The Maya Biosphere Reserve is a nature reserve in Guatemala managed by Guatemala's National Council of Protected Areas. The Maya Biosphere Reserve covers an area of 21,602 km², one-fifth of the country's total land area.
The park is home to a large number of species of fauna including Morelet's crocodile and the ocellated turkey. It is also rich in flora including breadnut, mahogany, Swietenia humilis, Bloma prisca, Vitex gaumeri, cedar, Bucida buceras, Haematoxylum campechianum, Rhizophora mangle, and Pimenta dioica. The area ranges from wetlands, to low mountain ranges, and has several bodies of water, including lakes, rivers, streams and cenotes.
The Reserve was created in 1990 to protect the largest area of American tropical forest remaining north of the Amazon. The biosphere reserve model, implemented by UNESCO, seeks to promote a balance between human activities and the biosphere by including sustainable economic development in conservation planning.
