“…The number of releases can be indicative of both human-induced but also natural disturbances, and the reduced number of stands, this makes difficult to find differences between them. In any case, the links between the number of releases, stand attributes and deadwood evidence that past management leaves an imprint on forest structure and composition [44][45][46]. In terms of structure, more heavily exploited stands, primarily by the removal of large trees, reduces structural diversity and predisposes stands to drought-induced dieback [15].…”

“…However, it is important to note that the studied forests are not managed nowadays [15] and that current stand vigor is an important factor determining the accumulation of deadwood in the understory [82]. It is expected that large trees are more prone to offer suitable microhabitats for biodiversity maintenance [44]; thus, further studies should deepen knowledge of the differences in deadwood quantity and quality between silver fir forests with different management histories and levels of vigor.…”

“…However, old-growth, well-preserved forests are scarce in Europe [43], and this situation is also evident in the Pyrenees [42]. Old-growth forests represent remnants of past forest conditions and can be used as models guiding conservation and management strategies for preserving multifunctional forests [44]. For example, unmanaged and old-growth forests are structurally and compositionally more diverse than managed ones [45], despite the fact that both types of forests can have similar amounts of living biomass [46,47].…”

Recent drought-induced dieback alters forest dynamics, which are also shaped by past management. In western Pyrenean silver fir (Abies alba) stands, dieback concurs in space and time with the legacies of past management, but the impacts on forest growth, structure and composition are unknown. We aim to disentangle how dieback interacts with the legacies of past human use and modulates the recent dynamics of silver fir forests. To this end, we sampled eleven silver fir forests across wide climatic gradients and included declining and non-declining sites. We measured radial growth, structure, composition, understory cover and type and amount of deadwood. Silver fir growth declines in response to late-summer drought. In declining sites, most defoliated stands showed the lowest silver fir density and were those where growth depended more on water availability. Tree death enhanced the cover of dominant understory plants such as Buxus sempervirens. Past management activities leave an imprint in the growth of silver fir, such as releases due to past logging, but also affect the number of stumps and snags and the current tree density. A more extensive monitoring will be required to fully disentangle the multiple influences of past management legacies and current climate change on forest dynamics.

Assessing forest biodiversity, naturalness and old-growth status (B-N-OG) is crucial for supporting sustainable forest planning, yet comprehensive monitoring networks specifically designed for such purposes are lacking in many countries. National Forest Inventories (NFIs) are the official source of statistics on status and trends of forests. While initially designed for wood production assessment, NFI data may be pivotal for ecological forest monitoring, thanks to their robust sampling protocols—enabling statistical inference—and regular field campaigns that ensure continuous information updates. As a consequence, in this study we explore the potential of NFIs for estimating B-N-OG indexes, aiming to establish compatible, scientifically relevant, and cost-effective indicators using existing NFI data at a European level. Based on data from the 2005 Italian NFI collected from 6563 plots, 18 indicators were selected following previous experiences and then used to estimate B-N-OG aggregated indexes. Relationships between the 18 indicators and the three indexes were investigated, along with comparisons of their relationships relative to forest type categories, management types and protected versus non-protected areas. Results confirm that NFI data offer valuable insights into specific B-N-OG indexes, especially concerning forest structure and deadwood. Moreover, the indexes contribute to developing meaningful relationships across geographic regions, forest categories and types of management. However, limitations in NFI field protocols are evident, as they are not explicitly designed for certain indicators. The study suggests the potential for NFIs to evolve into accessible, harmonized European reference networks for B-N-OG assessment for better supporting sustainable forest management, planning and conservation decisions related to forest ecosystems.
