www.npwrc.usgs.gov — This research project evaluates the effects of prescribed fire on the biological control of an invasive species, leafy spurge (Euphorbia esula). This project evaluates the effect of prerelease burning on establishment of flea beetle (Aphthona nigriscutis) colonies and the ability of established colonies to survive prescribed fire.

fresc.usgs.gov — Periodic fire is a natural part of sagebrush steppe ecosystems in the Great Basin. However, a suite of human-caused factors has dramatically changed fire regimes in many of these systems. Decades of fire suppression and livestock grazing have produced dense, single-aged sagebrush stands and invasion by cheatgrass (Bromus tectorum) has increased More...

sbsc.wr.usgs.gov — The Internet Map Server (IMS) visually displays the non-native, invasive plants (weed) occurrences in the current (2003) SWEMP database. An IMS allows you to interactively draw, query, and print maps. The SWEMP IMS was developed from ESRI's ArcIMS presentation product.The Southwest Exotic Plant Information Clearinghouse is a cooperative effort More...

www.werc.usgs.gov — This web resource addresses the positive relationship between cheatgrass (Bromus tectorum) and fire frequency as a major concern for land managers in semi-arid shrublands throughout western North America, particularly in Great Basin sagebrush steppe. Management tools are needed to break this cycle, and in this project we will evaluate the use of More...

www.werc.usgs.gov — Where nonnative plant species have invaded wildlands or have potential to invade, fire may influence their abundance and the effects of the nonnative species on native plant communities. USGS scientists and colleagues have contributed chapters to a volume that synthesizes scientific information regarding wildland fire and nonnative invasive plant More...

www.werc.usgs.gov — This resource provides an overview of the research on ways to prevent invasive annual grass invasions and restore invaded habitats, which has independently and repeatedly been identified by all land management agencies as a top national research priority. Annual grasses have invaded a number of shrub and forest ecosystems in western North America More...

www.werc.usgs.gov — The sage grouse that occupies the Mono County area is described as the eastern subspecies of the greater sage-grouse (Centrocercus urophasianus urophasianus). The greater sage-grouse (Centrocercus urophasianus) is found in sagebrush (Artemisia spp.) dominated habitats across western North America. Sage grouse populations have declined dramatically More...

www.nbii.gov — Natural resource managers face complex decisions that require a clear understanding of the status of wildlife populations and their habitats. Monitoring is key to making effective management decisions and evaluating the outcomes of those decisions. The goal of NRMP is to improve the accessibility of monitoring efforts to resource managers to aid More...

www.fort.usgs.gov — Natural Resource Monitoring Partnership (NRMP) is a collaborative effort by the natural resource management community to improve monitoring efforts in order to support effective evaluation and decision-making by sharing information on monitoring projects and protocols. The Natural Resource Monitoring Partnership was built for easy access to More...
