pisonia (pisonia grandis)
One thing I find amazing about this tree is that when it dies it gets born again! Isn't that cool. It is the main tree that Black Noddys nest in. 75% of the Pisonias population is on Heron Island! Some times the seeds of the Pisonia tree will get stuck in a Noddys feathers, when this happens it can no longer fly and will die. The dead Black Noddy gives nutrition to the tree. This may seem harsh, but this is natures way.
threats
A worm will eat into the Pisonia tree and when the tree gets stressed it will suck up more nutrients and when it gets too stressed it will die!
conservation
Heron Island introduced with permission a wasp that kills the worm that threatens the Pisonia tree.
