The Herd Management Area coverage is polygon coverage of Wild horse and Burro use areas. A "Herd Area" is defined by the "Wild and Free-Roaming Horse and Burro Program Guidance, January 1983" as "The geographic area identified as having been used by a herd as its yearlong habitat in 1971" and a Herd Management Area" is defined as "A herd area identified in an approved land use plan where wild horses and burros will be maintain and managed.", boundaries and attributes were gathered from various maps and reports.
This data was merged into the National Data set in 2004, and then extracted for maintenance in 2005. Herd Management Areas extended onto USFS Herd Territories were pulled during the National merge with National, and other minor boundary adjustments were made for unknown reasons. The California Data has been reviewed and updated (name changes and PLSS allignment) in 2006.

The data is intended to be used for display and analysis of Herd Management Areas.
raw data, attributes
Data taken from historical records was drawn onto 1:24000 Quadrangle maps then digitized on a digitizing tablet. The 1:24000 digitized quads were then merged into an Area Wide coverage.
Created by dborghi using FGDCMETA.AML version 1.2 05/14/98 with CA BLM Template on ARC/INFO Coverage /gis/master/basic/range_mgmt/hmapsra

Integrated National Data Set. Herd Management Areas that extended onto USFS Herd Territories were pulled. Other chnages were made, the justification for which are largely unknown, but in many cases appear to have been coordinated with the local Field Offices..
National Data Set cut to California Extent for Maintenance
CA Field Office Review. One Name change, and vertically integrated with PLSS
Attribute data was test by manual comparison of the sources data with symbolized display of the map data on an interactive computer graphic system. Data was also verified by natural resource staff familiar with the Wildhorse and Burro Program.
Coverage is based on data drawn on 1:24000 quadrangles and digitized on a tablet. The digitized maps were registered to .004 RMS or less, the accuracy of the hand drawn maps is unknown and the accuracy of the digitized data is untested. The data was review by resource area staff and accuracy was determined to be reasonable.
Polygon topology present.
