This shapefile is the official boundary of the Hawaii Fish Habitat Partnership. The shapefile was developed in 2013 to reflect the boundary as defined by the Hawaii Fish Habitat Partnership, a recognized Fish Habitat Partnership (FHP) of the National Fish Habitat Partnership.
Hawai‘i’s endangered waterbirds have experienced epizootics caused by ingestion of prey that accumulated a botulinum neurotoxin produced by the anaerobic bacterium Clostridium botulinum (avian botulism; Type C). Waterbird carcasses, necrophagous flies, and their larvae initiate and spread avian botulism, a food-borne paralytic disease lethal to waterbirds. Each new carcass has potential to develop toxin-accumulating necrophagous vectors amplifying outbreaks and killing hundreds of endangered birds. Early carcass removal is an effective mitigation strategy for preventing avian intoxication, toxin concentration in necrophagous and secondary food webs, and reducing the magnitude of epizootics. However, rapid detection...

Introduction Potential offsite impacts to public and ecosystem health from exposure to current-use pesticides and other organic contaminants are a growing concern in Hawaiʻi. In response to these concerns, the U.S. Geological Survey (USGS), in cooperation with the State of Hawaiʻi Department of Agriculture (HDOA), initiated a comprehensive pesticide-monitoring program of surface water in Hawaiʻi in 2016. The State of Hawaiʻi Department of Health (HDOH) is collaborating by providing technical and scientific assistance. The objectives of the Hawaiʻi pesticide-monitoring program include (1) documenting the occurrence and distribution of current-use pesticides in surface water of geographically distinct agricultural...

This data release provides flooding extent polygons (flood masks) and depth values (flood points) based on wave-driven total water levels for 22 locations within the States of Hawaii and Florida, the Territories of Guam, American Samoa, Puerto Rico, and the U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands. For each of the 22 locations there are eight associated flood mask polygons and flood depth point files: one for each four nearshore wave energy return periods (rp; 10-, 50-, 100-, and 500-years) and both with (wrf) and without (worf) the presence of coral reefs. These flood masks can be combined with economic, ecological, and engineering tools to provide a rigorous financial valuation...

Acoustic sampling for occurrence of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus) was conducted at 18 "long-term" acoustic monitoring stations on 12 Hawaii Army National Guard (HIARNG) installations across the islands of Hawaii, Maui, Molokai, Oahu, and Kauai between 2012 and 2018. Hawaiian hoary bat insect prey sampling with paired acoustic monitoring was conducted at Keaukaha Military Reservation (KMR) on Hawaii Island from May to August, 2018. At this property, a herd of domestic goats (occasionally mixed with domestic sheep) were rotated among grazing plots as part of a weed control program managed by HIARNG. We sampled insect abundance and community within the area where goats were used for...
Kīlauea Point National Wildlife Refuge (KPNWR) is an important seabird breeding site located at the northeastern tip of Kauaʻi in the main Hawaiian Islands (MHI). Despite the regional significance of KPNWR as one of the most important breeding sites for Red-tailed Tropicbirds (Phaethon rubricauda), Red-footed Boobies (Sula sula), and Wedge-tailed Shearwaters (Ardenna pacifica) in MHI, robust and accurate population surveys have not been consistently conducted and recent information is lacking. In this study, we completed comprehensive population surveys for these three species during the 2019 breeding season. Using direct censusing methods (ground-searching, visual and photographic counts), we determined that 387...

This shapefile represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Kauai, Hawaii. The water-budget components in the shapefile were computed by a water-budget model for a scenario representative of recent conditions (1978–2007 rainfall and 2010 land cover), as described in USGS Scientific Investigations Report (SIR) 2015-5164. The model was developed for estimating groundwater recharge and other water-budget components for each subarea of the model. The model-subarea data set, consisting of 400,714 subareas (polygons), was generated using Esri ArcGIS software by intersecting (merging) multiple spatial data sets. Spatial datasets merged include those that characterize...

Mosquito-borne avian malaria is a key limiting factor on Hawaiian forest bird populations. Preservation of endemic forest birds and restoration of Hawaiian forest bird communities will rely on mosquito control. While landscape level control is being developed, managers need short term and reliable tools for monitoring and controlling mosquito populations to protect remaining breeding bird populations. As part of a larger study looking at the efficacy of the biopesticide VectoMax FG for control of larval Culex quinquefasciatus, USGS and DOFAW personnel monitored adult mosquitoes (Culex quinquefasciatus and Aedes japonicus) along the Kawaikoi Stream during late summer, September through November 2016 and 2017.

-- Methods -- The Weather Research and Forecast model (WRF) is applied to construct triply-nested meshes. The outermost domain (20-km horizontal resolution) is large enough to cover almost the whole tropical and subtropical areas from the central Pacific to the western Pacific. The intermediate domain has 4-km horizontal resolution, and the innermost domain of each individual island has a horizontal resolution of 0.8 km. The driving fields for the atmosphere are the NASA Modern-Era Retrospective Analysis for Research and Applications reanalysis, and the sea surface temperature (SST) is from NOAA. Variables in the driving fields include temperature, wind, geopotential height, water vapor, etc. For the future runs,...
During 13-18 May, 2019, we censused red-footed boobies (Sula sula) at Kīlauea Point National Wildlife Refuge (KPNWR), Kauaʻi. To evaluate ground-based visual counts and assess variability among methods, we employed photographic techniques to count nesting red-footed boobies at KPNWR in three distinct sub-colony areas: Crater Hill East, Crater Hill Interior, and Crater Hill West (see associated data series report for delineation of sub-colony areas). For ground-based photos, we used a Sony a7rii camera (42 megapixel full-frame) equipped with a Sony 100-400mm F4.5-5.6G lens to allow sufficient resolution to count nests and birds. We achieved pixel resolutions (as a function of camera resolution, focal length, and...
Because federal, state, and local resource managers lack comprehensive, easily available data to map current seabird colony locations and breeding population sizes throughout the main Hawaiian Islands, the USGS Western Ecological Research Center, with support from the Bureau of Ocean Energy Management, is working with many partners to generate an Atlas of Breeding Seabirds of the Main Hawaiian Islands. The atlas will provide benchmarks to measure future changes in seabird population sizes and breeding distribution and will also assist efforts to evaluate threats to seabirds both on land and at sea. Ultimately, species- and colony-specific data for main Hawaiian Island seabirds on land and at sea will inform evaluations...
We used a stratified-random sampling approach to estimate the total abundance of Wedge-tailed Shearwater (Ardenna pacifica) nest sites across Kīlauea Point National Wildlife Refuge (KPNWR), Kauaʻi, during 1-7 July 2019. We first identified strata as unique geographic areas of the refuge to account for potential differences in nesting habitat and non-uniform nest site clustering. We then sub-divided strata where we expected high, low, minimal, or no nest site abundance. These distinctions were based on knowledge of shearwater nesting distribution gained while performing extensive ground-searching for tropicbirds across the entire refuge in April and May 2019. We delineated strata boundaries using recent satellite...
