Dinâmica da vegetação arbórea da mata de galeria do Catetinho, Brasília-DF

Abstract

The dynamic in Catetinho s gallery forest, Brasília DF, was studied over an eleven years period (1994 - 2005). Three transects of 10m of width and variable lengths, according to the forest s limits, were systematically implanted, placed at 100 m from each other and perpendicular toGama s stream, covering a gradient that extended fromthe headboard streamto a downstream. Each transect was subdivided in permanent sample plots of 200 m2 (10 m x 20 m) being possible to allocate a total of 33 plots. In each plots all the woody individuals were registered with DBH 5 cm. In 1994, results showed 948 alive individuals, distributed in 93 species of 50 families; and, in 2005, 655 alive individuals, distributed in 93 species of 47 families. The mortality rate obtained for the community was 5,55% and the recruitment, 1,42%; while the annual periodic increment in diameter was 0,20 cm.year-1.
