The study was carried out to investigate plant growth attributes, floristic composition and diversity in Kano Zoological and Botanical Garden, Kano State. 1km systematic line transect was laid with four (4) plots sized 30 by 30m demarcation at 50m interval which makes up a total area of 3600m². All woody plants were identified and classified into families while DBH and height were assessed and used to evaluate volume and Basal area. H¹ index, D and evenness were computed. Floristic composition identified into 9 families, 15 species, 15 genera and 31 individual stands in the Zoological Garden while thirteen species and seven families reported from Biological Garden. The family of Fabaceae had the highest number of frequencies from the two study sites respectively. Other families like Myrtaceae, Arecaceae, Oleacaceae, Euphoboacea, Panaceae occurred once only. The total number of individual tree and species were 31; 28 and 15; 13 for ZG and BG respectively. The mean basal area, mean volume and mean DBH were 92.85m²; 39.89m², 2.09m³ha¹; 0.41m³ha-1, 0.53; 0.34m respectively. H¹, D and evenness were assessed as 4.28;4.22, 0.49; 0.44; and 0.33; 0.28 respectively. Plant species was diverse, less spaced and dense in composition compared to other studies conducted in the savannah landscape. Therefore, indigenous tree, shrub species and agroforestry trees could be introduced into the hotspot for better diversity, recreational, research and educational purposes.
