The importance of urban soil condition for tree roots to survive and function in conspicuously hostile built environments has received limited attention. In part, this is because investigating root systems around buildings and hardscapes is fraught with logistical challenges. The goal of this research program is to advance urban tree protection by developing procedures for precisely determining root locations. Such knowledge can inform strategies that lead to greater success in preserving urban trees and the extensive benefits they provide to cities. Urban forests are now widely recognized as an essential contributor to the sustainability of cities and urban quality of life. They provide varied and substantive ecosystem services that include economic, social and environmental benefits (e.g., moderating urban temperature, sequestering atmospheric carbon dioxide, mitigating storm water runoff, and enhancing mental well being). To address limitations that currently limit knowledge of tree root location in urban areas, my research group will advance novel non-invasive methods that take advantage of ground penetrating radar (GPR) to locate urban tree roots, quantify their size, and construct detailed three-dimensional root morphology maps. In this research program, we will develop an automated root detection approach to processing GPR scans for tree root, calibrate and verify its accuracy through physical excavation of roots. Moreover, this research will refine selection and use of GPR hardware, including antenna frequency, and data collection methods for effective and accurate root detection. Ultimately, this research program will contribute to the greening of cities by providing developers, landscape architects and arborists with new tools to more carefully design and redesign the built environment to ensure the resilience of urban trees.********

城市土壤条件对树根生存和在明显敌对的建筑环境中运作的重要性受到了有限的关注。在某种程度上，这是因为研究建筑物和硬景观周围的根系充满后勤挑战。该研究计划的目的是通过开发精确确定根部位置的程序来推动城市树的保护。这些知识可以为策略提供信息，从而导致在维护城市树木及其为城市提供的广泛利益方面取得更大的成功。现在，城市森林被广泛认为是城市可持续性和城市生活质量的重要贡献。它们提供多种多样的实质性生态系统服务，包括经济，社会和环境福利（例如，调节城市温度，隔离大气二氧化碳，减轻雨水径流以及增强精神健康状况）。为了解决当前限制城市地区树根位置知识的局限性，我的研究小组将推进新型的非侵入性方法，这些方法利用地面穿透性雷达（GPR）来定位城市树根，量化其大小并构建详细的三维根部形态图。在该研究计划中，我们将开发一种自动根检测方法来处理树根的GPR扫描，通过物理发掘来校准和验证其准确性。此外，这项研究将完善对GPR硬件的选择和使用，包括天线频率和数据收集方法，以有效，准确的根检测。最终，该研究计划将通过为开发人员，景观建筑师和树木师提供新的工具，以更仔细的设计和重新设计建筑环境，以确保城市树的弹性。********
