This work aimed to determine the floristic composition and species aggregation indexes for the natural regeneration of a tropical moist forest in Manaus region, managed under four different levels of harvesting. Silvicultural treatments presented some influences on the total number of individuals and the number of individuals per size class. The floristic compositon presented with 56 different botanical families (29) differen species withing 169 different general. The control plot presented the smallest number of species. The homogeneity level and Jentsch mixture quotient were low, i. e., the studied forest ins heterogeneous. The dominant families were: Bursceraceae, Annonaceae, Violaceae, Melastomataceae e Rubiaceae,. The families which presented the highest diversity were: Caesalpiniaceae, Sapotaceae, Lauraceae e Mimosaceae. The Fracher & Brischle index presented higher number of clustered species in all four treatments, while the Payandeh index presented higher number of non-clustered species. |
