In most cases, preservation or restoration of an area of an ecosystem is a joint effort among government, organizations, and individuals. Nearly always, the most important forces for conservation are the communities and indigenous peoples and the governments (local, regional, and/or national) hosting the ecosystem. And the most important non-governmental organizations and individuals involved are nearly always those that are local to the area of the ecosystem.
However, non-governmental organizations in many locations often provide key supporting roles, as do others providing financial support to such organizations. And multiple such organizations may provide support of a single area of ecosystem.
Multiple parties, including many not specifically recognized by MAP, therefore share credit for conservation of a particular area.
