Data

This data release includes metadata and tabular data that documents counts of shrimp and measurements of field variables aimed to identify factors that affect the distribution and abundance of the uncommon anchialine pool shrimp Metabetaeus lohena at Kaloko-Honokōhau National Historical Park during 2017. The data set documents biological, chemical and physical attributes within 173...

This data release contains a comma-delimited ascii file of seven same-day, discrete discharge measurements made at sites along selected reaches of Waikoloa Stream, Hawai'i on May 23, 2024. These discrete discharge measurements form what is commonly referred to as a “seepage run.” The intent of the seepage run is to quantify the spatial distribution of streamflow along the reach during...

These data were collected as part of several studies or efforts to remove brown treesnakes (Boiga irregularis) across three sites located in Guam, USA and one site in Cocos Island (Dano), Guam, USA. The various goals of projects were distinct and these data were applied to a more intensive, cross site comparison on the height snakes were detected during visual surveys as a function of...

The Yǻyaguak (Mariana Swiftlet; Aerodramus bartschi) is an endangered cave-roosting species native to Guam and southern Mariana Islands, Micronesia. On May 24-25, 2023, Guam was hit by the category-4 Typhoon Mawar, which brought wide-spread destruction to the island. Approximately 6 weeks prior to the typhoon in April 2023 we conducted surveys of the three known colonies of Yǻyaguak at...

These shapefiles represent the frequency characteristics of soil moisture, evapotranspiration, and climatic water deficit for Kauaʻi, Oʻahu, Molokaʻi, Maui, and the Island of Hawaiʻi for a set of water-budget scenarios that characterize unique combinations of rainfall and land-cover conditions. Four water-budget scenarios were developed to quantify the effects of drought on soil moisture...

These shapefiles represent the spatial distribution of mean annual groundwater recharge, in inches, for Kauaʻi, Oʻahu, Molokaʻi, Maui, and the Island of Hawaiʻi for a set of water-budget scenarios that characterize unique combinations of drought and land-cover conditions. Two water-budget scenarios were developed to quantify the effects of severe drought and future climate conditions on...

Resource managers and users seek information that can be used to balance the needs of competing uses of groundwater and streamflow in the Heeia watershed, Oahu. A previously constructed steady-state numerical groundwater-flow model for the island of Oahu, Hawaii (https://doi.org/10.3133/sir20205126) using MODFLOW-2005 with the Seawater Intrusion (SWI2) package was used to examine the...

This is a dataset containing the first and second record of georeferenced observations of introduced and invasive vascular plant species in the contiguous United States (CONUS). Non-native plant species were identified using the United States Register of Introduced and Invasive Species (US-RIIS) list. After identifying a list of plants non-native to CONUS, we obtained presence data from...

This dataset comprises high-resolution geotif files representing various aspects of the ʻākohekohe (Palmeria dolei) potential habitat on the Island of Hawaiʻi. It includes a habitat suitability map showing average suitability scores, a map of homogenous forested areas (HFAs) depicting clusters with consistent suitability scores, and a map of pixel-wise standard deviation across habitat...

This data release includes metadata and tabular data documenting the reproductive demography of the Samoan swallowtail butterfly (Papilio godeffroyi), including rates of parasitism by two species of Ooencyrtus wasp. Data was collected at approximately monthly surveys of marked host trees (Micromelum minutum) at eight forest stands, mostly in or adjacent to the National Park of American...

These data represent brown treesnake (Boiga irregularis) captures from a population in a 5 ha natural snake enclosure on Guam from 2016 - 2023. During the period of study we artificially reduced the number of snakes present in the population through a variety of control tools that included toxic baits, as mice and chicks, live trapping, and hand capture. We censused the population...

The yǻyaguak (Mariana swiftlet; Aerodramus bartschi) is an endangered cave-nesting species historically found on Guam and the southern Mariana Islands, Micronesia. The population on Guam has been severely impacted by the introduction of the brown treesnake (Boiga irregularis). Population status assessments have, however, been challenging due to the limitations of traditional counting...
