Background: Roadside trees play an important role in urban landscaping. They are not only related to urban scenes, traffic safety, quality of life, and health, but also closely related to ecology and cultural development. Thus, effective, intelligent management of an area of urban roadside trees will become an important topic. Methods: This paper evaluates survey technologies and management techniques utilized in many cities of Taiwan, including surveys of roadside trees, risk assessment, and precious protected trees. A roadside tree management data- base was built using a geographic information system (GIS). Results: The number of urban forest trees exceeded 100,000 in our surveys, and many types of intelligent survey instruments were used to survey the trees, including real-time kinematic (RTK) and non-destructive detection instruments, radio frequency identification (RFID), in-vehicle light detection and ranging (LiDAR), and panoramic streetscape systems. A tree management system can be constructed by introducing the digitized information, which is based on a basic survey of trees. The survey stage primarily relies on manual surveys, in-vehicle LiDAR, and RFID, and then a visualized database retrieval system will be proposed using GIS. This system can be utilized for the health and foundation management of trees and the whole spatial planning of urban forests, among others. Conclusion: This research attempts to summarize the trends in intelligent management of urban forests using our practical experiences with the goal that it will be a reference for the future intelligent construction of urban forests.

Randrup Sustainable Smart Park Management—A Smarter Approach to Urban Green Space Management? ..............................................................................................................................60 Abstract. In parallel with ongoing discussions on what the concept of a smart city actually entails, use of smart technology in management and governance of urban green space is increasing. Application of smart technologies usually involves multiple sensors, smartphones, internet con- nections, etc., working together to make green space management more inclusive and effective. In the Sustainable Smart Parks project in Gothenburg, Sweden, new technologies are being applied and tested for availability, reliance, and relevance for contemporary management. However, moving these technologies beyond ad-hoc applications and creating a joint systems approach to future management is still unex- plored. In this article, we introduce an analytical framework based on urban ecology and nature-based thinking and use it to examine the Sus- tainable Smart Parks initiative. The framework works well in distinguishing integration of diversity, connectivity, adaptation, inclusion, and perception in different technologies. However, further studies are needed to test adequacy of the 5 initial criteria in a wider context and to increase coupling of smart technologies that share similar focus within each criterion. This would stimulate “systems mapping” and thus clearer progression toward integrated smart green space management. Keywords.

Fischer, PhD Indiana University’s Woodland Campus: A Case Study of Urban Forest Patch Sustainability ....74 Abstract. Background: Urban green spaces are increasingly seen as vital resources contributing to ecological and social health. The ecological concept of patch dynamics over space, scale, and time applies to patches in urban settings and is important in understanding the complexity of relationships between and within the ecological and social spheres interacting in urban settings. Methods: This case study investigates forested and natural patches on Indiana University’s Bloomington (IUB) campus. Data gathered through university archives includes historical maps and campus plans for a study period beginning in 1884 with the university’s relocation to its current area.
