The Forest Unseen: A Year's Watch in Nature is a 2012 book written by David G. Haskell.

The book is divided in 43 short chapters ordered by date and roughly covering a whole year.

[1] In each of them the author, which visits almost every day a single square meter randomly chosen of an old-growth forest of Cumberland Plateau (Tennessee), describes what happens to plants, animals and insects living there.

These observations give him the opportunity to write not only about the small-scale forest ecology but also on worldwide natural processes.

He often calls his small observation field mandala,[2] inspired by the paintings of sand created by Tibetan as a support for meditation.
