Park as a habitat

Here we are at the park close to our school and the task is the same as last time.
Find out what kind of plants and animals live in this habitat?
Nate is trying to catch a spider who is trying to run away. We did let all the living creatures back in their habitat after we observed them a bit. So there should be no spiders, ants, flies, bees brought in to our class.
The tree is a chestnut tree on the photo. Students figured this out since they found a lot of chestnuts under the tree.  Do you recognize the plant on the last photo?
(a burdock)
