The Biodiversity Support Program (BSP) operated from 1989-2001 as a consortium of World Wildlife Fund (WWF), The Nature Conservancy (TNC), and World Resources Institute (WRI) and was funded by the United States Agency for International Development (USAID).

BSP's mission was to promote conservation of the world's biological diversity believing that a healthy and secure living resource base is essential to meet the needs and aspirations of future generations.

BSP carried out its mission by supporting projects that combined conservation with social and economic development. Specifically it undertook:

BSP worked with many partners, including nongovernmental organizations, governments, communities, donors, academics, and the private sector.

In addition to the regional programs, BSP instituted a cross-cutting Analysis and Adaptive Management (AAM) Program to analyze five thematic approaches to conservation and to focus attention on lessons learned across regional programs.

During its thirteen years, BSP learned many lessons about different approaches to biodiversity conservation and developed many concepts and tools. These have been documented in BSP's library of publications for conservation practitioners and decision-makers around the world.

BSP worked closely with USAID, enhancing access to current developments in biodiversity conservation and helping USAID to maximize the impact of U.S. government resources directed toward international biodiversity conservation.

Initially, BSP was established as a five-year program with $12.8 million in funding through a cooperative agreement with USAID. Ultimately, BSP received funding from three cooperative agreements with USAID as well as fund transfers from USAID Missions and Regional Bureaus interested in participating in the program. BSP's total budget reached $85 million.
