C. Ashton Drew

Research Coordinator
David Clark Labs Rm 219A

Ashton is a landscape ecologist who develops spatially-explicit models and data collection strategies in support of adaptive management. Many of her projects focus on developing methods to step-down wildlife habitat and population objectives from broad regional plans to local actions. She works closely with Louise to ensure that the modeling methods are suited not only to the available data, but also to the funding agency's conservation vision, scope, and objectives.
