Hosmer's Grove is an example of experimental forestation from Hawaii's territorial days. Located just inside Haleakala National Park near the summit of Haleakala in Maui, Hawaii, it includes a campsite and several hiking trails. The grove is well known amongst birdwatchers due to the abundance of endemic honeycreepers at the site, including Iiwi, Apapane, Hawaii Amakihi, and the Maui Alauahio.
