The extension of the IBA Maya-Lacandon is almost identical to the Maya Biosphere Reserve, which covers the northern part of the province Peten, equaling 19% of the country. This area forms together with forests in Belize and the Mexican states of Campeche and Quintana Roo the largest Neotropical forest north of the Amazon basin. It is an important continental stronghold for species requiring large forested areas.
More than 400 bird species have been recorded in the northern Peten (Beavers 1992). The site is important for 25 species restricted to the Gulf Caribbean Slope. One of the country's largest wetlands–Laguna del Tigre National Park and surroundings–is located in the northwestern part of the IBA. Based on a continental population estimate (Wetlands International 2006) and local estimates (Eisermann 2006), it is assumed that the site holds important parts of regional populations of Bare-throated Tiger-Heron (Tigrisoma mexicanum), Least Grebe (Tachybaptus dominicus), and Wood Stork (Mycteria americana).
