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.

Lands within the watersheds of the Great Plains streams that are not used for crops are often used for cattle grazing and hay production. Northern Plains States are one of the nation’s top producers of cattle, which outnumber people almost three to one in North Dakota. Cattle can have direct habitat impacts by trampling stream banks, which destroys beneficial vegetation and increases sedimentation and nutrient loads. Hofmann and Ries (1991) found that livestock increased sediment runoff in North Dakota streams. Schepers and Francis (1982) reported that runoff from a Nebraska cattle farm increased total phosphorus levels in runoff by 37%. In addition, cattle watering ponds, often constructed by diverting streams,...

A consolidated grazing dataset representing BLM and FS submissions, with ownership indicated in the 'Mngmnt' field. Overlaps are identified as "BLMFS". BLM - GSSP allotments and pastures merged, overlaps removed, and dissolved to one polygon. GSSP SNAPSHOT of Approved data set made on 5/14/12 for the Greater Sage-grouse baseline rangewide cumulative effects analysis. This aggregate national dataset identifies allotments within BLM managed public lands. FS - This allotment layer is a merged and dissolved representation of the 27 allotment data files submitted to the BLM by the USFS for the GRSG CEA. As needed, records with ‘Unit_Type’ = 1 were selected for the merge, while the remainder were omitted. Additionally,...
