L\u2019\u00e9claircie repr\u00e9sente pour bon nombre de gestionnaires en Europe continentale, l\u2019intervention principale en sylviculture. Les soins aux jeunes peuplements prennent une importance \u00e9galement, parfois au d\u00e9triment de la bonne conduite du renouvellement du peuplement (effets du dosage de la lumi\u00e8re et la bonne structuration des futurs peuplements). L\u2019auteur retrace l\u2019av\u00e8nement historique de l\u2019\u00e9claircie et le r\u00f4le pionnier de la sylviculture suisse en mati\u00e8re de concepts d\u2019\u00e9claircie. Il d\u00e9montre que suite aux chutes dramatiques des rendements forestiers, les concepts de conduite des jeunes peuplements ont d\u00fb \u00eatre reconsid\u00e9r\u00e9s. Il s\u2019av\u00e8re aujourd\u2019hui nettement plus int\u00e9ressant \u00e9conomiquement d\u2019utiliser les processus naturels de diff\u00e9renciation sociale et laisser la nature exprimer les potentiels naturels gratuits. L\u2019application des principes de s\u00e9lection positive aux soins aux jeunes peuplements consiste \u00e0 cibler les interventions en faveur d\u2019un nombre r\u00e9duit d\u2019arbres candidats. Le r\u00f4le important de la structuration des peuplements est analys\u00e9 : pour des questions d\u2019efficience des co\u00fbts, il faut davantage prendre en compte la structuration sociale et mieux l\u2019utiliser comme crit\u00e8re de s\u00e9lection. L\u2019auteur va jusqu\u2019\u00e0 constater qu\u2019il vaut mieux laisser faire le d\u00e9veloppement naturel que le contrecarrer en voulant homog\u00e9n\u00e9iser. Le r\u00e9gime d\u2019\u00e9claircies est d\u2019une importance cruciale dans le cas d\u2019essences sensibles aux temp\u00eates, comme l\u2019\u00e9pic\u00e9a. Le r\u00e9gime d\u2019\u00e9claircies fortes favorise non seulement un meilleur ancrage du syst\u00e8me racinaire, mais favorise le m\u00e9lange d\u2019essences. L\u2019auteur termine en indiquant que le forestier doit se donner les conditions de base propices \u00e0 une gestion polyvalente et l\u2019\u00e9claircie y contribue grandement.
