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...

In 1976-1981, the U.S. Fish and Wildlife Service conducted systematic surveys of forest birds and plant communities on all of the main Hawaiian Islands as part of the Hawaii Forest Bird Surveys (HFBS; Scott, J.M., S. Mountainspring, F.L. Ramsey, and C.B. Kepler. 1986. Forest bird communities of the Hawaiian Islands: their dynamics, ecology, and conservation. Studies in Avian Biology 9:1-431). Results of this monumental effort have guided conservation efforts and provided the basis for many plant and bird recovery plans and land acquisition decisions in Hawaii during the past two decades. Unfortunately, these estimates and range maps are now seriously outdated, hindering modern conservation decision-making efforts...

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 dataset describes the boundary of the study area used to analyze regeneration and change in status of native ohia forests in the wet habitat on the eastern side of the island of Hawaii. This area includes forests that were heavily impacted by landscape-level canopy dieback in the 1970s as well as forests that were not affected with tree canopy death or defoliation.

This shapefile describes the canopy status and distribution of of ohia (Metrosideros polymorpha) forests on the eastern side of the island relative to a landscape-scale canopy dieback that impacted this area in the 1970s.

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 collection of nine datasets covers Midway Atoll and Laysan Island in the Northwestern Hawaiian Islands, and was created to help estimate the impacts of the March 11, 2011 tsunami event on avifauna in the Northwestern Hawaiian Islands. For each island, we generated a coastline dataset and a land cover dataset based on satellite imagery taken the year before the tsuanmi event. We also created datasets of the inundation extent during the tsunami event based on GPS track files of the high water mark, taken by staff scientists stationed on the islands at the time of the tsunami. Additionally, nest distribution data were collected for black-footed albatrosses (Phoebastria nigripes) at Midway Atoll.

Climate change in Hawaiʻi is expected to result in increasing temperatures and varying precipitation through the twenty-first century. Already, high elevation areas have experienced rapidly increasing temperatures and there has been an increase in the frequency of drought across the Islands. These climatic changes could have significant impacts on Hawaiʻi’s plants and animals. Changes in temperature and moisture may make current habitat no longer suitable for some species, and could allow invasive species to spread into new areas. Hawaiʻi Volcanoes National Park is home to 23 species of endangered vascular plants and 15 species of endangered trees. Understanding how climate change may impact the park’s plants...
