My neighbors sometimes wondered why I don't trim it up and make it look "nice" right up to the water like some folks do.
I like it wild, lots of trees and wildlife. I even let the wildness take a bit more of the yard than when i moved in. A few big trees quickly sprung up, no maintenance (compared to a yard) it looks great wild.
Perhaps if only out of laziness (yard work is kinda a pain). A few other neighbors who were maliciously caring for their lawn right up to the marsh (well the area you can do that to legally) have done the same as I have and we've got a much larger wild area now. It's full of blue jays, finches, cardinals, rabbits, owl visitors. We even get visited by some beautiful red foxes from time to time (i suspect quite often but they are very sneaky).
The kids mostly play in the front yard anyway where I actually bother to do more yard work to make it looks nice so a big lawn in the back makes no sense if nobody is really enjoying it.
