Developing searchable annotated bibliographies for resource managers

Resource management decisions need to be informed by up-to-date, quality science and data. However there is sometimes an overwhelming number of scientific publications for managers to consider in their decisions. This project provides concise summaries of recent, peer-reviewed science and data products about different resources and topics of management concern, integrated into a searchable tool.

Understanding and fostering use of habitat models for rare plants in Bureau of Land Management planning and management decisions

The use of rare plant habitat models in public lands decisions can be hampered by factors such as a lack of understanding of or confidence in underlying data, a lack of access to models, and a lack of opportunity for model use in decisions. This project seeks to explore and suggest potential solutions to these challenges, facilitating greater use of habitat models in public lands decision-making.

Assessing Threats to Conservation Priority Areas in State Wildlife Action Plans

States across the U.S. have developed Wildlife Action Plans, with the purpose of preventing future listings under the federal Endangered Species Act. Habitat loss and fragmentation are key threats to wildlife in the U.S., and housing development is a major driver of both. USGS is working to quantify the vulnerability of and threat to priority areas in State Wildlife Action Plans from future...

Species Conservation

Large scale changes are occurring to our natural landscapes, often resulting in changes to the distribution and abundance of species living within these landscapes. Populations of many species affected by these natural or anthropogenic changes require focused management to ensure their conservation and sometimes recovery from the brink of extinction.

Grassland Ecology and Conservation

Grasslands are arguably one of the most anthropogenically stressed ecosystems of the western United States. The highly endangered black-footed ferret and prairie dogs epitomize grassland mammals of high conservation concern.

Population Genetics

Population genetics is an area of research that examines the distribution of genetic variation and levels of genetic diversity within and between populations. This information provides insights into the level of connectedness of populations throughout a species’ range and can be used to identify unique populations or those with low levels of genetic diversity.

Taxonomic Uncertainty

Taxonomic uncertainty can be assessed using genetic data, along with other lines of evidence (such as morphological and behavioral characteristics). Such data can be used to identify and assess taxonomic boundaries (species, subspecies, hybrids) and in many cases redefine them. Such delineations are highly relevant for species status determinations (endangered, threatened, or at-risk).
