Terrestrial Ecological Evaluation Process - Simplified or Site-Specific Evaluation?

If none of these circumstances apply to your site, you may conduct a simplified ecological evaluation.

  Terrestrial Concern Response  (Circle One)
*1 Is the site is located on or directly adjacent to an area where management or land use plans will maintain or restore native or semi-native vegetation?

Yes / No

*2a Is the site used by a threatened or endangered species? Yes / No
*2b Is the site used by a wildlife species classified by the state department of fish and wildlife as a "priority species" or "species of concern" under Title 77 RCW? Yes / No
*2c Is the site used by a plant species classified by the Washington state department of Natural Resources natural heritage program as "endangered," "threatened," or "sensitive" under Title 79 RCW. Yes / No
*3 Is the site (area where the contamination is located) located on a property that contains at least ten acres of native vegetation within 500 feet of the area where the contamination is located? Yes / No
4 Has the department determined that the site may present a risk to significant wildlife populations? Yes / No

*1    This includes for example, green-belts, protected wetlands, forestlands, locally designated environmentally sensitive areas, open space areas managed for wildlife, and some parks or outdoor recreation areas. This does not include park areas used for intensive sport activities such as baseball or football.

*2a    What are the threatened or endangered species in Washington state?

*2b    Which plant species are classified as threatened, endangered, or sensitive?  Where can I find out more information about this topic?

*2c    For plants, "used" means that a plant species grows at the site or has been found growing at the site.  For animals, "used" means that individuals of a species have been observed to live, feed or breed at the site.

*3    For this analysis, do not include native vegetation beyond the property boundary.

Hitchcock, C.L. Hitchcock, J.W. Thompson and A. Cronquist, 1955-1969, Vascular Plants of the Pacific Northwest Areas planted with native species for ornamental or landscaping purposes shall not be considered to be native vegetation.

(Here's a link to the Seattle Public Library  and the Washington State Library to borrow a copy of Natural Vegetation of Oregon and Washington, J.F. Franklin and C.T. Dyrness, Oregon State University Press, 1988, or you may purchase it through your favorite bookseller.  Here's an additional link to a useful online Field Guide to Selected Rare Plants of Washington developed by the Washington State Department of Natural Resources' Natural Heritage Program (WNHP) and the Spokane District of the U.S.D.I. Bureau of Land Management (BLM) which contains fact sheets for 139 vascular plant species and one lichen species.

Here is an aid to calculating area  and an aerial photo depicting a site, its 500 foot boundary and several labeled circles identifying various areas for reference in judging the area of native vegetation within the 500 foot radius.
