Une \u00e9tude men\u00e9e \u00e0 l\u2019\u00e9chelle de la Wallonie a permis de mettre en \u00e9vidence les param\u00e8tres dendrom\u00e9triques favorables au d\u00e9veloppement des semis de douglas. Elle est bas\u00e9e sur les donn\u00e9es de l\u2019Inventaire Permanent des Ressources Foresti\u00e8res de Wallonie auxquelles ont \u00e9t\u00e9 coupl\u00e9es des observations sp\u00e9cifiques \u00e0 la r\u00e9g\u00e9n\u00e9ration. Les r\u00e9sultats montrent que plus les peuplements sont \u00e2g\u00e9s, plus l\u2019apparition et le d\u00e9veloppement des semis sont favoris\u00e9s. La proportion de douglasaies en r\u00e9g\u00e9n\u00e9ration atteint m\u00eame 50 % dans les peuplements dont l\u2019\u00e2ge d\u00e9passe 80 ans. La croissance de la r\u00e9g\u00e9n\u00e9ration est \u00e9galement encourag\u00e9e dans les peuplements peu denses. L\u2019effet de la surface terri\u00e8re et du nombre de tiges par hectare est marqu\u00e9. Le d\u00e9veloppement des semis reste tout de m\u00eame encourageant sous des peuplements peu \u00e9claircis. Si la tendance actuelle des gestionnaires \u00e0 privil\u00e9gier des dimensions d\u2019exploitabilit\u00e9 plus \u00e9lev\u00e9es se maintient, la proportion de douglasaies en r\u00e9g\u00e9n\u00e9ration ne devrait faire qu\u2019augmenter dans les prochaines d\u00e9cennies. Le d\u00e9veloppement ais\u00e9 des semis au sein de peuplements plus ou moins denses permet d\u2019affirmer que la r\u00e9g\u00e9n\u00e9ration naturelle du douglas est une opportunit\u00e9 pour les gestionnaires de renouveler leurs peuplements \u00e0 moindre frais.
