“…The selection of this particular indicator reflects its importance to the 20-25% of forest-dwelling species that are either deadwood dependant or rely on wood-roting fungi, i.e., saproxylic (Elton, 1966;Stokland and Meyeke, 2008). Several studies have shown a significant positive correlation between the amount of deadwood and species richness of saproxylic beetles (Grove, 2002;Jacobs et al, 2007;Martikainen et al, 2000;McGeoch et al, 2007;Økland et al, 1996;Similä et al, 2003;Sippola et al, 2002), wood-inhabiting fungi (Bader et al, 1995;Pentillä et al, 2004;Similä et al, 2006;Stokland et al, 2004), mammals or birds (Mac Nally et al, 2001). Nevertheless, the diversity of deadwood (type, dimension and decay stage) is also an important predictor of saproxylic beetle species richness, as it represents the diversity of possible microhabitats (Ranius and Jonsson, 2007;Siitonen, 2001;Similä et al, 2003).…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. This is an author-deposited version published in : http://oatao. Abstract• To assess the sustainability of plantation forest management we compare two types of biodiversity indicators. We used the species richness of saproxylic beetles as a case study to test the "species" and "environmental" indicator approaches. We compared single species abundance or occurrence and deadwood volume or diversity as predictor variables.• Beetles were sampled with flight interception traps in 40 Maritime pine plantation stands. The volume and diversity of deadwood was estimated with line intersect and plot sampling in the same stands. Predictive models of species richness were built with simple linear or Partial Least Square regressions.• Deadwood variables appeared to be good predictors of saproxylic beetle richness at the standscale with at least 75% of variance explained. Deadwood diversity variables consistently provided better predictive models than volume variables. The best environmental indicator was the diversity of deadwood elements larger than 15 cm in diameter.• By contrast, the use of "species variables" appeared to be less relevant. To reach the quality of prediction obtained with "environmental variables", the abundance or occurrence of 6 to 7 speciessome of which are difficult to identify -had to be used to build the indicator.

“…A well-known example is the comparison of fungal species richness and community composition in natural and managed forests. The differences in fungal assemblages are mostly explained by the differences in the dead wood profile of the forests (Penttilä et al 2004, Hottola et al 2009, Abrego & Salcedo 2013. However, the dead wood profile does not seem to be the only determining factor explaining the differences in fungal communities among different forest types.…”

Generalist species are usually widespread and abundant, and thrive in heterogeneous environments.Specialists, in turn, are generally more restricted in their range, and benefit from more stable conditions. Therefore, increasing human-induced disturbance can have more negative effects on specialist than generalist species. We assessed the specialization of 77 wood-inhabiting fungal species across seven boreal forest types and different substratum qualities. A significantly higher number of specialist species was associated with herb-rich forests and afforested fields than with managed coniferous forests and wood pastures, the number of specialists associated with natural coniferous forests being intermediate. Also, forest type specialists were indicated to be specialists for their substratum tree species as well, but specialization in substratum diameter was not connected with other kinds of specialization. Species with restricted resource or habitat preferences can less readily respond to environmental change, and therefore are more vulnerable to extinction.

“…The stand-level volume and continuity of dead wood are significant factors for saproxylic species, and particularly for threatened species (e.g. Penttilä et al 2004, Stokland and Kauserud 2004, Junninen and Kouki 2006, Hottola and Siitonen 2008. A total of 11 brook sides (about 15%) and seven controls (10%) had at least 20 m 3 ha -1 of dead wood.…”

Preservation of small habitat patches termed as "woodland key habitats" or "especially important habitats" in the Finnish Forest Act has become an integral part of biodiversityoriented forest management. Forest Act habitats belong to particular habitat types defined in the act, and they are supposed to have natural-like stand characteristics. However, very little is known about the actual stand structure in the designated habitats. Our aim was to compare stand characteristics between brook-side key habitats and comparable managed forests as controls. Seven study areas were selected from four regions across southern Finland. Within each study area ten key habitats and ten controls (140 stands) were randomly selected. Living and dead trees and cut stumps were measured in each stand within a 0.2 ha plot. The average degree of previous cutting was significantly lower whereas the volume of dead wood, volume of deciduous trees, and stand diversity were each significantly higher in key habitats than controls. The average volume of dead wood was 11.7 m 3 ha -1 in key habitats and 6.5 m 3 ha -1 in controls. However, there was considerable variation among individual stands, and a large part of key habitats could not be distinguished from randomly selected control stands with respect to stand characteristics. The preservation of natural brook channels with their immediate surroundings is undoubtedly important for maintaining aquatic and semiaquatic biodiversity. Nevertheless, when complementing the forest conservation network in the future, main emphasis in selecting potentially valuable stands should be placed on important structural features such as dead wood and old trees.
