Mexico, Guatemala and Belize create a tri-national reserve for the Maya forest

# Mexico, Guatemala and Belize create a tri-national reserve for the Maya forest

The conservation area would cover more than 14 million acres and rank among Latin America’s biggest protected landscapes.

The leaders of Mexico, Guatemala and Belize have announced a tri-national nature reserve aimed at protecting the Mayan rain forest, a project that immediately stands out for both scale and symbolism. According to AP, the reserve would stretch across jungled areas of southern Mexico and northern parts of Guatemala and Belize, covering more than 14 million acres, or 5.7 million hectares. Mexican President Claudia Sheinbaum called the move historic and said it would become the second-biggest nature reserve in Latin America, behind the Amazon rain forest.

That size matters because conservation often fails when protected areas are too fragmented to matter ecologically. A reserve crossing three countries suggests a different ambition: preserve habitat at a landscape level, rather than treating forests as isolated patches. AP’s reporting says the leaders gathered in Calakmul, in Mexico’s Campeche state, and presented the reserve as a joint answer to a shared ecological problem. Sheinbaum’s description of the region as one of Earth’s lungs was more than rhetoric; it was a signal that the governments want the site treated as globally important.

The announcement also comes with a cautionary note from environmental groups. AP says Mexico-based Selvame welcomed the move as a monumental step for conservation, but warned that it must be more than symbolic. The group pointed to real estate and construction companies invading the jungle, polluting ecosystems and threatening the water and communities that depend on it. That warning matters because protected status on paper does not automatically prevent illegal clearing, bad projects or incremental damage at the edges of a reserve.

The meeting was not only about the reserve. The leaders also discussed a Mexican proposal to expand the Maya Train line from southern Mexico to Guatemala, despite years of criticism that the project has cut through jungle habitat. That is the tension at the heart of the story. The same political leaders who are promising stronger conservation are also debating infrastructure that critics say could deepen ecological harm if it is not designed and monitored carefully.

For Sheinbaum, Bernardo Arévalo and Johnny Briceño, the reserve announcement offers a rare diplomatic storyline built around cooperation rather than dispute. A cross-border protected area requires coordination on enforcement, land use and monitoring, which means the declaration only matters if the governments follow through. AP’s coverage makes clear that environmental groups are watching closely, precisely because the reserve will be judged by what happens on the ground rather than by the press conference itself.

The broader significance is hard to miss. Conservation efforts often get framed as local policy, but the Maya forest is a regional ecosystem with cultural, economic and climatic value that no single government can manage alone. By moving together, the three countries are acknowledging that reality. The reserve could become a model for transnational habitat protection if it is enforced well, or another example of a grand announcement that fails to keep pace with development pressure. The difference will come down to implementation.

For now, the evidence supports a clear conclusion: the three governments have made a big conservation promise, and they did so with a reserve large enough to matter on a continental scale. The scale is historic, the environmental stakes are high, and the next phase will be less about words than about whether the jungle is actually protected from the pressures already moving toward it.
