Ecological traps and habitat loss, stump extraction and its effects on saproxylic beetles

Victorsson, Jonas; Jonsell, Mats

Abstract

Stump extraction reduced the P. abies stump volume by 76%. The concomitant decrease in beetle community abundance was 70%, a decrease from 9109 to 2692 beetles per hectare. A conservative estimate is that between 5.2% and 23.1% of the beetles "produced" at the stump extraction site were killed at stump pile removal. Our results indicated that the stump storage piles were a severe ecological trap for four individual species. However, a lower community density of beetles in stump storage piles compared to surrounding extraction clear-cuts, indicate that stump storage piles did not constitute a community-wide ecological trap.
