The structure dynamics of an understorey vegetation influenced by gaps caused by reduced impact logging was analyzed during 12 years in a terra firme rain forest in the municipality of Moju, Pará state, eastern Brazilian Amazon forest. Angiosperm individuals from 10 cm height up to 5 cm DBH were surveyed in a 468 m² sample area in six occasions (1998, 1999, 2000, 2001, 2007 and 2010), they were analyzed considering their life-forms (trees, shrub, lianas, herbs and palms), abundance, frequency, size classes (CT1 = 10 cm ≤HT <50 cm; CT2 = 50 cm ≤HT ≤ 130 cm; CT3 = 130 cm
