The study assesses the functional status of the University of Energy and Natural Resources’ (UENR) bat sanctuary by examining its floral diversity and carbon stocks. Twenty-nine sampling points (plots) were randomly generated by using the ArcGIS random sampling algorithm. Using a three-nest sampling plot of 100m2, 25m2, and 1m2 quadrat, the enumeration of trees (DBH>10cm), saplings (>2cm DBH <10cm) and seedlings (girth <2cm) was undertaken, respectively. Additionally, the diversity of each floral species was computed using the Shannon Wiener diversity index whilst the carbon stocks were estimated using allometric equations. The total carbon stock per plot was derived from the summation of the aboveground carbon (AGC), belowground carbon (BGC) and deadwood carbon (DWC). In sum, 450 floral individuals belonging to 47 species and 22 families were enumerated with Bignoniaceae (16.4%), Apocynaceae (10.0%), Caesalpiniaceae (9.2%) and Rubiaceae (8.8%) being the most common families within the protected area (PA). The average carbon sequestered per hectare of the PA was 2,789.3 tons. However, there was no significant difference (p>0.05) between the 10m buffer created and the core area with respect to species diversity and carbon stocks. The study has provided valuable information on the functional status of the bat sanctuary which will help promote its conservation for sustained provision of ecosystem services.
