Biotic and Abiotic Challenges of Urban Trees and Forests

This module includes a seminar segment that imparts theoretical knowledge on tree species in urban and forested environments, focusing on their distinct traits, habitat needs, and the environmental factors affecting them. Students will explore the heightened stress urban trees endure, such as drought from extreme weather due to climate change. The curriculum will address urban trees' unique challenges, like constrained growth space, suboptimal soil quality, and air pollution.

A critical aspect of the module is understanding the risks of mechanical failure in trees caused by pathogens, which is essential for public safety and mitigating incidents like falling branches or trees during storms. Emphasis will be placed on the biology, epidemiology, and infection mechanisms of pests and pathogens, with special attention to both native and invasive fungal species. The module also integrates urban planning discussions and examines future tree species that are more resistant to drought and diseases.

Field trips will provide hands-on experience in identifying disease symptoms and implementing practical pest and pathogen control strategies. The module introduces cutting-edge technologies, including sonic tomography, for tree health assessment.

Students will also engage in independent projects, presenting their findings on urban tree health monitoring to their peers for discussion. Collaborative efforts will culminate in poster presentations, synthesizing key topics, which will be showcased on the module's final day. The program concludes with group studies and a debate on the multifaceted challenges facing urban trees.
