National Bulletin: 190-21-3 Date: November 16, 2020
Subject: ECS - Interpreting Indicators of Rangeland Health, Version 5

Purpose.   To announce the release of “Interpreting Indicators of Rangeland Health,” Version 5.   
Expiration Date.   September 30, 2021
Background.   “Interpreting Indicators of Rangeland Health,” Version 5, also referred to as Technical Reference 1734–6, dated August 15, 2020 was recently released. Version 5 is the third published edition and is an update of Version 4, dated August 15, 2005.

Completion of this technical reference was a collaborative effort through an Interagency Rangeland Health Team with representatives from the Department of the Interior, Bureau of Land Management (BLM), the U.S. Geological Survey, and the Department of Agriculture, Agricultural Research Service, U.S. Forest Service and NRCS.

Planners collecting rangeland field data are expected to use this updated version for their rangeland health assessments. Training on Interpreting Indicators of Range Health is available through NRCS-NEDC Course 000155.

Explanation.   “Interpreting Indicators of Rangeland Health,” Version 5, provides planners with the tools to do a preliminary evaluation of soil/site stability, hydrologic function, and integrity of the biotic community on rangelands. This document is accessible through the NRCS Grazing Lands Web site at https://www.nrcs.usda.gov/wps/portal/nrcs/main/national/landuse/rangepasture/range/. A National Instruction (NI) will follow this NB further explaining the differences between versions 4 and 5, including consistency of protocol use.

The National Range and Grazing Lands Specialists at the National Technology Support Centers will be distributing a limited supply of printed copies to selected NRCS State offices to states that collect rangeland data and have rangeland as a land use. This delivery is coordinated with the BLM Printed Material Distribution Service, Gene Fults at the WNTSC, and the State Range Management Specialists. Shipping cost will be paid for through the WNTSC.

If additional copies are needed by the States, the BLM has printed copies available for ordering at $7.00 per copy plus shipping. To place an order, contact BLM by e-mail at BLM_NCS_PMDS@blm.gov, by facsimile at (303) 236-0845, or through regular mail at BLM National Business Center, Printed Material Distribution Service, BC-652, P.O.
