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.

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.

As part of a larger study looking at the seasonal distribution and relative abundance of the southern house mosquito Culex quinquefasciatus in Kīpahulu Valley, Haleakalā National Park, terrestrial and stream surveys were conducted to determine the abundance of available larval mosquito habitat and the presence of mosquito larvae within the study area. Terrestrial larval mosquito habitat, like wallows and hapuu cavities, are largely dependent on the presence of feral pigs. Naturally occurring ground pools may be found in bogs and on less permeable, older soils. Stream-associated habitat is dependent more on rocky substrates and stream flow. First order, intermittent flowing streams found at higher elevations are more likely to provide larval habitat. At the higher elevation Palikea site only Aedes japonicus were found in stream pools but at the lower Delta site both Aedes japonicus and C. quinquefasciatus were found in stream pools. Culex quinquefasciatus larvae were also found in a ground pool with the remains of a dead pig at the Delta site.

The Hawaii Forest Bird Survey (HFBS) systematically characterized plant and bird communities across transects spanning all major Hawaiian Islands except O‘ahu. This extensive dataset has now been organized into a database and associated geographic information system (GIS) layers. This baseline provides an opportunity to assess how forest ecosystems and their constituent bird and plant populations have changed over time. As part of the HaBiTATS (Hawaiian Biodiversity Trends Across Time and Space) project, a select area on Hawai‘i Island was surveyed in 2015 with the objective of demonstrating the potential of using the HFBS methodology to reassess the status of bird and plant communities across multiple geographic regions and islands. The results of the comparative study presented herein highlight examples of the apparent vulnerability and resiliency of native-dominated Hawaiian ecosystems. Specific study objectives were to: (1) collect information on plant and bird species community composition, abundance, and spatial distribution following the original HFBS methodology; (2) assess changes in several biodiversity metrics; (3) examine changes in the distribution of invasive non-native species as well as changes in land use as potential drivers of native biodiversity patterns, and (4) demonstrate field and data analysis methods that may be applied to a large-scale biodiversity monitoring program. This is the vegetation species dataset from 1977.

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).
