Young volunteers with the Friends of Fish Creek Provincial Park Society in Calgary are monitoring the park’s garter snake population, the Calgary Herald reports. “‘Each spring the park sets up 10 wooden traps that catch the snakes as they move from the hibernaculum to the creek,’ says the children’s mother, Jennifer Brown. Teams of volunteers visit the traps twice a day, seven days a week, in all types of weather. The monitoring takes place from April to June, though the exact timing depends on the spring thaw.”
