I just returned from a trip to India where we visited Thekkady (which literally means under the teak tree) and were able to hike through a teak and sandalwood forest in the Periyar Tiger Preserve. While we didn't see any tigers, it was fascinating to see how they are maintaining the forest to allow the over-logged trees to regrow. The first two attached images show one of each tree. They number and register tree and then maintain a 24 hour watch over each section of the forest to prevent poaching. If you look carefully, the third picture shows the shelter with a man keeping watch. The structure in the tree is a safety shelter in case elephants come into the area.
