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.

Field Trips and Discussions

Grand Canyon National Park Grand Canyon National Park, a World Heritage Site, encompasses 1,218,375 acres and lies on the Colorado Plateau in northwestern Arizona. It is considered one of the finest examples of arid-land erosion in the world. The Canyon, incised by the Colorado River, is immense, averaging 4,000 feet deep for its entire 277 miles. It is 6,000 feet deep at its deepest point and 15 miles at its widest.  The Park contains several major ecosystems. Its great biological diversity can be attributed to the presence of five of the seven life zones and three of the four desert types in North America. The five life zones represented are the Lower Sonoran, Upper Sonoran, Transition, Canadian, and Hudsonian. This is equivalent to traveling from Mexico to Canada. The Park also serves as an ecological refuge, with relatively undisturbed remnants of dwindling ecosystems (such as boreal forest and desert riparian communities). It is home to numerous rare, endemic (found only at Grand Canyon), and specially protected (threatened/endangered) plant and animal species. Over 1,500 plant, 355 bird, 89 mammalian, 47 reptile, 9 amphibian, and 17 fish species are found in the park.
