Lower Puna, Hawaii Island, bird and habitat surveys of 2003 and 2016 Lower Puna, Hawaii Island, bird and habitat surveys of 2003 and 2016
The newly identified rapid ohii death (ROD; Metrosideros polymorpha) originated in the lower Puna district and its distribution has spread across Hawaii Island. As ROD expands it is expected that the loss of the dominant tree species will adversely affect bird populations. This project is a first attempt to describe the relationship between the impacts of ROD on the Hawaiian avifauna...
Summary of soil field-saturated hydraulic conductivity, hydrophobicity, preferential-flow, and particle-size measurements collected at four research sites on the island of Maui, Hawaii, September 2017-August 2018 Summary of soil field-saturated hydraulic conductivity, hydrophobicity, preferential-flow, and particle-size measurements collected at four research sites on the island of Maui, Hawaii, September 2017-August 2018
The U.S. Geological Survey and the University of Hawaii at Manoa, in cooperation with the County of Maui Department of Water Supply and the State of Hawaii Commission on Water Resource Management, initiated a field data-collection program to provide information for evaluating how infiltration rates and soil hydrophobicity are dependent on plant species type within forested areas on the...
Hawaii Volcanoes National Park Elepaio nest monitoring and black rat mark recapture data 2015-2017 Hawaii Volcanoes National Park Elepaio nest monitoring and black rat mark recapture data 2015-2017
In Hawaii and other oceanic islands with few native land mammals, black rats (Rattus rattus) are among the most damaging invasive vertebrate species to native forest bird populations and habitats, due to their arboreal behavior and generalist foraging habitats and habitat use. We evaluated the nesting response of Hawaii Elepaio (Chasiempis sandwichensis; Monarchidae), a generalist...
Hawaii Island biodiversity trends across time and space, 1977 and 2015 Hawaii Island biodiversity trends across time and space, 1977 and 2015
These are the datasets for the Hawaii Forest Bird Survey (HFBS) and the Hawaiian Biodiversity Trends Across Time and Space project that systematically characterized plant and bird communities. The HFBS sampled from 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)...
Molokai (Kawela) USGS ridge-to-reef vegetation monitoring study 2009-2014 Molokai (Kawela) USGS ridge-to-reef vegetation monitoring study 2009-2014
This data release contains two files: 1) the raw data collected as part of a vegetation monitoring study that was conducted to assess the changes in plant species frequency inside and outside a fenced exclosure, constructed to eliminate browsing and grazing by feral goats, from 2009-2014 in the US Geological Survey's Kawela research site on the island of Molokai, Hawaii. 2) A list of...
Hawaii Volcanoes National Park Plant Reproductive and Rat Abundance Data 2016-2017 Hawaii Volcanoes National Park Plant Reproductive and Rat Abundance Data 2016-2017
This data included data and metadata on 1) the number of open fruit of Hibiscidelphus giffardianus, 2) Mark recapture data for rats, 3) location data for rat traps within plots and 4) seedling count data for Hibiscidelphus giffardianus. All sites were within Hawaii Volcanoes National Park. This study aims to evaluate the effect of rat population control on the ability of Hibiscadelphus
Oahu multi-state occupancy models of foraging habitat use by Hawaiian hoary bats 2017 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).
Hawaii Island Hoary Bat Acoustic and Visual Surveys 2014 Hawaii Island Hoary Bat Acoustic and Visual Surveys 2014
Hawaiian hoary bat vocalization and visual detection records collected on Hawaii Island, Hawaii, September-October 2014. Bat echolocation was monitored with ultrasonic detectors and bat occurrence and behavior was monitored using thermal surveillance cameras.
Pedestrian tsunami evacuation results for two tsunami-inundation zones (2009 and probable maximum tsunami (PMT)) and four travel speeds (slow walk, fast walk, slow run, and fast run) for American Samoa Pedestrian tsunami evacuation results for two tsunami-inundation zones (2009 and probable maximum tsunami (PMT)) and four travel speeds (slow walk, fast walk, slow run, and fast run) for American Samoa
This data release is comprised of a set of eight time travel map shapefiles (two tsunami inundation zones and four travel times) for use in GIS software applications and two population exposure by travel time tables (residents and nonresidences) for use in GIS software applications and other standalone spreadsheet applications. The travel time map was generated using the Pedestrian...
Hakalau Bioacoustic Surveys and Models 2015 Hakalau Bioacoustic Surveys and Models 2015
In this study, we create and evaluate a protocol to estimate the density, which can be used to estimate the abundance of terrestrial sound-producing animals from single automatic sound recorders. The protocol uses cue rates from the target species as well as sampling conditions and an estimate of the distance of the individual to the recorder based on the power of the sound. We applied...
Northwestern Hawaiian Islands Sea-level Rise Scenarios and Models 2010-2015 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...
Northwestern Hawaiian Islands: Impacts to Avifauna from the Tohoku Tsunami 2011 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...
