Pacific Island Network Molokai Landbird Surveys Dataset 2021

Published by National Park Service | Department of the Interior | Metadata Last Checked: June 25, 2025 | Last Modified: 2023-08-15
In 2021, on the island of Molokai, reserves managed by The Nature Conservancy and the Hawaii Department of Land and Natural Resources; as well as Kalaupapa National Park were surveyed for landbirds and landbird habitat in order to provide information for monitoring long-term trends in forest bird distribution, density, and abundance. Based on the point-transect distance sampling history on Molakai, a 3,527-ha core area was defined to assess long-term population trends since 1979, when the first surveys were conducted. Areas of Kalaupapa National Park were excluded from the core area because of an intermittent survey schedule. However, this dataset provides all of the 2021 survey data including areas inside and outside the core area, which is denoted by “Core_Area”. A summary of the 2021 survey results for the core area and for Kalauapapa National Park will be provided in separate products, such as an NPS National Resource Report and a relevant scientific journal. The 2021 survey effort is expected to be repeated in collaboration with PACN, The Nature Conservancy, the Maui Forest Bird Recovery Project, and the Hawaii Department of Land and Natural Resources every 5-6 years.
