Hawaiian hoary bat roost stand metrics, Hawaii Island 2018-2019
Hawaiian hoary bats (Lasiurus cinereus semotus) were captured at multiple locations on the east side of Hawaii Island from May 2018 through September 2019. Radio transmitters were affixed to captured bats and, when possible, radio-telemetry was used to locate bats in forest stands used for day-roosting. A roost’s forest stand was defined as a 50-m radius circle around a roost location, which was established in two ways: 1) a bat was tracked to a specific roost tree location using radio telemetry and/or visual confirmation of a bat’s presence was made, or 2) when a specific roost tree could not be identified, the multiple points and compass bearings recorded during radio-tracking were analyzed with LOAS software (version 4.0.3.8, Ecological Software Solutions LLC, Urnäsh, Switzerland) to estimate the X,Y coordinates of the bat's roosting location.
A total of 45 bat day-roosts were identified to forest stand and used by 33 bats (23 male; 10 female; 32 adult; 1 juvenile). During the period of monitoring of telemetered bats (less than one month), eight bats used multiple forest stands. Twenty-six forest stands used for bat day roosts were located in Hawaii State administered lands, with the rest on private property. Forest stands ranged in elevation from 13 to 1654 m asl. Dominant canopy trees in forest stands used by roosting bats were primarily comprised of non-native plantation or invasive species, although native Metrosideros polymorpha was the dominant or co-dominant canopy tree in nine forest stands. Mean forest stand canopy height ranged from 11 to 44 m (mean = 23 m).
