Field Notes
We are happy because we found the sensitive fern. We see a dirt pile, people, and we are also next to an old shed. We hear a lawn mower, people, and a river. The weather was humid and very hot in the high 80's.

Lovely sketch!

A photo of the fern in its habitat would be helpful (vs of the frond you picked). It grows in lots of places. Do you think it will be 80 again anytime soon?

Did you learn why it is called sensitive fern? Come back to this place after the first frost. This is one of the first plants to die back/turn brown with a slight frost.
