Environmental Stakeholders' Perceptions of Urban Native Tree Species Values in Abuja City, Nigeria's Federal Capital Territory

This study was conducted to investigate the value perceptions of native tree species in urban landscape by three groups of environmental stakeholders – residents, estate developers and construction companies that reside in Abuja, the Nigeria’s Federal Capital Territory. A Multi-Criteria Analysis (MCA) of landscape scale ecosystem functions and services valuation scenarios were used. A total of one hundred and eighty (180) sets of questionnaire were distributed equally among the three stakeholders (60 each) to ascertain their perceptions on the need to protect native tree species by asking them to rank eight reasons why the protection of native tree species is important in urban/city landscape. The reasons ranked were (i) Aesthetics and beautification of environment, (ii) Microclimatic and cooling effect, (iii) Windbreak, (iv) Erosion control, (v) Conservation of native tree species, (vi) Obstruction of view to enhance privacy (vii) Economic value of the species and, (viii) Any other reason. Results showed that Aesthetics and beautification of environment ranked first by a combination of all stakeholders, and also by Estate Developers alone, while Erosion control and Economic value of the species were ranked first by the Residents and the Construction Companies, respectively. Stakeholders’ mean scores for Aesthetics & beautification of environment, Microclimatic & cooling effect, Conservation of native tree species, and Obstruction of view to enhance privacy, varied significantly (p < 0.05) while there was no significant differences in their mean scores for Windbreak, Erosion control, and Economic value of the species. The differences in the stakeholders’ perception of the value of native trees as revealed by the rankings and significant differences in scores for some of the value criteria to a large extent underscore the values they place on them which in turn will influence their attitude towards the conservation and protection of the species. Therefore, the need for effective environmental education and enlightenment campaigns to sensitise all stakeholders on the overall values and roles of native trees in the city, is emphasized.
