项目摘要
Human-aided movement of species populations in large-scale reforestation programs could be an effective and cost-efficient climate change adaptation strategy. Assisted migration prescriptions in forestry are currently being implemented by several Canadian provincial forestry agencies. Such large-scale management interventions, however, tend to entail the risks of unintended consequences, especially when guided by imperfect models and partial information. This project will fill scientific knowledge gaps and develop robust modeling techniques that can directly inform policy developments for seed transfer at this critical juncture.The central idea of this research program is to use introductions of North American tree species to Europe as a test bed for how these species may grow and survive under novel climatic environments. Especially Sitka spruce and Douglas-fir have been widely tested in Europe for decades, and are commercially planted in many locations where they proved productive and resilient. We use this opportunity to validate our North American habitat models against completely independent data, and by implication evaluate their realism to guide forestry operations under climate change.Specifically, we will test a new class of species distribution model, which was developed to guide choice of planting stock for reforestation in western Canada. We will apply the model trained for Sitka spruce and Douglas-fir to European planting environments, and validate its predictions against data from European provenance trials (20- to 80-year old experimental plantations with known origin of seed sources). Additional validations will be carried out against growth records from tree ring data and up to hundred years of forest inventory records from ten European countries.
在大规模造林计划中,人类辅助的物种种群迁移可能是一种有效且具有成本效益的气候变化适应战略。加拿大几个省级林业机构目前正在执行林业方面的协助移徙规定。然而,这种大规模的管理干预往往会带来意外后果的风险,特别是在不完善的模型和不完整的信息指导下。该项目将填补科学知识的空白,并开发强大的建模技术,在这个关键时刻直接为种子转移政策的制定提供信息。该研究计划的中心思想是将北美树种引入欧洲作为试验台,以了解这些树种如何在新的气候环境下生长和生存。特别是锡特卡云杉和道格拉斯冷杉已经在欧洲进行了数十年的广泛测试,并在许多地方进行了商业种植,证明它们具有生产力和弹性。我们利用这个机会来验证我们的北美栖息地模型对完全独立的数据,并通过暗示评估其现实性,以指导林业业务在气候变化。具体来说,我们将测试一类新的物种分布模型,这是开发来指导选择种植股票在加拿大西部的造林。我们将把为锡特卡云杉和花旗松训练的模型应用于欧洲的种植环境,并根据欧洲种源试验(具有已知种子来源的20至80年历史的实验种植园)的数据验证其预测。将对来自树木年轮数据的生长记录和来自10个欧洲国家长达百年的森林清查记录进行额外的验证。
