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.
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...
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...
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.

The Institute for Bird Populations (IBP) coordinates the Monitoring Avian Productivity and Survivorship (MAPS) Program to assess and monitor the vital rates and population dynamics of North American landbirds. The MAPS Program utilizes a standardized constant-effort mist netting and banding protocol (DeSante et al. 2010) at a continent-wide network of monitoring stations. Each summer dedicated volunteers operate bird-banding stations to collect data on individual "birds-in-the-hand" representing over 200 species. Analyses of MAPS data provide critical information relating to the ecology, conservation, and management of North American landbird populations and the factors responsible for changes in their populations....

This dataset shows the potential wood contribution to fish bearing streams for the Western Oregon Plan Revision (WOPR). The potential wood contribution is determnined for all streams over entire channel networks, including wood recruitment processes for channel-adjacent tree fall, mass wasting and channel migration. Model inputs are 10 meter Digital Elevation Models (DEM) and forest cover with detailed forest stand tables specifiying stem density,size and mortality rates for each size class in each stand type.BLM (Bureau of Land Management) WOPR (Western Oregon Plan Revision) PRMP (Proposed Resource Managment Plan) Channel locations and geomorphic attributes extraced using algorithms described in Clarke, S.

This is an aggregate dataset for the DRECP 12 km buffer region, depicting the geographic boundaries of Grazing Allotments within BLM managed public lands. An allotment is an area of land designated and managed for grazing of livestock (43 CFR 4100.0-5). An allotment may include private, state, and public lands under the jurisdiction of the Bureau of Land Management and/or other federal agencies. An allotment may be subdivided into pastures. Range improvement projects are not depicted within this dataset.

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...
