Maracá is a riverine island located in the Rio Urarucoera in Roraima State (Brazil) and has an area of about 100,000ha. A forestt type dominated by Peltogyne gracilipes Ducke (Caesalpiniaceae) occurs on Maracá Island on a range of soil types. This study compares the structure, floristic composition and soil of the Peltogyne forest with the most widespread lowland forest types on Maracá. Three 0.25ha plots were set up in each of forest types: Peltogyne-rich forest (PRF), Peltogyne-poor forest (PPF) and forest without Peltogyne (FWP). Within each plot all trees were recorded. Seedling and saplings were sampled in subplots of 2m x 1m (seegings) and 4m x 4m (saplings). In the PPF and FWP, Sapotaceae were the most important family with the highest relative dominance and relative density values. Caesalpiniaceae showed high values in the PRF and PPF, Licania Kunthiana, Pradosia surinamensis and Simarouba amara ocuurred in the camopy layer in all the forest types. Peltogyne dominated the canopy in the PRF and comprised 20% of stems and 53% of the total basal area of all trees 10cm dbh, and 91% of the stems and 97% of the total basal area of indiviadual 50cm dbh. In PPF, Lecythis corrugata and Tetragastis panamensis were most abundant species, followed by Peltogyne. In the FWP the most abundant trees were Licania Kunthiana and Pradosia surinamensis. In all forest types, the soils were sandy and acid with concentrations of extrctable phosphorus and exchangeable cations, but the soils under PRF were notably richer in magnesium.
