Abstract
Summary Four Carabus species with different habitat requirements were sampled by pitfall trapping in fir forests of southern France managed using clearcutting or selection systems. Three stages of clearcutting management system were considered: clearcut, intermediate thicket, mature. The study showed that individuals of one forest generalist species were less abundant in thicket stands, whereas individuals of one forest specialist were less abundant in clearcut stands. However, although some stages of the clearcutting system were found to be unfavourable to some Carabus, comparable levels of carabid abundance were found in stands managed using clearcutting or selection systems. In continuous forested landscapes, the two management systems that we studied may thus have equal impacts on carabid abundance. Our results imply dynamic processes of exchanges between plots and their surroundings, and rapid re-colonization of previously unfavourable areas by Carabus species.
