Everglades National Park
This is a nurse log in the middle of one of the hammocks. A nurse log is a fallen log that is rotting. The rotted wood provides stabilization and nutrition for small plants growing on it. If you look closely at the photo you can see that many of the plants are growing from the top and sides of the fallen log. Nurse logs are common in almost all forests. Next time you're hiking in the forest look around and see how many you can spot.
