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.〔(Summit Area Trails )〕 == History == Hawaii's first territorial forester, Ralph Hosmer, imported tree species from around the world in hopes of creating a viable timber industry. In 1927 he began planting stands of pine, spruce, cedar and eucalyptus at this site, which can still be seen today in the grove. Only 20 of the 86 species introduced survived: those with shallow roots were blown down in storms, others found the soil chemistry or fungi unsuitable for growth or reproduction. A few thrived, escaping from Hosmer's experimental forest. The Mexican weeping pine (''Pinus patula''), Monterey pine (''Pinus radiata''), and eucalyptus have become aggressive invaders and are now recognized threats to the native ecosystems within Haleakala National Park.
