Levantamento de espécies de cobertura vegetal nativas e exóticas encontradas no campus oeste da Universidade Federal Rural do Semi-Árido.

Deforestation is the process of disappearance of forest masses, basically caused by human activity, with the withdrawal of the vegetation cover in particular area for commercial use of wood, deployment of agricultural projects and also in urban expansion. As in any area that needs a plant cover, the UFERSA also faces a frequent problem, replanting trees invasive alien, instead of native to the region. This way the objective of the present work is to not only assess and map the density of the flora of the site but also highlight potential problems and provide solutions. We sought to divide the vegetation in two groups: the native and exotic. Was performed the demarcation of points of agreement with the location of the species, with the purpose of identifying and quantifying the species of native and exotic plants. Among all the species sampled, 24 species (25.3%) are representatives of native species and 71 species (74.7%) are exotic. The afforestation of UFERSA follows the pattern observed in the majority of public green areas of the Brazilian cities with large number of exotic species in relation to the native. In view of a better physical structure, it is evident the need for a greater afforestation, having as encouraging the planting of native species, which provide shade, food and serve as a shelter for the local fauna, not only in UFERSA, but throughout the region that is losing its natural flora in favor of exotic plants.
