1a.Objectives (from AD-416):
The Bureau of Land Management (BLM) manages 13.5 million acres of public land in New Mexico. The mission of the BLM is to sustain the health, diversity, and productivity of the resources and land entrusted to it for the use and enjoyment of present and future generations through balanced management within the framework of the laws. To meet the goals of the BLM mission, the agency must have reliable sources of sound science concerning rangeland resources within its jurisdiction in support of the Bureau's overall vegetation management program, and rangeland health assessment and evaluations.
1b.Approach (from AD-416):
1) Provide landscape stratified protocols, with control sites for evaluation of landscape-scaled brush controled treatments. . 2)Evaluate new research-based soil-plant-endophyte technologies to enhance establishment of perennial grasses on disturbed Chihuahuan desert rangelands.
In FY 2012, ARS continued mapping of brush control areas across the Las Cruces District and assisted BLM in establishing monitoring sites and additional 20 locations (now numbering over 100). A study of bird community responses to brush control was completed and a paper is being produced. A second reading of an early set of transects (2007) was reread, providing the first multi-temporal data on brush treatments. The ARS Unit and BLM had frequent e-mail, telephone communication, meetings and field site visits discussing, collaborating, and establishing monitoring sites.
