Cruziohyla calcarifer is an uncommon treefrog, sporadically distributed throughout low and mid elevation forest from Honduras through north western Ecuador. It lives in humid forest, and breeds in water filled tree-hollows or stumps. Encounters with this frog in the rainforest are uncommon, and only a few groups exist in captivity, primarily within the confines of zoos and institutions within the US and Europe.
Brian Kubicki has been working with the species at the CRARC reservefor the better part of the decade observing them both in captivity, and doing habitat restoration and augmentation. His work has allowed the wild population ofC. calcariferthroughout his reserve to thrive and grow, to the point that today, artificial breeding sites throughout the reserve teem consistently with tadpoles and adult frogs are now a common sight within the reserve.
