Basically, they are transforming the southern pond into an "urban ecosystem", returning native species of fish, plants, birds, frogs, and the like back to the area. I vaguely remember seeing something about the project on the news earlier in the spring; they had to kill off a number of the non-native plants and critters that were inhabiting the pond before the renovation, which made me sad, but I'm all for restored wetlands and furthering the native species and the like.
I'm not quite sure how I imagined they would go about "restoring the natural habitat", but I certainly was not expecting to see this:
Cranes and bulldozers and idle construction workers, oh my! I guess I never figured they'd have to do a complete demolition to make a natural restoration; I expected them to just make improvements to the existing pond. Not so. I'm looking forward to seeing the finished product, which the sign assures me will be "an outdoor classroom for students of all ages", I just find their restoration methods a bit ironic.
