Abstract
Numa área situada no município de Lavras, MG, o desmatamento realizado há cerca de dez anos propiciou a formação de uma comunidade infestante dominada por Pteridium aquilium (L.) Khun., te ndo como codominantes Imperara brasiliensis Trin. e Andropogon bicornis L.. Como fatores que mantém esta comu nidade devem ser considerados: a) as queimadas intermiten te s; b) a acidez do solo; c) a alta percentagem de saturação de aluminio ; d) a ação fitotóxica do próprio P. aquilinum; e) a falta de palatabilidade das espécies dominantes.
A forest was clearcutted about 10 years ago in Lavras county, MG, Brazil and today a natural successional stage community can be found. The dominant weed, in fitomass, coverage an hcight is the bracken-fern Pteridium aquilinum (L.) Kuhn. The West Indian foxta il (Andropogon bicornis L.) and the brazilian cogon grass (Imperata brasiliensis Trin.) are the co-dominats weeds. Periodic burnings, soil acidity, high aluminium saturation and the phytotoxicity of the P. aquilinum itself are probably the factors which could explain the present community successional stage.
