Description Fragmentation is one of environmental degradation and reduction of biodiversity causes, including in bird communities, mainly in Atlantic Forest areas. The aim of this study was to evaluate the differences in richness and functional groups structure in the ornitofauna from a Restinga forest fragment and four areas with different ages of reforestation. We selected five forest fragments in a Restinga area in the state of Paraiba. A native fragment (Control Area-AC) and four fragments that have undergone a mining process and present different ages of reforestation (1989, 1997, 2001 and 2003). The avifauna samples occurred in four expeditions between November 2006 and April 2008 and counted with a total effort of 2700 net.m2 per expedition. Statistical tests verified richness differences between studied areas, as well as the composition of their functional groups. In general, 90 bird species were recorded, and the highest reforestation age area presented the highest richness (n = 51 spp.). The species richness comparisons indicated that the difference in the richness between AC and reforested areas is not statistically significant. The similarity analysis indicates that reforested areas share a large amount of species and AC has a great differentiation in composition. This differentiation is explained by the significant presence of frugivorous, nectarivorous, leaf and understory-insectivorous species. Changes in species richness and composition in degraded areas are expected and reforested areas usually have a smaller number of forest-dependent species due to the deficiency of available resources. The recovery of areas by reforestation are important conservation strategies, however there is need for management measures that promote the enrichment of these areas and the availability of resources for species dependent on environments Forest.
A fragmentação é uma das causas da diminuição da biodiversidade, principalmente em áreas de Floresta Atlântica. Este estudo avaliou as diferenças na riqueza e estrutura de grupos funcionais na ornitofauna de um fragmento nativo de floresta de restinga (Área Controle – AC) e quatro fragmentos com diferentes idades de reflorestamento (reflorestados em 1989, 1997, 2001 e 2003). O levantamento da avifauna ocorreu entre novembro de 2006 e abril de 2008 e totalizou um esforço de 2700 rede.m2, por expedição. Foram registradas 90 espécies. A área com a maior idade de reflorestamento deteve a maior riqueza (n = 51 spp.). As diferenças entre as riquezas de AC e as áreas reflorestadas não foi estatisticamente significante. A análise de similaridade apontou um grande compartilhamento de espécies entre as áreas reflorestadas e uma diferenciação em AC. Essa diferenciação é explicada pela presença de espécies dependentes de floresta em AC. Mudanças na riqueza e composição de espécies em áreas degradas são esperadas. Áreas reflorestadas normalmente apresentam menos espécies dependentes de florestas devido a deficiência de recursos disponíveis. Reflorestamentos são estratégias de conservação importantes, contudo há a necessidade de medidas que promovam o enriquecimento destas áreas e disponibilização de recursos para espécies dependente de ambientes florestais.
