Field Notes
Our group, the Invasive Crab Association went to Reid State Park for our field work. It was a rocky area with a few sandy parts and was covered with very slippery seaweed. The weather was very sunny with a little breeze, the temperature was 62 degrees. We used a 1 meter by 1 meter pvc pipe quadrant to cover an area of land to search for crabs. We usually placed our quadrant on or near rocks covered in seaweed with a bit of water in the area. We did this because our belief was that the crabs liked that area.
