http://dx.doi.org/10.5902/1980509814583Height periodic annual increment (2005-2010) of seedlings of Parkia gigantocarpa Ducke planted in gaps caused by logging, in the municipality of Paragominas, state of Pará (3º 30’S; 48º 45’W) was evaluated. Three gap sizes were considered: small gap (200-400 m2); medium gap (401-600 m2); and large gap (> 600 m2). Parkia gigantocarpa had high height increment in all gap sizes during the study period, with 96.7 cm year-1 from 2005 to 2010. From 2008 to 2010 the increment in large gaps (137.9 cm year-1) was significantly different at p < 0.05 from small gaps (64.2 cm year-1). There was no mortality in large gaps in that period but in small and medium gaps the mortality rate was 16.1% and 9.7%, respectively. According to these results we can suggest the species for enrichment planting after logging, mainly in gaps larger than 600 m2.
