Structure, distribution and conservation status of the Prosopis flexuosa woodlands in the Bolsón de Fiambalá (Catamarca). The Prosopis flexuosa woodlands have historically allowed the survival and development of productive oasis at the foot of the Andes mountains, through the use of their forest resources. Current regulations state that the use of these resources depends on the zoning of forests. However, knowledge of dryland forests is incomplete. Our aim were to determine the distribution, structure, preservation and growth of these woodlands. Woodland units were identified by supervised classification of images. Population studies of P. flexuosa were performed allometric variables were measured and applied traditional dendrochronological techniques. Two woodland types were distinguished: dense forest with greatest total coverage (39%) and sparse forest (21%). Basal diameter structures were similar, however, in the dense forest were greater overall height, the amount of timber trees and basal area. In both forests, was similarly use and conservation status. The differences between forests can be explained by the position of the forest on the underground aquifer and soil type. The conservation and controlled use of these resources is a contribution to mitigating climate change because Prosopis woodlands are the main reservoir of C in desert. Los bosques de Prosopis flexuosa han permitido históricamente la subsistencia y desarrollo de los oasis productivos al pie de la Cordillera de Los Andes, mediante el uso de sus recursos forestales. La normativa actual determina que la utilización de estos recursos dependa del ordenamiento territorial de los bosques. Sin embargo, el conocimiento de los bosques de zonas áridas es incompleto. Nos propusimos determinar: distribución, estructura actual, estado de conservación y crecimiento leñoso de los algarrobales del Bolsón de Fiambalá. Se identificaron unidades boscosas mediante la clasificación supervisada de imágenes. Se realizaron estudios poblacionales de P. flexuosa, se midieron variables alométricas y se aplicaron técnicas dendrocronológicas tradicionales. Se distinguieron dos tipos de bosque: denso con mayor cobertura total (39 %) y ralo (21 %). Las estructuras de diámetro fueron similares, sin embargo fue mayor la altura total, la cantidad de árboles maderables y el área basal en el bosque denso. Fue similar el grado de utilización y el estado de conservación. Las diferencias entre los bosques pueden explicarse por la posición del bosque relativa al acuífero subterráneo y al tipo de suelo. La conservación y utilización controlada de estos recursos, constituye un aporte a la mitigación del cambio climático ya que los algarrobales constituyen el principal reservorio de C en los sistemas desérticos.
