Status and Viability of Species of Conservation Concern

Understanding how patterns of abundance, productivity, distribution, and diversity influence population and species viability is essential for evaluating the impacts of management actions and environmental change on species of conservation concern. Team scientists assess the status of species of conservation concern using proven and innovative approaches from viability analysis, risk assessment, and decision theory to provide a technical basis for developing conservation strategies and recovery plans. The primary objectives of this research are to provide a robust evaluation of current status of conserved species, to understand the factors that are limiting to viability in nature, and to identify likely future trends.
