The Lorax is a great book to teach others about the importance of the Earth and the natural world around us. At 1:30, Park Interpreter Elizabeth will read this story and then everyone will have the chance to become protectors of the environment, like the Lorax, by taking the Lorax challenge. Pledge to plant Planting a tree is a great way to celebrate Earth Day. Join us in planting a native tree in the park at 3:30pm and what it means to take the "Pledge to Plant".
