Current Projects

CEG is working with our partners at the EcoStudies Institute and the University of Washington to explore the potential effects of multiple interacting stressors on five at-risk populations using a scenario-based modeling approach.  

At-risk species often face multiple, interacting stressors. Although many stressors have been studied in isolation, relatively little is known about how interacting stressors affect populations. CEG is developing spatially explicit, individual-based, population models of the Golden-cheeked Warbler (Setophaga chrysoparia) and Black-capped Vireo (Vireo atricapilla) at Fort Cavazos, and the Streaked Horned Lark (Eremophila alpestris strigata), Mazama pocket gopher (Thomomys mazama), and the Taylor’s checkerspot butterfly (Euphydryas editha taylori) at Joint Base Lewis-McChord (JBLM). Our research tasks include model building and parameterization, stressor scenario development, and model simulation.  Project results will provide guidance for the management of five at-risk species on two different installations in the face of multiple, interacting stressors.
