In Hawai‘i 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. This is a selected data set used to assess the impacts of rodenticide treatment on black rat (Rattus rattus) abundance within Hawaii Volcanoes National Park (HAVO). The key objective was to identify rat abundance before and after rodenticide treatment, using paired non-treatment and treatment plots at high elevation (1700-1830m) and low elevation (1220-1340 m). This dataset includes the results of a mark recapture study that took place within...

In Hawai‘i 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 Hawai‘i ‘Elepaio (Chasiempis sandwichensis; Monarchidae), a generalist insectivore, to the removal of black rats using rodenticide in a before-after-control-impact study in high and low, mesic montane habitat recovering from long-term damage from introduced ungulates and weeds. We monitored nesting and rat activity during 2015–2016 before applying diphacinone bait in 2017 to remove rats from two 700 x...

These data are microgravity measurements collected at the summit of Kilauea Volcano, Hawaii. Data are collected using multiple instruments, with each file representing measurements from a specific instrument during a specific time period. The data dictionary explains the file format and contents, and the dataset will be updated as new measurements are collected.

This is a selected data set that outlines the plot areas and trapping grids used to monitor 'Elepaio and black rat activity within Hawaii Volcanoes National Park (HAVO) from 2015-2017. These data provide the spatial reference and structure of four field plots used in the study. Please reference the associated metadata and datasets that correspond to this publication for more information on how these locations were used.

This is a selected data set used to assess the impacts of rodenticide treatment on black rat (Rattus rattus) abundance within Hawaii Volcanoes National Park (HAVO). The key objective was to identify rat density in native habitat in the Mauna Loa Strip section of HAVO before and after rodenticide treatment, using a paired non-treatment and treatment plot for comparison in a before-after, control-impact (BACI) study design. These data are part of larger work describing the response of native species to rat control. This data set includes the results of the mark recapture study that took place during two different trapping periods (before and after treatment) within a centralized 300x300 m (9 ha) portion of each 700x700...

We evaluated the nesting response of Hawai‘i ‘Elepaio (Chasiempis sandwichensis; Monarchidae), a generalist insectivore, to the removal of black rats using rodenticide in a before-after-control-impact study in high and low, mesic montane habitat recovering from long-term damage from introduced ungulates and weeds. We monitored nesting activity during 2015–2016 before applying diphacinone bait in 2017 to remove rats from two 700 x 700-m treatment plots that were paired with two non-treatment plots. We continued monitoring through July 2017. This data set includes a summarized account of Elepaio nests during the 2015, 2016, and 2017 breeding seasons. There is a unique identifier for each nest ('NestID '), along with...

This is a selected data set that outlines the plot areas used to assess the impacts of rodenticide treatment on black rat (Rattus rattus) abundance within Hawaii Volcanoes National Park (HAVO). These data provide the spatial reference for a larger work describing the response of native species to rat control. Included are the corner boundaries for the 700x700 m (49 ha) study plots and each grid point/station within the centralized 300x300 m (9 ha) sub-plot at both the treatment and non-treatment site. Traps were placed 50 m apart, one at each station in the trapping grid, for a total of 49 traps in each of the sub-plots. The rodenticide treatment and native species monitoring were conducted using the entire 49 ha...
