FLORISTIC SURVEY OF ARBOREAL STRATUM OF THREE FRAGMENTS OF RIPARIAN FOREST AS A SUBSIDY TO ‘ RIO CEDRO’ VEGETATION RECOMPOSITION IN MONTES CLAROS – MG

Abstract

http://dx.doi.org/10.5902/1980509813322The objectives of this study were to know the floristic composition of three fragments of riparian forest fromRio Cedro, Montes Claros, Minas Gerais state and select species to be used in its recomposition. It was donea floristic survey, similarity analysis and sucessional classification of species. We sampled 356 individuals inthree fragments, and: 99 at the 1st one, 117 at the 2nd one and 140 at the 3rd one with a total of 53 species,2 unidentified, 46 genera and 22 families. The majority floristic wealth was found at the 1st fragment:28 species, then at the 2rd one with 26 last at the 3nd with 25. The families with the highest number ofindividuals were Fabaceae (111), Malvaceae (50), Arecaceae (45), Anacardiaceae (32). The Fabaceae familyshowed the greatest number of species represented. By the tests, Sorensen’s similarity rate was obtained forthe fragments: 1 and 2, 52.8%, 2 and 3, 40% and 1 and 3 33.3%. The greatest wealth of pioneering speciesand secondary ones characterize an initial phase of transition from forest pioneering, typical of sucessionalmedium probation and show characteristics of seasonal decidual forest. The fragments studied are disrupted.In order to the recomposition of the riparian forest, a selection of species to be used in its recomposition andthe combination of different ecological groups are proposed.
