Abstract
Uma das espécies potenciais para a diversificação da produção florestal não-madeireira é Euterpe precatoria Mart., cujo manejo de seus frutos para produção de polpa engloba aspectos sociais, econômicos e ecológicos concernentes à floresta. No presente estudo analisamos a densidade, estrutura, dinâmica e a estabilidade populacional desta espécie em florestas inundadas e de terra firme para avaliar o potencial ecológico de manejo. A densidade média de adultos na floresta de baixio foi de 60 indivíduos ha-1 e na terra firme de 23 indivíduos ha-1. A estrutura populacional apresentou-se em forma de J invertido. Houve uma alta produção de frutos e a sua produção por indivíduo não foi diferente entre os tipos florestais. A estabilidade populacional apresentou-se variável entre os tipos florestais e os sítios amostrados. Este estudo sugere que de modo geral Euterpe precatoria possui características ecológicas favoráveis para seu manejo sustentável, tais como alta densidade e freqüência, regeneração abundante e grande produção de frutos. Um maior potencial de manejo apresentou-se na floresta de baixio comparado ao da terra firme.
One of the species with a diversification potential for non-timber forest products is Euterpe precatoria Mart., whose fruit management for pulp production includes social, economical and ecological aspects. This study analyzes the density, structure, dynamics and stability of a population Euterpe precatoria in terra firme and inundated forests to evaluate the ecological potential of management. The mean adult density in inundated forests was 60 individuals ha-1 and 23 individuals ha-1 in terra firme forest. Population structure showed an inverse J shape. There was a high fruit production and the population stability was variable among the study sites. These ecological characteristics suggest that this species has a high management potential, such as high density and frequency, abundant regeneration and high fruit production. A greater management potential was observed in inundated forests when compared with terra firme.
