The Conservation Needs Assessment (CNA) for Papua New Guinea was requested by the government of Papua New Guinea and funded by the U.S. Agency for International Development (USAID). The CNA was implemented by the Biodiversity Support Program, a USAID-funded consortium of World Wildlife Fund, World Resources Institute, and The Nature Conservancy, in collaboration with
local and international nongovernmental organizations (NGOs), museums, and academic institutions.
The assessment compiled an extensive body of the available scientific literature on the biological diversity (biodiversity) of Papua New Guinea and assessed the present state of knowledge, conditions, trends, and environmental threats. Special maps were produced identifying sites of particularly high endemism, high species richness, and unusual ecosystems and habitats.
