Later the name was adopted by David McCloskey, a Seattle University sociology professor, to describe it as a bioregion. McCloskey describes Cascadia as "a land of falling waters."
Soils are warmer here than in higher elevation ecoregions, and it is one of the most important timber producing areas in the Pacific Northwest. The steep valleys trending to the west contain high and medium gradient rivers and streams that support cold water salmonids, including the threatened Chinook salmon, steelhead, and bull trout.
The Pacific temperate rainforests lie along the western side of the Pacific Coast Ranges along the Pacific Northwest Coast of North America from the Prince William Sound in Alaska through the British Columbia Coast to Northern California, and are part of the Nearctic realm, as also defined by the World Wildlife Fund.

The grizzly bear is a keystone species found in this region. As an "ecosystem engineer", they regulate the species they prey on, disperse plant seeds, aerate the soil as they dig, and bring salmon carcasses into the forest. [2] The dominant fish species of the region, in which the grizzly bear preys on, is pacific salmon.
The Pacific Northwest is a diverse geographic region, dominated by several mountain ranges, including the Coast Mountains, the Cascade Range, the Olympic Mountains, the Columbia Mountains, and the Rocky Mountains. The highest peak in the Pacific Northwest is Mount Rainier, in the Washington Cascades, at 14,410 feet (4,392 m).
Whereas many current regional informatics initiatives focus much of their attention on information management of non-living resources, PBIF invests wholly in the information management of Pacific island organisms. PBIF is designed to aggregate, organize, and disseminate available biodiversity data in an electronically accessible information ...
