Are you trying to make the island more green with more vegetation?
Wouldn't most of the vegetation have been blown up by the bombardment and shelling?
I would also think that all trees would have been cut down by the Japanese to use for their hundreds of bunkers and fortifications.

As far as I know Iwo Jima has never had a tree.http://www.youtube.com/watch?v=rjVukqPXJHg copy and paste link into your web browser very good views of Iwo Jima.
