Sumario: | The most important environmental transformations that occur on the ecosystems are the urban settlements that expand in a disorderly way, especially in the foothills of Mendoza, Argentina. Urbanization implies clearing affecting the permanence of biodiversity that depends on vegetation to complete its life cycle; when species are lost, genetic material is lost. To know the percentage of built and unbuilt areas; and the impact on the native vegetation of the study area, the piedmont was analyzed in the Pérez Guilhou Allotment, Vertientes del Piedemonte, Luján de Cuyo, dividing it into consolidated piedmont (PC) and unconsolidated piedmont (PNC). In PC, the vegetation was recorded through the blocks. In PNC, transects were covered, the vegetation was surveyed using modified Point Quadrat. Specific plant richness was obtained (In PC, 15 autochthonous plant species and 56 introduced. In PNC, 50 autochthonous species and 9 introduced. Regarding the percentage of built and unbuilt spaces; of 200 ha, in PC, 85% were built and 30% not built.In PNC, of 400 ha, 58% corresponded to built land and 41% not built.It is concluded that, in PC, there is a higher percentage of buildings, and a predominance of exotic plant species; unlike PNC with conflicting values |
