Remove coarse woody debris from forests Bird Conservation

A randomised, replicated controlled study in 1996-1999 in loblolly pine Pinus taeda stands at the Savannah River Site, South Carolina, USA (Lohr et al. 2002), found that breeding bird abundance, species richness and diversity and resident bird abundance were lower in plots where coarse woody debris was removed, compared to control plots (17-21 territories and 11-13 species/9.3 ha plots with debris removal vs. 31 territories and 20 species for control plots). Midstorey-, canopy- and cavity-nesting species such as red-headed woodpecker Melanerpes erythrocephalus, great crested flycatcher Myiarchus crinitus, eastern towhee Piplio erythrophthalmus and eastern wood-pewee Contopus virens were found at lower densities in removal plots. Pine warbler Dendroica pinus and indigo bunting Passerina cyanea were found at similar densities and summer tanagers Piranga rubra were found at higher densities. Debris removal did not appear affect winter bird community.
