Abstract: This study investigated the availability, distribution, characteristics and quality of urban ecological infrastructures (UEIs) within the FCT, Abuja. Data collected include coordinates, population figures, and sizes of various UEIs alongside a quadrat sampling technique for robust data collection. The study also utilized, frequency counts, percentages and assessed the quality of UEI’s based on plant biodiversity and accessibility. The identified UEI included Cemeteries, Wetlands, Street Trees, Shelter Belts, Riparian Vegetation, Rivers/Lakes, Rocks/Mountains, and Recreational Parks. The study reveals that recreational parks dominate the FCC's urban landscape, accounting for 26.83% of identified UEIs, followed by street trees at 19.51%. Shelter belts, riparian vegetation, wetlands, cemetery, water bodies, and rocks/mountains contribute 14.63%, 12.2%, 9.76%, 7.32%, and 4.88%, respectively. Results indicated that rivers/lakes exhibited the highest per capita ecological value at 16.14 m² per person, followed by recreational parks and rocks/mountains at 2.55 m² and 1.33 m² per person, respectively. Conversely, urban ecological assets like cemeteries, wetlands, shelter belts, riparian vegetation, and street trees showed per capita values below one. An assessment of location-specific quality indicates that cemetery, riparian vegetation, rocks/mountains, parks, street trees, and wetlands exhibit a mean rating of 2.5, suggesting fair plant biodiversity and moderate accessibility. Conversely, shelter belts and water bodies scored a mean rating of 2, indicating moderate plant biodiversity and somewhat accessibility. The study's findings highlight the need for urgent conservation efforts, considering the ecological implications of UEI degradation.
