On March 14, 2010 the Eastern Native Tree Society and Western Native Tree Society switched from discussion lists on Google Groups to a new discussion list in a Bulletin Board format at:   Posts made since the inception of the BBS on March 14, 2010 will be sorted and archived on the BBS. Click on the link to go to the equivalent section on the new BBS. This website will continue to serve as a front end for the ENTS and WNTS groups. It will continue to serve as a repository of older posts, and will serve as the host site for special projects and features that are not well suited for a BBS format. Please visit the BBS for the latest information and trip reports.

Pacific Northwest Old Growth Forest The Pacific Northwest old-growth forest is a conifer forest, dominated by large, old trees. In the Pacific Northwest, the most common type of old-growth ecosystem is forests dominated by Douglas-firs and western hemlocks, generally 350 to 750 years old. The youngest old-growth forests are 200 years old, and the oldest are about 1,000 years old.- The Pacific Northwest also has old-growth forests dominated by Sitka spruce and western hemlock, along the Pacific Coast, and at higher elevations in the Cascade Mountains, true fir and hemlock old-growth forests. 

Where the Pacific Coast Old-Growth Forests Are Found The Pacific coast old-growth forests are found only in parts of western North America--the area from southeast Alaska and southwest British Columbia, down through western Washington, western Oregon, and the edge of northern California; and from the Pacific Ocean inland to the crest of the Cascade Range.   Old-growth forests do not cover all the land in this area. Many of the forests are younger. Other types of ecosystems are found in the valleys and along rivers.

Native Forest Network The Native Forest Network is a global autononomous collective of forest activists, indigenous peoples, conservation biologists and non-governmental organizations. It functions on a consensus basis, and is non-violent, non-hierarchical and non-patriarchal. Furthermore, it is non-discriminatory on grounds of race, gender, culture, class or species. Mission: To protect the world's remaining native forest be they temperate or otherwise, to ensure they can survive, flourish and maintain their evolutionary potential.

DIVERSITY AND STATE OF FOREST ECOSYSTEMS IN THE PACIFIC NORTHWEST by Yaroslaw Medwidsky The Pacific Northwest has a tremendous wealth of natural resources with spectacular forests, expansive rangelands, and plentiful salmon, having drawn people from throughout the country for more than a century (Smith et al. 1995). The complex physiography, geology, soils and climate of the Pacific Northwestern United States (US) (Kolb and Bailey 2003) have created conditions conducive to such biotic and genetic diversity...Physiography and Forest Ecosystems of the Pacific Northwest Region: There are four primary ecosystems in the Pacific Northwest region: forest ecosystems west of the Cascade Range (commonly called the Westside); forest ecosystems east of the Cascade Range (commonly called the Eastside); Eastside rangeland ecosystems; and riparian and aquatic ecosystems containing anadromous fish populations (Smith et al. 1995).
