Wikipedia shows some images of Iwo Jima as it looks nowadays, at least it gives an indication of the vegetation 'cause those photo's were made in February and March, the same period of the year as the battle took place.
Looking at the weather data it must have vegetation the entire year.

To me it all looks more greenish, yellow and sandy then expected. The beaches do have the dark brown colour though.

Maybe this link will help; the scale model which was used by the US during the invasion shows where the vegetation was and the dark coloured beaches.
