E.  aPhytosociology of natural and naturalized pastures in Santa Catarina highlands.h[electronic resource]  c2016  aThe natural pastures constitute the main forage substrate in Santa Catarina highlands. Presents an inestimable environmental importance value due to the the diverse number of grasses and legumes species. Despite the importance of the natural pastures, few studies exists about phytosociology on this region. The aim of the study was characterize the plant community of natural pastures in the municipalities of Lages, S??o Joaquim, Painel, Cap??o Alto and Bom Jardim da Serra, and in a naturalized pasture in S??o Jos?? do Cerrito. It was evaluated the phytosociology in a ranch property of each municipality to represent the local physiognomy. Five sample units (SU) of 1 m?? were established in each local in January 2014. It was calculated the values of species presence/absence, absolute percentage of soil coverage and relative coverage. The Shannon Index was calculated using software "R" (vegan package). The survey identified 173 species, the greater species richness were observed in Lages and Cap??o Alto with 30 species / SU, Bom Jardim da Serra and Painel presented 28 species / SU, S??o Joaquim presented 24 species / SU. The lowest richness with 13 species / UA was observed in a naturalized pasture in municipality of S??o Jos?? do Cerrito. Shannon diversity index for Lages was 2,885, Cap??o Alto 2,830, Bom Jardim da Serra presented an index of 2,781, Painel 2,834, S??o Joaquim was 2,640, and finally, S??o Jos?? do Cerrito was 1,930. There was an equitable distribution among species, with a low percentage of relative soil coverage of each specie. The species: Baccharis crispa Spreng., Paspalum plicatulum Michx., Piptochaetium montevidense (Spreng.) Parodi, Gamochaeta americana (Mill.) Wedd., Schizachyrium tenerum Nees, Chevreulia sarmentosa (Pers.) Blake, Axonopus compressus (Sw.) P. Beauv., Baccharis pentodonta Malme, Eragrostis polytricha Nees; and Paspalum notatum Flügg??; composes an absolute soil coverage of 22.51%. There was 2.88% of uncovered soil, and 3.53% of dead material. The natural pastures of the Santa Catarina hightlands in different locals presented similar diversities, while naturalized pastures presents a lower diversity index and richness.  acattle  adiversity index  afloristic diversity1 aBALDISSERA, T.
