Engage landowners and other volunteers to manage land for amphibians Amphibian Conservation

A study in 2010 of landowner agreements to manage habitats for amphibians in California, USA (Kuyper 2011) found that eight ranchers and a Municipal Utility District enrolled in 30-year agreements. The eight ranchers managed over 4,000 ha and the Municipal Utility District 8,000 ha of habitat for two amphibians of conservation concern, the California red-legged frog Rana draytonii and the California tiger salamander Ambystoma californiense. Data were not provided to determine the effect on target species. Agreements were made between the US Fish and Wildlife Service and private landowners, with landowners agreeing to carry out management activities for the benefit of priority conservation species. Management included maintenance of stock ponds and surrounding uplands and bullfrog and fish removal. At the end of the agreement landowners were authorized to cease management and return their property to its original condition.
