Subject:Assistance to the Natural Resources Conservation Service (NRCS) for the 2023 Rangeland Resource Assessment on Public Lands in California and NW Nevada
Program Area:L1020 Rangeland Management; L1050 Cultural Resources Management; L1060 Wild Horses and Burros; L1160 Aquatic Habitat Management; L1170 Wildlife Habitat Management; L1210 Wilderness Management; L1711 National Monument and National Landscape Conservation
Purpose:

This Instruction Memorandum provides guidance regarding Bureau of Land Management (BLM) assistance to the Natural Resources Conservation Service (NRCS) for the purpose of collecting data from rangelands administered by the BLM in California and northwest Nevada.

Administrative or Mission Related:

Mission-Related

Policy/Action:

While conducting the 2023 NRCS Rangeland Resources Assessment as part of the National Resource Inventory (NRI), the NRCS may wish to dig soil pits or other smallscale ground disturbances on BLM lands. On average, a ground disturbance measures 20 inches deep and 12 inches in diameter. Depending on the actual size of the ground disturbance and the direction of the assigned Cultural Resource Specialist in each Field Office, Protocol Exemption 1A may apply to some, none, or all of these locations.

Table 1 presents the breakout by Field Office and county for the number of randomly selected locations on BLM public lands for NRI assessment.  The table provides a first approximation of workload for Field Offices in 2023. The CASO will provide exact locations to each Field Office once NRCS finalizes selection.

GIS assistance may be required to open the zipped files when you receive the locations. NRCS will provide further details about its data collection activities on BLM-managed lands, after its review to eliminate any site locations that do not meet NRI rangeland definitions or are deemed inaccessible due to slope, distance from roads, etc.

The NRCS may request your assistance to:

  • Review site locations to confirm that assessment locations are on BLM-administered lands.
  • Ensure that the NRCS can access those sites through any locked gates or other barriers.
  • Identify sites that have no access.
  • Identify sites with military contamination or hazard.
  • Provide guidance to NRCS on best methods to access sites in Wilderness Areas and Wilderness Study Areas (WSAs) to assure preservation of wilderness character.
  • Ensure compliance for protection of cultural resources and special-status plant and wildlife species.

The NRCS staff and partners understand that they must not use motorized and mechanical vehicles or equipment in Wilderness Areas and WSAs.

The NRCS will report findings periodically to the BLM before publication of the national final annual report. Fieldwork for the inventory is scheduled for early March 2023. A representative from the NRCS NRI will be contacting each Field Office in advance of field work for advice on logistics.

Timeframe:

Policy and associated actions become effective on the date of the signature of the State Director

Budget Impact:

No additional costs. Funding for BLM staff to assist the NRCS with its data collection is part of base programs for each Field Office.

Background:

The Rural Development Act of 1972, the Soil and Water Resources Conservation Act of 1977, and other supporting legislation mandate the NRCS to assess the condition and trends of soil, water, and related resources on the Nation’s non-federal lands using the National Resources Inventory (NRI). Since 2011, the NRCS NRI has conducted the Rangeland Resource Assessment on lands managed by the BLM as well. The BLM National Office has reviewed and approved the NRI on BLM lands and has authorized its continuance for an additional three years. The NRCS jointly conducts the Rangeland Resource Assessment with the Iowa State University Center for Survey Statistics and Methodology.

Manual/Handbook Sections Affected:

None.
