As far as natural cover the pond has about 5' of reeds/top water grass that extends from the shore along with underwater vegetation. I would say that about 35-45% of the pond has vegetation. Also we have been adding man made structures in the form of PVC trees (4 so far) and about 3 pallet pyramid cribs (not sure what else to call them). Going to add more in a few days before the ice melts and over the summer as well.
