Mitigation Projects

Lytle Creek Conservation Bank

The Lytle Creek Conservation Bank offers habitat mitigation credits to compensate for unavoidable impacts to San Bernardino kangaroo rat (Dipodomys merriami parvus) (“SBKR”) and Santa Ana River woollystar (Eriastrum densifolium ssp. sanctorum) (“SARW”) within the Bank's approved service area. The Bank is located in unincorporated San Bernardino County, California near the City of Rialto in the alluvial floodplain and active channel of Lytle Creek, just downstream from the confluence of Lytle and Cajon Creeks. The entire Bank is located within an area designated by the U.S. Fish and Wildlife Service as Critical Habitat for the SBKR. Lytle Creek is a tributary to the Santa Ana River, which is identified as important potential habitat for the SARW.

Covered Mitigation Types:

  • San Bernardino Kangaroo Rat (Dipodomys merriami parvus) is a federally endangered species and California Species of Special Concern. SBKR are a small, nocturnal, four toed sub-species of the Merriam’s kangaroo rat and native to the sand and gravel alluvial washes of southern California. SBKR is most often found foraging on seeds, green plants, and insects in sage brush complexes. SBKR have been documented as present at the Bank.
  • Santa Ana River Woollystar (Eriastrum densifolium ssp. sanctorum) is a Federal and State listed endangered shrub. SARW is native to the alluvial bars of the Santa Ana River and its tributaries. It can grow to be about a meter tall, has grey-green stems with bright blue flowers arranged in clusters of about 20 flowers each. There are documented occurrences of this species throughout the Bank.
  • Riversidian Alluvial Fan Sage Scrub habitat is a rare habitat type found in deposited alluvium adjacent to active channels in Southern California. The Bank provides protection for RAFSS and the active channel of Lytle Creek. RAFFS mitigation credits can be purchased from the Bank on a case by case basis with the approval of the natural resource agencies.
