Green Heritage and Lanna Urban Identity: A Study of Temples in Chiang Mai Old City

Abstract

This study employs the Historic Urban Landscape (HUL) framework to explore the integration of landscape plants as green heritage with Lanna urban identity in Chiang Mai Old City, Thailand. The research focuses on 38 Lanna temples, investigating the characteristics and roles of plant materials in these sacred spaces. Through comprehensive ground surveys, GIS mapping, and structured interviews with monks, temple caretakers, and long-term residents, the study documents the types, locations, and uses of native and exotic plants. The findings emphasize the cultural, aesthetic, and ecological significance of heritage trees, such as the Bodhi trees and the Yang tree. These trees are pivotal in maintaining cultural continuity, supporting traditional rituals, and enhancing biodiversity. The study also reveals that while ornamental and edible plants are actively used in rituals and community practices, medicinal and applicable plants are preserved more for their historical value than practical use. This research underscores the necessity of sustainable landscape management, community engagement, and the preservation of ethnobotanical knowledge to mitigate the impacts of urbanization. By integrating green heritage into urban planning, the study provides valuable insights for enhancing the cultural and environmental landscape of Chiang Mai.
