Resumo: |
Biodiversity at all have been intensively threatened by forest fragmentation. Fragments situated nearby major natural areas are important to some animal populations and avifaunal inventories are important because they can play an important role in the environmental evaluation of these areas. This paper records a qualitative and quantitative inventory of the bird community that occurs in two Cerrado fragments situated next to the Estação Ecológica de Itirapina, a very important conservation unit to São Paulo State. The Vermelhão fragment has 350 ha and the other one, Valério, is about 150 ha of natural Cerrado vegetation. The qualitative portion of the inventory was made by walking in the areas. For the quantitative portion we used the point counts with unlimited distance methodology. A total of 213 species were observed between August 2006 and October 2007, within 53 new records to the region. The species list indicates eight threatened species in the state and five considered endemics of Cerrado. Observing the abundance index values (IPA) we realize that there are few species with a high IPA and a large number of species with intermediate and low rates. Most species were registered until 50% of the visits to the areas. Results show these fragments importance to the conservation of local biodiversity. |
