“…However, many of the species found in thinning high-stumps in this study are probably also common in final felling high-stumps in southern Sweden. Of the 16 species tested for preferences, all but one species have been caught, with more than 10 individuals, by the present authors in other studies on final felling high-stumps when sampling by sieving of bark or when using emerging traps (Abrahamsson & Lindbladh, 2006;Lindbladh et al, 2007;Abrahamsson et al, 2008). The exception to this pattern is Placusa complanata.…”

Dead wood is regularly created during cutting operations in Fennoscandia. It has been shown that high-stumps (snags) created at final felling can be important for many saproxylic beetles, including red-listed species. However, the importance of thinning high-stumps has yet not been studied. In this study, one-and three-summer-old Norway spruce high-stumps from first thinnings, third thinnings and final fellings were sampled by bark sieving in southern Sweden. None of the 73 species found was on the red list. The thinning high-stumps did not have lower species number or species density compared with the final felling high-stumps. Tree diameter was not positively correlated with the number of species. An ordination showed that the thinning high-stumps had a different composition compared with the final felling high-stumps. Of 16 species tested for preferences, 11 showed positive or negative association for one or two of the high-stump categories. The beetle Placusa complanata was caught in thinning high-stumps only. However, most of the species found in thinning highstumps in this study are probably also common in final felling high-stumps in southern Sweden. Nevertheless, a general piece of advice based on this and other studies is that as many categories of dead wood as possible are preferable from a biodiversity point of view.

“…Saprotrophic fungi can facilitate or hamper the colonisation of stumps by many insect species and stimulate or hinder their development (Skrzecz, 1996 in pine stumps; Jonsell et al. , 2005 and Abrahamsson et al. , 2008 in spruce stumps).…”

Abstract. 1. The expanding interest in harvesting stumps for bioenergy may represent a potential threat to forest biodiversity. Whereas stumps are common in managed stands, knowledge of their associated saproxylic assemblages is still incomplete. 2. We used emergence traps to sample saproxylic beetle assemblages in oak and pine large‐diameter (>20 cm) logs and stumps and compared the assemblages from the two sources. 3. With 64–84.5% of the species pool in oak and pine, respectively, stumps definitely constituted a suitable substratum for many saproxylic species in managed forests. Higher species density suggested that stumps are more diverse habitats than logs. Stumps also host rare species and natural enemies of bark beetles. For both tree species, the assemblage composition was significantly different between logs and stumps. The dissimilarity between substratum types was predominantly due to turnover, especially for oak. 4. Our results revealed that not only do stumps constitute a substitute for some log‐dwelling species; they also provide a suitable breeding substratum for many species that may be at risk in case of massive exportation of stumps for bioenergy purposes.

“…In general, the occurrence of saproxylic beetles on LRs or dead wood is affected by substrate characteristics, including substrate metric parameters, such as bark thickness (Zhang et al 1993, Foit 2010 and diameter (Schiegg 2001, Lindhe & Lindelöw 2004, Lindhe et al 2005, Jonsell et al 2007, Maňák 2007, Jonsell 2008b, Foit 2010. Sun exposure (Jonsell et al 2004, Lindhe & Lindelöw 2004, Lindhe et al 2005, Jonsell 2008b), moisture (Wallace 1953, Larkin & Elbourn 1964, decomposition stage (Wallace 1953, Vanderwel et al 2006, Jonsell 2008b and the presence of other organisms (Jonsell et al 2005, Abrahamsson et al 2008, Weslien et al 2011) are of remarkable signifi cance for the occurrence of saproxylic beetles in various substrates. Because of these associations, known breeding substrate requirements and timing of mating and egg laying of particular BWBB species (Schwenke 1972), it is possible that the colonisation of LRs by BWBBs is infl uenced by the date of LR production (felling date).…”

Foit J., 2015. Bark-and wood-boring beetles on Scots pine logging residues from fi nal felling: effects of felling date, deposition location and diameter of logging residues. Ann. For. Res. 58(1): 67-79.Abstract. To reduce the risk of bark-and wood-boring beetle pests, the extensive removal of logging residues is conducted in forests; however, this practice can lead to a loss of saproxylic insect diversity. Thus, finding a better pest management strategy is needed and requires additional information on the actual effects of various, differently treated logging residues for pest multiplication. In the present study, a total of 2,160 fragments of Scots pine (Pinus sylvestris L.) logging residues generated during final felling in a single stand in the Drahanská Highlands in the Czech Republic were examined for bark-and wood-boring beetles. The felling occurred on four dates in 2006 (in February, May, August and November). The logging residues from each felling were left scattered on the clear-cut area or were gathered into piles. The fauna inhabiting the logging residues were investigated by peeling off the bark during the first six months of the vegetative period following the felling. The logging residues hosted species-rich assemblages of bark-and wood-boring beetles (25 species were identified). Beetle occurrence was significantly affected by felling date, logging residue type (trunk fragment or branch and branch thinner or thicker than 1 cm), diameter and the manner in which the logging residues were deposited (freely scattered, top pile layer, or bottom pile layer). The Scots pine logging residues were a substrate for the significant multiplication of several potentially significant pests (particularly, Pityogenes chalcographus [Linnaeus], Ips acuminatus [Gyllenhal] and Pityophthorus pityographus [Ratzeburg]). The results indicated that the risk of pest reproduction can be minimised by felling the trees in August (and probably also September and October). For I. acuminatus and P. pityographus, the risk can be minimised by gathering the logging residues into piles.
