U of G Naturalist Highlights Ontario’s Must-See Outdoor Areas in New Guidebook

Guelph naturalist Chris Earley faced a key challenge when he set out to co-author a new guidebook to must-see natural areas in Ontario.

Arboretum Biologist's Weird Frog book in Ontario's Forest of Reading Program

Chris Earley's latest children's book, Weird Frogs, has been chosen as one of the titles in an Ontario-wide reading contest.

Annually, our docent (teaching volunteers) group does what is called "Docent Day." This is a full day docent training session that adds to our regular 2-hour monthly sessions. On Docent Day, each docent picks a topic and teaches the rest of us about it. Recently, Joy Killen chose the topic of "vision" and read us this lovely article that she wrote. We thought we would share it with you.
