Conteúdo: 	Natural pastures has a high variability in different landscape scales. In the Santa Catarina
highlands soil factors as shallow soils, rock outcrop, high land slopes, and low soil fertility are
someone of vegetation conditioning factors in each location. The improvement of natural
pastures with the correction of soil fertility and oversowing of cool-season species is a
commonly alternative used by local producers. The aim was to study the plant community in
natural and naturalized pastures with human intervention. It was evaluated phytosociology
parameters in ranch properties in the municipalities of Lages, São Joaquim, Painel, Capão Alto
and Bom Jardim da Serra with improved natural pastures and in São José do Cerrito with
improved naturalized pastures. The improvement is with correction of soil fertility based on soil
analysis. The species introduced were: rye (Secale cereale) oat (Avena sativa), annual ryegrass
(Lolium multiflorum Lam), white clover (Trifolium repens), red clover (Trifolium pratense),
dactyl (Dactylis glomerata) meadow soft grass (Holcus lanatus) and birdsfoot trefoil (Lotus
corniculatus). Five sample units (SU) of 1m 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 147 species, the greater species richness were observed in São Joaquim with 27
species / SU, Bom Jardim da Serra with 24 species / SU, Capão Alto presented 23 species / SU,
Lages and Painel presented 21 species / SU. The improved naturalized pasture in São José do
Cerrito presented the lowest value with 12 species / SU. Shannon diversity index in São Joaquim
was 2,745, Bom Jardim da Serra 2,052, Capão Alto 2,402, Lages 2,630 and Painel 2,470. In São
José do Cerrito Shannon index was 2,051. The introduced and native species represent 12.18%
and 13.66% of relative soil coverage, respectively. The ten species with the greatest contribution
was: Trifolium repens L., Trifolium pratense L., Lotus corniculatus L., Holcus lanatus L., and
the native species was Axonopus compressus (Sw.) P. Beauv, Paspalum plicatulum Michx.,
Paspalum notatum Flu&#776;gge, Hypoxis decumbens L., Cyperus hermaphroditus (Jacq.) Standl., and
P. dilatatum Poir. Improvements of natural pastures presents higher plant diversity than
improvements of naturalized pastures.
