Comparison of Bird Communities in Burned and Salvage-Logged, Clearcut, andForested Florida Sand Pine Scrub

摘要

The authors hypothesized that similar bird assemblages will occur in like-structured habitat that results from both clearcutting and high-intensity wildfire followed by salvage logging. To test this, the authors compared bird communities of sand pine scrub in mature forest and three disturbance treatments (1) high-intensity wildife, salvage logged, and naturally regenerated, (2) clearcut, roller chopped, and broadcast seeded, and (3) clearcut and bracke-seeded. The authors analyzed communities based on residency status and nesting guilds. Migratory breeding birds were nearly restricted to mature forest. Bird communities of mature forest were significantly more species rich and diverse than those of disturbance treatments in spring. However, species richness and diversity of migratory winter residents did not differ among treatments, indicating that they are habitat-structure generalists on their wintering
