Field Notes
We are happy to be outside and in the sun! I hear birds, yelling, wind and a tree falling. We are at a small muddy pond on the side of the road. A white house is next to it. There are cattails, weeds, grass, fish and ducks in the murky water. The wind is pleasant. Based on available data on surrounding ponds and lakes we predict that there will be no invasive species in Rollo Pond.
Supporting Evidence
Photo of my evidence.
Hydrilla leaves are arranged in whorls. The leaf we found does not have whorls and resembles that of an oak tree. Though found in the water it is flat with points.

Hydrilla have long stems that grow and branch out and form dense mats. We found solid sticks from fallen trees.

Hydrilla form stems that grown up to 3 m long that grow from underground tubers toward the water's surface. We found a root system with a solid center with roots growing out of the sides.
