Northwestern Hawaiian Islands: Impacts to Avifauna from the Tohoku Tsunami 2011

This collection of nine datasets covers Midway Atoll and Laysan Island in the Northwestern Hawaiian Islands, and was created to help estimate the impacts of the March 11, 2011 tsunami event on avifauna in the Northwestern Hawaiian Islands.

Northwestern Hawaiian Islands Sea-level Rise Scenarios and Models 2010-2015

This data release consists of two ESRI geodatabases that store inundation areas for various future scenarios of sea-level rise, groundwater rise, and storm waves for Laysan Island and Midway Atoll in the Northwestern Hawaiian Islands.

HAVO Montane Ohia Diameter and Cavity Data 2017

We quantified the availability of breeding habitat of the endangered Hawaiian Akepa (Loxops coccineus). 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.

Projected inundation on Laysan Island, resulting from various scenarios of sea-level rise, groundwater rise and storm waves

This dataset (in ESRI file geodatabase format) contains inundation areas for various future scenarios of sea-level rise (SLR), groundwater rise, and storm waves at Laysan Island in the Northwestern Hawaiian Islands. Five types of inundation scenarios are considered: (1) passive SLR, (2) passive SLR including groundwater rise, (3) wave-driven inundation during storm events, (4) wave-driven...

Oahu multi-state occupancy models of foraging habitat use by Hawaiian hoary bats 2017

This data release consists of a single table that includes sample site geographic locations, insect prey abundance, and bat activity and behavior metrics. The dataset was used to develop multi-state occupancy models of foraging habitat use by Hawaiian hoary bats (Lasiurus cinereus semotus).

Occurrence of natural nest cavities in montane ohia trees in Hawaii Volcanoes National Park

We quantified the availability of breeding habitat of the endangered Hawaiian Akepa (Loxops coccineus).

Hawaiian Islands Hawaiian Hoary Bat Genetic Sexing 2009-2016

We tested the utility of a protocol using genetic markers that previously proved successful to identify the sex of Vespertilionid bats on tissues collected from live bats and carcasses of varying age from the Hawaiian hoary bat (Lasiurus cinereus semotus). This molecular method is based on genes unique to X and Y chromosomes in mammals and previously was used successfully on North American...

Hawaii Land Cover and Habitat Status

These two raster data layers depict the land cover and degree of human disturbance to plant communities on the seven main Hawaiian Islands, and were developed as part of a comprehensive USGS assessment of carbon sequestration potential by natural ecosystems in the State of Hawaii.
