Habitat loss, among others consequences, reduces specie populations size of plants and animals, there is a minimum amount of necessary habitat to the persistence of a population in a given landscape: it is the concept of "extinction threshold" and to know what is the minimum amount of habitat necessary to the persistence of different species is the goal of several researches. Some studies assess that the minimum proportion of suitable habitat for populations, generally, remain in a given landscape is about 20-30%, but this minimum can vary from species to species.Although many studies that show a positive relationship between the proximity of native vegetation and an increase in richness and diversity of bee species, others sort of environment also can contribute to the maintenance of bee populations in anthropic landscapes. Knowing that the distances foraging to the most of bee species (especially solitary bees) are only a few hundred meters, it is necessary that the resources for them required are supplied within this flight range.Seeing that the solitary bee species are more sensitive to environment changes, their presence and abundance can be indicative indirect of the quality of pollination service held in the region. The current project has like main goal to analyze what are the nested effects (fine and regional scale) of native vegetation amount and landscape heterogeneity on cavity nesting bee community in Cantareira-Mantiqueira region. The information generated by the current project can help in future studies about ecosystem services assessment provided by Atlantic Forest remaining vegetation, mainly the pollination, as well as to help environment education programs with the farms in the study area, focusing in the solitary bee species with potential to pollinate crops.
