Project Number: 5360-11630-006-00-D
Project Type: In-House Appropriated
Start Date: Sep 10, 2007
End Date: Sep 9, 2012
1) Evaluate the effects of fire, mechanical treatments, livestock grazing, introduced invasive weeds, western juniper expansion, and climate on the vegetation and watershed function of sagebrush steppe rangelands. 2) Improve our understanding of livestock behavior and livestock/environment interactions. Improve tools to manipulate livestock behavior and grazing patterns. 3) Understand mechanisms of weed invasion and develop management strategies that can be used to restore rangelands that have been degraded by weeds or other disturbances.
The mission of the Burns unit is to provide the science for sound land and livestock management. This five-year plan builds on a rich history of research at this location, in some cases reaching back to the 1940's. Rangelands of the Great Basin are spatially variable and land ownership patterns are a complex mix of public and private land. Annual weather variation is high, and can obscure vegetation responses to management treatments. Ranching forms the basis of the regional economy, underscoring the importance of forage production, and the large percentage of public land in the region translates into public scrutiny of management actions, and a focus on environmental impacts and biodiversity. Invasive species and expanding juniper populations represent major threats to existing land uses and values. Our research program has evolved with substantial public input and addresses questions raised by our customers. Land managers in this region are faced with information gaps in basic sagebrush steppe ecology, vegetation responses to management actions, plant community restoration, seedling establishment and livestock grazing management. Our research program will fill some of those gaps while expanding and enhancing current ecological theory and building on our long-term data sets. The unit also has a commitment to synthesizing research information and developing management tools. Formerly 5360-11630-005-00D (1/08).
