Urban forests (UF) are associated with important ecosystem services, such as reduced heat and improved air quality, which benefit both environmental and human health. These benefits will become even more important with climate change (CC), yet it is unclear how the UF will be impacted by CC, how that will affect human health, and how the UF can be adapted to face CC and better support ecosystem services. This includes removing carbon, which Canada has an obligation to report on. Current estimates of the UF carbon in Canada use rates based on empirical observations made in United States and/or in natural forests. This has been identified as an important source of uncertainty that needs to be addressed to forecast future UF density and composition, and to investigate the hypothesis that the effects of CC on people may be greater than previously thought if trees are also themselves affected negatively. Features such as tree size and crown shape that influence resilience to CC and ecosystem services in UF are also different than in natural forests. Yet incomplete inventories of urban trees and a paucity of data on canopies means that relevant data for modeling and prediction of service production is scarce. Our goal is to better characterize UF with richer data, and to identify best practices for developing resilient UFs that will support ecosystem services now and in the future.

城市森林(UF)与重要的生态系统服务有关，例如减少热量和改善空气 质量，这对环境和人类健康都有利。这些好处将变得更加重要 随着气候变化(CC)的到来，目前尚不清楚气候变化将如何影响UF，这将如何影响人类 健康，以及如何调整UF以面对CC并更好地支持生态系统服务。这包括 消除碳排放，加拿大有义务报告这一点。加拿大目前对UF碳的估计 使用率基于在美国和/或在天然林中进行的经验观察。这已经是 被确定为需要解决的重要不确定性来源，以预测未来的超滤密度和 成分，并调查CC对人的影响可能比以前更大的假设 如果树木本身也受到负面影响的话。树的大小和树冠形状等特征 UF对CC和生态系统服务的影响弹性也不同于天然林。还没有 城市树木的不完整清单和关于树冠的数据匮乏意味着用于建模的相关数据 而且对服务生产的预测也很匮乏。我们的目标是用更丰富的数据更好地描述用友，并 确定用于开发具有弹性的UF的最佳实践，这些UF将支持现在和未来的生态系统服务。
