The state of Santa Catarina has a gap in his ornithological knowledge, with your plateau
area, once covered by the Araucaria forest, neglected when it comes to knowledge of its
avifauna. This work aimed to study the birds occurring in a timber-producing farm in Rio
Negrinho, SC, covering the occupation of the species in different vegetation succession, and
an approach on the correlations between birds and plants dispersed by them, seeking a new
focus within the processes of restoration of environments. There was a wealth of 261 bird
species, covering a wide variety of successional stages, including 11 endangered species
and three new records for the state. This wealth can be considered high when comparing
with other work in areas of pine plantations with different management methods. Of the total,
47 species showed a high frequency of occurrence (FO), 74 an average FO and 124 low, the
standard expected for tropical rain forests of character. During the sampling period with mist-
nets, was captured a total of 557 individuals belonging to 77 species. The species with the
highest relative abundance was Haplospiza unicolor, due to a natural event of great
magnitude: the harvest of two species of bamboo belonging to the genus Merostachys,
which influenced the landscape and consequently the composition of the avifauna. The
environment formed by the advanced stage showed the highest capture rate (n=200),
followed by initial (n=191) and intermediate (n=85). This succession of birds revealed
differences in the occupation of niches by some groups according to the environment.
Sampling in areas of pine plantations have shown a difference in the use of them, according
to their age, and areas with more than 15 years had a more diverse bird life, when performed
management techniques employed in the sampled area. As concerns the frugivory and seed
dispersion, 22 plant species were seen being dispersed for 59 species of birds. The total
network of interactions showed a visible nestedness. Nested networks are less likely to loss
of species by elimination of one of these, since it is a cohesive network. The value of this
work was presented connectance of 0.256, intermediate value expected in tropical forests
that have been changed. Myrsine coriacea presented like as the key resource for maintaining
the birds, with four Melastomataceae (Miconia cinerascens, M. petropolitana, Ossaea sp.
and Leandra sp.) and four species of pioneer character. The production of fruits of
Lauraceae correlated with the existence locally of migratory birds, which have a
preponderant role in the dispersal of their seeds. Within the methods used in environmental
restoration nucleation, were described several aspects of the importance of birds in this
process, supporting well, improvements in the development of these techniques according to
the birds occurring.
