At the time of this study a portion of the University forest was cut down and burnt. The three study sites investigated were: Distance Learning Institute (DLI), High Rise Area and Lagoon Front Area. Data collected from the study sites were subjected to diversity indices, descriptive statistics and diversity t-Test. A total of 787 individuals of Dragonflies and Damselflies from 13 genera, 3 families and 21 species were sampled. The three families include Coenagrionidae (62%), Libellulidae (36%) and Platycnemididae (2%). The most dominant species was Ceriagrion glabrum (42%) followed by Acisoma panoipoides (10%). The DLI study site had the richest odonate fauna (Shannon Wiener index (H' = 1.94), Simpson’s Dominance index (C = 0.85); while the least was the High Rise study site (Shannon Wiener index (H' = 1.91), Simpson’s Dominance index (C = 0.85). The distribution of the fauna was highest at DLI study site (Evenness = 0.99), followed by Lagoon front (0.98) and High rise (0.97).
