www.npwrc.usgs.gov — This resource is a species profile of the purple loosestrife (Lythrum salicaria), which is considered an invasive plant species. Its displacement of native species in wetlands has led to the loss of suitable habitat for wildlife. L. salicaria is the only reddish-purple flowered plant to develop massive monospecific blocks of showy floral displays More...

www.werc.usgs.gov — The Fire and Fire Surrogate study is a network of 13 long-term sites established nationwide to evaluate the ecosystem impacts of different fire hazard reduction treatment in forests that historically experienced short-interval, low- to moderate-severity fire regimes. The fuel reduction treatments being investigated by USGS researchers at Sequoia More...

www.fort.usgs.gov — This resource has been developed to provide source materials on the history of the invasion, continuing threats, research results, and containment and management of the brown Treesnake (Boiga irregularis) in Guam and its relevance to other islands and mild continental environments. Users can report snake sightings on this website, get information 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...

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...

fresc.usgs.gov — The National Park Service has stated that declining amphibian populations are the top priority for research in the National Park System. Salamanders are a native vertebrate predator in high-mountain lakes throughout the western US, especially in many small lakes naturally barren of fish. This issue overview demonstrates the potential for using More...

fresc.usgs.gov — Little is known about the amphibian taxa associated with streams, lakes, ponds, and wetlands in Mount Rainier National Park (MORA). This issue overview addresses the concerns about the possible impacts of introduced trout on amphibian taxa, and park management's interest in documenting current distribution and abundance of amphibian taxa in the More...

fresc.usgs.gov — Fish introductions have been implicated in the disappearance of amphibian communities and in the alteration of zooplankton communities. Furthermore, the presence and abundance of amphibian larvae and zooplankton in mountain lakes are directly related to nutrient concentrations in the aquatic environment, as well as enhancement to recreational More...

www.werc.usgs.gov — Native amphibian and reptile populations worldwide are under threat from exotic invasive species of plants and animals, including other reptiles and amphibians. As habitats are changed and plant community organization is modified by exotic species, delicate relationships between plants and animals are altered or eliminated, creating a negative More...

srfs.wr.usgs.gov — The Snake River Birds of Prey National Conservation Area (NCA) has undergone massive habitat changes since 1980. Occupancy and productivity data have been collected at all eagle territories in the NCA since 1971, providing a wealth of background information. This issue overview continues the long-term assessments of territory occupancy and More...
