The Sophie Danforth Conservation Biology Fund (SDCBF), established by Roger Williams Park Zoo and the Rhode Island Zoological Society in 1989, supports conservation programs that protect threatened wildlife and habitats worldwide. Field studies and other projects that demonstrate a multi-disciplinary approach to biodiversity and ecosystem conservation, and projects that involve in-country collaborators receive the highest funding priority. Environmental education programs, development of techniques that can be used in a natural environment, and captive propagation programs that stress an integrative approach to conservation are also appropriate. Projects must directly affect biological conservation.
