SUMMARY:

The present work aims to evaluate the silvicultural characteristics of seedlings of Schizolobium parahyba var. amazonicum (Huber ex Ducke) Barneby (paricá), produced in a nursery and planted in gaps caused by low-impact logging, as an alternative for forest enrichment after logging. The experimental area is 700.00 ha of dense rainforest, in the municipality of Paragominas, in the State of Pará. Survival rates, IPAH - Annual Periodic Increment in Height, IPADAP - Periodic Annual Increment in Diameter, IMAH - Average Annual Increment in Height and IMADAP - Average Annual Increment in Diameter and the correlation between the classes of gaps and their respective increments to study the possibility of using the species in enrichment of post-exploitation gaps. For field data collection, 245 clearings were selected, located in the forestry area of the company Cikel Brasil Verde Madeiras Ltda., Fazenda Rio Capim, in work units 7 and 8. Regarding the seedlings produced, approximately 1,088 were planted. seedlings of Schizolobium parahyba var amazonicum (Huber ex Ducke) Barneby (paricá), in 2005, the same period in which the first evaluation of survival and growth rates of seedlings was carried out. Other evaluations were carried out in 2006, 2008, 2010 and 2018. The survival of the species was negatively influenced by the lack of application of silvicultural treatments from 2008 onwards. height and diameter. The size of the gap classes will not contribute to a significant increase in height and diameter increments. Thus, the results showed that, based on the growth and survival of Schizolobium parahyba var amazonicum (Huber ex Ducke) Barneby, it can be concluded that the species is recommended for enrichment in gaps, if silvicultural treatments are applied to eliminate competition, where the classes of gaps will have little influence on the increase in height and diameter at Fazenda Rio Capim, Paragominas, Pará.
