This is a project to acquire privately owned properties eligible for inclusion in the West Tiger Mountain Natural Resources Conservation Area (NRCA) in King County. Properties proposed for acquisition are immediately threatened with conversion to residential uses incompatible with the viability of this important urban wildlife area. Distinctive physical features of this site include talus caves, two lakes, three stream systems, forested wetlands, and old growth Douglas-fir forests. The acquired properties will preserve critical wildlife habitat, open space and scenic vistas along the I-90 corridor and provide opportunities for low-impact recreation and outdoor environmental education. West Tiger Mountain is a conservation area with immense regional and local importance.
