          Abstract

          Basados en datos de 16 inventarios forestales publicados y no publicados se analizan y discuten los patrones de estructura y diversidad de los bosques secos estacionales de dos áreas de conservación de la Reserva de Biosfera del Noroeste, Perú (el Parque Nacional Cerros de Amotape y la Zona Reservada de Tumbes). La densidad de estos bosques varía en el rango de 31 a 458. Se identificaron 34 familias, 58 géneros y 85 especies y morfoespecies leñosas. La riqueza de especies por parcela varió entre cinco y 38 especies. Estas diferencias son quizás producto de la heterogeneidad de las condiciones ambientales locales (en especial la disponibilidad de agua y otros factores edáficos). Adicionalmente se discute el efecto negativo de la ganadería y tala local sobre los estados de conservación de estos bosques. Ambos factores, naturales y antropogénicos, determinan la capacidad regenerativa y el estado actual de los mismos.

          Translated abstract

          Based on data from 16 published and unpublished forest inventory plots we analyze and discuss structural and diversity patterns in two conservation areas of the Northwestern Biosphere Reserve in Peru (Cerros de Amotape National Park and Tumbes Reserved Area). Tree density varied between 31 and 458 individuals per hectare. 34 families, 58 genera and 85 woody species and morphospecies were identified for the 16 hectares. The most species rich plot contained 38 species, while the lowest value was five species found in a plot. These differences are assumed to be the product of local environmental heterogeneity (especially water availability and edaphic factors). Additionally, agriculture and logging are identified and discussed as activities of negative influence on the conservation status of these forests. Thus, natural and human derived factors are determining the regenerative capacity and actual state of the dry forest.
