The Maya Forest
Also known as the Selva Maya, is the largest remaining tropical rainforest in Mesoamerica and the second-largest in the Americas after the Amazon. Spanning approximately 15 million hectares (about 37 million acres), it covers much of the Yucatán Peninsula, including southeastern Mexico, northern Guatemala, and all of Belize. This vast ecosystem is a biodiversity hotspot, a cultural cradle for indigenous Maya communities, and home to ancient archaeological sites, but it faces significant threats from deforestation and climate change.
Geography and Formation
The Maya Forest is a tropical moist broadleaf forest that emerged around 20,000 years ago after the Last Glacial Maximum. It stretches across diverse terrains, from the evergreen forests of Guatemala’s Petén region to drier woodlands in northern Yucatán.
The region features over 20 distinct ecosystems, including mangroves, wetlands, and karst landscapes with underground rivers and cenotes (natural sinkholes). It forms the northernmost part of the Mesoamerican Biological Corridor, connecting habitats across Central America. Key protected areas include the Maya Biosphere Reserve in Guatemala (over 2 million hectares) and the Río Bravo Conservation Area in Belize.
Biodiversity
This forest teems with life, hosting over 4,000 plant species, 400 bird species, and 100 mammal species.
Iconic wildlife includes:
- Jaguars: One of the healthiest populations in Central America.
- Endangered species: Tapirs, scarlet macaws, harpy eagles, white-lipped peccaries, Yucatán black howler monkeys, and Central American river turtles.
- Flora: Dominant trees like mahogany, ceiba (the “world tree” in Maya cosmology), and ramón provide food, medicine, and habitat.
The forest’s richness supports ecosystem services like water regulation for millions and carbon sequestration, helping mitigate climate change.
Human History and Cultural Significance
The Maya Forest has been shaped by human hands for millennia. Paleoindigenous hunter-gatherers arrived around 13,000 years ago, followed by the ancient Maya civilization (c. 2000 BCE–1500 CE), whose cities like Tikal, Calakmul, and Palenque dotted the landscape. Contrary to early myths of a “pristine” wilderness, the Maya actively managed the forest through “forest gardens”—unplowed, tree-dominated plots integrated into the milpa cycle (slash-and-burn agriculture followed by fallow periods). These gardens, still practiced by modern Maya, nurture useful plants for food, fiber, and medicine while preserving biodiversity.
Today, about 600,000 people live around the forest’s edges, including indigenous Maya and Afro-descendant communities who steward it as sacred land. Archaeological treasures, such as Guatemala’s Yaxhá and Belize’s La Milpa, highlight its role as the heart of Maya culture.

Conservation Efforts
Conservation is a priority, blending indigenous knowledge with international partnerships. In August 2025, Mexico, Guatemala, and Belize signed a historic agreement creating the Biocultural Corridor of the Great Mayan Forest (CBGSM), a 5.7-million-hectare trinational reserve, the largest protected area in the Americas after the Amazon. This initiative emphasizes indigenous guardianship, shared fire management, anti-logging strategies, and sustainable resource use.
Other efforts include:
- The Nature Conservancy (TNC): promoting green economies to replace destructive ranching and agriculture.
- Wildlife Conservation Society (WCS): training rangers in wildfire suppression, as seen in a September 2025 program in Belize’s Maya Forest Corridor.
- Community mapping: in Guatemala’s San José Poaquil, Kaqchikel Maya youth use open-source tools to monitor threats like illegal logging, securing land titles and ecosystem payments since 2016.
- Global Conservation: protecting key tracts like the Greater Belize Maya Forest to link habitats and prevent conversion to industrial farms.
These programs aim to transform the region from a “deforestation hotspot” into a model of sustainable coexistence.
Threats and Challenges
Despite progress, the Maya Forest is shrinking. Satellite data from 2000–2023 shows significant loss, up to 10% in parts of the Maya Biosphere Reserve.
This loss has been mainly driven by:
- Agriculture and ranching: Expansion of cattle pastures and soy fields, often replacing traditional methods.
- Illegal activities: Logging, wildlife trafficking, and narco-trafficking clearings.
- Fires and climate change: Increasing wildfires, exacerbated by droughts.
Guatemala, in particular, saw record deforestation in 2023, with risks persisting into 2025. Without scaled-up action, the forest could lose another 20% by 2050, threatening species, water supplies, and cultural heritage.
Why It Matters
The Maya Forest isn’t just an ecological treasure, it’s a living testament to human resilience and harmony with nature. Protecting it ensures biodiversity, combats climate change, and honors indigenous stewardship.
Visitors can explore via eco-tourism in sites like Belize’s Maya Mountains or Guatemala’s protected reserves, but sustainable practices are key to its future. For more resources, the Selva Maya Initiative offers updates on ongoing work.
Protecting these bioregions is essential!
Protecting the forest, the reef and the water systems is essential for preserving the delicate balance of life, maintaining cultural heritage, and ensuring the health and prosperity of the indigenous peoples who have lived in harmony with these waters for generations.
United, we can safeguard these vital bioregions, a source of life and heritage for all.
Not only for their biodiversity but also for maintaining the delicate balance of our global ecosystem and honoring the indigenous cultures that have thrived here for millennia.
