Trees on the University of Ibadan campus provide significant economic and ecological benefits but also pose potential hazards if poorly managed. This study examines the causes and effects of tree removal across four campus zones: residential areas, administrative areas, parks and gardens, and academic areas. Utilizing structured questionnaires and focus group interviews, we identified species removed and reasons for removal, which included old age, threats to buildings, wind throw, and infrastructural development. Analysis revealed Delonix regia and Albizia glaberima as the most frequently removed species. The primary consequences of tree removal were increased temperatures, storms, and flooding. Effective tree management practices, such as pruning and periodic evaluations, are recommended to mitigate these effects.
