Anthropogenic active in forest environmental take formation of small fractions forest separated by large agro-pastoral areas. In the edges of these fragments increase the availability of light, a factor favorable to the establishment and the development of climber plants. This study aimed to characterize the floristic composition and the ecological aspects of the climber plants in three fragments of semideciduos forest in Uberlândia. For the floristic survey were collected monthly from March 2010 to March 2011. The species were classified according the habit, climbing strategy, dispersal syndrome and occurrence. Also compared species richness of our fragments with other semideciduous forests of São Paulo State. We registered 99 species inclued in 25 families and 63 genera. In the fragment of São José was found 72 species, followed by Glória (53) and Irara (52 species). The families richest in species are Bignoniaceae (16), Malpighiaceae (12), Sapindaceae (11), Fabaceae (10), Apocynaceae (9), Convolvulaceae and Asteraceae (5). In the three areas there was predominance of woody species, rare and anemochoric. The species with tendrils were more representative in the Irara and São José, while in the Glória was higher proportions twining species. The three fragments of semideciduos forest in Uberlândia the composition of species were very heterogeneous with low floristic similarity among them and with other fragments placed the São Paulo State. This suggest that climbing plants are structural components of vegetation and not only invasive favored by the fragmentation of forests.
