Article published: With increasing site quality asymmetric competition and mortality reduces Scots pine (Pinus sylvestris L.) stand structuring across Europe
An article has just been published in the “Forest Ecology and Management” journal dealing with the stand structuring of monospecific Scots pine forests. This article shows that the stand structuring decreases with site quality because of mortality and asymmetric competition processes. The OPTMix plots contributed to the data of this study based on 90 Scots …
Matias Bentkowski is carrying out his internship at the EFNO unit of INRAE. The aim is to study the impact of summer drought on tree regeneration. The field experiment is done using the OPTMix research facility. It consists of measuring water stress and the annual growth of seedlings of Scots pine and Sessile oak under …
In mixed forests, complementarity can be expressed by a differentiate use of space between species so that each species makes the best use of the light resource according to its photosynthetic capacities. This spatial differentiation between species is possible thanks to plasticity in crown architecture. Thus many articles report an increase in the extent and …

Vallet, T. Perot, L. Arnaudet, A. Calas, C. Proult, D. Devanne and N. Korboulewsky (2021). « Peuplements mélangés à faible densité : une …
Article published: What are the advantages and limits of tree species mixture to face climate changes? The contributions of the OPTMix device
An article presenting the latest results obtained on the OPTMix device was published in the latest issue of the journal “Rendez-Vous Techniques” of the National Forest Office: Korboulewsky, N., P. Balandier, Y. Dumas, M. Gosselin, A. Marell and T. Perot (2021). « Quels intérêts et limites du mélange d’essences face aux changements globaux ? Les apports …
A tree health status scoring campaign was carried out in 2020 on all OPTMix plots on sessile oak and Scots pine tree samples. We used the DEPERIS protocol developed by the French Forest Health Department. A new scoring campaign was carried out in summer 2021. The first analyzes show an increase in the percentage of …
