In urban environments, landscape plants play a crucial role. Greenery provides a fresh and vibrant atmosphere, reducing the monotony of rigid concrete structures. Planting trees and greenery in urban areas helps improve the quality of the environment by reducing air pollution, noise, and the urban heat island effect. This, in turn, improves air quality, as well as the physical and mental well-being of urban residents. This study aims to understand the status of pests and diseases affecting landscape plants and propose measures to manage, mitigate, and enhance their resilience in urban environments, with the further application of GIS technologies to develop a data system that will help manage landscape plants quickly and most efficiently. The study utilizes morphological comparison methods to classify plants and identify pests and diseases on landscape plants. In addition, GIS technology is applied for digitizing the collected data using Mapinfo Professional 15 software. The study has collected data on over 500 managed landscape plants along the major roads of Hai Chau District, Da Nang, resulting in the identification of 27 plant species and 12 types of pests and diseases affecting them. In general, the current status of landscape plants in the study area is favorable, pest and disease infestation is minimal. Only a few trees have been found to be leaning or at risk of falling, suggesting their removal and replacement with new trees. Based on the collected data, the authors have created a digitized greenery map of the study area.
