Ecoregions

Ecoregions denote areas within which ecosystems (and the type, quality, and quantity of environmental resources) are generally similar. They are designed to serve as a spatial framework for environmental resource management.

OVERVIEW

Ecoregion data from the Washington State Department of Ecology

Ecoregions by state were extracted from the seamless national shapefile. Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components.

Orcas without borders

The Salish Sea’s endangered southern resident orcas travel freely across the U.S.-Canada border, unconstrained by political boundaries. But while they don’t require passports, they can still face differing policies and conditions as they go back and forth between nations. We look at some of the ways that the United States and Canada compare in their efforts to protect the whales.

The Willamette Valley-Puget Trough-Georgia Basin Ecoregional Assessment

The Willamette Valley-Puget Trough-Georgia Basin Ecoregional Assessment considers 833 conservation targets identified by expert teams, proposing that if those targets are represented in an ecoregion, a majority of species, including those which lack data, will be included.

The Puget Lowland ecoregion

Ecoregions provide a useful framework and background for the discussion of marine, freshwater, and terrestrial environs of the county. The discussion of ecoregions is based on U.S. Environmental Protection Agency (EPA) ecoregion conventions, which result in units similar to European biogeographical regions because they denote areas of general similarity in ecosystems.
