2008 Annual Report 1a.Objectives (from AD-416) The objective of this cooperative research project is to (1) describe ecological processes that characterize the functioning of the Chihuahuan Desert, (2) identify, evaluate and describe methods for monitoring rangeland conditions, (3) develop techniques for remediation of degraded rangeland, and (4) design new technologies for management of grazing livestock in arid landscapes. 1b.Approach (from AD-416) Approach emphasizes interdisciplinary research funded by several extramural sources. Objective 1 is shared by the National Science Foundation Long-Term Ecological Research project at the Jornada. We have well established this environment. Objective 2 is shared by the Department of Defense and we are identifying indicators of rangeland health for rapid monitoring of resource conditions. Objective 3 is shared by the Bureau of Land Management where we are evaluating the use of prescribed burning as a management tool for maintaining desert grasslands. Objective 4 is shared by the Natural Resources Conservation Service where we are developing new technologies to control livestock movement on open ranges and rapidly identify botanical composition of grazing animal diets. 3.Progress Report Monitoring activities addressing research progress will be conducted throught the year with new Mexico State University faculty and staff through seminars, symposia, workshops and meetings. This is a new agreement for a 5-year period through 2013, but continues research collaboration that initiated in 2002.
