|
EIAs describe a systematic approach for measuring ecological condition at a variety of spatial scales. |
|
|
Summarizes information on thirty sites in the Palouse Prairie in Washington. Each site includes: (1) ecological systems; (2) ecological condition assessed by EIA rapid assessments (walking or with binoculars); and (3) a description of the biological and ecological characteristics including a stressors evaluation. |

A Riparian Vegetation Classification of the Columbia Basin, Washington |
A guide to the riparian and wetland vegetation of Washington's Columbia Basin.
|
|
A preliminary classification of native, undisturbed wetlands
found in the lowlands of western Washington. It includes impounded,
semi-impounded and tidal freshwater wetland plant communities |
|
Marine and estuarine habitats are defined by their depth, substratum type, energy level and a few
modifiers. For each combination of these physical variables, species (plants and animals) that are diagnostic
of the habitat are described. |

|
Developed by the Natural Heritage Network in conjunction with NatureServe and The Nature Conservancy, this classification is a systematic way of describing and assessing ecological diversity. |
