Grazing Allotments Data Standard Version 4.0

This information bulletin announces the availability and description of recent updates to the Grazing Allotments Data Standard Version 4.

This dataset contains livestock grazing allotment and pasture boundaries with associated attributes describing some basic characteristics of the allotments and pastures. Allotments are made up of pastures. The dataset contains pasture boundary polygons, GRA_POLY, and its coincident line pair, GRA_ARC, which contains boundary definition information. The BLM allotments are tied to the 1934 Taylor Grazing Act that set up grazing districts.

This dataset is used for depicting grazing allotments and pastures on maps. Pasture boundaries are dissolved to form allotment boundaries. The grazing allotment and pasture dataset is one of the most important datasets to BLM business, and it is also used in most National Environmental Policy Act planning, and other resource analysis. Resource specialists involved in administration of livestock grazing programs use this dataset.

The following changes were applied:

• Reformatted document to meet Section 508 standards and match the latest data standard template.
• Updated FOIA category, records retention schedule text, and keywords.
