This study was carried out to assess the composition and diversity of woody tree species in the parkland of Sudan savannah region of Nigeria. Fifty (50) sampled plots each measuring 25x25m were laid systematically in the Parkland, and woody tree species were determined.  A total of 877 tree species were encountered in the study area, belonging to thirty nine (39) different species, distributed within sixteen (16) families. Fabaceae, Moraceae and combretacea had the highest number of 13, 6 and 4 respectively; followed by Anacardiaceae and Aracaceae with three species each, other families have two or one species each. Shannon’s diversity index (H’) was 3.113, 2.967 and 3.188 for Danbatta, Gezawa and Kibiya respectively. Species Evenness (EH) was 0.8995 (Danbatta), 0.8798 (Gezawa) and 0.8079 (Kibiya), and richness of species stood at 4.276 (Danbatta), 4.205 (Gezawa) and 5.019 (Kibiya). The parkland had high species richness and a moderate diversity on a fairly low fertile soil. Intervention is needed by the governments at all levels, NGOs, and CBOs for proper development, conservation and sustainable use of the tree species on the farms.
