Terrestrial Habitat
Indicator
King County's Terrestrial Habitat Index is derived from two main groupings of results regarding amounts of forest cover and impervious surface. Our weighting system applies 50 percent each of the forest cover and impervious surface results. Although plant biodiversity is recognized as a relevant contributor to the overall quality of terrestrial habitats, it is not included because there is no data being collected regarding the types and numbers of plants in King County.
Status
Unincorporated King County is reaching unofficially established goals of maintaining 65 percent or more in forest cover and less than 10 percent impervious surface. It is difficult to assess the condition of terrestrial habitats in urban areas, since no goal has been set for the amounts of impervious surface and forest cover, and no data exits for plant biodiversity.
Influencing factors
Over the past two centuries, increased population and development have substantially altered King County's landscape. Less forests and natural land cover increase the need for manmade stormwater controls and reduce the amount of habitat for animal and plant species.
Existing DNRP response
Land-use regulations were recently updated as part of the Critical Areas Ordinance, which was passed in 2004. These regulations attempt to maintain a minimum of 65 percent forest cover and limit impervious areas to less than 10 percent in rural, unincorporated King County. They also provide extra protection for aquatic riparian areas.
Priority new actions
Under a rural stewardship plan, property owners can develop their property, while still protecting critical areas on a site-specific basis. Rural stewardship plans are developed to protect critical areas while balancing the needs of property owners.
What you can do
Plant trees and reduce impervious or hard surfaces by using pervious pavers in drive and walk ways. Encourage your local city or town to make tree protection regulations stronger. Why trees? Shade for streams? Habitat for native species? What kind of trees?
