For more than a century, this grove of experimental silviculture of eucalyptus, pines, and other conifers has sat at the edge of a native wet montane forest and open native shrubland on the slopes of the Haleakala Volcano, at nearly 7,000 feet above sea level. The grove is my go-to place on Maui to view endemic Hawaiian honeycreepers. At any time of year, you might see Maui ‘Alauahio, ‘Apapane, ‘I’iwi, and Hawai’i ‘Amakihi as well as the state bird, the Hawaiian Goose (Nene) and the native subspecies of Short-eared Owl (Pueo) in the parking area, campground, and along the short loop trail that winds through the grove and open native shrub vegetation. Approximately 40 bird species have been recorded here. Non-natives you may encounter include Ring-necked Pheasant, Japanese Bush-Warbler, Japanese White-Eye, Chinese Hwamei, and Red-billed Leiothrix.
My favorite section along the loop trail is an area overlooking a gulch full of native wet montane trees and shrubs — natural Hawaiian honeycreeper bird feeders. Keep a lookout for ‘Amakihi, ‘Apapane, and ‘I’iwi taking nectar from the flowering ‘Ohia trees with their red pompom-like lehua (flowers) and yellow flowers of the endemic Mamane trees. — Lance Tanino
