Phytosociological Analysis Open Rainforest Colonization In Different Models Of The Amazon

The aim of this study was to evaluate the influence of colonization models (fishbone and topographic) in different successional stages: Initial (SS1), Intermediate (SS2) and Advanced (SS3) in the Brazilian Amazon, through phytosociological attributes supported by satellite images, and understand the variables that affect the patterns of forest succession and the differences between biometric variables within the different settlements located in the northwestern portion of the state of Rondonia. For that were sampled 56 transects of 10 x 250m in areas of advanced successional stage, 64 transects of 10 x 10 m in areas of intermediate successional stage, and 79 of 2 x 2 m transects in areas of early initial successional stage. In the colonization model called fishbone, were identified 23 families and 43 species - in initial successional stage; in intermediate successional stage were identified 20 families and 41 species already; in advanced successional stage - were cataloged 37 families with 42 species. In the colonization model whose shape is known as topographic, were cataloged on stage SS1, 32 families and 60 species- stage SS2, 29 families and 54 species and stage SS3, 43 families and 57 species. The most important families in the process of succession were the Fabaceae, Caesalpiniaceae, Lauraceae and Bignoniaceae in both models.
