ABSTRACT
The vegetation of the Poço das Antas Biological Reserve located in Silva Jardim municipality is composed of abandoned farmland and secondary forests fragments at different stages of development. A study of the floristic composition and structure of the shrub and herbaceous layer of an old field was conducted, aiming to obtain informations that might assist studies on natural regeneration of the site. The study area consists of an area that was once covered by forest and was used as pasture before the creation of the Biological Reserve. It is now covered by grassy vegetation with sparsely scattered woody plants or small thickets. The point method was used in the vegetation survey (total of 300 point). Grass species as Imperata brasiliensis, Lygodium volubile and weedy species as Blechnum serrulatum are dominant.
