Biodiversity of riparian vegetation under a management gradient in the Monarch Butterfly Biosphere Reserve, Mexico
Abstract Background: Rivers and their associated vegetation are considered highly complex natural systems representing high biodiversity areas that work as biological corridors. Nevertheless, riparian vegetation of the Monarch Butterfly Biosphere Reserve (MBBR) has not been studied nor considered in the reserve’s management program. Questions: Which is the composition, structure, diversity, and state of conservation of the riparian vegetation of the MBBR? Study site and dates: The Senguio Microbasin, part of Sierra Chincua Priority Terrestrial Region, within the MBBR, in central México. 2016-2017. Methods: Using high-resolution imagery from 2014, we identified five joint categories in relation to the protection status (Core Zone, Buffer Zone, and Influence Area) and land use (conserved forest, highly disturbed forest, and farmland). We sampled three sites per category (N = 15) to analyze the composition, richness, and α and β diversity of the riparian communities. Results: We registered 108 species, 46 genera, and 18 families, of which 98 % are native and 2 % exotic. Richness and α-diversity were not significantly different among sites, but the composition and β-diversity showed significant differences depending on land use. The riparian vegetation is well conserved both in the Reserve´s Core and Buffer zones, and preserves high coverage, species richness, and individuals’ abundance. Conclusions: The riparian vegetation of the Senguio Microbasin hosts a biodiversity richness critical for the ecosystem’s health and evidences the relevance of considering the human use of the riparian systems to succeed in the conservation strategies.
