RESUMOEste estudo teve como objetivo avaliar a regeneração natural em três áreas de cerradão sob diferentes tipos de interferência, em Jataí -GO. Foram alocadas 30 parcelas de 5 x 5 metros, sendo 10 em cada área. Estas áreas foram denominadas como preservada, pastoreio e queimada. Foram levantados todos os indivíduos com DAP ≤ 5 cm e altura ≥ 30 cm. As espécies foram classificadas quanto a composição florística e a diversidade da regeneração natural foi estimada pelo índice de diversidade de Shannon e pelo índice de equabilidade de Pielou. Para avaliar as possíveis diferenças entre as médias das variáveis: densidade, diâmetro médio à altura do solo, altura média e riqueza nas áreas em diferentes condições avaliadas (preservada, queimada e pastoreio), aplicou-se o Teste t (p<0,05). Nas áreas que sofreram interferência (pastoreio e queimada), as plantas em regeneração natural tiveram menor desenvolvimento em altura e diâmetro em relação a área preservada. A interferência do gado nos fragmentos de cerradão estudados é mais impactante. PALAVRAS-CHAVE: cerradão, conservação, impacto ambiental. EVALUATION OF NATURAL REGENERATION OF CERRADO IN DIFFERENT CONDITIONS OF DISTURBANCE IN JATAÍ-GOABSTRACT The objective of this study was to evaluate the natural regeneration in three areas of forested savanna under different types of interference, in Jataí -GO. 30 plots of 5 x 5 meters were allocated, of which 10 in each area. These areas were designated as preserved, grazing and burned. All individuals with DBH ≤ 5 cm and height ≥ 30 cm were evaluated. The species were classified as floristic composition and the diversity of natural regeneration was estimated by the Shannon diversity index and the Pielou equability index. The t-test (p <0.05) was applied to evaluate the possible differences between the means of the variables density, mean diameter at ground level, average height and richness in the areas under different conditions (preserved, burned and grazing). In the areas that underwent interference (grazing and burning), the plants in
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
