Hawaii Habitat Quality (HI_HabQual) This layer depicts the status, or degree of disturbance, to plant communities on the main Hawaiian Islands. To more precisely identify areas where native species may presently be found, a map was generated that considers the following three categories of habitat quality: High, areas dominated by native vegetation; Medium, areas dominated by nonnative vegetation; and Low, highly modified landscapes. The primary source for mapping these three categories is the HIGAP land-cover classification (Gon, 2006). The High category includes all HIGAP land-cover classes that are considered to be either native dominated or mixed native and nonnative in order to represent those areas that have substantial native-species composition....

The study area covers approximately 486 ha of marine waters and terrestrial coastal plains. Nocturnal aerial insect collection occurred in January and April (2 or 3 nights each) and in July and November (1 or 2 nights each) in 2014. Insects were collected at three stations (KAHO1, KAHO3, KAHO4) between 1 and 10 m above sea level. Nocturnal aerial insects were collected using a 22 W UV light placed above a funnel and bucket trap (Model #2851M, Bioquip Products...

One measure of the potential for water to cause corrosion is the Langelier Saturation Index (LSI) (Langelier, 1936). The LSI is a measure of the potential for water to deposit a mineral layer (scale) within a water distribution system that can inhibit the corrosion of pipes and joints. Negative values of LSI suggest mineral deposition is not likely to occur while positive values indicate conditions favorable to mineral deposition. Negative values of LSI might be indicative of conditions that lead to elevated concentrations of metals, such as lead...

This dataset includes hourly percentages of specific incubation behaviors (i.e. inactivity, vigilance, preening, and nest maintenance) from ~230 video-monitored nest days across 83 nests (18 in 2010, 30 in 2011, and 35 in 2012).

Four types of inundation scenarios are considered: (1) passive SLR, (2) passive SLR including groundwater rise, (3) wave-driven inundation during storm events, and (4) wave-driven inundation during storm events including groundwater rise. For each of these four scenarios, five different levels of SLR are considered: 0.00 m, +0.50 m, +1.00 m, +1.50 m, and +2.00 m. We considered each scenario at mean high water in order to predict inundation during the more damaging part of the tidal range. Each of the...

The travel time analysis uses ESRI's Path Distance tool to find the shortest distance across a cost surface from any point in the hazard zone to a safe zone. This cost analysis considers the direction of movement and assigns a higher cost to steeper slopes, based on a table contained within the model. The analysis also adds in the energy costs of crossing different types of land cover, assuming that less energy is expended walking along a road than walking across a sandy beach.

The species is thought to nest excusively in natural cavities within mature ohia (Metrosideros polymorpha) trees but birds commonly occur in short stature trees that presumably do not have any natural cavities because of their polyploidal (many-branched) structure. To test this hypothesis we searched for cavities in trees where akepa forage and we measured diameter of each stem of each tree examined. The habitat is in montane areas of Hawaii Volcanoes National Park on Mauna Loa volcano.We surveyed 57 plots, 49 in montane woodland and 8 in closed-canopy forest. Six tree cavities were detected in the 214 sampled trees:...

The study area covers approximately 486 ha of marine waters and terrestrial coastal plains. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations between 1 and 10 m above sea level, that operated nightly from November 2013 through February 2015.
