We have an idea of what makes people healthy: They eat right, they work out, and they don’t get sick very often. But what makes land healthy? To give you an idea, I went to the Allegan State Game Area. It has two pieces of land that — when it comes to health — couldn’t be more different. The first one is a thriving oak savanna.
