Análise florística e estrutural de uma floresta em diferentes estágios sucessionais no município de Castanhal, Pará

摘要: The objective of this study is to understand secondary forest succession through florisitc and structural analysis a in three successional stages (4, 8 12 years) located Castanhal the state Para. This considers wood species divided into two DBH classes: class I (DBH>1cm) II (DBH<1cm). Class individuals were measured twelve 10m x plots 12-year-old forest, four 10 m 4 8-year-old stands. 48 subplots 1m stand, 16 In I, 18, 30 73 identified; found 12, 18 21 individuals/ha 4, forests, respectively. II, 17, 62 50, 26 47 individuals/m2 For Lacistema pubescens, Vismia guianensis Myrcia sylvatica demonstrated greatest abundance relative dominance. guianensis, Miconia ciliata, bracteata Banara also displayed an elevated number individuals. presented stages. Similarity among was approximately 60% for 42% II. results showed with development: initiation phase (4 years), exclusion (8 beginning understory reinitiation (12 years).
