Topic: Biodiversity
Wednesday 6/18
I participated in a workshop with other teachers on macroinvertebrates and stream ecology. We hiked just a short distance to a strem. Here, we took the ph level of the stream. ph is a huge deal in the park because of pollution. We, generally, have a higher ph. This can have serious effects on the diversity in the stream. Our ph's were around 5. This, according to previous data in this stream, is slightly lower. We sifted through debris and used to nets to catch insects. We ended up finding a crayfish, a salamander, and a stonefly larvae. The biodiversity of the park never ceases to amaze me. We are so blessed to live in an area that supports so much life. We need to think about everything that is affected by pollution. It doesn't just make a mess, it really creates an unbalance in a balanced world.

Wow. Let me say it again, WOW! I went with the summer research interns to check insect traps. Previously at the canopy trap in Cades Cove, I saw a butterfly that I thought was the Appalachian Brown. We didn't bring any equipment for catching and/ keeping this insect. So, we didn't take a specimen back. However, this time, we brought the stuff and yes it was the Appalachian Brown. This is so exciting. We are the first to identify and record this species in the park! This insect trap is located in an ecotone in Cades Cove. The only trap we found this in was the canopy one. I believe these butterflies may like it high and that is why it has been so difficult to catch int he park. This may be something we discuss in class.
