The study aimed to determine IVI N, G, V, recruitment, mortality and AAI of trees with DBH≥10 cm, growing the Arboretum “El Huayo” localted in the Forestry Research and Teaching Center of the UNAP, Iquitos, Peru, in the period 2002- 2012. The density ranged from 489 trees/ha to 561,9 trees/ha; the lumber volume increased from 380,5 m3/ha to 467,6 m3/ha in plot I, from 327,8 m3/ha to 510,9 m3/ha in plot II and from 357,9 m3/ha to 383,8 m3/ha in plot III. The floristic diversity appears to be very rich with 384 species in 4,72 ha. Of these, 32 species showed higher IVI, forming the association A. triplinervia - E. grandiflora - C. cateniformis - E. coriaceae - B. utile - T. retusa - P. tomentosa. The Shannon-Wiever index ranged from 2,788 to 3,387 and the Simpson Index ranged from 0,9193 to 0,9515 The similarity between plots III and IV was 77% and 61% between plots I and II. Species with decreasing populations were C. cateniformis (26 dead trees and 4 recruits), J. copaia (16 dead trees and 3 recruits), O. oblonga (24 dead trees and 12 recruits), C. arborea (25 dead trees and 12 recruits) and P. igneiflora (12 dead trees and 7 recruits). Species with inceasing populations were T. retusa (6 dead trees and 50 recruits), P. tomentosa (19 dead trees and 29 recruits), B. utile (4 dead trees and 12 recruits) and S. exorrhiza (9 dead trees and 18 recruits). The average annual growth was 0,61 cm/yr, V. caducifolia grew 3.25 cm/yr, H. excelsum grew 3,11 cm/yr, L. macrocarpa grew 2,34 cm/yr, F. krukovii grew 2,33 cm/yr, V. braceliniae grew 2,26 cm/yr, V. orinocensis grerw 2.15 cm/yr and O. bofo grew 2,08 cm/yr.
