Only non-invasive technical studies and scientific research, environmental education activities and tourism of low environmental impact and ecological enrichment, that do not imply modifications of the original characteristics or natural conditions, and the construction of support facilities, are exclusively allowed. for scientific research or environmental monitoring. The exploitation activities carried out here must be subject to strict control measures. It is formed by the surfaces where there is a greater use of the territory. It has an area of 5,828.48 hectares and its objective is to guide the exploitation activities that are carried out (milpa, henequen, crops, stone extraction, human settlements, urbanization, agricultural production systems, livestock and forestry), to lead towards the development sustainable, apply the current federal, state and municipal regulations, so that the necessary conditions are created for the reconversion and ecological restoration that allows the conservation of the area in the long term. Vegetation and Flora  The vegetation in the Reserve is low deciduous forest (SBC). SBCs are plant communities that are distributed in hot climates, the driest of the subhumid. These are ecosystems that mark a thermal and hydric limit between the types of vegetation that are distributed in the hot humid climate zones. The arboreal components in this forest reach a maximum height of up to 15 meters and a percentage higher than 75 of the species throw their leaves in the dry season of the year. In the Reserve, SBC occurs on secondary vegetation surfaces in different conservation or succession states. It includes 474 species included in 96 families. The families with the greatest number of species are Fabaceae (58), Euphorbiaceae (30) and Asteraceae (24), which represent 23.5% of the total number of plants registered in the Reserve. In contrast, 33.33% of the families (Adoxaceae, Apiaceae, Araucariaceae, Asphodelaceae, Begoniaceae, Burseraceae, Cannabaceae, Cannaceae, Casuarinaceae, Combretaceae, Cycadaceae, Cyclanthaceae, Dryopteridaceae, Iridaceae, Lauraceae, Loasaceae, Loranthaceae, Menispermaceae, Moringaceae, Muntingiaceae, Oxalidaceae, Papaveraceae, Piperaceae, Plantaginaceae, Ranunculaceae, Scrophulariaceae, Ulmaceae, Violaceae, Vitaceae, Zamiaceae and Zygophyllaceae) are monospecific. Nine species (1.9%) are classified as at risk in the Official Mexican Standard NOM-059-SEMARNAT-2010, Environmental protection-Species native to Mexico of wild flora and fauna-Risk categories and specifications for inclusion, exclusion or change-List of species at risk.
