Colusa Basin Mitigation Bank Approved to Sell Giant Garter Snake Credits


June 22, 2014 — Colusa County, Calif.Colusa Basin Mitigation Bank (CBMB), an environmental project being developed by Westervelt Ecological Services, has been approved by state and federal natural resource agencies to restore Giant Garter snake (Thamnophis gigas) habitat and other wetlands on 160 acres in Colusa County. The first issue of credits is now available.

“We are excited about the approval of CBMB because it adds to a larger matrix of conservation projects supported by government, local, non-profit and private entities which are focused on the safeguard of this species and its habitats,” explained Greg Sutter, Executive Vice President of Westervelt Ecological Services. “Colusa National Wildlife Refuge is directly adjacent to CBMB and supports a well-documented population of Giant Garter snakes and provides functional habitat value and connectivity between CBMB and the nearby conserved lands.”

Most of the surrounding land use is either in rice production or managed as wetlands for migratory and resident species. Rice fields provide suitable habitat features for foraging Giant Garter snakes and expand the potential migration corridor between CBMB and habitats beyond the constraints of the channelized waterways.

CBMB is approved by the U.S. Army Corps of Engineers, the Environmental Protection Agency, the U.S. Fish and Wildlife Service and the California Department of Fish and Wildlife to provide mitigation credits to offset impacts to the Giant Garter snake and seasonal wetlands regulated under the Clean Water Act. The CBMBservice areas include portions of Tehama, Glenn, Butte, Colusa, Yolo, Yuba, Sacramento, Sutter, and Solano counties and will assist in fulfilling the species mitigation needs due to various development and infrastructure projects.

Owned by Westervelt Ecological Services, a private company, CBMB is protected in perpetuity by a conservation easement, funded by a non-wasting endowment, and managed to provide year-round habitat for Giant Garter snake and many other wetland-dependent species.
