GONZALEZ DIAZ, Seidel et al. THE DEFORESTATION OF THE EVERGREEN FOREST IN SOROA CANDELARIA, ARTEMISA, CUBA. Rev. Fac. Nac. Agron. Medellín [online]. 2011, vol.64, n.1, pp.5937-5947. ISSN 0304-2847.

The negative man's action on the forest has impacted in the disappearance of many species that belong to the evergreen forest. The present investigation demonstrate the grade of interference on the forest in the community of Soroa, Candelaria, Artemisa, Cuba and the existent potentialities in the area to revert this situation, from an economic, social and environmental perspective. The objective is to evaluate the influence of the proximity to community in the affectation of species to the evergreen forest in Soroa . For this purpose, 20 parcels were selected at random being also measured the distance to the community and the diameter of trees and strubs. A binary logistical regression was applied to estimate the probability of finding a superior proportion to 25% of the characteristic species of the area, the indexes of diversity and equity were calculated, in the arboreal and strub strata, which were compared by means of the range test with signs of Wilcoxon. Two groups were formed, one of them consists of a distance to the community inferior to 2.5 km and the otherone is bigger or similar to the distance of 2.5 km. A test U of Mann Whitney was applied to compare the diameters in both groups, being demonstrated that the anthropic activity is one of the causes that impact on the deforestation of the evergreen forest in the mountain of Candelaria.
