Mitigation Projects

Antelope Valley Conservation Bank

Wildlands has established 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 Bank is approved 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. The western Joshua tree is currently protected as a candidate for listing.

In addition to providing Joshua tree mitigation, the Bank also provides offsite compensatory mitigation for stream habitat and may potentially serve as mitigation for other special-status species, as warranted. Establishment of the Bank permanently protects a biologically rich area with approximately 21,000 western Joshua trees and nearly 10 acres of stream habitat. A Bank expansion currently underway adds 320 acres with over 30,000 more western Joshua trees proposed for permanent protection.

Service Area


The Joshua tree service area boundary is based on the distribution of western Joshua tree as well as the Bank’s location within the Western Mojave Desert Tortoise Recovery Unit; the 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 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).
