DIVERSITY OF STREET PLANTS IN KATSINA METROPOLIS

Urban street vegetation plays a vital role in enhancing environmental quality, improving urban aesthetics, and supporting biodiversity within rapidly growing cities. This study examines the diversity of street plants in Katsina Metropolis, Nigeria, with the aim of identifying the various plant species, their distribution, and ecological significance within the urban landscape. A systematic field survey was conducted across selected major roads and residential streets within the metropolis. Data were collected through direct observation, species identification, and documentation of plant frequency and abundance. The findings reveal a moderate diversity of street plants dominated by both indigenous and exotic species, including ornamental trees, shrubs, and grasses. Commonly observed species include neem (Azadirachta indica), flamboyant (Delonix regia), and mango (Mangifera indica), which are widely utilized for shade, aesthetic value, and environmental benefits. However, the study also identified challenges such as poor maintenance, unplanned planting, and limited species variation, which may reduce the ecological effectiveness of urban greenery. The study concludes that although street plants contribute significantly to environmental sustainability in Katsina Metropolis, there is a need for improved urban planning and management strategies. It recommends the adoption of structured planting schemes, increased use of native species, and enhanced maintenance practices to promote biodiversity and ensure long-term ecological balance within the city.
