Judge, S.W., Camp, R.J., Sedgwick, D.E., Squibb, C.L., and Hart, P.J., 2017, Landbird survey bird and habitat data collected in Hawaii Volcanoes National Park during 2015 and 2016: U.S. Geological Survey data release,


Hawaiʻi 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 every five years. The entire survey area was comprised of eight tracts in forest, woodland, and shrub habitat, totaling 26,364 ha. Each tract was surveyed using point-transect distance sampling to calculate estimates of bird abundance and density. In addition to the permanent PACN survey transects, randomly generated point-transects were also surveyed, [...]

The National Park Service (NPS) created the Inventory and Monitoring (I&M) Program following the National Park Omnibus Management Act of 1998 to acquire data needed to support effective management and protection of native habitats located on park lands. The role of the I&M Program is to collect, organize, and make available natural resource data and contribute to the National Park Service’s institutional knowledge by facilitating the transformation of data into information through analysis, synthesis and modeling ( In concordance with the stated role of the Pacific Island Network (PACN) I&M Program, the objectives of this survey were to provide information for monitoring long-term trends in habitat in HAVO. Ultimately, this information will help to inform and implement management actions to conserve native bird and plant populations.
