Category count models for adaptive management of metapopulations: Case study of an imperiled salamander

CONSERVATION SCIENCE AND PRACTICE, 2(4).

By: . Katherine M. O'Donnell *, P. Fackler n, F. Johnson *, M. Bonneau *, J. Martin * & S. Walls *

author keywords: adaptive management; Ambystoma; amphibian; decision analysis; endangered species; flatwoods salamander; Markov decision process; stochastic dynamic programming
TL;DR: The simulated metapopulation dynamics using the resulting optimal management policy found that under model FSQ, occupancy steadily declined over time, indicating that populations would rapidly become extirpated; with model EMA, occupancy remained stable, suggesting that populations will persist only if additional actions are applied and are effective.
