We attempted to associate differences in faunal populations in the Tensas watershed with differences in bottomland hardwood forest area using existing data sets. The Tensas watershed was part of the original range of several species that are now absent red wolf, Florida panther, and Ivory-Billed Woodpecker The Louisiana black bear and Bachman's Warbler are also threatened with extinction. Bird surveys provided the best faunal data, and comparisons of bird populations (1) with decreases in bottomland hardwood forest over time and (2) in areas with different amounts of forest support the hypotheses that the number of forest species and the population densities of forest interior species decreased with cumulative losses of forest area We have shown the deterioration of indigenous faunal populations using existing bird surveys and qualitative data, demonstrating the utility of a cumulative impact approach at the watershed scale. By insuring the conservation of required habitats, a cumulative impact management plan would reduce further extinctions within this watershed ABSTRACTIntentamos asociar las diferencias entre las poblaclones de fauna en la cuenca de Tensas con las diferencias de extensión de áreas de bosques caducifolios de tierras bajas, usando datos existentes. La cuenca de Tensas era parte del area de distribución original de varias especies que actualmente están ausentes: lobo rojo, la puma de Florida, Pájaro Carpintero. El oso negro de Louisiana y Gorjeador de Bachman. también está en peligro de extinción. Los catastras de aves proporcionaron los mejores datos faunisticos Las comparaciones de poblaciones de aves (1) con la disminución del bosque caducifolio de tierras bajas al pasar del tiempo y (2) con áreas con diferentes superficies de este tipo de bosque apoyan la bipótesis de que el número de especies selvicolas y las densidades de población de especies del interior del bosque decrecieron junto con la disminución acumulativa en el área de bosques. Hemos señalado el deterioro de las poblaciones de fauna autoctona utilizando encuestas existentes de aves y datos cualitativos, demostrando la utilidad del enfoque del impacto acumulativo a una escala de cuencas hidrográfica Asegurando la conservación de los habitats necesarioq un plan de munejo de impacto acumulativo reducería extinciones adicionales en esta cuenca hidrográfica.
