Southern Peru is a center of high biodiversity, although some areas are poorly investigated and are being decimated by anthropic activities. This study evaluated the composition, structure, diversity and tree biomass of the Amazonian Castañal Forest – IIAP, in the Madre de Dios region. Using a one-hectare plot, they evaluated the composition, height and diameter distribution (DAP) and the Importance Value Index. Tree biomass was estimated with Chave allometric equations. 464 individuals were evaluated, from 197 species, 125 genera and 46 botanical families; Fisher's Alpha diversity was 129. The most diverse families were Fabaceae, Moraceae, Malvaceae. The most diverse genera were Inga, Licania, Naucleopsis, Neea and Ocotea with five species each. The species with the highest Importance Value Index (IVI) were Euterpe precatoria (8.48), followed by Leonia glicycarpa (8.29) and Iryanthera laevis (8.06). Biomass reached 283.56 tons/hectare, with Handroanthus serratifolius standing out with 35,028 (t/ha), representing 12.13% of the total, and Bertholletia excelsa with 25,146 (t/ha). These results are key for planning forest conservation and management strategies in the Madre de Dios region.
