Subalpine shrubland and alpine aeolian ecosystems occur throughout Hawaii and represent important habitats for native species. On Maui, shrubland and alpine ecosystems occur in and around Haleakala National Park (HALE) on the mountain's upper west slope, upper south slope, and within the crater. During 2001-2004 an inventory of arthropods was conducted on the upper west slope and summit of Haleakala National Park, using three systematic sampling techniques and limited opportunistic hand collecting. This report catalogues all arthropod species collected in the course of the inventory, and when possible, provides additional information relevant to the species listed. In addition, inventory completeness and the relative effectiveness of the different sampling techniques are accessed.

Haleakala National Park (HALE) is host to 9 species of honeycreeper, five of which are endangered. The Maui Parrotbill and Akohekohe were once found in low elevation habitats on east Maui, but are now restricted to mesic and wet forests above 1,100 m. The Maui akepa prefers mature ohia and ohia-koa above 1,500 m. The last visual detection of the Maui akepa was at 1,872 m in Kipahulu Valley to the east of Kaapahu in 1995. However, auditory detections require visual confirmation because Maui Akepa songs can be confused with songs of Maui Parrotbills. The Maui Nukupuu was in Hanwi Natural Area Reserve at 1,890 m on the northern slope of Haeakala in 1995. Further survey efforts have yielded no additional detections. The Poouli was discovered in 1973 and was confined to a single location in wet ohia forest above 1,500 m in Haleakala. As of 2005, only two individuals are known to exist, however, the Maui Forest Bird Recovery Project reports that the last Poouli has not been sighted within the last year.

This data describes a presence- absence survey for alien mammals in Kaapahu area of Haleakala National Park (HALE). Signs of mammals, as well as trapped mammals, were documented in database and included location, sign type, trap type, necropsy information, and station locations.

In 2003, the National Park Service acquired 46,943 ha of Kahuku Ranch, in the Ka'u district of Hawai`i. This addition to Hawai`i Volcanoes National Park includes a diverse assemblage of vegetation communities. Since little was known about the communities and their floristic composition, appropriate management practices could not be developed. Surveys conducted between 2004 and 2006 in Kahuku described vegetation communities and located rare, threatened and endangered plants, as well as disruptive alien weeds. Forty-one kilometers of transects and 177 vegetation plots were ground-surveyed, and 6.5 hours of helicopter surveys were conducted. Surveys encountered a total flora of 455 vascular plant species, of which 40% were native. Five endangered, one threatened, one candidate endangered, and seven species of concern were found, as well as 26 locally rare native species. Forty-three disruptive alien plant taxa in and near Kahuku were mapped. Several sites containing high numbers of either rare or invasive plants were identified.

Eight-minute point-transect distance bird surveys were collected in and around Haleakala National Park from 1993-2008. This dataset contains the location, species, and distance to detected birds, as well as identifying initials to distinguish among observers.

Between 2002 and 2004, a vegetation survey was completed. The results of this inventory provide a checklist for the area. This database supplies the checklist for Kaapahu, Haleakala National Park (HALE).
