Calling all students, teachers and citizens of Alberta! Did you know that earthworms are not native to most of Canada and are invading our forests? Join the University of Alberta in collecting data about earthworms across the province. The data that you collect with this app will be used by researchers to study the earthworm invasion in our province. Visit our web site (http://worms.educ.ualberta.ca) for more information about earthworms, lesson plans for teachers, earthworm data and more!
