The importance of climber synusia on ecological restoration process by brushwood transposition from cerrado Veridiana Weiser Osmar Cavassan Isabela Souza

RESTORATION ECOLOGY Restoration Ecology is the re-establishment of damage ecosystems, as closest as possible from its original condition (The Brazilian Federal Law number 9.985, from July 18 th of 2000). Talita Hayata Talita Hayata Talita Hayata original damaged re-established

NUCLEATION Nucleation is an ecological restoration method, which implements the natural succession in degraded ecosystems, restituting its biodiversity (REIS et al. 2003). Ecological Succession Ricardo Ribeiro Rodrigues

BRUSHWOOD TRANSPOSITION Brushwood transposition is a nucleation technique, which consists in accumulation of branches and forest residues, disposed as nuclei along the restoration area (REIS et al. 2003). Veridiana de Lara Weiser

We aimed to know the climber synusia of an ecological restoration area by brushwood transposition from cerrado, answering the questions: Are the species the same ones that occur in other neighboring cerrado fragments? Is there a prevalence of herbaceous climbers, twiners, and wind dispersed species, indicated in the literature as the most frequent in disturbed habitats?

88% of climbing species occur in cerrado. Exceptions: Veridiana de Lara Weiser Veridiana de Lara Weiser CONVOLVULACEAE CONVOLVULACEAE Ipomoeae saopaulista O’Donell Ipomoeae nil (L.) Roth Veridiana de Lara Weiser CUCURBITACEAE Ceratosanthes multiloba Cogn.

52% of climbing 60% of climbing species were vines. species were twiners. Veridiana de Lara Weiser 68% were wind dispersed species.

CLIMBERS IN RESTORATION AREAS Use the windrows for densifying their foliage, providing a protected environment to fauna. Contribute to litterfall increase and consequent increased of nutrients availability in soil. Produce nectar, pollen and fruits that attract predators, pollinators, decomposers and dispersers, promoting islands of diversity.
