Studying the response of anurans to anthropogenic disturbance can be very useful in determining the potentiality of this species as bio-indicator. The study was conducted to assess and describe the habitat condition (i.e., microclimatic, microhabitat, and vegetation structures) and species richness of anurans as affected by the degree of disturbance due to anthropogenic activities in Silago, Southern Leyte, Philippines. Four (10 x 10m) quadrats were established in each site using opportunistic approach in the collection of anurans within the plots per site. Likewise, measurement on the factors associated with habitat condition such as microclimate, habitat, and vegetation structure were undertaken. The collection was done both in daytime and nighttime. The results showed that microclimate, habitat, and vegetation structure differed significantly (p≤0.01) in each site. This implies that the three sites had different degrees of disturbance that altered the habitat condition of anurans. Moreover, anuran species richness significantly differed (p≤0.05) in primary forest and slash and burn cultivation but there was no significant difference between secondary and primary forest. Therefore, the results of this study may indicate that the degree of anthropogenic disturbance considerably (p≤0.01) alters anuran’s habitat conditions which significantly (p≤0.05) affect its species richness.
