Trout Unlimited developed three conservation planning products to help identify strategic conservation opportunities and evaluate potential projects within the range of Eastern Brook Trout in the eastern United States. The Conservation Portfolio uses the 3-R framework (Representation, Resiliency, and Redundancy) to evaluate each population patch for resiliency to disturbances, likelihood of demographic persistence, and representation of genetic, life history, and geographic diversity. The range-wide habitat integrity and future security assessment uses broad-scale GIS information to characterize the general habitat condition and vulnerability of brook trout patches. The focal area analyses add regional data sources to provide additional resolution on habitat condition and threats within specific geographies. Taken together, the products allow us to characterize the continuum of viability, habitat condition, and vulnerability of populations and the corresponding conservation strategies they likely require. This project was supported by funding from the National Fish and Wildlife Foundation.
