Cuxtal Ecological Reserve
Ecological Preservation Area in Yucatán, Mexico From Wikipedia, the free encyclopedia
The Cuxtal Ecological Reserve (IPA: [kuʃˈtal], from the Mayan language meaning "life") is located in the southern zone of Mérida Municipality, between 20° 47' and 20° 55' of north latitude and 89° 33 and 89° 40' of west longitude. The Reserve limits to the north with the city of Mérida, south with the commissariats of Yaxnic and Texán Cámara, east with the municipality of Kanasín and west with the commissariats of San José Tzal and Ticimul. It provides 50% of the water in the City of Mérida and is home to 168 bird species, most of them migratory, as well as plants, mammals, reptiles, invertebrates and amphibians.[3] It contains 7 historic haciendas, archaeological sites, cenotes as well as a nature preservation and the Biological Sciences campus of the Autonomous University of Yucatán.

The Zone Subject to Ecological Conservation Cuxtal Reserve is recognized as the first Protected Natural Area (ANP by its initials in Spanish) promoted and decreed directly by a municipality in the state of Yucatán during the Mérida City Council 1991–1993. Its establishment as ANP was approved by the council on June 28, 1993, and its decree was published in the Official Gazette of the Government of the State of Yucatán on July 14, 1993. In this way the Reserve was constituted as the first ANP of competition municipal government in Yucatán, a situation that prevails today.
In December 2016 the initiative called "Alliance for Cuxtal" was formally set up constituted by government agencies, educational institutions, civil associations and the private sector, to promote actions aimed at the rescue and preservation of the Reserve.
In February 2017, the agreement is published authorizing the creation of the Decentralized Municipal Public Organization for Operation and Administration of the Cuxtal Reserve Ecological Preservation Area. In subsequent months, its Governing Board, the advisory board and the Operational Directorate are set up, which will favor the operation, management and administration of the Reserve.
It has an area of 10,757 hectares. The Reserve limits to the north with the city of Mérida, to the south with the commissariats of Yaxnic and Texán Cámara, to the east with the municipality of Kanasín and to the west with the commissariats of San José Tzal and Ticimul. Within its territory are two commissariats: Dzununcán and Molas, seven sub-commisariats: Santa Cruz Palomeque, Tahdzibichén, Xmatkuil, San Pedro Chimay, San Ignacio Tesip, Hunxectamán, Dzoyaxché and a conurban area with 10 colonies of the city of Mérida belonging to the Dzununcán commisariat, Xmatkuil sub-commissariat and parts of San Antonio Xluch and Kanasín.
Zoning is the tool that defines the zones or subzones of the Reserve according to criteria that allow the identification of territorial geographical units where specific use rules are applied according to protection requirements, which makes the conservation process more effective, without diminishing the potential management and sustainable use of their natural resources.

Core zone
It is formed by the best-preserved surfaces and which have arboreal vegetation whose geographical location favors long-term conservation. It has an area of 4,928.52 hectares and its main objective is the preservation of ecosystems and their functionality in the medium and long term, so only current conditions. It is the main area to conserve the water that supplies the entire municipality of Mérida and its inhabitants.
The Mérida I water treatment plant is located in the core area of the Reserve, where the best-preserved area of forest vegetation is located, which in turn represents the main area for extracting groundwater for the purpose of supplying the entire municipality of Mérida. , with a volume of 42.3 mm3 per year that is equal to 48% of the total extraction.
Sub-zone of protection
It is formed by surfaces that have undergone little alteration and represent critical habitats for biodiversity, so they require special care to ensure their long-term conservation. It has an area of 2,716.38 hectares and its objective is the conservation of less disturbed and more representative areas of the low deciduous forest ecosystem. This sub-zone is represented by the forest vegetation of the Mérida I water treatment plant and partially by the ejidos of Molas and San Pedro Chimay.
Only non-invasive technical and scientific research studies are allowed, which do not involve the extraction or transfer of wildlife specimens, or habitat modification.
Sub-zone of restricted use
It is formed by the surfaces in good state of conservation where it is sought to maintain the current conditions of the ecosystems and even improve them in the places that are required, through agroecological options. It has an area of 2,212.14 hectares and its objective is to promote connectivity and the preservation of germplasm.
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.
Buffer zone
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.
