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 (SLR), groundwater rise, and storm waves for Laysan Island and Midway Atoll 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,

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. For each island, we generated a coastline dataset and a land cover dataset based on satellite imagery taken the year before the tsuanmi event. We also created d

HAVO Montane Ohia Diameter and Cavity Data 2017

We quantified the availability of breeding habitat of the endangered Hawaii 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. To test this hypothesis we searc

Channel Island Grazer Removal Data 2004-2016

This data includes data and metadata of (1) the percent cover of all species found along transects on the south facing slopes of Santa Cruz Island, CA (2) the height of all shrub individuals on transects on the south facing slopes of Santa Cruz Island, CA and (3) location data of on the south facing slopes of Santa Cruz Island, CA. Data were used in the analysis for the Manuspcript "Long-term impa

Hawaiian Islands Coastal Vegetation Survey 2013-2015

This dataset provides information on the current status and various other habitat and descriptive attributes of the native coastal vegetation for seven of the main Hawaiian Islands (i.e., does not include Niihau). This study was focused on identifying sites that still retain relatively intact and highly diverse native coastal plant communities throughout seven of the main Hawaiian Islands (Kaua

Hawaii Volcanoes National Park Landbird Surveys 2015-2016

Hawai`i Volcanoes National Park (HAVO) was surveyed for landbirds and landbird habitat from February through April 2015 and February through April 2016. This information provides the second datum in the time-series of Pacific Island Network (PACN) monitoring for long-term trends in landbird distribution, density, and abundance. Initial PACN surveys were conducted in 2010 and are repeated every fiv

Kanakaleonui Bird Corridor Montane Plants 2016

Montane plant communities throughout the world have responded to changes in precipitation and temperature regimes by shifting both margins and core distributional ranges upward in elevation. Continued warmer, drier climate conditions have been documented and are predicted to increase in high-elevation areas in Hawaii, consistent with climate change effects reported in other environments throughout
