Reptiles and Amphibians

Ontario is a vast province, rich in biodiversity. Yet every year, more plants and animals are added to Ontario’s list of species at risk, which now numbers more than 200. In response, Ontario Nature is actively involved in research, public education and policy work on their behalf.

Please Read: Big Changes to the Ontario Reptile and Amphibian Atlas

The Atlas is transitioning into a new era, with Ontario Nature wrapping-up the data collection phase of this project as of December 1, 2019. Now that our app and online form have gone offline, we encourage you to continue submitting any future observations through the ‘Herps of Ontario’ project on iNaturalist or directly to the Natural Heritage Information Centre for species at risk. Please note that the interactive maps have been taken offline and will be replaced with static maps. To learn more about the transition, read our blog.
