“…The great majority of our surveyed stumps were man-made, which was also the case in general for stumps in the study landscape. At a smaller (dead-wood item) scale, Jonsell et al (2004) and Pasanen et al (2018) also found only minor differences in species richness between naturally formed and cut dead wood. However, they revealed differences in beetle species composition between dead-wood categories (Jonsell et al 2004), and reported that the variation in fungal species composition among dead-wood items was higher in naturally formed dead wood (Pasanen et al 2018), which is not consistent with the outcomes from our analyses (Fig.…”

The evolutionary species pool concept does not explain occurrence patterns of dead-wood-dependent organisms: implications for logging residue extraction

Emulation of natural disturbances is often regarded as a key measure to make forestry biodiversity-oriented. Consequently, extraction of logging residues is assumed to have little negative effect in comparison to extraction of dead wood mainly formed at natural disturbances. This is consistent with the evolutionary species pool hypothesis, which suggests that most species are evolutionary adapted to the naturally most abundant habitats. We tested this hypothesis for dead-wood-dependent macrofungi, lichens, and beetles in a boreal forest landscape in central Sweden, assuming that species are adapted to conditions similar to today’s unmanaged forest. No occurrence patterns, for the species groups which we investigated, were consistent with the hypothesis. Overall, stumps and snags had the highest habitat quality (measured as average population density with equal weight given to each species) and fine woody debris the lowest, which was unexpected, since stumps were the rarest dead-wood type in unmanaged forest. We conclude that the evolutionary species pool concept did not explain patterns of species’ occurrences, and for two reasons, the concept is not reliable as a general rule of thumb: (1) what constitute habitats harbouring different species communities can only be understood from habitat-specific studies and (2) the suitability of habitats is affected by their biophysical characteristics. Thus, emulation of natural disturbances may promote biodiversity, but empirical studies are needed for each habitat to understand how natural disturbances should be emulated. We also conclude that stump extraction for bioenergy is associated with larger risks for biodiversity than fine woody debris extraction.

“…Many saproxylic species have specific demands regarding tree species, size of dead‐wood debris, decay stage, and type (snag or log) of dead wood (Stokland et al, ). As dead wood in the study area is enriched mostly during harvesting (Doerfler et al, ), it cannot be ensured that the creation of dead wood follows specific patterns needed to enhance specific, especially endangered, species (Pasanen et al, ). By applying the same management regime in the entire study area, plots tend to become more and more similar, which could possibly reduce overall diversity as a result of decreasing beta diversity.…”

Aim European temperate forests have lost dead wood and the associated biodiversity owing to intensive management over centuries. Nowadays, some of these forests are being restored by enrichment with dead wood, but mostly only at stand scales. Here, we investigated effects of a seminal dead‐wood enrichment strategy on saproxylic organisms at the landscape scale. Location Temperate European beech forest in southern Germany. Methods In a before–after control–impact design, we compared assemblages and gamma diversities of saproxylic organisms in strictly protected old‐growth forest areas (reserves) and historically moderately and intensively managed forest areas before and a decade after starting a landscape‐wide strategy of dead‐wood enrichment. Results Before enrichment with dead wood, the gamma diversity of saproxylic organisms in historically intensively managed forest stands was significantly lower than in reserves and historically moderately managed forest stands; this difference disappeared after 10 years of dead‐wood enrichment. The species composition of beetles in forest stands of the three historical management intensities differed before the enrichment strategy, but a decade thereafter, the species compositions of previously intensively logged and forest reserve plots were similar. However, the differences in fungal species composition between historical management categories before and after 10 years of enrichment persisted. Main conclusions Our results demonstrate that intentional enrichment of dead wood at the landscape scale is a powerful tool for rapidly restoring saproxylic beetle communities and for restoring wood‐inhabiting fungal communities, which need longer than a decade for complete restoration. We propose that a strategy of area‐wide active restoration combined with some permanent strict refuges is a promising means of promoting the biodiversity of age‐long intensively managed Central European beech forests.

Conservation management for fungi has lagged behind animal and plant conservation, and remains largely restricted to protecting known locations of few conspicuous threatened species. We used Estonian polypores as an example of how conservation options can be systematically screened, based on the Red List of threatened species and in co-operation with practitioners. For a total of 61 species, we identified a broad range of management options representing diverse approaches (site protection; prescriptions of land use; protection of individuals; special management; protection via umbrella species). The results demonstrated the merits of systematic and multi-disciplinary assessments for fungal conservation and setting related research priorities. Our assessment also supported a theoretical expectation that some ecosystem conservation strategies should be explicitly designed based on functionally important groups of fungi. The advancement of fungal conservation appears largely dependent on co-operation between mycologists, conservationists and managers. Eesti metsade seenestiku looduskaitsevõtted torikseente näitel Seenestiku looduskaitseks kasutatav võttestik on märksa halvemini välja arendatud kui loomade ja taimede puhul ning hõlmab peamiselt silmatorkavate ohustatud liikide leiukohtade kaitset. Töös kirjeldatakse Eesti torikseente näitel, kuidas sobivaid looduskaitsevõtteid saab süstemaatiliselt valida – lähtuvalt ohustatud liikide nimestikust ja koostöös looduskaitsepraktikutega. Kokku eristati 61 ohustatud torikseeneliigi kaitseks lai valik võtteid, mis hõlmasid erinevaid võimalusi alade kaitseks, üldisi maakasutusjuhiseid, isendite kaitset, intensiivseid kaitsevõtteid ja kaitset teiste liikide (katusliikide) kaudu.Tulemused näitavad süstemaatilise ja multidistsiplinaarse analüüsi efektiivsust seente kaitse ja sellega seotud uuringute planeerimisel. Analüüs kinnitas ka teoreetilist, torikseente funktsionaalsest tähtsusest lähtuvat eeldust, et mõned ökosüsteemide kaitse võttestikud tuleks kujundada just seente ökoloogiast lähtuvalt. Seenestiku looduskaitse peamine edenemistingimus paistab niisiis olevat koostöö mükoloogide, looduskaitseteadlaste ja -praktikute vahel.
