Day 2 in the field- Performing our first run of water chemistry tests yielded some reassuring initial data. Two of our sample sites tested over 90% saturated for dissolved oxygen, which is good news for the small fish, frogs, and salamanders we found in the stream yesterday and put back after getting a few good looks to admire them for a moment. It’s also good news for the macroinvertebrates that we didn’t find. I’m sure they are quite content to still be nestled in the streambed on the underside of a rock instead of being transported out of Tryon-Weber Woods in a bucket! The rest are back at the lab, preserved in ethanol, waiting for us to correctly classify them. We’ve had several pollution sensitive organisms like mayfly and stonefly nymphs and caddisfly larvae. After yesterday and today I don’t think our group will forget what a crane fly larvae looks like or how active it became when we removed it from the stream!
