That tree look like very old and down from above part but flowers and small plants around tree are looking good. Heat always destroy thing weather its living or non living thing. That tree look little different then others tree and there is something comes out from inside it look like.
The tree is dying by lack of natural water. It's roots once fed from the nearby river, but now it can't. Oh and yes, the tree is VERY OLD from the time there were tribes and no Spanish conquerors on the island yet.
