Conservation credits include species credits as well as non-wetland habitat credits in states such as California. Conservation credits help achieve no net loss for rare biodiversity resources listed under state and federal Endangered Species Acts. When human activities impact biodiversity resources, purchase of conservation credits helps protect, enhance, restore or sometimes create habitat supporting the impacted species in similar nearby ecosystems.
Species credits, also called ‘Endangered Species Recovery Credits’, are described as ‘conservation credits that can be used at a later time to offset negative impacts’ of agency-approved actions. U.S. Fish & Wildlife Service implements this program under the Endangered Species Act as ‘a net benefit to the conservation of federally protected species (offering) incentives for federal agencies to reach out to private landowners and conserve imperiled wildlife.’
