Ecoregional assessments provide a regional scale, biodiversity-based context forimplementing conservation efforts. The intent of the assessments is to create a sharedvision for agencies and other organizations at the provincial or state, regional, and local levels to form partnerships and ensure efficient allocation of conservation resources. The assessments identify a portfolio of sites for conservation action with a goal of protecting representative biodiversity and ecologically significant populations. These assessments are the result of rigorous scientific analyses, which incorporate expert review, and are the most comprehensive and current efforts to set conservation priorities at an ecoregional scale.

A GIS-based analysis was used to model habitat connectivity in the three Okanagan Regional Districts in British Columbia: the North Okanagan Regional District, the Central Okanagan Regional District and the Regional District of Okanagan-Similkameen. This model integrated a series of parameters to identify connected and potentially fragmented habitats. The model was not specific to a particular species. The goal was to identify portions of the landscape offering a higher opportunity for wildlife movement at a regional scale. The following parameters were used to model connectivity corridors: Elevation – Lower elevations (i.e., the valley) receive higher scores; Slope – Steep slopes receive lower scores; Terrain Ruggedness...

This data release provides access to a low-altitude, aeromagnetic survey of a part of central Washington, an area that includes the city of Wenatchee and the towns of Entiat, Chelan, and Leavenworth. The Wenatchee aeromagnetic survey extends westward from the Columbia Plateau to the Cascade Range, and covers a part of the Columbia River and Lake Chelan. The survey was conducted between October 17 and December 5, 2011, by Firefly Aviation Ltd., working under contract to the U.S. Geological Survey. Total magnetic field values were acquired using a fixed-wing aircraft flown at a target elevation of 150 m above terrain and along flight lines and tie lines spaced 400 m and 4000 m apart, respectively. Flight lines were...
