Guam, USGS Closed Population (NWFN) data relating to brown treesnake and prey interactions processed into monthly intervals from 10/2016 - 2/2023

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 intensively duri

Guam, Mariana swiftlet counts, 2019-2023

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 methods, whic

High-Resolution Land Cover Maps of Lāna‘i, Hawai‘i, 2020

This dataset provides high-resolution, species-specific land cover maps for the Hawaiian island of Lāna'i based on 2020 WorldView-2 satellite imagery. Machine learning models were trained on extensive ground control polygons and points. The land cover maps capture the distribution and diversity of vegetation with high accuracy to support conservation planning and monitoring. This data release cons

Kauaʻi Rapid ʻŌhiʻa Death (ROD) Ambrosia Beetles 2020-2021

This data release includes data and metadata containing documentation of 1) ambrosia beetle (Coleoptera: Curculionidae) species caught in cross-vane panel traps (CVPT) in ʻōhiʻa (Metrosideros polymorpha) dominated forests with geographical locations and elevations and 2) ambrosia beetle species reared directly from cut ʻōhiʻa tree sections (bolts) infected with Rapid ʻŌhiʻa Death (ROD)-causing pat

Island of Hawaii bird, mosquito, and avian malaria infection data 2001-2004

This data publication contains data files collected as part of a field, laboratory, and modeling effort aimed at uncovering ecological drivers of avian malaria transmission and impacts on Hawaiian honeycreepers across an elevational gradient on the eastern flank of Mauna Loa and Kilauea volcanoes on Hawaii Island. From 2001-2004, mosquito and bird data were collected at nine sites ranging 25 to 1,

Cocos Island, Guam Brown Treesnake Rapid Response Visual Survey and Capture Data, 10/2020 - 05/2023

These data were generated during a USGS Rapid Response for brown treesnakes (Boiga irregularis) on Cocos Island Guam (Islan Dåno’, Guåhan in CHamoru). They represent data collected during nocturnal visual surveys for brown treesnakes and data associated with captured snakes, effort during visual surveys as time and distance, as well as lizards, birds, and bats encountered during transect surveys.

Guam, USGS Closed Population (NWFN), an experimental eradication of brown treesnakes in a 5-ha study site, 2016 - 2023

These data represent a case study on managing the invasive brown treesnake (Boiga irregularis) on Guam within a 5 ha snake enclosure located on Northern Guam. The site code (NWFN or North West Field North) reflects a location on Andersen Air Force Base, Northern Guam, which has been a study site for close to two decades. The experimental process followed an adaptive resource management process to

Model subareas and moisture zones used in a sensitivity analysis of a water-budget model completed in 2022 for the islands of Oahu and Maui, Hawaii

A sensitivity analysis of groundwater-recharge estimates from a water-budget model was completed for the islands of Oahu and Maui, Hawaii (Johnson and others, 2023). Results of the sensitivity analysis were used to quantify the relative importance of selected model parameters to recharge estimates for three moisture zones (dry, mesic, and wet) on Oahu and Maui. These shapefiles contain the boundar

Seepage Runs of Hālawa Stream, Oʻahu, Hawaiʻi: December 2021 - June 2022

This data release contains four seepage runs conducted along selected reaches of South Hālawa Stream, North Hālawa Stream, and Hālawa Stream, Oʻahu, Hawaiʻi between December 2021 and June 2022. The data release has four child items that each consist of the following files: (1) a metadata xml file describing the child-item files and data attributes, (2) an annotated map showing the seepage-run meas

Hawaiʻi Volcanoes National Park plant cover, seedling, and plot description data, 2019

This data release includes data and metadata on plant and substrate cover, seedling counts, canopy cover, burn severity, and location information for plots that were established to monitor the efficacy of post-fire seed addition in Hawaiʻi Volcanoes National Park on the Island of Hawaiʻi.

Hawai‘i Island ʻōpeʻapeʻa (Hawaiian hoary bat; Lasiurus semotus) mist netting effort, capture, and tag retention, 2018–2021

‘Ōpe‘ape‘a (Hawaiian hoary bats; Lasiurus semotus) were surveyed at 23 sites on Hawaiʻi Island from 33 to 2,341 m elevation from May 2018 to August 2021. Of the 23 sites, 8 were established as fixed survey sites for sampling at repeated intervals from January 2019 through January 2021. We surveyed each fixed site at least once per four-month period (January–April, May–August, September–December),

Hawaiʻi Island ʻōpeʻapeʻa (Hawaiian hoary bat) roost data, 2018–2021

Hawaiian hoary bats ('ōpe'ape'a; Lasiurus semotus) were captured and tracked back to roosting locations on Hawaiʻi Island from 2018-2021. We examined resource selection at multiple spatial scales - perch location within a roost tree, roost tree, and forest stand. We used a discrete choice modeling approach to investigate roost selection and describe attributes of day-roost trees including those us
