Cook Inlet: The Cook Inlet Basin ecoregion comprises the low-lying basin surrounding Cook Inlet from the south side of the Alaska Range to Kachemak and Tuxedni Bays. The ecoregion covers 3,792,310 hectares, including the western half of the Kenai Peninsula, the Anchorage bowl, the western Cook Inlet lowlands, and the Susitna lowlands. The marine component is 886,200 hectares, and the terrestrial and freshwater portions are 2,906,110 hectares.

Puget Trough: In the Puget Trough — Georgia Basin ecoregion, researchers compared the outcomes of separate and integrated planning across terrestrial and nearshore marine environments. This ecoregion is a long ribbon of broad valley lowlands and inland sea flanked by the rugged Cascade and coastal mountain ranges of British Columbia, Washington, and Oregon.

Pacific Northwest Coast: The coastal zone along the Pacific Northwest encompasses both the Puget Trough and Cook Inlet areas. This area was chosen for a planning exercise that integrated targets across terrestrial and marine locations and then tested those targets separately. The analysis included 387 targets (e.g., species, habitats) of which 55% were terrestrial and 45% marine.
