Ecosystem-based FORest management in a Changing Environment (EFORCE)

森林生态系统为加拿大人提供了许多社会经济利益。然而，这些森林及其提供的服务受到了应对气候变化和森林管理的不确定轨迹的威胁。魁北克森林、野生动物和公园部(MFWP)是我们的主要合作伙伴组织，负责魁北克76万平方公里森林总面积中92%的可持续管理。通过依靠基于生态系统的森林管理(EBFM)战略，MFWP寻求保持森林生态系统的抵抗力和复原力。在这种情况下，森林和野生动植物资源研究部门必须产生、整合和转让有关森林和野生动物资源的新知识，以帮助决策者改进管理和养护实践。然而，MFWP的研究分支经常与学术界建立合作关系，以实现他们的所有目标。该项目是与MFWP研究人员共同开发的，目的是找到满足普遍需求的创新答案，减少不确定性，并支持决策。我们的研究问题分为四个主题。第一个重点是评估气候变化对树种生态进化动态和森林生产力的影响。第二个主题涉及野生动物管理，因为一些物种，如驼鹿，从密集采伐木材造成的新环境条件中受益，而其他物种，如驯鹿，则有所下降。第三个主题是人工林培育和管理，通过开发创新的间伐方法和评估幼龄人工林对云杉潜伏虫暴发的脆弱性。最后一个主题旨在开发支持森林管理决策的建模工具。通过MFWP研究人员和实践者的直接参与，确保了向决策者的有效转移。

Forest ecosystems provide many socioeconomic benefits to Canadians. However, these forests and the services they hold are threatened by uncertain trajectories in response to climate change and forest management.Québec's Ministry of Forests, Wildlife and Parks (MFWP), our main partner organization, is responsible bylaw for the sustainable management of 92% of the 760 000 km2 of total forested area of Québec. By relying on ecosystem-based forest management (EBFM) strategies, MFWP seeks to maintain forest ecosystems' resistance and resilience. In this context, the MFWP research branch has to produce, integrate and transfer newknowledge on forest and wildlife resources in order to help decision makers improve management andconservation practises. However, MFWP's research branch routinely establishes collaborations with academia to achieve all their objectives. This project was co-developed with MFWP researchers in order to find innovative answers to prevailing needs, reduce uncertainty and support decision making. Our researchquestions are divided into 4 themes. The first one concentrates on assessing impact of climate change on eco-evolutionary dynamics of tree species and forest productivity. The second theme addresses wildlife management, as some species such as moose have benefited from the new environmental conditions that have resulted from intense timber harvesting while others like caribou have declined. The third theme is oriented towards plantation silviculture and management, by developing innovative thinning methods and assessing the vulnerability of young plantations to spruce budworm outbreak. The last theme aims to develop modelling tools to support forest management decisions. Efficient transfer to decision makers is ensured through direct involvement of MFWP researchers and practitioners.
