In the picture above you can see the sediment that used to be the stream bottom. Beavers dammed the flow up stream and slowed the outfall thus making a wide and somewhat channelized river much smaller and much more complex. Now this creek meanders gently through the woods in and around Robinwood Park. The structure of the pond at this site is amazing! Some emergent water plants, skunk cabbage, grasses on the pond edge as well as larger bladed plants as well – “macrophytes”. It looks like a wonderfully diverse ecosystem.
