Composição botânica na área de influência da copa de Spondias mombin L. disperso em pastagens no assentamento Belo Horizonte I, São Domingos do Araguaia-PA

Abstract

The natural regeneration of tree species in pastures is of great importance for the diversification of the production system of family farmers, because it can be a sustainable alternative in the formation process of silvopastoral systems (SPS) of the type "dispersed trees in pasture". This study recorded the invasive tree species from under canopy the Spondias mombin L. and compared the richness and frequency of those species in open pastures. The work was carried out in a family farmers property the rural settlement "Belo Horizonte I", located in the municipality of São Domingos do Araguaia-PA. A pared design was used, with a 4m2 control plot in open pasture for each equally sized plot under the canopy of the yellow mombin. The taperebá canopy provided a microclimate favorable to natural regeneration of tree species: guava (Psidium guajava L.), bastard cedar (Guazuma ulmifolia Lamarck) and S. mombim. On open pasture area, outside the area of influence of canopy no tree species in young phase or seedlings were found. The maintenance of yellow mombin trees scattered in grazing areas is an appropriate strategy to accelerate the enrichment of natural vegetation in SPS.
