Field Notes
Sunny day with light wind (about 75F). Nearby a major roadway with moving traffic and light foot traffic. Lots of wildlife- birds, frogs, turtle, dragonflies, and fish. Some litter in the pond as well. Pond has two docks, but no boat landing. Edge of pond has natural vegetation; however, areas around the buffer zone are mowed.

Supporting Evidence
Photo of my evidence.
This plant did not have thin branches and leaves. There was no square leaf base. Our plant stem was more robust than European Naiad
Photo of my evidence.
The leaves were not jagged and they are spiral in nature. There are not a bunch of branches at the top like the European Naiad exhibits.

This looks like a beautiful spot! It's hard to take photos of aquatic plants, and I think you did a good job.


Great work! I am happy that you didn't find the invasive European naiad.
