This project seeks to understand the effects of de-icing salt accumulation in soil cells on urban street tree healthand resilience. City trees have considerable functional value as green infrastructure, and are sited as vitalcontributors to urban sustainability. Substantial resources are invested by municipalities, and private industry,across Canada to introduce large-growing trees into urban areas to improve environmental quality, attracteconomic investment, and to enhance quality of life. City streets, however, are exceedingly harsh environmentsfor tree growth. In this NSERC Engage-funded project, Ryerson University will work with industry partner,DeepRoot Canada Corp., a Vancouver-based landscape and stormwater design company, to conduct a robustinvestigation of the impact of de-icing salts, and the associated process of water flushing, post-snow melt, onthe Londonplane (Platanus x acerifolia) trees planted along Queens Quay Boulevard, a prominent Torontostreetscape that was recently revitalized with soil cell technology to improve tree survival and augmentmaintenance practices. We will collect soil, environmental, and biometric data from Queens Quay trees andanalyze them at Ryerson's Urban Forestry Lab with the objectives of (1) measuring de-icing salt concentrationsin soil cells; (2) isolating impacts of salt concentration and soil residence time on tree condition; and, (3)evaluating the maintenance practice of water flushing the soil in the spring to dilute and remove salt residue inthe soil. This project serves as an opportunity for refining urban street tree planting methods and structural soilcell design, which will result in new practices and associated productivity for DeepRoot Canada Corp. and thebroader landscaping industry in Canada.

该项目旨在了解土壤细胞中除冰盐积累对城市街道健康和韧性的影响。城市树具有相当大的功能价值，作为绿色基础设施，并被视为城市可持续性的重要贡献者。加拿大各地的市政当局和私营企业都投资了大量资源，以将大型成长的树木引入城市地区，以改善环境质量，吸引人的经济投资并提高生活质量。然而，城市街道是树木生长的极端恶劣环境。 In this NSERC Engage-funded project, Ryerson University will work with industry partner,DeepRoot Canada Corp., a Vancouver-based landscape and stormwater design company, to conduct a robustinvestigation of the impact of de-icing salts, and the associated process of water flushing, post-snow melt, onthe Londonplane (Platanus x acerifolia) trees planted along Queens Quay Boulevard, a prominent最近对土壤细胞技术振兴的多伦多景观，以改善树木生存和增强维护实践。我们将从皇后区收集土壤，环境和生物识别数据，并在Ryerson的城市林业实验室中以（1）测量冰盐浓度的土壤细胞的目标来收集它们； （2）盐浓度和土壤停留时间对树木状况的隔离影响； （3）评估春季水冲洗水的维护实践，以稀释和去除土壤中的盐残留物。该项目是完善城市街道种植方法和结构土壤纸牌设计的机会，这将导致加拿大Deeproot加拿大迪斯特鲁特（Deeproot Canada Corp.）和加拿大TheBroader园林绿化行业的新实践和相关生产力。
