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...

Arthropods are important prey for most forest birds in Hawaii. The relative abundance of arthropods on koa (Acacia koa) changed significantly during an outbreak of the koa moth (Scotorythra paludicola) that occurred across much of Hawaii Island during 2013-2014. The outbreak resulted in large tracts of koa forest becoming defoliated by large numbers of koa moth caterpillars. This data release includes metadata and tabular data that documents how bird diets changed at Hakalau Forest National Wildlife Refuge during the outbreak. The data set documents numbers of koa moth caterpillars and other arthropod prey consumed by forest birds prior to, and during the koa moth outbreak. Diets were reconstructed by identifying...
