Report on the Biological Planning Process for Livestock Management at Las Ciénegas (May 2006)

Jointly authored by BLM and TNC, this report summarizes the monitoring information used and decision-making process for the 2005-2006 grazing plan at Las Ciénegas National Conservation Area. The report details how BLM, with input from partners, advisory teams, and the grazing permittee, are using upland monitoring data and pasture reconnaissance to make grazing management decisions.

Biotic Communities of the Southwest GIS Layer (January 2006)

TNC developed a digital version for the whole of David E. Brown and Charles H. Lowe’s 1981 map. Previously, GIS representations of this map were only available for its Arizona and New Mexico portions. Users: please note the relatively coarse source scale of the paper map (1:1,000,000) when using this digital version for analyses. A layer file (.lyr) which mimics the familiar color scheme of the paper map is also provided.

Huachuca Area Fire Partners Fire Management Plan (November 2005)

The Huachuca Area Fire Partners, an alliance of public and private groups in southeastern Arizona, came together to restore and manage fire activities over a 500,000-acre area that includes the Huachuca Mountains and surrounding grasslands. The Fire Management Plan provides a framework for landscape-level fire management — its goals include collectively implementing fire management projects that participants are unable to accomplish on their own and managing fire across jurisdictional boundaries.

State of the Las Ciénegas National Conservation Area, Part I (July 2005)

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.

Conservation Elements of and a Biodiversity Management Framework for the Sonoran Desert National Mon (June 2005)

Developed for the BLM and Dept. of Defense, this report summarizes the results of The Nature Conservancy’s characterization of important biodiversity elements and the Sonoran Institute’s analysis of socioeconomic information for the Monument and surrounding environs. The data and analyses demonstrate the importance of coordinated management among the various public, private, and tribal land managers surrounding the National Monument as a mechanism for protecting the objects for which the Monument was designated.

The Impacts of Livestock Grazing in the Sonoran Desert: a Literature Review and Synthesis (February 2005)

Prepared for the BLM, this review includes a synthesis of the scientific literature on the impacts of livestock grazing and grazing management strategies for the Sonoran Desert. Also included are reviews of plant community dynamics, biological soil crust ecology, and grazing-vegetation interaction theory as they relate to an understanding of grazing impacts and strategies.

The Lower San Pedro River—Hydrology and Flow Restoration for Biodiversity Conservation (May 2004)

Describes The Nature Conservancy’s flow management approach to increasing water supply for riparian vegetation, based largely on results from hydrologic analyses indicating that retiring agricultural pumping at key locations increases water availability for riparian vegetation. Paper presented at USFS conference, May 11-15, 2004.
