Land cover changes resulting from agricultural expansion and cattle ranching are the primary factors influencing the diversity of amphibian and reptile communities. In this study, we assessed the variation in the diversity of amphibians and reptiles across four land-cover types (ponds, grasslands, temporary crops, and secondary vegetation) in a rural landscape in the Colombian Caribbean region. Amphibians and reptiles were sampled through visual encounter surveys between April and August 2018. A total of 19 species of amphibians (frogs and toads) and 23 species of reptiles (14 lizards, 7 snakes, 1 turtle, and 1 alligator) were recorded. Species diversity differed among land covers, for both amphibians and reptiles. Amphibian diversity was higher in ponds and lower in grasslands, whereas reptile diversity was higher in secondary vegetation and lower in temporary crops. Our results suggest that the maintenance of ponds and secondary vegetation could be important for the conservation of herpetofauna in rural landscapes where anthropogenic activities such as agriculture and cattle ranching predominate.
