The Center for International Forestry Research is a nonprofit, global facility dedicated to advancing human wellbeing, environmental conservation and equity. We conduct research that enables more informed and equitable decision making about the use and management of forests in less-developed countries.
a research and education organization interested in understanding the nature and extent of human interaction with the surface of the earth, and in finding new meanings in the intentional and incidental forms that we individually and collectively create. Neither an environmental group nor an industry affiliated organization, the work of the Center integrates the many approaches to land use—the many perspectives of the landscape—into a single vision that illustrates the common ground in “land use” debates.
The Center for Plant Conservation (CPC) is dedicated solely to preventing the extinction of U.S. native plants. The Center is a network of 39 leading botanic institutions. the Center operates the only coordinated national program of off-site (ex situ) conservation of rare plant material. This conservation collection ensures that material is available for restoration and recovery efforts for these species. CPC also works in research, restoration, technical assistance, education and advocacy through the efforts of the network and the national office.
