Pinus caribaea

1. The richness did not vary between communities; on the other hand we found significant difference in density estimates. We found significant difference between categories for soil coverage in both sites. Grasses showed the highest coverage when compared to the other categories (Soares et al. 2015). 2. Native tree density was higher in the absence of Pinus caribaea, but presence of pine trees did not affect other native community variables. The density of individuals of native tree species ranged from 150 to 280 individuals per plot, mean (±SD) native tree density in plots with Pinus (186 ± 49) being significantly less than in plots without Pinus (219 ± 35). Native tree density decreased significantly as a function of pine tree density, from ca. 210 native plants in the absence of pines to ca. 150 plants when pine density reached 10 plants per plot.
