An Evaluation of the Growing of Tectona grandis l.f Plantations Forest Unit Mayari

Abstract

The management of the forests has increased significantly in the last years, as consequence of the shortage of the wood of the natural forest and of the growing demand of forest products on the part of the population. With the objective of evaluate the growing in the plantations of Tectona grandis L. F. of the Unit Silvícola Mayarí, in the municipality II Frente, Santiago de Cuba, it was made an study in plantations of five and thirteen years, established in brown soild without carbonate where squared parcels were determined. The samples were taken completely in a random way. It was took the diameters and heights of the trees in the parcels. The dominant height was calculated of the 100 most weight trees for hectare, the volume of the hectare was inferred by de volume of the parcels of 500 m², the diameter more representative for the forest Place 1 were 18, 20 and 22 cm and for the forest Place 2 were 8 and 10 cm; the most representative heights 8, 9, 10 m for the forest Place 1 and, 3 and 6 m for the forest Place 2. The half annual increment for the diameter was of 1,4 and 1,6 cm/year and for the height of 0,70 and 0,96 m/year in the Places forest 1 and 2 respectively; the half annual increment of the volume/hectare was of 6,92 and 2,13 m³/ha/year.
