Leurs attributs leur confèrent un fort potentiel d’accueil de biodiversité, particulièrement saproxylique. Depuis une quinzaine d’années, elles font l’objet d’inventaires, d’évaluations ou de cartographies sur une grande partie du territoire métropolitain. De nombreux projets sont en cours ou émergent, portés par diverses structures (parcs nationaux ou régionaux, réserves naturelles, Office national des forêts, conservatoires d’espaces naturels, conservatoires botaniques…). Les protocoles varient d’un projet à l’autre mais certains attributs sont relevés de façon quasi systématique. Les objectifs affichés diffèrent mais sont axés autour de quelques grands thèmes : prise en compte des forêts anciennes et matures dans les chartes ou les plans de gestion des aires protégées, dans les documents de gestion durable, dans l’élaboration de trames de vieux bois pertinentes, dans des projets de recherche visant à améliorer la connaissance de leur biodiversité ou de leur fonctionnement, dans des actions de communication et de sensibilisation en faveur de leur préservation.

Titre : How much does it take to be old? Modelling the time since the last harvesting to infer the distribution of overmature forests in France Type de document : Imprimé Auteurs : Lucie Thompson ; Eugénie Cateau ; Nicolas Debaive ; Frédéric Bray ; André Torre ; Patrick Vallet ; Yohann Paillet Année de publication : 2022 Article en page(s) : 200-213 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Forêts (habitat) Résumé : Aim: The distribution of overmature forests in metropolitan France is poorly known, with only a few well-studied prominent sites, and has never been evaluated countrywide. Here, we modelled French forest reserves' time since the last harvesting operation—a proxy for forest maturity—then inferred the current statistical distribution of overmature forests (i.e., forests over 50 years without harvesting) in France. Location: Metropolitan France. Methods: We used inventories from forest reserves and managed forests to calibrate a generalised linear mixed model explaining the time since the last harvesting with selected structural attributes and environmental variables. We then projected this model on the independent National Forest Inventory dataset. We thus obtained an updated estimation of the proportion and a rough distribution of overmature forest stands in metropolitan France. Results: We found that high basal area of very large trees, high volumes of standing and downed deadwood, high diversity of tree-related microhabitats and more marginally diversity of decay stages best characterised the time since the last harvesting. Volumes of stumps and high density of coppices translating legacy of past forest management also distinguished more overmature plots. Our projection yielded an estimated 3% of French forests over 50 years without harvesting mostly located in more inaccessible areas (i.e., mountainous areas). Main conclusions: Our study showed that the time since the last harvesting could be derived from a combination of key structural attributes characterising overmature temperate forests. It gives the first robust statistical estimate of the proportion of overmature forests in France and may serve to report on their status. Our method could be extended in countries with accessible National Forest Inventory and calibration data, thus producing indicators at an international level.

Titre : Nothing else matters? Tree diameter and living status have more effects than biogeoclimatic context on microhabitat number and occurrence : An analysis in French forest reserves Type de document : Imprimé Auteurs : Yohann Paillet ; Nicolas Debaive ; Frédéric Archaux ; Eugénie Cateau ; Olivier Gilg ; Eric Guilbert Année de publication : 2019 Article en page(s) : e0216500 Langues : Français (fre) Catégories : [CBNPMP-Thématique] Forêts (habitat)
[CBNPMP-Thématique] BiodiversitéRésumé : Managing forests to preserve biodiversity requires a good knowledge not only of the factors driving its dynamics but also of the structural elements that actually support biodiversity. Tree-related microhabitats (e.g. cavities, cracks, conks of fungi) are tree-borne features that are reputed to support specific biodiversity for at least a part of species’ life cycles. While several studies have analysed the drivers of microhabitats number and occurrence at the tree scale, they remain limited to a few tree species located in relatively narrow biogeographical ranges. We used a nationwide database of forest reserves where microhabitats were inventoried on more than 22,000 trees. We analysed the effect of tree diameter and living status (alive or dead) on microhabitat number and occurrence per tree, taking into account biogeoclimatic variables and tree genus. We confirmed that larger trees and dead trees bore more microhabitats than their smaller or living counterparts did; we extended these results to a wider range of tree genera and ecological conditions than those studied before. Contrary to our expectations, the total number of microhabitat types per tree barely varied with tree genus–though we did find slightly higher accumulation levels for broadleaves than for conifers–nor did it vary with elevation or soil pH, whatever the living status. We observed the same results for the occurrence of individual microhabitat types. However, accumulation levels with diameter and occurrence on dead trees were higher for microhabitats linked with wood decay processes (e.g. dead branches or woodpecker feeding holes) than for other, epixylic, microhabitats such as epiphytes (ivy, mosses and lichens). Promoting large living and dead trees of several tree species may be a relevant, and nearly universal, way to favour microhabitats and enhance the substrates needed to support specific biodiversity. In the future, a better understanding of microhabitat drivers and dynamics at the tree scale may help to better define their role as biodiversity indicators for large-scale monitoring.
