Estructura y composición de la vegetación de la barra costera El Mogote, Baja California Sur, México
Located in the southern region of the east coast of the state of Baja California Sur, the large sand bar, called El Mogote, is covered in 15.5 km2 of surface by vegetation whose features are particular of the merging of sandy coastal environments, the arid-tropical Cape Region, and the Sonoran Desert. We analyzed the vegetation by classification and ordination techniques to establish relationships between vegetation and edaphic gradients, identifying nine plant associations in three environments: dunes, salt flats, and mangrove. The vegetation gradient in the dunes is explained by salinity and size of soil particles. Some ecological variations account for species richness and diversity, which are higher in the protected surfaces containing more stable soil than in wind exposed areas. Vegetation in this area is threatened by a residential and touristic infrastructure and construction.
