Abstract
Miconio prasinae–Cyatheion arboreae alliance is described. Although it has five associations, we address three in this work, corresponding to immediate, secondary and early successional communities in abandoned pasture lands or crops in submountains rainforest over metamorphic rocks. The objective of this work is to study the first communities in used and abandoned fields, because they are of a great importance in the understanding of the vegetation’s evolution and for management purposes. In the submontane forest on the metamorphic complex, the destruction of mature vegetation produces important losses in climatic biodiversity and transcendental changes in ecosystem composition. The change in soil use, especially the transformation to pastureland, has favored the development of herbaceous and shrubby plant communities. This study is not only of practical relevance in describing the associations of the pine forests the plant associations and the study of the ecological conditions in which they develop, but its results can be used as a working tool in the environmental management and silviculture for the restoration of degraded areas. The study of diverse Cuban vegetation types suggests that the methodology of Zurich Montpellier’s school is more effective as compared to other authors because its syntaxa is good to recognize and is able to transform in a forest typology. The main species are pioneers heliophilous with a type of r selection.
Highlights
There are some works about succession in Cuban forest [8, 15, 16]; there was not enough those made on mountain areas [18].In submountain rainforest over metamorphic complex [18] destruction of maturity vegetation produce important loses in climacic biodiversity and transcendental changes in ecosystemic composition
The objective of this work is to study the evolution of first communities in used and abandoned fields in the submountain rainforest ecotopes over metamorphic complex in rainiest areas of Cuban archipelago
Geology is represented by Sierra del Purial Formation [7], composed by different kind of schist, intermediate tuffs between other rocks
Summary
There are some works about succession in Cuban forest [8, 15, 16]; there was not enough those made on mountain areas [18]. In submountain rainforest over metamorphic complex [18] destruction of maturity vegetation produce important loses in climacic biodiversity and transcendental changes in ecosystemic composition. In a similar ecosystem Caluff [4] and Sanchez-Ruiz [22, 23] had quantify heavy losses of pteridological and spiders diversity with the change of use of soils, getting the maximum with pasturelands transformation. The objective of this work is to study the evolution of first communities in used and abandoned fields in the submountain rainforest ecotopes over metamorphic complex in rainiest areas of Cuban archipelago
