|a We determined the effects of fire history and a riparian-upland gradient on the breeding bird community at Fort Bragg Military Installation in North Carolina, one of the largest remnant areas of the endangered longleaf pine (Pinus palustris) ecosystem. Study sites were classified into two treatments: fire-intense (areas experiencing growing-season burns) and fire-suppressed (areas lacking fires). Within each treatment, bird and vegetation data were recorded at point-count stations positioned at three distances from streamhead pocosins to characterize the riparian-upland habitat gradient: 0, 75, and ≥150 m. Total bird abundance and species richness varied significantly along the riparian-upland gradient, with pocosins contributing greatly to avian biodiversity. Our data revealed strong effects of fire history and riparian-upland gradient on bird species, which we described in terms of breeding-bird assemblages. Members of the open longleaf assemblage (e.g., Red-cockaded Woodpecker [Picoides borealis], Bachman's Sparrow [Aimophila aestivalis]) were most common in fire-intense areas and at upland locations. Members of the fire-suppressed assemblage (e.g., Wood Thrush [Hylocichla mustelina], Ovenbird [Seiurus aurocapilla]) were confined to pocosins in fire-intense areas, but became more abundant in fire-suppressed areas. Members of the pocosin assemblage (e.g., Eastern Towhee [Pipilo erythropthalamus], Common Yellowthroat [Geothlypis trichas]) were largely confined to pocosins and, in some cases, were most abundant in fire-intense pocosins. Fire suppression increased structural diversity of vegetation and promoted one breeding-bird assemblage (fire-suppressed), but at the expense of two others (open longleaf, pocosin). Continued management of Fort Bragg to promote longleaf pine restoration is essential for supporting conservation of the open-longleaf bird assemblage; in addition, it will benefit the pocosin assemblage. /// Determinamos los efectos de la historia del fuego y de un gradiente entre áres ribereñas y tierras altas en la comunidad de aves que crían en la Instalación Militar de Fort Bragg en North Carolina, una de las áreas remanentes más grandes del ecosistema amenazado de Pinus palustris. Los sitios de estudio fueron clasificados en dos tratamientos: con fuego intenso (áreas quemadas durante la estación de crecimiento) y con supresión de fuego (áreas sin fuego). Para cada tratamiento se registraron datos de las aves y la vegetación en estaciones de conteo ubicadas a tres distancias (0, 75, y ≥150 m) desde los extremos de los cenagales para caracterizar el gradiente ambiental entre el sector ribereño y las tierras altas. La abundancia total de aves y la riqueza de especies variaron significativamente a lo largo de este gradiente, con una alta contribución de los cenagales a la diversidad de aves. Nuestros datos revelaron la existencia de fuertes efectos de la historia del fuego y de los gradientes ambientales sobre las especies de aves, los cuales describimos en términos de los ensambles de aves reproductivas. Los miembros del ensamble de las áreas abiertas de P. palustris (e.g., Picoides borealis, Aimophila aestivalis) fueron más comunes en las áreas con fuego intenso y en las zonas de tierras altas. Los miembros del ensamble de las zonas sin fuego (e.g., Hylocichla mustelina, Seiurus aurocapilla) estuvieron restringidos a los cenagales en las áreas con fuego intenso, pero fueron más abundantes en las áreas sin fuego. Los miembros del ensamble de los cenagales (e.g., Pipilo erythropthalamus, Geothlypis trichas) estuvieron principalmente restringidos a los cenagales y en algunos casos fueron más abundantes en cenagales con fuego intenso. La supresión del fuego incrementó la diversidad estructural de la vegetación y promovió un ensamble de aves reproductivas (el de las zonas sin fuego), pero a costa de otros dos ensambles (el de áreas abiertas de P. palustris y el de los cenagales). Es esencial continuar con el manejo de Fort Bragg para promover la restauración de áreas de P. palustris para apoyar la conservación del ensamble de aves de este ecosistema. Adicionalmente, esto beneficiará el ensamble de aves de los cenagales.
