Abstract
The natural regeneration in coniferous forests is a method of possible application in de silvicultural context of Cuba, where the stands renovation is made by planting. In particular case of Caribbean pine (Pinus caribaea var. caribaea) the natural regeneration there is not applied because the abundant seeds sources and easy management in nursery. However, one deep analysis shows the specie possibilities for natural reproduction and economics and ecological advantages by the high numbers of plants obtained by area. Besides, the reductions in environment impacts to be considered above all in sites with pour nutrient content.
In this paper were assessed a brief economic analysis of this method derived of the natural regeneration trials located in the Gilberto Leon Forest District that belong to Minas Forest Enterprise of Pinar del Río.
Here, we contrasted some areas regenerated by natural reproduction with artificial plantations since establishment until the first clear felling in relation to silvicultural establishment costs and timber costs as a function of different rotations by the possible elongation of the rotation in naturally regenerated way.
