Gongalsky, K. B., Midtgaard, F. & Overgaard, H. J. 2006: Effects of prescribed forest burning on carabid beetles (Coleoptera: Carabidae): a case study in southeastern Norway. — Entomol. Fennica 17: 325–333.
The influence of prescribed burning on ground beetleswas studied in a single 12-ha stand that was partially clear-cut, selectively-cut and retained (= standing forest), and was compared to an unburned stand in 2002 in SE Norway. Thirty-two species were collected using Barber pitfall traps. Carabids were more numerous and more diverse in the burned area, compared to the unburned forest. Overall abundance was highest in the selectively-cut treatment, followed by the clear-cut and standing forest. Species diversity tended to increase in the sequence unburned forest – burned standing forest – burned selectively-cut – burned clearcut. Species composition differed little between the burned treatments. Pterostichus adstrictus, a species associated with open habitats and which frequently colonizes burned areas, was the most abundant species collected. It was most common in the burned area, particularly in the selectively-cut treatment. Our results suggest that burning of a single stand may support some carabid species, even endangered ones, although larger forest fires are probably more effective for conservation purposes.
