|Abstract:||Using planted trees for regeneration can be challenging when the stand replacing disturbance –for example chronic herbivorism- is still effective. In such cases, plantation strategies must integrate management of the top-down pressure by consumers to the bottom-up control related to competition for resources. We explore whether selection of competition-adapted balsam fir (Abies balsamea) seedling stock types (110 cm³, 200 cm³ or 350 cm³) and field preparation could be used together with the management of white-tailed deer (Odocoileus virginianus) populations in order to lower the effect of local competition as well as minimizing browsing on seedlings. Even though it is too early to conclude on the effect of field preparation on the competition for ressources, we conclude that choosing a size-adapted stock can optimize the cost of the restoration scheme following herbivore population reduction.|
