I like the idea to keep some of it. It's a natural phenomena that you should have. But, if it covers most of the pond, I can see the need to remove a portion of it. As a matter of fact, that's what Bruce Kania biomimics when he uses his floating islands.
A floating bog and the plants on it absorbs and use nutrients from the water. They play a role cleansing water.
Yes, the county wetland people, where baffled by this 3/4 acre pond and it's "bog". They say it is very rare/unusual for this area and would hate for me to remove it, just because it is so interesting. But, from old sat and air photos, you can see it has grown a great deal over the years, and now covers most of the pond.
The reason for the 1/2 to 3/4 acres is it varies about that much depending on water level.
