Resumen
HERNANDEZ-NAVA, José; PASCUAL-BARRERA, Alina Eugenia; ZALDIVAR-JIMENEZ, Arturo y PEREZ-CEBALLOS, Rosela. Structure and carbon sequestration in urban mangroves, fundamentals for conservation in Isla del Carmen Campeche, Mexico. Bot. sci [online]. 2022, vol.100, n.4, pp.899-911. Epub 01-Ago-2022. ISSN 2007-4476. https://doi.org/10.17129/botsci.3048.
Background:
In the Yucatan Peninsula, some mangrove areas were filled with rubble and residential areas were latter developed.
Questions:
Can the knowledge of the forest structure and carbon storage be used to establish a baseline for urban mangrove conservation?
Study species:
Rhizophora mangle L., Laguncularia racemosa Gaertn f., Avicennia germinans L. y Conocarpus erectus L.
Location and study year:
Isla del Carmen, Campeche, 2017.
Methods:
Sampling units were established for assessing vegetation structure and measuring above-ground and below-ground carbon stock in two mangrove zone; the first one was filled with rubble and the second without land use changes.
Results:
The site filled with rubble had a basal area of 25.4 m2 ha-1, where A. germinans was the dominant species with stand density of 675 trees ha-1, with average height of 5.5 m and average diameter at breast height of 13.4 ± 1.6 cm. The site without land use changes had a basal area of 27.8 m2 ha-1 and A. germinans was also the most abundant species with 731 trees ha-1, but individuals were smaller (5.0 m tall) and with greater diameter at breast height (15.2 cm), as compared with the other site. The estimated total carbon stored in the second site (383 Mg C ha-1) was higher than in the first one (321 Mg C ha-1).
Conclusions:
The ecological value of carbon sequestration and forest structure contributed to strengthening the conservation and protection measures against invasions of urban mangroves.
