states of the USA to identify geographic hotspots of forest plant invasion for three distinct invasion characteristics: invasive species richness, trait richness (defined as the number of the five following plant growth forms represented by the invasive plants present at a given location: forbs, grasses, shrubs, trees, and vines), and species richness within each growth form. Three key findings emerged. 1) The hotspots identified encompassed from 9 to 23% of the total area of our study region, thereby revealing many forests to be not only invaded, but highly invaded. 2) Substantial spatial disagreement among hotspots of invasive species richness, invasive trait richness, and species richness of invasive plants within each growth form revealed many locations to be hotspots for invader traits, or for particular growth forms of invasive plants, rather than for invasive plants in general. 3) Despite eastern forests exhibiting higher levels of plant invasion than western forests, species richness for invasive forbs and grasses in the west were respectively greater than and equivalent to levels found in the east. Contrasting patterns between eastern and western forests in the number of invasive species detected for each growth form combined with the spatial disagreement found among hotspot types suggests trait‐based variability in invasion drivers.

It exhibits complicated patterns of morphological and genetic variation, suggesting that it may be in the process of differentiating into distinct regional lineages. A robust analysis of genetic variation across the ponderosa pine complex is necessary to ensure the effectiveness of management and conservation efforts given the species’ large distribution, the existence of many isolated disjunct populations, and the potential susceptibility of some populations to climate change and other threats. We used highly polymorphic nuclear microsatellite markers and isozyme markers from 3113 trees in 104 populations to assess genetic variation and structure across the geographic range of ponderosa pine. The results reveal pervasive inbreeding and patterns of genetic diversity consistent with the hypothesis that ponderosa existed in small, as-yet-undetected Pleistocene glacial refugia north of southern Arizona and New Mexico. The substructuring of genetic variation within the species complex was consistent with its division into two varieties, with genetic clusters within varieties generally associated with latitudinal zones. The analyses indicate widespread gene flow and/or recent common ancestry among genetic clusters within varieties, but not between varieties. Isolated disjunct populations had lower genetic variation by some measures and greater genetic differentiation than main-range populations. These results should be useful for decision-making and conservation planning related to this widespread and important species.}, number={3}, journal={Tree Genetics & Genomes}, publisher={Springer Nature}, author={Potter, Kevin M. and Hipkins, Valerie D. and Mahalovich, Mary F. and Means, Robert E.}, year={2015}, month={Apr} }

Relationships between species richness, evolutionary diversity, and aboveground live tree biomass across U.S. forests}, volume={321}, ISSN={0378-1127}, url={http://dx.doi.org/10.1016/j.foreco.2013.06.026}, DOI={10.1016/j.foreco.2013.06.026}, abstractNote={Biodiversity conveys numerous functional benefits to forested ecosystems, including community stability and resilience. In the context of managing forests for climate change mitigation/adaptation, maximizing and/or maintaining aboveground biomass will require understanding the interactions between tree biodiversity, site productivity, and the stocking of live trees. Species richness may not be the most appropriate tree biodiversity metric in this context as it weights all species as equally important. Measures that account for evolutionary relationships among species should be more biologically meaningful surrogates of functional diversity within forest communities, given that more phylogenetically distinct species should contribute more to the diversity of traits within a community. Using data from approximately 79,000 permanent and standardized forest inventory plots across the United States, we assessed trends in live aboveground tree biomass (LAGB) in relation to metrics of forest tree biodiversity at national and regional scales, controlling for site productivity and live tree stocking. These metrics included four measures of evolutionary diversity associated with distinct components of functional variation. In certain situations and locations across the U.S., evolutionary diversity metrics supply additional information about forest stands beyond that provided by simple species richness counts. This information can potentially include critical insight into tree functional attributes inherently related to evolutionary diversity. Relationships nationally between LAGB and most biodiversity metrics weakened with increasing site productivity and with increasing live tree stocking: The greater the site productivity and tree stocking, the less likely that higher biodiversity was associated with greater LAGB. This is consistent with the expectation that the coexistence of functionally different species increases forest productivity in less productive and more stressful environments, while dominant and highly productive species are able to competitively dominate in more productive habitats. Phylogenetic species clustering (PSC) was increasingly correlated with LAGB as live tree stocking increased on low-productivity sites, suggesting that the co-occurrence of tree species more widely distributed across the phylogenetic tree of life, and therefore likely possessing a wider variety of functional attributes, resulted in greater biomass accumulation on poorer sites. PSC and species richness appear to be the best biodiversity predictors for LAGB on the low-productivity sites likely to be most important for carbon/biomass management. These biodiversity metrics will be important for maximizing biomass/carbon for future carbon sequestration or bioenergy needs and should serve as indicators of forest function in forest resource assessments.}, journal={Forest Ecology and Management}, publisher={Elsevier BV}, author={Potter, Kevin M. and Woodall, Christopher W.}, year={2014}, month={Jun}, pages={117–129} }

Meanwhile, a pattern of phylogenetic evenness, in which the species are less closely related than by chance, may indicate competitive exclusion or interspecies facilitation. The ecological integrity of such communities may be less at risk because they may encompass a wider variety of evolutionary adaptations. Using a network of more than 100,000 forest inventory plots across the conterminous United States, we tested whether community phylogenetic structure was significantly clustered or even at multiple scales. Clustering predominated across most of the study area, indicating the widespread significance of evolutionary niche conservatism, except in areas of the west. Phylogenetic structure varied along environmental gradients, suggesting that clustering predominates in more favorable locations and evenness predominates in areas with harsher environments. These results have implications for broad-scale forest health monitoring.}, number={5}, journal={Forest Science}, publisher={Oxford University Press (OUP)}, author={Potter, Kevin M. and Koch, Frank H.}, year={2014}, month={Oct}, pages={851–861} }

Model The EBR model is a multiyear two-stage goal and spatial equilibrium program, and it was modified for this study to model the economic feasibility of salvage of dead timber on public and private lands in the West. Although details of the model, including its mathematical formulation, are provided in Prestemon et al. (2008, 2012), describing the modeling framework is important for understanding the current study. EBR can be run for a single year or multiple years, treating timberland (salvaging standing dead trees, in this study) each year according to a predefined set of objectives. After each simulated year, timber inventory data are updated, with the transition to the next year defined by stand growth, new mortality available for salvage, and the volumes removed in the previous year’s solution. The first stage of this revised version of the EBR model is a goal program that selects locations in the West to salvage timber by maximizing a goal-weighted sum of salvage volumes, subject to maximum and minimum harvest constraints, a feasible forest product market solution, and an assumed maximum amount of expenditures available to harvest and transport salvage timber to mills. The fundamental unit of information about timber volumes (salvage, nonsalvage) to which the goal weights are applied in the EBR model is the Forest Inventory and Analysis (FIA) plot. To allow for a reasonably fast solution, plot-level information is summed to a spatial and ownership aggregate. Plot-level information includes the average distance to the nearest five sawmills (which consume sawlogs) and the average distance to the two nearest pulp or pole mills (consuming the smaller diameter portions of trees in the stand). Other variables reported or calculated at the plot level include volumes by product category (merchantable live and dead sawlogs and pulpwood) and tree groups—ponderosa pine (Pinus ponderosa and P. lambertiana), lodgepole pine (P. contorta), southern pine (especially P. echinata, P. palustris, P. elliottii, P. taeda), other softwood, and hardwood; ownership (national forest, other public, private); LANDFIRE Map Zone (LANDFIRE 2010); the harvest cost for removing live or dead volumes; and, an administration cost of $200/acre for public and $100/acre for private timberland salvage. In this study, we aggregated plot-level information up to the map zone for each ownership group for each of the 12 western states in the contiguous United States. LANDFIRE map zones are generalized geographical units with similar ecological and biophysical characteristics. The 50 United States contain 79 such zones, which span state boundaries. The 12 states in this study contain 29 map zones, although the area and total standing timber volume found in these zones vary widely. Therefore, the basic modeling units, from which treatment volumes could be obtained in the first stage, are the map zone–ownership aggregates in each of the 12 western states. Depending on the simulation implemented (more information on the simulations is provided in the next section), treatment volumes selected in the first stage could be obtained from parts or all of one map zone–ownership aggregate. Harvest costs, timber volume information by species and live or dead status, and transport costs were expanded to the map zone–ownership aggregate using an area expansion factor. The result is a summary of the total area of stands of salvable timber in each map zone–ownership aggregate and for each of these the weighted average volumes per acre by species by product by live and salvable dead, weighted average transport distances to mills, and the weighted average harvest cost. Finally, the goal weights placed on map zone–ownership aggregates were the presolution net revenues of timber salvage removed; only dead standing salvable timber could be removed. The net revenue in the first stage is defined as the premarket solution value of salvaged sawlogs and pulpwood by species: the delivered volume multiplied by each product’s respective market price times a salvage discount factor minus the total stand’s harvest and transport costs per acre. As defined, net revenues can be negative. In effect, the EBR model had an ordered preference for salvage of timberlands according to their per acre net revenues. The second stage of the EBR model maximizes, subject to the salvage volumes selected in the first stage in each map zone–ownership aggregate location, the sum of timber product producer and consumer surplus minus transport costs for harvested volumes of both salvage and nonsalvage timber moving across state and international borders (Samuelson 1952, Takayama and Judge 1964). The basic timber product market modeling unit—two levels of aggregation higher than the map zone–ownership—in which equilibrium product prices by species group are obtained, is the state. Trade restrictions that ban exports of roundwood flowing from western US federal lands are imposed. State level maximum processed volumes are determined by state-level mill capacities that act as a physical limit on the volume of timber products that can be processed within the state without new processing capacity being added. We allow these capacities to be exceeded by up to 30% to reflect the possibility of adding shifts to existing mills (Prestemon et al. 2008). The EBR model also allows for the siting of new processing capacity, although this is not implemented endogenously (as in Ince et al. 2008). The second stage optimal solution is a set of market equilibrium product prices, and the volumes by species of timber salvaged (and harvested nonsalvage) produced in each state, consumed at mills in each location, and traded across state and international borders. The result of a set of a multiyear simulations run by the EBR model is an assessment of the net revenue impacts of salvage on national forests, other public, and private lands in the 12 contiguous western US states. In this study, we further summarize the results in terms of salvage costs and salvage revenues by state and ownership group. While not reported in this study, model outputs also include prices and economic welfare changes resulting from changes in salvage. Such changes may be of interest when seeking to quantify how salvage negatively impacts the welfare of owners of nonsalvage timber (e.g., Prestemon and Holmes 2004, Prestemon et al. 2006). It is worth noting, however, that the net revenues generated from salvage on private lands are gross, before taxes. By varying an assumption on the magnitude of a government program to salvage national forest, other public, or private timber, we describe how the geographical focus of a government-subsidized or national forest salvage program might shift across states in the West. By carrying out a “what-if” scenario that tests the effects of a doubling of the total mill capacity in two states of the West that have been heavily affected by the mountain pine beetle—Montana and Colorado—we examine how efforts to encourage or subsidize the consumption of salvaged timber would affect net revenues of salvage obtained by timberland owners (public and private). Finally, by altering our assumption about the regular accumulation of additional standing volumes of 144 WEST. J. APPL. FOR. 28(4) 2013 salvage timber—from a set annual percentage increase to no more accumulation of standing dead timber—we assess how the spatial targeting of salvage efforts on national forests and other lands would be affected. Data Timber inventory data from Forest Service FIA surveys were assembled for all timberland that is open to harvest and not protected by easements or otherwise set aside for conservation purposes in 12 western US states. The survey years used for each state are reported in Table 1. Data are summarized by owner group (all owners and national forests only), by species group (ponderosa pine, lodgepole pine, other softwood, and hardwood), and by product (sawtimber—representing the cubic foot volume in the sawlog portion of the tree—and pulpwood—representing all other growing stock volume in the tree). Trees coded as standing dead had only total volume measured, so allocations to sawtimber and pulpwood were assumed to be identical to the overall share of sawtimber and pulpwood found in the live trees on the plot, if any. Forested plots without live trees were assumed to have a sawtimber share of standing volume equal to 0.8. Further information on FIA methods can be found in Bechtold and Patterson (2005). While initial interest was in modeling salvage of only MPB-killed stands, the FIA data did not offer the option to restrict the volume and acreage data for dead timber based on the cause of mortality. While some information on MPB-affected forests in the West is available from aerial detection surveys, the data produced by these surveys (e.g., Backsen and Howell 2013) were not suitable for our study (see Meddens et al. 2012). Although modeling the salvage of timber killed by all causes is not the same as modeling the salvage of MPB-killed trees, salvage operations should be indifferent to the cause of mortality. One advantage of employing FIA data is that plots are measured on a representative sample frame and, therefore, have a level of accuracy that provides greater confidence in simulated salvage programs. FIA plots have representative samples of species, sizes of trees, and site conditions, which allow for accurate assessments of both the materials that can be removed during salvage and the costs of removal of salvable timber.

Tree species distributions may have to shift to match new environmental conditions, potentially requiring the establishment of some species entirely outside of their current distributions to thrive. Even within the portions of tree species ranges that remain generally suitable for the species, local populations may not be well-adapted to altered local conditions. To assist efforts to restore forests and to maximize forest productivity in the face of climate change, we developed a set of 30,000 quantitatively defined seed transfer “ecoregions” across the globe. Reflecting current and future conditions, these were created by combining global maps of potentially important environmental characteristics using a large-scale statistical clustering technique. This approach assigns every 4 km2 terrestrial raster cell into an ecoregion using non-hierarchical clustering of the cells in multivariate space based on 16 environmental variables. Two cells anywhere on the map with similar combinations of environmental characteristics are located near each other in this data space; cells are then classified into relatively homogeneous ecoregion clusters. Using two global circulation models and two emissions scenarios, we next mapped the predicted environmentally equivalent future locations of each ecoregion in 2050 and 2100. We further depicted areas of decreasing environmental similarity to given ecoregions, both in current time and under climate change. This approach could help minimize the risk that trees used for production, restoration, reforestation, and afforestation are maladapted to their planting sites.}, number={5-6}, journal={New Forests}, publisher={Springer Nature}, author={Potter, Kevin M. and Hargrove, William W.}, year={2012}, month={Apr}, pages={581–599} }

In the longer term, tree species may be unable to persist in some locations while they become established in new places. Over both time frames, forest tree biodiversity may change in unexpected ways. Using repeated inventory measurements five years apart from more than 7000 forested plots in the eastern United States, we tested three hypotheses: phylogenetic diversity is substantially different from species richness as a measure of biodiversity; forest communities have undergone recent changes in phylogenetic diversity that differ by size class, region, and seed dispersal strategy; and these patterns are consistent with expected early effects of climate change. Specifically, the magnitude of diversity change across broad regions should be greater among seedlings than in trees, should be associated with latitude and elevation, and should be greater among species with high dispersal capacity. Our analyses demonstrated that phylogenetic diversity and species richness are decoupled at small and medium scales and are imperfectly associated at large scales. This suggests that it is appropriate to apply indicators of biodiversity change based on phylogenetic diversity, which account for evolutionary relationships among species and may better represent community functional diversity. Our results also detected broadscale patterns of forest biodiversity change that are consistent with expected early effects of climate change. First, the statistically significant increase over time in seedling diversity in the South suggests that conditions there have become more favorable for the reproduction and dispersal of a wider variety of species, whereas the significant decrease in northern seedling diversity indicates that northern conditions have become less favorable. Second, we found weak correlations between seedling diversity change and latitude in both zones, with stronger relationships apparent in some ecoregions. Finally, we detected broadscale seedling diversity increases among species with longer‐distance dispersal capacity, even in the northern zone, where overall seedling diversity declined. The statistical power and geographic extent of such analyses will increase as data become available over larger areas and as plot measurements are repeated at regular intervals over a longer period of time.}, number={2}, journal={Ecological Applications}, publisher={Wiley}, author={Potter, Kevin M. and Woodall, Christopher W.}, year={2012}, month={Mar}, pages={517–531} }

To guide gene conservation strategies for this imperiled conifer, we conducted a range-wide genetic variation study for eastern hemlock, amplifying 13 highly polymorphic nuclear microsatellite loci in 1,180 trees across 60 populations. The results demonstrate that eastern hemlock exhibits moderate inbreeding, possibly a signature of a prehistoric decline associated with a widespread insect outbreak. Contrary to expectations, populations in formerly glaciated regions are not less genetically diverse than in the putative southern refugial region. As expected, peripheral disjunct populations are less genetically diverse than main-range populations, but some are highly genetically differentiated or contain unique alleles. Spatially explicit Bayesian clustering analyses suggest that three or four Pleistocene glacial refuges may have existed in the Southeastern United States, with a main post-glacial movement into the Northeast and the Great Lakes region. Efforts to conserve eastern hemlock genetic material should emphasize the capture of broad adaptability that occurs across the geographic range of the species, as well as genetic variability within regions with the highest allelic richness and heterozygosity, such as the Southern Appalachians and New England, and within disjunct populations that are genetically distinct.

The study also included 17 populations of Pinus patula and Pinus tecunumanii chosen for their resistance or susceptibility to the pitch canker fungus based on previous research. Seedlings from all 68 populations were screened for pitch canker resistance, and results were correlated to mean genetic diversity and collection site variables. Results indicate that P. oocarpa exhibits average to above‐average levels of genetic diversity (

Introgression between P. oocarpa and P. tecunumanii populations appears to be common. Pinus oocarpa populations showed high resistance to pitch canker (stemkill 3%–8%), a disease that the species has presumably coevolved with in Mesoamerica. Resistance was significantly correlated to the latitude, longitude, and altitude of the collection site but not to any genetic‐diversity parameters or degree of admixture with P. tecunumanii.}, number={5}, journal={International Journal of Plant Sciences}, publisher={University of Chicago Press}, author={Dvorak, W. S. and Potter, K. M. and Hipkins, V. D. and Hodge, G. R.}, year={2009}, month={Jun}, pages={609–626} }

An analysis of eight microsatellite markers isolated from Fraser fir found that the species was out of Hardy–Weinberg equilibrium, with a significant deficiency of heterozygosity and a high degree of inbreeding (FIS= 0.223) relative to other conifers, perhaps associated in part with the young life stage of the trees included in the analysis. The analysis detected a significant but small amount of genetic differentiation among Fraser fir populations (FST= 0.004) and revealed that the geographical and latitudinal distances between populations, but not population area, were significantly correlated with their pairwise genetic differences. Both gene flow and postglacial migration history may have influenced the genetic architecture of the species. The results will be useful in the genetic conservation of Fraser fir, a species experiencing severe mortality following infestation by an exotic insect.}, number={8}, journal={Canadian Journal of Forest Research}, publisher={Canadian Science Publishing}, author={Potter, Kevin M. and Frampton, John and Josserand, Sedley A. and Nelson, C.

Information about the genetic composition of eastern hemlock is necessary to guide ex situ conservation efforts in the southeastern United States, where the species is expected to harbor relatively high amounts of genetic variation in areas of Pleistocene glacial refuge. Nineteen allozyme markers were used to quantify the genetic variation present in 20 eastern hemlock populations in the southeastern United States. Results indicate that the species has low levels of genetic diversity in the region compared to most other conifers, but greater population differentiation (F ST = 0.126). Populations along the eastern periphery and in the Appalachian interior exhibited higher levels of diversity than those along the western periphery of its geographic range. The results suggest that the glacial refuge area for eastern hemlock was likely located east of the southern Appalachian Mountains, and indicate that ex situ conservation seed collections should be concentrated in these areas of higher diversity.}, number={2}, journal={New Forests}, publisher={Springer Nature}, author={Potter, K.

Understanding the relative importance of these factors is significant for determining management and monitoring actions that adequately protect water quality and the ecological integrity of aquatic communities. In this study, we analyzed Geographic Information System-derived data to: (1) determine whether North Carolina benthic macroinvertebrate community structure is more closely correlated with landscape characteristics at the scale of riparian zones or entire watersheds; (2) understand which landscape attributes are correlated with aquatic invertebrate communities that reflect degraded stream conditions; (3) investigate whether the importance of streamside forest varies with watershed size. Watershed characteristics explained a greater amount of variability in macrobenthic community structure (69.5–75.4%) than riparian attributes (57.4–65.2%). While topographic complexity was the most important variable at all scales, different land cover characteristics were of secondary importance at both scales: developed land cover for watersheds, and forest cover at the riparian scale. The amount of riparian zone and watershed-wide forest cover accounted for more variability in small watersheds than in large watersheds.}, number={2-4}, journal={Landscape and Urban Planning}, publisher={Elsevier BV}, author={Potter, K and Cubbage, F and Schaberg, R}, year={2005}, month={Mar}, pages={77–90} }

Nonpoint pollution sources are responsible for 70% of that degradation, and controlling nonpoint pollution from agriculture, urbanization, and silviculture is considered critical to maintaining water quality and aquatic biodiversity in the Southeast. We used an ecological risk assessment framework to develop vulnerability models that can help policymakers and natural resource managers understand the impact of land cover changes on water quality in North Carolina. Additionally, we determined which landscape characteristics are most closely associated with macroinvertebrate community tolerance of stream degradation, and therefore with lower-quality water. The results will allow managers and policymakers to weigh the risks of management and policy decisions to a given watershed or set of watersheds, including whether streamside buffer protection zones are ecologically effective in achieving water quality standards. Regression analyses revealed that landscape variables explained up to 56.3% of the variability in benthic macroinvertebrate index scores. The resulting vulnerability models indicate that North Carolina watersheds with less forest cover are at most risk for degraded water quality and steam habitat conditions.
