Critical Habitat for Endangered Species in Washington

Critical Habitat for Endangered Species in Washington State:

With the new federal definition change of habitat, I wanted to create a map that shows just how much federal land (the green areas) is in Washington. Turns out, it’s about 20% or ~12 million acres. I also wanted to see how much of that federal land, and waters, are designated as critical habitat (the pink areas). As you can see, it’s quite significant.

Habitat loss remains the leading driver of extinction. Many of these landscapes remain connected through forests, wildlife area, parks, and tribal lands, creating wildlife corridors that support migration, breeding, and long-term resilience.

In the state, there are ~50 animal species state listed as sensitive, threatened, or endangered, with 268 additional animal species of concern. Also on the docket are 3 endangered plants, 6 threatened, and nearly 400 plant species of concern.

Since 1973, the Endangered Species Act has recognized that destroying habitat can “harm” endangered species because they depend on these places for breeding, feeding, shelter, and recovery. The new federal rule removes habitat destruction from that definition of “harm” despite habitat loss being the primary threat facing most endangered species.
