HAVO Montane Ohia Diameter and Cavity Data 2017 HAVO Montane Ohia Diameter and Cavity Data 2017
We quantified the availability of breeding habitat of the endangered Hawaii Akepa (Loxops coccineus). The species is thought to nest excusively in natural cavities within mature ohia (Metrosideros polymorpha) trees but birds commonly occur in short stature trees that presumably do not have any natural cavities because of their polyploidal (many-branched) structure. To test this...
Hawaii Volcanoes National Park Landbird Surveys 2015-2016 Hawaii Volcanoes National Park Landbird Surveys 2015-2016
Hawai`i Volcanoes National Park (HAVO) was surveyed for landbirds and landbird habitat from February through April 2015 and February through April 2016. This information provides the second datum in the time-series of Pacific Island Network (PACN) monitoring for long-term trends in landbird distribution, density, and abundance. Initial PACN surveys were conducted in 2010 and are repeated...

Using distance sampling with camera traps to estimate densities of ungulates on tropical oceanic islands Using distance sampling with camera traps to estimate densities of ungulates on tropical oceanic islands
Reliable population estimates are one of the most elementary needs for the management of wildlife, particularly for introduced ungulates on oceanic islands. We aimed to produce accurate and precise density estimates of Philippine deer (Rusa marianna) and wild pigs (Sus scrofa) on Guam using motion-triggered cameras combined with distance sampling to estimate densities from observations...

2022–2024 Status and trends of the Palila (Loxioides bailleui) 2022–2024 Status and trends of the Palila (Loxioides bailleui)
Palila (Loxioides bailleui) are critically endangered Hawaiian honeycreepers specializing on the seedpods of māmane (Sophora chrysophylla) and restricted to Mauna Kea volcano on the Island of Hawaiʻi. A previous analysis of survey data estimated an 89% population decline between 1998 and 2021. Using the most recent annual survey data from 2022, 2023, and 2024, we report updated annual...

Population trends of native and non-native forest birds on the island of Molokai, Hawaii Population trends of native and non-native forest birds on the island of Molokai, Hawaii
Hawaiʻi’s avifauna has undergone profound changes over the past 1,000 years, with many endemic bird species driven to extinction and non-native introductions reshaping forest ecosystems. On the island of Molokaʻi, habitat degradation and the introduction of mosquito-borne disease, mainly avian malaria (Plasmodium relictum), have caused extinctions and severe declines in native forest...

Counting the chorus: A bioacoustic indicator of population density Counting the chorus: A bioacoustic indicator of population density
Passive acoustic monitoring has grown in utility for tracking wildlife populations, although challenges remain when using acoustic detections to monitor population size and density. Distance sampling is considered the ‘gold standard’ for estimating animal densities but has several important limitations, especially for rare, cryptic, and high-density species. Here, we test the performance...

Forest bird population status on Saipan, a small oceanic island Forest bird population status on Saipan, a small oceanic island
Tropical oceanic islands are critical biodiversity hotspots where population monitoring can help to determine the status and trends of rare and endangered species. Saipan is the second largest island in the Mariana Islands and contains many endemic and range-restricted bird species. Surveys of forest birds were conducted on Saipan using point-transect distance sampling, starting in 1982...

Power analysis of water quality of standing water bodies in the Pacific Island Network, 2009–2017 Power analysis of water quality of standing water bodies in the Pacific Island Network, 2009–2017
The National Park Service (NPS) Inventory and Monitoring Division (IMD) aims to provide data on park ecosystems' health to guide management decisions. Since 2007, NPS IMD has monitored water quality in marine areas, streams, anchialine pools, wetlands, and lakes in the Pacific Island Network (PACN) national parks. To maintain long-term monitoring program efficiency, protocols are...
