Characterization of the floristic and parametric structure of the trees and climbing species in the forest of the Experimental Station Agroforestal Guisa (Original)

Abstract

The work was developed in the forest of the Experimental Station Guisa Agroforestal, with the aim of characterizing the floristic and parametric structure of the trees and climbing species. Five plots of 100 m² were erected, located inside 8 transects of 1 000 m², and separated at a distance of 10 m between them. To characterize the tree and scandal flora, all species were identified, the histogram of frequencies and diametric structure were made, the vines were divided into three size classes. The flora included 65 species and 59 genera, from 39 families. The trees belonged to 30 families, 40 genera and 44 species being Rubiaceae, Sapotaceae and Sapindaceae the richest families, while the bejucos belonged to 20 families, 20 genera and 21 species, constituting the family Araceae the best represented. The vines abound in smaller trees, looking for those with high capacity of growth, to reach the canopy. Only five species of vines reached more than 5 cm in diameter, being Pisonia aculeata the one of greater abundance, reason why she is the one who shows the greater dominance in the forest.
