This page contains links to images of the Public Land Survey System for Wyoming. This information consists of images of all available survey plats for the entire state and approximately 30,000 pages of field notes. The plats are organized by county and then by township and range. The remaining 570,00 pages of field notes are in bound volumes and will not be available for quite some time. Additionally we have now posted all the available images for the Mineral and HES surveys.
This map layer consists of federally owned or administered lands of the United States, Puerto Rico, and the U.S. Virgin Islands. Only areas of 640 acres or more are included. There may be private inholdings within the boundaries of Federal lands in this map layer. This is a revised version of the December 2005 map layer.
This theme is polygon data that depicts two types of development for the state of Wyoming. The first is existing development and the second are habitats where there is a high likelihood that development will occur in the near future. We considered development of oil, gas and coal bed methane, mining of minerals (trona, uranimum, coal, and bentonite), urban expansion. Other infrastructure activities such as roads, highways, fiberoptic lines, processing plants, pipelines, other facilities, and various combinations of development that were believed to impact sage-grouse were recorded. Information sources and assessment processes varied depending on data available and resource specialist participation for areas within...
Tree size (quadratic mean diameter) for the Oregon Coast physiographic province of the Interagency Vegetation Mapping Project (IVMP)
This theme shows broadleaf cover for the Coast Oregon physiographic province of the Interagency Vegetation Mapping Project (IVMP). The Interagency Vegetation Mapping Project (IVMP) provides maps of existing vegetation, canopy cover, size, and cover type for the entire range of the Northern Spotted Owl using satellite imagery from the Landsat Thematic Mapper (TM). This area is commonly called the FEMAT area, in reference to the area's analysis by the Forest Ecosystem Management Assessment Team. A regression modeling approach was used to predict vegetation characteristics from this Landsat data. This process involved the use of numerous sources of ancillary data, the most crucial being USFS, BLM, and Forest Inventory...

BLM Resource Area Boundaries within the Western Oregon Plan Revision (WOPR) Proposed Resource Management Plan (PRMP) boundary. These resource area boundaries were modified along edges of the Western Oregon Plan Revision updated Analysis of Mangement Situatiion (AMS) project boundary and are intended for use in analytical summaries.BLM: (Bureau of Land Management) WOPR: (Western Oregon Plan Revision), POL: (Political) PRMP: (Proposed Resource Mangement Plan) AMS: (Analysis of Management Situation) RAB: (Resource Area Boundary) LUP: (Land Use Planning)
The mine permit boundary coverage was created for locational purposes and to aid counties in tax district assessment.
The northern leopard frog (Rana pipiens) is a formerly abundant frog that has experienced significant declines across its range and is considered endangered in some parts of the range but still abundant in other parts of the range. Various factors have been invoked to explain population declines in the northern leopard frog, including habitat destruction, diseases, chemical contamination, acidification, increased ultraviolet light due to loss of the ozone layer, introduced predators, overcollecting, climatic changes, and general environmental degradation. However, no one cause has emerged as the primary factor behind population declines in any area. Probably, multiple causes contribute to population...

These data describe areas of suitable habitat believed to be used (currently and historically) by wild, natural, and/or hatchery fish populations. The term "currently" is defined as within the past five reproductive cycles. See the 'USETYPE' field description to differentiate between current and historic distribution. This information is based on extensive surveys, the best professional judgment of ODFW staff biologists and where possible, the professional opinions of staff from other natural resource agencies. Due to natural variations in run size, water conditions, or other environmental factors, some areas displayed may not be used by a species of fish on an annual basis. The Natural Resources Information Management...
Hermit Warbler - VizBand/Land AIC Model Selection Created: 12-Aug-2011 Hermit Warbler annual capture rate of adult (ADULT) individuals (log transformed) ranged between -0.281 and +2.243 with a mean value of +0.981 and a median value of +0.875. ________________________________________ Model 1 (3 parameters) Hermit Warbler annual capture rate of adult (ADULT) individuals (log transformed) was a function of: a) GTOPO30_AL (+0.20641) - elevation (m), ranged between +5.119 and +8.376 (95% CL) with a mean value of +6.747 and a median value of +7.137, b) NLCD06AG5KP (-0.19572) - percent agricultural/grassland cover, 990m-resolution in a landscape context of 5km radius, ranged between -0.657 and +2.530 (95% CL) with a mean...
This file contains the polygon SDE Feature Class for Federal Fluid Minerals(Oil and Gas) for the Bureau of Land Management(BLM)Montana/Dakotas. Federal Fluid Minerals as well as Federal Lease status and Indian Minerals/Leases are included. Plat maps are used to find federal mineral ownership and the Bureau of Land Management's LR2000 database is used to find current leasing status.
Background information.—On July 8, 2012, lightning ignited a fire on Bureau of Land Management-managed land on the Miller Homestead in Harney County, Oregon. High winds combined with unusually hot and dry conditions spread the fire through dry grass and sagebrush and 160,801 acres were burned before the fire was contained on July 24, 2012. In the aftermath, it was determined that ecological restoration was necessary since the majority of the fire occurred within prime habitat for sage-grouse, and the fire had burned with such severity that it removed vegetation down to bare soil. Without rehabilitation efforts, desirable vegetation would be unlikely to reestablish and the site would be open to invasion by noxious...
USGS 1:1,000,000-Scale Federal Lands of the United States - Parkways and Scenic Rivers 201506 Shapefile
This map layer portrays the linear federally owned or administered land features (i.e., national parkways, wild and scenic rivers, etc.) of the United States and Puerto Rico. Some features may be administered in conjunction with local governments. The map layer was created by extracting and combining linear federal land features from the 1:1,000,000-scale Roads and Streams files that are part of The National Map. There are no Parkways or Scenic Rivers in Hawaii or in the U.S. Virgin Islands.
Areas of Critical Environmental Concern (ACECs), Research Natural Areas (RNAs), and Outstanding Natural Areas (ONAs) of Idaho
ACECs are areas where special management is needed to protect important historical, cultural, or scenic values, fish and wildlife resources, or other natural systems or processes, or to identify areas hazardous to human life and property. Criteria for ACECs can be found at: BLM Manual 1613 and 43 CFR 1610.7-2(b). RNAs are areas where natural processes are allowed to predominate and which is preserved for the primary purposes of research and education. Under current BLM policy, RNAs must meet the relevance and importance criteria of ACECs and are designated as ACECs. Criteria for RNAs can be found at: BLM Manual 1613 and 43 CFR 1610.7-2(b). ONAs are areas with high scenic values that have been little altered by human...
The public ownership layer shows land ownership/management for public entities, Federal, Tribal, State, and Local. The base linework was derived mostly from the BLM Landlines (Public Land Survey & Jurisdiction) layer and from ODF ownership layer. This base linework was enhanced using lines derived from the Government Corners Database (GCDB)
