In my personal opinion, the City Nature Challenge was a whole lot of fun! iNaturalist is a neat little app, and outside of NR2 I still use it on my day to day travels.
The place I explored the most for the City Nature Challenge was on a little island in Winooski, mostly made up of birch, spruce, and cedar. What I found especially cool about the place we explored, there was cedar growing right out of the abandoned buildings/structures all around us! It was like a cedar bonanza!

This probably means that the surrounding environment is pretty acidic and moist, as that is where red cedar thrive the most.

And here was some little paper birch leaves peeking out to say hi, ready to grow into big strong leaves for the summer!
Other species of wildlife we saw were a pair of common merganser, and a lone Canada goose. Unfortunately I was unable to document the birds, because the goose was quite aggressive about protecting its nest.
I found it extremely breathtaking to see the biodiversity across the globe through the world wide city nature challenge. But I was also super surprised about how many species we see right here in Burlington are super common all across the world! I hope to think people from Tokyo were just as interested to see the species that was spotted in Vermont as I was seeing their species.
