Résumé
Background: This study assessed the diversity and distribution of ornamental plants within the University of Delta Main Campus, Agbor, Nigeria. This would provide a foundational checklist of the vegetation, life forms, and spatial distribution within the study area.
Methods A descriptive survey design involving direct field observation was employed to identify and document ornamental plant species across 17 locations within the campus. Plant identification was conducted using standard taxonomic guides and digital plant identification tools.
Results: A total of 17 ornamental plant species belonging to 14 botanical families were recorded. The dominant families were Euphorbiaceae and Arecaceae. Juniperus chinensis was the most abundant species, while Dypsis lutescens was the least represented. Diversity indices showed considerable variation among sites, with the Sports Unit exhibiting the highest Shannon diversity index (H? = 1.427) and Fisher's alpha (4.632), indicating relatively high species richness and evenness. Conversely, the 1000-Capacity Hall, Faculty of Performing Arts, and Management Block exhibited the lowest diversity values.
Conclusion: The findings highlight the importance of ornamental plants in enhancing campus aesthetics, biodiversity conservation, and environmental sustainability. The study recommends increased planting of diverse native ornamental species and regular landscape assessment to improve ecological resilience within the university environment.
