Field Notes
We saw greenish-brown water with many ducks. There were fallen trees with larger birds perched on a fallen branch. The trees surrounding the pond have multicolored foliage partially falling in the pond. There are multiple other ponds adjacent to the pond and a graveyard close to it as well. We also noticed that there was a metal pipe inside the pond, although I am not sure the point of it. We were surprised to see this Mysterious pipe in the pond. We were surprised to not see any garbage inside the pond. Finally,we were surprised to see so many leaves

Comments
Mystery pipe
Job well done with your field notes! They are very interesting and descriptive. As I was reading your notes I started to wonder about the pipe you saw in the pond. It seems like a curious place for a pipe since the site was in a graveyard that is probably regularly cleaned and you did not observe any other garbage. I wonder who moved the pipe to the pond and why, the history behind how things came to be where they are is intriguing and very relevant to discussions of invasive species. Do you know of any invasive species that humans have introduced to your area? Do you have any ideas about why people transport invasive species?
