Species Audit
Reptiles and amphibians
Although Calderdale has no nationally important amphibians and reptiles, all those present can be considered Priority Species because they are locally rare, endangered or declining. The main threat to the amphibians is development and loss of habitat. Further survey work is needed to establish the status of common lizard and grass snake.
