** Dear Colleagues, We have organized the session on “Advances towards more accurate forest biodiversity indicators and monitoring” (T3.1) during the last June IUFRO 2024 congress in Stockholm. As an add-on to this session, we have succeeded organizing a special issue in Forest Ecology and Management (FEM) that would gather presentations coming from this session – as well as other papers on the same topic (cf. https://www.sciencedirect.com/special-issue/313868/forest-biodiversity-indi… ). You are therefore welcome to propose manuscripts for publication in this special issue, given they fit well with the scope of the SI. Submissions should be done before end of January 2025. Submitted manuscripts will of course go through the classical reviewing process of FEM. If you have any question, do not hesitate to ask. We thank you very much for your attention as well as to the authors who will contribute to this special issue. All the best, Frédéric Gosselin, Anna Barbati, Francesco Chianucci, Marion Gosselin, Sabina Burrascano PS: apologies for cross posting! *Frédéric GOSSELIN* frederic.gosselin(a)inrae.fr <mailto:frederic.gosselin@inrae.fr> *Ingénieur (IGPEF, HDR) en écologie forestière & biométrie* *UR EFNO - INRAE* Domaine des Barres F-45290 Nogent-sur-Vernisson Tél. : +33 2 38 95 03 58 *www.inrae.fr <http://www.inrae.fr/>* bloc-logo-signature-inrae
