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 we have discontinued our app and online form, 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. To learn more about the transition, read our blog.

Thank you to our atlas users who have contributed so many valuable sightings, we owe the success of this program to you!
