April 5, 2021 (LOS ANGELES) – The City of Los Angeles Department of Water and Power (LADWP) today announced the completion of the Long Valley Adaptive Management Plan (Plan) for Bi-state sage-grouse. Developed in partnership with the United States Fish and Wildlife Service (USFWS), the Plan’s completion reaffirms LADWP’s commitment to protecting nearly 40,000 acres of sage-grouse habitat in Mono County.
The Bi-state sage-grouse is a distinct population segment (DPS) of the Greater sage-grouse (Centrocercus urophasianus) found in Owens Valley, California and western Nevada. The Bi-state sage-grouse is not listed as threatened or endangered under the California State or Federal Endangered Species Acts, but the DPS has been evaluated for listing multiple times and sage-grouse continues to be a species of concern for private, local, state and federal partners across the Eastern Sierra.
Portions of LADWP-owned lands in Mono County (Long Valley) have provided historic and important habitat for this species and this encouraged LADWP and USFWS to develop conservation strategies that can be implemented on LADWP property. The Plan was collaboratively developed with input from other regulatory agencies and sage-grouse experts and is intended to be a living document to guide land management decisions that will ultimately preserve and enhance the Bi-state sage-grouse population. In addition, the Plan follows the collaborative 2014 Conservation Strategy that includes commitments to maintain sage-grouse breeding grounds (leks) and nesting and brood rearing habitat across 38,389 acres of LADWP-owned property within the Bodie Hills and South Mono population management areas.
“The key to successful projects is working together with like-minded partners like the U.S. Fish and Wildlife,” said LADWP General Manager and Chief Engineer Martin L. Adams. “LADWP has a long history of development and implementation of projects to sustain and enhance biodiversity on the lands it manages in the Owens Valley and Eastern Sierra and remains steadfast in its continued commitment to environmental stewardship.”
The overall goal of the Plan is to achieve the highest quality habitat conditions for the sage-grouse within LADWP’s operational capacity and with the most efficient allocation of water. Specifically, the Plan provides an approach to better identify objectives for managing mesic (wet, green), brood-rearing habitat in pastures that have historically been altered by supplemental irrigation. LADWP biological resource staff will help determine conservation activities by preparing an annual monitoring report about water availability and distribution for the year, as well as the habitat quality results.
“Employing this Adaptive Management Plan for the sage-grouse allows us, as regional partners, to be nimble and continually update management practices to meet new challenges,” Said Richard Harasick, LADWP Senior Assistant General Manager of Water System. “We are encouraged by this collaborative effort and are confident that we are taking steps in the right direction to help protect existing resources and enhance the region’s unique ecology.”
LADWP is proud to work with other interested groups to ensure the best outcome for the sage-grouse. To help develop the Plan, LADWP and the USFWS established a technical working group and invited the following stakeholders to participate: Audubon Society, local ranchers, Bureau of Land Management – Bishop Office, Inyo National Forest, U.S. Geological Survey, California Department of Fish and Wildlife, and Mono County.
LADWP also continues to focus efforts on ongoing monitoring and maintenance such as adopting specialized grazing plans to reduce interference with sage-grouse and minimizing recreational impacts through public education signage, barriers, and dedicated walkways. It continues the enforcement of a Sage-Grouse Viewing and Access policy on its lands, which includes seasonal closures during peak breeding periods.
Since the early 1990s, LADWP has focused on natural resource projects that restore riparian vegetation along the Owens River, Mono Basin and tributaries. In addition to water quality and water quantity benefits from these projects, plant and animal biodiversity has increased, fish and wildlife populations have increased, and there are more acres of wetlands in the watershed than in decades past.
