High beech regeneration density is a concern in northern shade tolerant hardwood forests. densities of ( Fagus grandifolia Ehrh) can crowd out other desirable species, such as sugar maple Acer saccharum Marsh.), and jeopardize long-term sustainability since under threat from bark disease Cryptococcus fagisuga/Neonectria spp. Complex). We examined the efficacy three tending (no tending, brush saw, basal herbicide) two timing harvesting (deferred 5 years post-single tree selection harvest, concurrent with uniform shelterwood harvest) treatments on reducing promoting over 6 years. Six after we found that large was reduced, medium had recovered to pre-tending levels most treatments, small remained unaffected. Tending no effect any size class but harvest promoted more than single-tree harvest. Despite this increase, all treatment combinations below stocking targets. Our results suggest while temporarily reduce densities, unable take advantage increased growing space.

Le site du ravin de Parkside a été mis en place 1967, suivi par l’addition d’une parcelle non exploitée 1974 afin répondre aux questions portant sur le jardinage pied d’arbre Ontario. exploité une dernière fois à grande échelle au début des années 1930. Depuis connu quatre récoltes expérimentales. Les méthodologies mesurage ont changé et n’ont pas reproduites. Cependant, demeure l’une expériences les plus longues d’arbres Canada comporte précieuses informations. Au cours la présente étude, nous avons utilisé données provenance 15 parcelles d’un acre (10 exploitées, 5 témoins) pour démontrer période 56 ans, que maintenu densité, structure objectifs d’amélioration qualité tout long écoulées. même période, densité dans témoins diminué, tandis s’est améliorée, cependant un rythme lent. Nous constaté également tiges haute valeur présentent risque mortalité faible croissent vite valeur. Malgré fait tous reliés peuplement atteints, démontré développement hêtre problématique: supplante l’érable est dominant niveau régénération depuis moins 2005, malgré l’absence maladie corticale hêtre. La compréhension ce qui permet récolte Ontario essentiel maintien durabilité mode prochaines années.
