We reviewed the results from our Stream Survey of Invertebrates. We determined that the stream is actually pretty healthy based on the types of species that we found present. We talked about how the food web of the stream is very connected to the ecosystem through which it flows. A lot of food gets washed into the stream when it rains and especially when the trees lose their leaves.
