摘要: Abstract We determined the effects of fire history and a riparian-upland gradient on breeding bird community at Fort Bragg Military Installation in North Carolina, one largest remnant areas endangered longleaf pine (Pinus palustris) ecosystem. Study sites were classified into two treatments: fire-intense (areas experiencing growing-season burns) fire-suppressed lacking fires). Within each treatment, vegetation data recorded point-count stations positioned three distances from streamhead pocosins to characterize habitat gradient: 0, 75, ≥150 m. Total abundance species richness varied significantly along gradient, with contributing greatly avian biodiversity. Our revealed strong species, which we described terms breeding-bird assemblages. Members open assemblage (e.g., Red- cockaded Woodpecker [Picoides borea...
