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.

I know...A question for all the people here. Does you have any idea of what was the look of Iwo before U.S start bombing it? Was there a that period of the year only sand of still vegetaltion?
