Citizen science, an emerging research approach which involves active public participation and collaboration with scientists in the scientific process, is an innovative tool that could help managers address these challenges. This study applied the Preferred Reporting Items for Systematic Review Recommendations (PRISMA) protocol to review published studies that utilized citizen science methods in recreation research, examining the extent and nature of such applications and identifying future opportunities. We identified 20 peer-reviewed journal articles from the Web of Science, most of which were published since 2015. These studies utilized different citizen science approaches to examine recreation patterns, behaviors, and impacts in terrestrial and marine PAs. We found that citizen science was used most often in marine PAs, with specialized recreationists (e.g., SCUBA divers) as the most frequent contributors. The types of volunteers recruited differed by their sources (i.e., general public, recreation specialists, and organizational affiliates) and roles (i.e., volunteers as agents of data collection and volunteers as research subjects), with innovative technology (e.g., participatory GIS) creating new engagement opportunities. Despite these benefits, the accuracy and reliability of citizen science data remain important considerations for managers. Our review demonstrates how citizen science can inform management and enhance public participation in PA stewardship activities, and it reveals the need for more research to explore applications of citizen science in different recreation contexts.}, journal={Journal of Environmental Management}, publisher={Elsevier BV}, author={Cheung, Suet Yi and Leung, Yu-Fai and Larson, Lincoln R.}, year={2022}, month={Mar}, pages={114353} }

We compared changes in land cover, surface albedo, and surface temperatures between the Imperial Sand Dunes Recreation Area (ISDRA) and areas with no OHV activity in the North Algodones Dunes Wilderness area (NADW). Both areas showed a decreasing normalized difference vegetation index (NDVI) and an increasing albedo from 2001 to 2016; however, ISDRA had a lower NDVI value and higher albedo compared to the adjacent NADW. Transects across these adjoining areas revealed substantial differences in daytime and nighttime land surface temperatures. ISDRA had an appreciably higher mean daytime temperature and a lower mean nighttime temperature compared to those within NADW. Results suggest direct association between increasing OHV activity and reduced vegetation cover, increased soil exposure, and higher daytime temperatures in the Algodones Dunes. We recommend enhanced monitoring of ecosystem and land use changes coupled with enhanced land use management to reduce the contributions of recreational OHV activity on land degradation and to maintain habitat for key species and ecosystems of interest in the dune field.}, journal={JOURNAL OF ARID ENVIRONMENTS}, author={Cheung, Suet-Yi and Walker, Ian J. and Myint, Soe W. and Dorn, Ronald I.}, year={2021}, month={Feb} }
