Macroinvertebrates

BMI Sketches

Above are some sketches of different macro invertabrates I found at my site today.

River Sketch

Above is a sketch of the river today at my site. Similarly to yesterday, the water appeared more red-orange. I also noticed how it was much sunnier today.

Misc. Data: Temperature(C): 25.5 Conductivity: 62 pH: 5

BMI Identification

To the right is an image of my bio Macroinvertebrates (BMI) identification sheet. I clearly struggled finding BMIs. I used my net to collect five separate groups of BMIs. In total, I only found fourteen individual BMIs. Each BMI I found was also extremely small; this made it difficult to identify each type of insect. I wonder if my river's lack of sediment between rocks contributed to the lack of BMIs; almost every rock I turned over was smooth and lacking in sedment deposit. I also wonder if the recent storms have caused a greater amount and speed of water in the river, forcing the BMIs to move away from an unstable river.

Day Two Reflection

Today was bright and sunny, even more so than yesterday. i started my data collection by sketching my river. The site had not changed much since yesterday, the water was still a red-ish brown color because of how many rocks were in the water. Next, I sampled the temperature, conductivity, and pH of the water. Finally, I was able to collect some BMIs. I finished up my time at the river with a final sketch of my BMIs before dumping them back into the water. On the way to my car, I saw a GBH! Overall a pretty good day at the river.
