Forest and their resources are essential to the long-term well-being of Canadians, their environment and their economy. Sustainable development practices are thus critical in the forest industry. Understanding the dynamics of forest regeneration is a key element that needs to be taken into account by logging companies to predict their timber supplies. Browsing by large herbivores (e.g. deer and moose) is one of the factors whose impacts on forest regeneration need to be quantified and managed. AV Group Inc., a pulp company conducting logging activities, wants to estimate the financial losses associated with browsing activities of hardwood regeneration by large herbivores. The first step to estimate such losses is to quantify experimentally the impacts of large herbivores on hardwood regeneration following harvesting. The objective of the project is to set up an experimental design to quantify the impact of large herbivores on natural forest regeneration in managed hardwood stands following harvesting. A total of n=15 plots will be selected in 5 cuts (3 plots per cuts) that will be harvested in 2019 in one of the forest lands managed by AV group (Western NB: Northwest of Fredericton in York County). The K.-C.-Irving Research Chair's team will sample the regeneration and the composition of the field layer in late July 2019 prior to the harvesting operations, and will repeat this sampling every two years (this later step conducted using other funding sources). Close collaboration between the K.-C.-Irving Research Chair and AV Group will ensure timely completion of the proposed project. This project is one of the steps required to determine whether management of large herbivore at densities that are compatible with regeneration of species is needed in both exploited and natural forests.

森林及其资源对加拿大人的长期福祉、环境和经济至关重要。因此，可持续发展做法对森林业至关重要。了解森林更新的动态是伐木公司在预测其木材供应时需要考虑的一个关键因素。大型食草动物(如鹿和驼鹿)的觅食是其对森林更新的影响需要量化和管理的因素之一。从事伐木活动的纸浆公司AV Group Inc.希望估计与大型食草动物浏览硬木更新活动相关的经济损失。估计这种损失的第一步是从实验上量化大型食草动物对收获后硬木再生的影响。该项目的目标是建立一个实验设计，以量化大型食草动物对受管理的阔叶林采伐后天然森林更新的影响。共有n=15个地块将在5次采伐中选出(每次采伐3块)，2019年将在AV集团管理的一片林地(西北亚：约克县弗雷德里克顿西北部)收获。欧文研究主席的团队将于2019年7月下旬在收获作业之前对农田层的再生和组成进行采样，并将每两年重复一次采样(这一后续步骤使用其他资金来源进行)。K-C-欧文研究主席和反病毒小组之间的密切合作将确保及时完成拟议的项目。该项目是确定是否需要在已开发森林和天然森林中以与物种再生相适应的密度管理大型食草动物所需的步骤之一。
