Three Pacific Island Network parks were surveyed for landbirds and landbird habitat in order to provide information for monitoring long-term trends in forest bird distribution, density, and abundance. Hawaii Volcanoes National Park (HAVO) was surveyed in 2010, 2015/2016 and 2019/2020/2021. In 2020, Hawaii state public land was included in the suvery adjacent to the HAVO Kahuku tract, though Hawaii state data is not included in this dataset. Surveys were conducted in the National Park of American Samoa (NPSA) in 2011 and 2018, and in Haleakala National Park (HALE) in 2012 and 2017. In 2021, KALA was surveyed for the first time by the PACN. The entire survey areas were surveyed using point-transect distance sampling to calculate estimates of bird abundance and densities. Canopy cover and composition was collected at the same survey area. In addition to the permanent survey transects from past landbird surveys in the survey areas, randomly generated point-transects were also surveyed, providing a split panel sampling design. This dataset contains the results of the landbird point count survey for HAVO, NPSA, HALE, and KALA.
