September 2008 | Publisher: Other Federal Agency (United States Forest Service (USFS)) | Format: .PDF
www.fs.fed.us — This review of information on relationships between wildland fire and nonnative invasive plants can assist fire managers and other land managers concerned with prevention, detection, and eradication or control of nonnative invasive plants. The 16 chapters in this volume synthesize ecological and botanical principles regarding relationships between More...

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...

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.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 — 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...

www.werc.usgs.gov — This project investigates the role of pre-fire fuel reduction manipulation projects on the invasion of nonnative plants. This study is designed to answer the following questions: 1. Do nonnative plants become established within fuel breaks? 2. Are some types of fuel breaks less likely to support nonnative species? 3. Do fuel breaks promote the More...

www.werc.usgs.gov — This web resources discusses the awareness of modern ecologists of the problems caused by the invasion of exotic species into natural areas and the associated negative effects on global patterns of native biodiversity. Once established, some exotic species have the ability to displace or replace native plant and animal species, disrupt nutrient More...
