The multiple dimensions of forest biodiversity as a starting point for sustainable management

ests cover almost 40% of the European Union territory [1], and, with 75 forest types [2] and 81 habitats (Directive 43/92/CE), are crucial for the conservation of biodiversity in Europe. One quarter of European forests are protected, but only about 1% is left unharvested [1].

These figures underline why the maintenance of forest biodiversity in the European Union is based on the concept of sustainable forest management (SFM). Despite this, about 80% of the forest habitat types are in an unfavourable conservation status, and forest management is reported as their main pressure [3].

The existing SFM indicators for the biodiversity sustainability of forest management either account only for trees, or are indirect biodiversity proxies, often not tested or vaguely defined. This crucial gap stems from the lack of broad scale forest biodiversity data, with multi-taxon biodiversity usually not sampled during national forest inventories due to money and time constraints.

Recently, several groups of scientists from research institutions across Europe took up the challenge of multi-taxon field sampling through local or regional projects aimed at understanding the effects of forest management on overall ecosystem biodiversity. The BOTTOMS-UP platform of European forest biodiversity encompasses about 3,000 plots across 13 forest categories [2] and 13 European countries. For each plot, information on at least three taxonomic groups are available, besides spatial coordinates, individual tree measures, and information on forest management [4].

This effort will be used as a means and stimulus for upscaling ideas and actions performed at the local level on the effects of different management regimes and of specific good practices on several taxonomic groups, and on the identification of direct biodiversity indicators of management sustainability.
