Mitigation Projects

Antelope Valley Conservation Bank

Wildlands has proposed the Antelope Valley Conservation Bank located in the northern portion of the Antelope Valley in Kern County to permanently protect a population of western Joshua tree (Yucca brevifolia) and its habitat. The proposed Bank is currently under review by the California Department of Fish and Wildlife (CDFW). On September 22, 2020, the California Fish and Game Commission determined that listing western Joshua tree as threatened or endangered under the California Endangered Species Act may be warranted, commencing a one-year status review of the species.

In addition to providing Joshua tree mitigation, the proposed Bank will also provide offsite compensatory mitigation for stream habitat and may potentially serve as mitigation for other special-status species, as warranted. Establishment of the Bank will permanently protect a biologically rich area with approximately 21,000 western Joshua trees and nearly 10 acres of stream habitat.

700 acres

Location: Kern County, California

Mitigation Types

  • Joshua Tree
  • Waters of the State

Service Area


The proposed service area boundary is in development. The Joshua tree service area will take into consideration the distribution of western Joshua tree as well as the Bank’s location within the Western Mojave Desert Tortoise Recovery Unit; currently, the proposed service area includes the California portion of the Western Mojave Desert Tortoise Recovery Unit as well as any areas within California of the YUBR South and YUBR North populations that fall outside of the Recovery Unit.

The proposed stream credit service area includes the entirety of the Antelope HU, extending to the east to include the adjacent Mojave HU, extending northerly within the jurisdictional limits of the Lahontan Regional Water Quality Control Board (LRWQCB) to the County lines (i.e. to Kern and San Bernardino Counties’ northern boundaries).
