Sierra Maestra¹s vegetations belts and priority species for reforestation Sierra Maestra¹s vegetations belts and priority species for reforestation

Abstract

The Sierra Maestra is characterized by the large number of forest formations present in it, a consequence of the diversity of ecological conditions. Although these formations are largely altered, there is still a good representation of the composition of the original forests. This study aims to contribute to the conservation of this important natural heritage, through restoration, rehabilitation and/or enrichment actions, with the species considered as priorities. These priorities were determined based on 180 phytocenological inventories that inventoried a total of 100 species present in the four vegetation levels found, following the altitudinal zoning proposed by several authors. These levels are: 1. Level of semi-deciduous forests and scrublands (Wetland zone, semi-deciduous microphyllous forests and scrublands and Semi-deciduous mesophyllous forest zone); 2. Evergreen forest level; 3. Montane rainforest level and 4. Cloud forest level. The selection of species is based on their high presence and abundance dominance. A characterization of the ecological factors present in the different ecotopes is presented, together with a map showing the distribution of vegetation belts. The criteria raised can be reflected in the strategies to be followed for forest management for conservation purposes in the Sierra Maestra.
