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.
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...
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.

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...
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...

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)
