Maple syrup production (“maple sugaring”) is an important cultural and economic activity in eastern Canada and the northeastern United States (U.S.A.). Climate change is a concern for maple producers because maple sugaring is dependent upon climate for both sap sugar content as well as for the specific patterns of freezing and thawing in springtime needed for sap flow. Meanwhile, the maple industry itself is in transition: historically, maple sugaring has been a small-scale seasonal activity, but today large producers tap thousands of trees, contributing to a widening gap in production volumes and production practices between small- and large-scale producers. Drawing on original survey data from 354 maple producers in Canada and the United States we ask how attitudes towards climate change risks and adaptation strategies differ between smaller-scale and larger-scale producers. Findings suggest that small-scale, medium-scale and large-scale maple producers have different perceptions of climate change risks, report different impacts of climate change on maple sap yields, and have different levels of willingness to use adaptation strategies ranging from tapping more trees to adopting new production technologies. In multivariate ordered logistic regression models controlling for producer age, education, and political affiliation, we consistently find the strongest correlates of attitudes towards climate change risks—and the willingness or ability of producers to adopt different adaptation strategies—are country of residence (with preferred adaptation strategies varying across Canada versus the U.S.A.) and producer scale (with larger producers adopting more adaptation strategies). We conclude that more detailed and up-to-date information on the different types of maple operations—including effects of climate change on maple sugaring and available adaptation strategies across geographies and across scales of production—is needed to help maple producers, maple producer associations, and policymakers understand how the maple industry is evolving and how best to prepare for the future.

枫糖浆生产（“枫糖”）是加拿大东部和美国东北部（美国）的重要文化和经济活动。气候变化是枫树生产者关注的一个问题，因为枫糖的糖化依赖于气候，这既取决于树汁中糖的含量，也取决于树液流动所需的春季冻融的特定模式。同时，枫树业本身正在转型：从历史上看，枫糖业一直是小规模的季节性活动，但如今，大型生产者采摘了数千棵树，导致小规模和大规模之间的产量和生产方式之间的差距不断扩大生产者。根据加拿大和美国354家枫树生产者的原始调查数据，我们询问规模较小的生产者对气候变化风险和适应策略的态度如何不同。研究结果表明，小型，中型和大型枫树生产者对气候变化风险有不同的认识，报告了气候变化对枫树汁产量的不同影响，并且对采用适应策略（从挖更多的树）的意愿不同。采用新的生产技术。在控制生产者年龄，教育程度和政治背景的多元有序逻辑回归模型中，我们始终发现，对气候变化风险的态度与生产者采用不同适应策略的意愿或能力之间的最强关联是居住国（加拿大与美国的偏好适应策略各异）和生产者规模（较大的生产者采用更多的适应策略）。我们的结论是，需要有关枫叶不同类型的更详细和最新的信息，包括气候变化对枫糖的影响以及跨地区和跨生产规模的可用适应策略，以帮助枫叶生产者，枫叶生产者协会，政策制定者了解枫树行业如何发展以及如何为未来做好最好的准备。A.）和生产者规模（较大的生产者采用更多的适应策略）。我们的结论是，需要有关枫叶不同类型的更详细和最新的信息，包括气候变化对枫糖的影响以及跨地区和跨生产规模的可用适应策略，以帮助枫叶生产者，枫叶生产者协会，政策制定者了解枫树行业如何发展以及如何为未来做好最好的准备。A.）和生产者规模（较大的生产者采用更多的适应策略）。我们的结论是，需要有关枫叶不同类型的更详细和最新的信息，包括气候变化对枫糖的影响以及跨地区和跨生产规模的可用适应策略，以帮助枫叶生产者，枫叶生产者协会，政策制定者了解枫树行业如何发展以及如何为未来做好最好的准备。
