Resumo

Foi realizado o levantamento florístico do estrato arbóreo na RPPN Porangaba (Itaguaí, RJ). Foram amostradas 50 parcelas de 100 m2, nas quais todos os indivíduos com DAP ≥ 5 cm foram mensurados. Foram amostrados 943 indivíduos (877 vivos), distribuídos em 36 famílias, 66 gêneros e 105 espécies. As espécies com maior VI foram: Guarea guidonia (L.) Sleumer, Piptadenia gonoacantha (Mart.) J.F. Macbr, Casearia sylvestris Sw. e Bathysa gymnocarpa K. Schum. As famílias mais representativas foram Fabaceae (S = 14), Myrtaceae (S = 11) e Moraceae (S = 6). A área guarda uma representativa diversidade da floresta submontana, mas ainda são necessários estudos sobre a dinâmica da comunidade vegetal da RPPN Porangaba.

Abstract

We have performed a floristic inventory of the tree layer at RPPN Porangaba (Itaguaí, RJ). We have sampled 50 plots of 100m2 where all individual trees with DBH ≥ 5 cm were measured. We have sampled 943 individual trees (877 births), distributed in 36 families, 66 genera and 105 species. The species with higher VI were Guarea guidonia (L.) Sleumer, Piptadenia gonoacantha (Mart.) J.F. Macbr, Casearia sylvestris Sw. and Bathysa gymnocarpa K. Schum. The most representative families were Fabaceae (S = 14), Myrtaceae (S = 11) and Moraceae (S = 6). The area holds a representative diversity of submontane forest, but studies are needed on the dynamics of plant community of RPPN Porangaba.
