As more time passes, it gets easier to forget what was there before. And that's just a shame, really. Following is a picture taken pre-illegal earthwork (thank you sender!):

Many, many "pre-destruction" pictures exist.
If one takes these pictures and uses them in conjunction with other available techniques (i.e. using aerial photography to map vegetation/habitat), one will have a better understanding of what was there pre-illegal activity......and what should be there again.....
