SHRUBBY TREE COMPONENT OF RIPARIAN CORRIDORS IN RESTORATION AND NATURAL REMAINING AREAS OF MATRIX FORESTRY, RIO NEGRINHO, SC STATE

Abstract

http://dx.doi.org/10.5902/1980509814578The aim of this study was to analyze the shrubby tree component in riparian corridors in restoration process and natural remainders in a matrix forestry. We identified the richness, diversity, dispersal and pollination syndromes of the individuals and estimate the floristic similarity. The study was conducted at the producing farm of Pinus spp. wood Santa Alice, located in Rio Negrinho city, Santa Catarina state, Brazil. We adopted the center-quarter method for survey the shrubby tree component in four sample groups: CA (advanced stage of riparian corridors vegetation), CR (riparian corridors in restoration), MA (advanced stage of natural remaining), MI (intermediate stage of natural remaining). We found the highest richness and diversity index in MA and CR. Regarding the number of individuals, the dispersal and pollination syndromes predominant in all sample groups were zoochory and zoophilia. CR and CA had the highest percentage of floristic similarity while MA and MI did not form clusters. The sample group CR has composition, richness and diversity more similar to CA. This indicates that the restoration of riparian zones has conditions to rescue the components and the interactions of an ecological community.
