Abundance, Distribution and Diversity of Reptiles in Nnamdi Azikiwe University, Anambra State, Nigeria

This study investigates the abundance, distribution, and diversity of reptile species in Nnamdi Azikiwe University, Awka, Nigeria, with a focus on three main habitats: woodland, wetland, and forest. A total of 124 reptiles from 6 families, 9 genera, and 11 species were recorded, with Agama agama being the most abundant. Data collection methods included pitfall and wire mesh traps, active searches, and road surveys. Species richness was highest in the forest habitat (9 species), followed by the woodland (6 species) and wetland (5 species). Reptile diversity was measured using the Shannon-Wiener index, yielding a low value of 1.53, indicating low diversity. The study also highlighted the impact of anthropogenic activities, such as habitat disturbance, on reptile populations. Results showed that the woodland habitat supported the highest reptile abundance, likely due to resource availability. In contrast, the forest habitat exhibited greater species diversity, possibly due to better food and breeding sites. The findings suggest that climatic conditions, seasonality, and human activities significantly influence reptile distribution and abundance. To improve conservation efforts, the study recommends comprehensive surveys, the use of GIS for monitoring, and the implementation of conservation awareness programs to mitigate human impact on reptile populations. The establishment of protected areas within the university is also proposed to safeguard reptile habitats.
