To evaluate the impacts of timber harvesting, temporary sampling plots were installed, 04 for trees> 10.00 cm and 25 in <9.9 cm of DBH (diameter at breast height) divided into size categories A, B, C, D and E. At the level of species and families (> 20.00 cm and 10-20 cm DBH, A and B) there were no significant differences of abundance by forest type, altitudinal floor (low and high hill) and interaction, with greater abundances of Brosimum alicastrum; there is a significant difference of species dominance by forest type and altitudinal floor with highest average of “forest not intervened“; greater abundance of moraceae, fabaceae and lauraceae and higher frequency of species of lower commercial value, B. alicastrum and Pseuldemendia rigida. In trees with 10 - 19.9 cm of DBH the statistical significance was similar, higher abundance in B. alicastrum high hill (11.63%) and in low hill, Amburana cearensis with frequencies of higher value species in the “no Intervened“- high hill, B. alicastrum 6.10% and Terminalia oblonga 4.90% and in low hill, A. cearensis 3.60%. Impacts on trees <9.9 cm of DBH were 38.7% by partial felling and 28% “without disturbance“; 64.47% in the “not intervened“; The impact was lower in the smaller categories (E: <5.0 cm DBH and <2.0 m height) that did not depend on the clearings, with the abundance being greater in the “forest intervened“ of Myrsine pellucida in “C“; B. alicastrum in “D“ and Couma macrocarpa in “E“. In conclusion, in the “non-intervened“ forest, there is a greater abundance of timber species, trees> 10 cm of DBH in both hills and <9.9 cm of DBH associated with heliophytes and escifitas of greater and smaller commercial value, Such as Cedrela fissilis, Clarisia racemosa, Hura crepitans and “oaks“.
