Nerea Abrego from the University of Helsinki presented research on reintroducing threatened wood-inhabiting fungal species via inoculation. The study demonstrated that inoculation of selected red-listed fungal species into logs was an effective reintroduction method, as all species successfully established as mycelia and three produced fruit-bodies. Success was greater when strains were inoculated into early-decay logs. Inoculation provides an effective and low-cost tool for fungal reintroductions if preceded by risk assessment and using local source populations, and is meant to complement habitat restoration. The results suggest reintroductions of threatened fungi via inoculation can importantly support forest conservation efforts.

Thus far, this option has however not been investigated for fungi other than lichens. A large fraction of wood-inhabiting fungal species have declined because of forest loss and fragmentation, in addition to a decrease in dead wood. Here, we show the results from an experiment carried out in southern Finland, which demonstrates that inoculation is an effective method for reintroducing threatened wood- inhabiting fungi. All selected red-listed fungal species successfully established in the inoculated logs as mycelia, and three out of the seven produced fruit-bodies. Success rate was greater when the strains were inoculated in early-decay logs, including species that usually fruit in late decay stages. Inoculation can provide an effective tool for reintroducing fungal species, as the source populations remain intact and it is possible to produce massive amounts of inoculation-units with relatively low cost. Reintroductions of fungi should however be preceded by a risk assessment of the species to be reintroduced, by using source populations from nearby localities, and they should be considered complementary to the primary target of increasing the amount of their habitat. Our results suggest that the reintroductions of threatened fungi via inoculation in combination with other conservation measures can have important bearings for forest conservation and restoration.
