Instruction Memorandum No. 2006-149
To: All Field Officials
Subject: Livestock Grazing Allotment and Pasture Spatial Database Standards
Program Area: Rangeland Management
Purpose: The purpose of this Memorandum is to transmit the Bureau of Land Management’s data standards for mapping and recording grazing allotment and pasture boundaries.
Policy/Action: The data standards for developing and maintaining livestock grazing allotment and pasture boundaries in electronic format are found in Attachments 1 and 2 of this Instruction Memorandum. All offices are to use these standards when developing, amending, or maintaining electronic allotment and pasture boundary maps.
Background: Beginning in 2001, BLM allocated range program funds to each of the states to digitize allotment boundaries, and directed that these be submitted to National Science and Technology Center (NSTC) for a national level spatial database. The intent was to reduce the number of data calls and to have publicly accessible maps of grazing allotments. Development of the Range Administration System (RAS) was occurring at the same time, and BLM recognized that a link between RAS and allotment maps made available on National Integrated Land System (NILS) could further reduce data calls to field offices, and make public information available to the public. In 2003 and 2004, two Freedom of Information Act (FOIA) requests were submitted to the Washington Office requesting amongst other things, maps of allotments. At that time, not all states had provided the allotment maps to NSTC. Consequently, in response to the FOIA request, Washington Office asked each state to provide an electronic copy of allotment maps. The maps received had been developed without a consistent set of data standards, so some inconsistencies were identified during the response to the FOIA requests. A team with representatives from field offices, State offices, Washington Office, and NSTC was tasked with developing a set of standards and a national allotment map using the information that the States provided in response to the FOIA requests. These standards are now being presented to all field offices and are to be used to develop, maintain, or amend electronic maps of allotment and pasture boundaries.
Time Frame: Effective immediately.
Budget Impact: None
Manual/Handbook Sections Affected: None
Coordination: Development of these standards was coordinated amongst WO-220, WO-210, representative state range program leads and GIS coordinators.
