Different bodies of water support wholly different species communities. Different plant and arthropod fauna can be found depending on the type of runoff, flow level, and human modification. The larger ponds host a combination of introduced and naturally-occurring fish species, along with turtles, frogs, and waterbirds.
Quick-moving streams flow by the school entrance and within the woods.
A slower-moving drainage channel flows around the swampy thicket between Chapel's Field and the library.
Seasonal pools and more established ponds lie deep in the woods.
Chapel's Pond has a unique animal and plant community. It is both highly artificial and species-rich.
Massell Pond is more accessible to waterbirds, and although it presents less favorable growing conditions to aquatic animals and plants, there remains much to be seen.
