Abstract

ARAUJO, Fernanda Squizzatto de et al. Floristic of shrub - tree vegetation colonizing an area degraded by kaolin mining, in Brás Pires, MG. Rev. Árvore [online]. 2005, vol.29, n.6, pp. 983-992. ISSN 0100-6762.  http://dx.doi.org/10.1590/S0100-67622005000600018.

This study aimed to analyze the floristic composition of shrub-tree vegetation colonizing an area degraded by kaolin mining in Brás Pires, MG, compare it with other forest fragments and characterize ecological aspects of species and soil of the area. The sampled area was 0.5 ha subdivided in 50 grid plots of 10x10 meters each. All individuals included had CAP equal or larger than 10cm. The floristic composition is the result of the sampled area plus species collected outside of it. A total of 64 species was obtained, distributed in 50 genera and 30 families. The families with the greater number of species were Leguminosae (11), Annonaceae (5), Lauraceae e Melastomataceae (4), while the richest genus was Machaerium (3). The soil analysis revealed that it had not impaired the vegetation colonization. The main dispersal syndrome was zoochorous, showing the importance of remnant individuals, surroundings forest fragments and its fauna. The greatest floristic similarity occurred in Cruzeiro, SP, being both areas at the same successional stage.

Keywords : Floristic composition; restoration of degraded areas; mining; natural regeneration.
