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...
Bird banding at 2 locations adjacent to one another (one in koa restoration forest, and other in native intact forest) at Hakalau Forest National Wildlife Refuge before and after the start of an outbreak by koa moths (Scotorythra paludicola) during 2013. Each bird was measured with an electronic scale accurate to 1/10th g. Results indicate that insectivorous birds increased in mass, on average, while generalist diet species showed marginally significant increases, and two out of three nectarivorous and frugivorous birds did not have significant change.

Surveys for immature life stages of Papilio godeffroyi were conducted on 117 individually marked host trees (Micromelum minutum) in eight forest stands on Tutuila Island, American Samoa, at approximately monthly intervals during 2013-2014. The eight stands were mostly in or adjacent to the National Park of American Samoa (NPSA), but one site was sampled near the western tip of Tutuila, outside NPSA. Papilio life stages included eggs, eggshells, larvae, pupae, and exuviae, which were taken to the laboratory at American Samoa Community College for examination and processing. Specimens were reared (live specimens) or assessed (dead or inert specimens) to determine their reproductive outcome and rates of parasitism....

Hawaii Volcanoes National Park Elepaio nest monitoring and black rat mark recapture data 2015-2017
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...
