Puget prairie

Puget prairie, also known as South Sound prairie or South Puget Sound prairie, is an endangered type of prairie found along the southern coast of the Puget Sound in northwestern Washington, in the United States. It is home to many endemic species, and is threatened greatly, with under 10% of the native prairie remaining.^[1] The prairie was formed due to receding glaciers from the last ice age, which left behind large areas of drained and gravelly soil. Puget prairie once covered almost 150,000 acres of modern Washington, but due to suppression of natural and controlled fires, encroachment of non-native plants, and human development, it receded to its modern size, far smaller than its pre-contact range.^[1]
