Pearl Harbor National Memorial, O‘ahu Hawaiian Hoary bat acoustic activity and tree metric data, 2024
We examined acoustic activity of the endangered Hawaiian hoary bat ('ōpe'ape'a; Lasiurus semotus), as well as surveyed potential roost trees at Pearl Harbor National Memorial (PERL) located on Ford Island, O‘ahu, Hawaii. The study area was located at the Ford Island Chief Petty Officer's (CPO) Bungalows Neighborhood, which covers approximately 4 acres and includes five historic CPO bungalows. Hawaiian hoary bat echolocation vocalizations were recorded at four acoustic stations (PERL1 - PERL4) located between 20 and 25 m above sea level, that operated nightly from June 2024 through December 2024. We collected 357,802 acoustic files over 653 station nights. Bat acoustic activity was detected in all months monitored except for June. Additionally, we collected tree metrics including tree species, height, diameter at breast height (DBH), canopy cover, at 12 trees within the study area.
This data release consists of five tabular data sets including bat acoustic activity at each site, and tree metrics data.
