Conservation Capital

OSI's Conservation Capital program seeks to accelerate the rate and effectiveness of conservation by providing grants and short-term, low-cost bridge loans for land transactions in selected landscapes in the eastern United States. OSI helps projects that enhance existing conservation lands, help to channel or redirect development away from sensitive natural areas or that will protect open spaces under immediate threat of being developed.

To be successful, the land conservation movement needs tools and strategies in order to protect critical open spaces. OSI's research brings practical solutions to the land use challenges facing practitioners, funders and policy-makers in the 21st century.
