SMALL SCALE CONSERVATION STATUS IN FORESTS – SOURCE OF BARK BEETLE PROBLEMS?

Keywords: spruce bark beetle, Ips typographus, hazard, selective sanitary felling, woodland key habitat, managed forest
Abstract:

Using GIS techniques, spruce bark beetle Ips typographus (L.) damage was analysed against distance from the edge of small spruce stands with strict protection regime; for reference damage nearby managed spruce stands was used. Mean volume of spruce timber, harvested with sanitary fellings was significantly higher near spruce stands with strict conservation status (14.7 ±2.1 to 17.0 ±3.8 m3/ha) than in the vicinity of managed control sites (9.9 ±0.4 to 11.5 ±0.8 m3/ha). Under endemic spruce bark beetle population levels strict conservation regime in small areas (forest woodland key habitats of average 3.7 ha size) was found to be Ips typographus hazard for adjacent spruce forests up to 450 m distance.
