“…Reference values for very large trees are difficult to find because the diameter limit defining a very large tree is highly variable among studies, from 50 cm (Burrascano et al, 2013) to more than 100 cm (see, for example, the so-called IBP evaluation tool by Larrieu and Gonin, 2008). If we convert results expressed in basal area (assuming 80 or 90 cm as mean dbh for a very large tree), Grosso (2012) and Benoît and Augé (2014) found values ranging from 5 to 10 trees ha À1 with the same counting limit in mature forests in the French Alps.…”

“…According to maturity evaluation tools developed after the compilation of numerous local studies by private forest managers (Larrieu and Gonin, 2008) or by the French WWF (Rossi and Vallauri, 2013), such a value is the best score for a ''maturity'' indicator. In similar ecological contexts, i.e., French mountain forests with soils of medium to high fertility, local studies have found values comparable to ours: Pernot et al (2013), considering six distinct forest sites in French mountain forests found an average total volume of deadwood of 58 m 3 ha À1 in unmanaged areas.…”

“…TreMs are considered as relevant surrogates of direct biodiversity measures (Winter & Möller ), particularly for saproxylic beetles (Bouget et al . ; Bouget, Larrieu & Brin ), and are already integrated into some practical biodiversity assessment tools used by forest managers (Larrieu & Gonin ). In addition, conservation of biodiversity in managed forests can be improved by protecting high biodiversity value trees such as trees bearing TreMs and dead trees from harvesting.…”

“…The role of deadwood as a habitat for many insects, fungi or lichen species has been recognized for decades (Speight 1989;Bobiec, Gutowski & Audenslayer 2005;M€ uller & B€ utler 2010;Stokland, Siitonen & Fjonsson 2012;Gossner et al 2013;Lachat et al 2013;Seibold et al 2015). More recently, research has focused on tree-biodiversity measures (Winter & M€ oller 2008), particularly for saproxylic beetles Bouget, Larrieu & Brin 2014), and are already integrated into some practical biodiversity assessment tools used by forest managers (Larrieu & Gonin 2008). In addition, conservation of biodiversity in managed forests can be improved by protecting high biodiversity value trees such as trees bearing TreMs and dead trees from harvesting.…”

“…Des relations non liné aires existent entre ces attributs et l'âge du peuplement ; et un seuil d'abondance des attributs de maturité est observé dans des peuplements en é volution naturelle ayant dé passé la moitié de la longé vité de l'essence [17][18][19]. En forêt exploité e, ces relations ne sont pas toujours vé rifié es, car l'application d'un diamè tre d'exploitabilité souvent trè s faible par rapport au potentiel de croissance de l'essence et le martelage visant à pré server la qualité technologique des bois ré duisent l'occurrence de l'ensemble des attributs [20,21].…”
