Floristic composition, species diversity, density and frequency were studied in primary forest and different stages of succession (early abandoned psture; two year, three year, four year, five year and ten year old capoeira). Species composition of primary forest, as represented by plants with a girth greater than 30cm, comprised 115 to 221 species/ha depending on location. Species diversity was high and the plant community was characterised by a few dominant species with many individuals and a large number of rare species. In successional vegetation, species composition changed over time showing three clear stages: herbaceous-graminoid, shrubby and arboreal. The diversity was high and tended to increase over time while the number of individuals per species decrease. Frequency of occurrence patterns were similar those found for primary forest. Standing biomass and nutrient content: litterfall, ash production and their potentially available nutrients were studied in selected stages of succssion. Primary biomass at different locations ranged form 374ton dry weight.ha-1 to 522ton dry weight.ha-1 (mean +- SD = 468ton.ha-1 +- 66ton.ha-1) while in secondary vegetation it was more variable depending on age and previous land use (range: 5.54ton.ha-1 in abandoned pasture to 53.2ton.ha-1 in 2-year old capoeira). Similar amount of nutrients were released via ash from primary forest and a 20-year old capoeira: but the total nutrients in litterfall proved to be highest in primary forest. The impact of four methods of land clearance (slach + burn, slash + herbicide, slash + bur + herbicide and bulldozer) on seed banks and early stages of succession were also studied. Bulldozer was the most and slash + herbicide the least, deleterious treatment according to the attributes under study.
