The Calakmul Conservation Fund makes payments for environmental services to three communities (ejidos) in the Calakmul Biosphere Reserve (Pustunich, Yohaltún, and the Om Lagoon) in charge of forest conservation. Since 2021, they have been receiving support from Amigos de Calakmul, A.C. (Friends of Calakmul, a non-profit organization) and the payments are channeled through the Mexican Forestry Fund held by the National Forestry Commission. This collaboration implies pooling public resources and delivering them directly to the communities in a single deposit.
