The Governance of Amenity Trees in the Premises of Industrial Companies in Ibadan Metropolis, Nigeria

Industries contribute to environmental pollution, and increasing tree cover is an often-proposed urban climate change adaptation strategy. This manuscript investigates the governance of amenity trees within industrial settings in Ibadan, Nigeria. It aims to encourage industries to develop policy frameworks that optimize tree management for environmental benefits. This study involved surveying twenty purposively selected active industries and analyzing the data through descriptive, correlation, and chi-square methods to assess tree species diversity, management practices, and the relationships between the number of species and the land area, as well as tree establishment and silvicultural activities. Polyalthia longifolia (30.8%) had the highest number, while Eucalyptus camaldulensis and Alstonia boonei (0.6%) had the lowest numbers. The respondents (38.3%) revealed that there was no department (unit) responsible for tree management, and there was no precise tree maintenance schedule. However, tree maintenance is conducted when needed. The respondents (98.0%) responded that no funds were set aside for tree management. The result of the correlation, r = −0.14412, represents a weak negative relationship between the number of tree species planted and the land area of the industries. The year in which trees were planted has a significant relationship with the silvicultural activities practiced.
