Breeding populations of the fire-adapted carabid-beetle A. quadripunctatum were found in most of the fifteen investigated burned, uncut forests, but not in any of the fifteen burned clear-cuts, although a few immigrants were found in two of them. The proportion of open-habitat carabid species progressively increased during the two first seasons after both clear-cutting and prescribed burning. These species are spring breeders in contrast to the summer-autumn breeding species found in the forest. Population of carabids, and other beetles as well, were more or less unaffected by an experimental low intensity fire. The possiblity that surviving open-habitat carabid species on burned clear-cuts prevent A. quadripunctatum from establishing successful breeding populations is discussed.
