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 giffardianus to successfully establish seedlings. We compared H. giffardianus fruiting and recruitment in a stand treated for rats and a neighboring control stand. The study was conducted in two neighboring kīpuka, Kīpuka Puaulu and Kīpuka Kī, which are patches of well-developed forest surrounded by more recent lava flows. These kīpuka...

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...

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...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete.
