Resumen:
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 Mexico. 20162017.
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 alpha and beta 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 alpha-diversity were not
significantly different among sites, but the composition and
beta-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.
