Effects of Forest Management Practices on Terrestrial Coleopteran Assemblages in Sand Pine Scrub

C. Greenberg,Michael C. Thomas

Published 1995 in Florida Entomologist

ABSTRACT

Coleopteran assemblages were sampled monthly for one year using pitfall traps in replicated sites of three 5- to 7-year-old disturbance treatments and mature forested sand pine scrub in the Ocala National Forest, Marion County, Florida. Disturbance treatments were (1) burning at high-intensity and salvage-logging; (2) clearcutting, roller-chopping and broadcast seeding, and; (3) clearcutting and bracke-seeding. Community similarity of coleopterans was high. No differences in species richness, diversity, density, or evenness were detected. Of 40 species captured, only seven were common (n > 50). Predaceous beetles were numerically dominant followed by scavengers. Few xylophagous or herbivorous coleopterans were captured, probably due to trap bias. Peaks of annual above-ground terrestrial activity varied among species. An absence of differences among treatments may reflect similar plant communities or structural habitat features. Additionally, a dearth of mature forest specialists might be predicted in systems where mature forest was historically rare due to large-scale, high-intensity, and low-frequency wildfire.
