Improving Southwestern Riparian Areas Through Watershed Management PDF Download

Excerpt from Southwestern Riparian-Stream Ecosystems: Research Design, Complexity, and Opportunity The last area, a group of six streams, lies below the Mogollon Rim in central Arizona. Six perennial first order streams (pine, Dude, Bonita, Ellison, Christopher, and Horton creeks) issue from a major fault block (rinne and Medina Historically, these watersheds have been subjected to varied grazing and timber management practices. Pine Creek, at one end of the use spectrum, has not been grazed or logged for 25 years. In contrast, the Horton Creek watershed has been grazed season-long and continuously (may - October), and timber has been harvested on the watershed for years. The other watersheds are within grazing allotments and timber management areas that fall between these two extremes. Studies were initiated to establish baseline information to evaluate proposed changes in grazing management. In june 1990, a -ha natural wildfire (the Dude Fire) dramatically altered three of the six watersheds in this area. This natural event combined with eventful pretreatment data provided an excellent opportunity to evaluate natural and artificial effects on the structure and functioning of riparian areas.
