Conservation Trust Grant

The objective of the Conservation Trust is to support conservation activities around the world as they fit within the mission of the National Geographic Society. The trust will fund projects that contribute significantly to the preservation and sustainable use of the Earth's biological, cultural, and historical resources. The Conservation Trust's strength lies in supporting cutting edge programs that might be overlooked by other organizations, due to the risk involved in working with new investigators and in new fields.
