We wanted to test a simple, low-cost way to slow this process and help restore open grassy areas. In our study, we created small clearings (“glades”) by cutting trees in a heavily wooded savanna in South Africa. We compared these … Continue reading Creating small clearings helps herbivores keep trees from taking over savannas
