One of the initial efforts, was the Gap Analysis Project, which sought to provide broad geographic information on the status of ordinary species (those not threatened with extinction or naturally rare) and their habitats in order to provide land managers, planners, scientists, and policy makers with the information they need to make better-informed decisions.

Wildlife distribution products and other wildlife information from INR are available from the Oregon Explorer and the Oregon Wildlife Viewer where you can search for species information and distribution maps.
