Summarizes work completed to assist the Bureau of Land Management in the development and implementation of a science-based adaptive management and monitoring program to evaluate progress toward objectives established in BLM’s Resource Management Plan. Includes 1) an analysis of data collected between 1995 and 2004 on the condition and trend of the NCA’s grasslands, 2) a review of monitoring protocols, and 3) an outline of the adaptive management process implemented by BLM in 2004/2005.

Mapping the Status of River Streams
Wet/dry mapping provides a low-cost, river-wide snapshot of hydrologic conditions for rivers with interrupted perennial surface flows.
The Nature Conservancy, in collaboration with the Western Water Assessment and the USDA-Agricultural Research Service, has produced a snowtography handbook to support resource managers, researchers, and practitioners seeking to understand how the arrangement and density of trees, or the size and sev[…]

Tree mortality response to drought-density interactions suggests opportunities to enhance drought resistance
A future of hotter temperatures and less precipitation under climate change could increase tree mortality under drought conditions in dry forests across the western U.S., causing large-scale tree die offs. Restoration projects that reduce densities of overgrown forests can result in lower competit[…]
