The WSF works in an area of high topographic and climatic variability. This creates a great diversity of plant communities ranging from alpine meadows to mixed forests to marshland. This area is also home to the endangered white bark pine which is a key food source for grizzlies and nutcrackers. Other at-risk species in the area include birdfoot buttercup, five-leaved cinquefoil, narrow-leaved goosefoot and small-fruited willowherb. It is important to conserve this area as it is an important stronghold for many ecosystems found in BC.
