Using urban street trees as its central subject, the project is built around the core idea: “Don’t let the trees on this island become fallen trees.” Against the backdrop of increasingly frequent extreme climate events and high-density urban development, street tree failures have emerged as a growing public safety concern, revealing the alienation and imbalance in the relationship between people and nature within Taiwanese cities. Starting from this phenomenon, the project focuses on the living conditions of urban street trees and the long-overlooked risks they face. Through an integrated design approach spanning visual communication, product design, and spatial intervention, it further introduces the concept of risk education—emphasizing the importance of cultivating awareness from everyday life and early stages of growth. By strengthening public sensitivity and judgment toward environmental safety, the project ultimately aims to enhance overall urban resilience.
