Critical habitat lines - Mississippi River BasinWhen a species is proposed for listing as endangered or threatened under the Endangered Species Act, the U.S. Fish and Wildlife Service must consider whether there are areas of habitat believed to be essential the species’ conservation. Those areas may be proposed for designation as “critical habitat.” Critical habitat is a term defined and used in the Act. It is a specific geographic area(s) that contains features essential for the conservation of a threatened or endangered species and that may require special management and protection. Critical habitat may include an area that is not currently occupied by the species but that will be needed for its recovery. An area...

From USFWS service description: "This data service identifies, in general, the areas where final critical habitat exist for species that are endangered or threatened. Special protections and/or restrictions are possible in areas where federal funding, permits, licenses, authorizations or actions occur or are required. Critical habitat are areas considered essential for the conservation of a listed species. These areas provide notice to the public and land managers the importance of these areas to the conservation of the species." The data can be downloaded in a shapefile, viewed on the Fish and Wildlife Service's map viewer, or accessed through a web service. It's also possible to view the data through the ScienceBase...

Critical habitat are areas considered essential for the conservation of a listed species. These areas provide notice to the public and land managers the importance of these areas to the conservation of this species. Special protections and/or restrictions are possible in areas where federal funding, permits, licenses, authorizations, or actions occur or are required.

Management of transportation networks is affected by, and has effects on, natural and cultural resources through direct and indirect interactions. Until recently, the availability of such spatially explicit information has been limited; however, the data released here to the public will prove valuable for comparing existing networks and planning options with respect to potential impact to, or from, environmental factors across broad areas, for example, States and Agency Planning Regions. Integrated network and resource analyses can provide insights into potential construction and maintenance costs as well as safety risks and environmental impacts during project planning and assessment. A cooperative project was...

This dataset was created to serves as one sub-layer of the Florida Marine Blueprint. The Florida Marine Blueprint was created to aid in prioritizing ecosystems and habitats derived from species biodiversity, highly valued habitat and potential marine migratory corridors. Highest priority areas are those where there is high species biodiversity/richness and overlaps in valued habitats. The Blueprint will then be used to inform where potential management and conservation practices should be focused and potentially carried out.

This USFWS data set has been modified by NatureServe to include critical habitat only within the Central Basin and Range, and Mojave Basin and Range ecoregions, and further modified to include only the desert tortoise (Gopherus agassizii). These data identify, in general, the areas where final critical habitat exist for species listed as endangered or threatened.

Critical habitats are areas considered critical to the survival of a particular species, as determined by USFWS. Ecoregions are areas of similar biota and climate, as determined by the EPA. This map was created by calculating the percent of each ecoregion that is considered critical habitat, regardless of species. The Critical Habitat by Ecoregion map was derived by calculating the percentage of each Ecoregion that is occupied by pixels representing Critical Habitat (of any species). The Critical habitats are areas considered critical to the survival of a particular species, as determined by USFWS. Ecoregions are areas of similar biota and climate, as determined by the EPA.

Federal Register Revised Designation of Critical Habitat for the Quino checkerspot butterfly (Euphydryas editha quino)
Erigeron kachinensis is a rare endemic of the Colorado Plateau in southeastern Utah. This perennial composite grows in small, isolated populations at seeps and alcoves arising along canyon walls in Cedar Mesa Sandstone substrates. Characteristics of six Erigeron kachinensis sites in Natural Bridges National Monument, San Juan County, Utah, were studied to determine habitat requirements for this species. Sites were analyzed with respect to geology, soil chemistry, physical properties, and vegetational characteristics. The alcoves studied were very saline, often with soil surfaces covered with a white crust of salt. Living cover was enhanced by perennially moist soils, diminished amounts of solar radiation, soil salinity,...

The California Coast has hundreds of tree groves where dual management practices aim to reduce the risk of fire and to conserve habitat for overwintering monarch butterflies. As the climate changes, longer high-intensity droughts can increase mortality and/or limb loss in grove trees which causes an accumulation of fire-prone fuels. Moreover, these trees provide the critical habitat for overwintering monarch butterflies. Every year only certain trees in certain groves accumulate clusters of thousands of monarch butterflies. Should trees die or important roosting branches collapse, monarchs may not return in the future. The overall goal of this project is to understand how the dual management goals of fire management...

The Great Plains Landscape Conservation Cooperative (GPLCC, https://www.fws.gov/science/catalog) is a partnership that provides applied science and decision support tools to assist natural resource managers conserve plants, fish and wildlife in the mid- and short-grass prairie of the southern Great Plains. It is part of a national network of public-private partnerships — known as Landscape Conservation Cooperatives (LCCs, http://www.fws.gov/science/shc/lcc.html) — that work collaboratively across jurisdictions and political boundaries to leverage resources and share science capacity. The Great Plains LCC identifies science priorities for the region and helps foster science that addresses these priorities to support...
