Resumo: | A quali-quantitative survey of avifauna was earried out at the Santa Genebra forest reserve (MSG) in order to evaluate the current state of conservation of this important conservation area in the interior of São Paulo Stale. The qualilative survey recorded 134 species and the quantitativo survey through unlimited distance point counts recorded the abundance of 97 species. The low number of species recorded in both surveys was due to the small size (251 ha) and the high degree of isolation of the MSG. These factors plus the extensivo degradation of the forest cover prevent recolonization of extinct species and allow the expansion of some species tolerant to disturbance. The quantitative survey showed some species with an unusually high abundance index. The abundance of most species at MSG is higher whon compared with other areas of similar vegetation which are not fragmented and isolated, There was no striking seasonal variation in the number of birds recorded. These caracteristics could be interpreted as resulting from the density compensation phenomenon. The structure of the bird community of MSG resembles that from an island with low number of species but overall density similar to that of the mainland, leading to a higher density per species. The process responsible for these patterns seems to be related to the habitat appropriateness, mainly because the MSG is completely isolated from other forest arcas. |
