Trees – they are all around us. They provide us with air to breath and wood that keeps us warm in the winter. We love their presence, their smell, and the sound of their branches in the wind. Despite our close connection with trees, we know relatively little about their daily lives. What do they do all day? What do they do when it gets warmer or colder? How do they respond when we get a lot of rain or it starts to get dry later in the summer? To find out, you can use the below interactive tool to monitor daily changes in tree radius of a Douglas fir tree located near the MOSS field campus in McCall, Idaho.
