Biodiversity - Species of Interest in King County

Each species group page features information relevant to the species of King County.

Regulated Species

Many wildlife and invertebrate species found in King County are protected under the County's Critical Areas Ordinance and policies found in the King County Comprehensive Plan. Lists of King County Species of Local Importance are on our Regulations page (it changes based on State and Federal status of animals). The Regulations page also discusses Federal wildlife laws, which also apply to wildlife in the County.

Urban Wildlife

Urbanization is a primary threat to our native biodiversity, and our Urbanization and Biodiversity page discusses the problems associated with urbanization, as well as what King County is doing about it. It also addresses wildlife issues in both urban areas and those areas that are currently being developed ("urbanizing"). Read about how to intentionally create wildlife habitat as well as learn what wildlife may show up in your back yard when you least expect it.
