La Sierra de Neiba es un área de gran relevancia para la conservación de la biodiversidad, por la particularidad de sus ecosistemas, flora y fauna. El Parque Nacional Sierra de Neiba se creó para conservar el bosque nublado latifoliado y de coníferas, su territorio está distribuido en cuatro provincias: Elías Piña, San Juan, Bahoruco e Independencia. Esta sierra ha sido deforestada por décadas, para múltiples fines (agricultura, extracción de madera preciosa, pastoreo, etc.). En el firme de la sierra se encontraba la mayor extensión de bosque nublado del país. El objetivo principal de este trabajo fue determinar cómo ha cambiado la cobertura de la tierra, comparando datos disponibles de tres períodos distintos (1996, 2003 y 2012); analizar la disminución del bosque natural, el avance de la agricultura, la ganadería y demás actividades antrópicas; inventariar la flora de esta área protegida y describir los distintos tipos de asociaciones vegetales. Las asociaciones vegetales presentes son: bosque latifoliado nublado primario, bosque latifoliado nublado secundario, bosques de pinos, bosque latifoliado en regeneración avanzada, matorrales, pastizales abiertos con árboles dispersos y vegetación de sabanas. Se registraron 1,217 especies de plantas vasculares pertenecientes a 584 géneros en 129 familias de espermatophytas. Las pteridophytas están representadas por 202 especies y 55 géneros. Se registró un endemismo de 22.69%, mientras las nativas constituyen el 67.84%. Las especies exóticas representan el 5.67%. Los principales impactos que afectan la estabilidad del bosque nublado están relacionados con la expansión de la agricultura y la ganadería.
The Sierra de Neiba is an area of great relevance for the conservation of biodiversity due to the particularity of its ecosystems, flora and fauna. The Sierra de Neiba National Park was created to preserve the broadleaf and coniferous cloud forest, its territory is distributed in four provinces: Elías Piña, San Juan, Bahoruco and Independencia. This sierra has been deforested for decades, for various purposes (agriculture, wood extraction, grazing, etc.). The largest area of cloud forest in the country was located on the top of this mountain range. The aim of this study was determine how land cover has changed, comparing data available of three different periods (1996, 2003 and 2012), how much the natural forest has declined, how far agriculture has progressed, livestock and other anthropogenic activities, inventory the flora of this protected area and describe the different types of plant associations. The plant associations present are: primary broadleaf cloudy forest, secondary broadleaf cloudy forest, pine forests, regeneration of broadleaf forest, scrub, open grasslands with scattered trees and savannah vegetation. There were 1,217 species of vascular plants belonging to 584 genera in 129 families of spermatophytes. The pteridophytas are represented by 202 species and 55 genera. An endemism of 22.69% was registered, while the natives constitute 67.84%. The aliens represent 5.67%. The main impacts that affect the stability of the cloud forest are related to the expansion of agriculture and livestock.
