Abstract
The Pine Barrens of New Jersey may be regarded as a fire-maintained subclimax. The effects of a 1963 fire on the populations of invertebrate animals of the forest floor were investigated by comparing the fauna of areas which had been burned with that of unburned areas, approximately 1 year after this fire. Both numbers of taxa and numbers of individuals were significantly less in the burned-over area. Ants appeared to be least severely affected, with 2 species appearing more abundant in the burned than in the unburned areas.
