Surveys for immature life stages of the Samoan swallowtail butterfly (Papilio godeffroyi) were conducted on 117 individually marked host trees (Micromelum minutum) in eight forest stands on Tutuila Island, American Samoa, at approximately monthly intervals during 2013-2014. The eight stands were mostly in or adjacent to the National Park of American Samoa (NPSA), but one stand was sampled near the western tip of Tutuila, outside NPSA. An additional 74 host trees were assessed for phenological status in the eight stands but were not surveyed for Papilio. This dataset contains information on the area and number of host trees surveyed for Papilio or phenology in each stand.

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...

These data were compiled for research pertaining to the effects of stand density treatments on growth rates in semi-arid, ponderosa pine forests. Also, these data examined how the planned restoration treatments in the Four Forests Restoration Initiative (4FRI), the largest forest restoration project being implemented in the United States, would alter landscape-scale patterns of forest growth and drought vulnerability throughout the 21st century. Using drought-growth relationships developed within the landscape, we considered a suite of climate and thinning scenarios and estimated both average forest growth and the proportion of years with extremely low growth as a measure of vulnerability to long-term decline. The...

The Hawaiian hoary bat (Lasiurus cinereus semotus), a federally and state listed endangered subspecies, is the only extant native terrestrial mammal in the Hawaiian archipelago. It is an insectivorous, solitary and foliage-roosting species that generally roosts alone or in mother-pup family groups. A total of 58 bats (17 female; 41 male; 56 adult; 2 juvenile) were captured at multiple locations on the east side of Hawaii Island from May 2018 through September 2019. Radio transmitters were affixed to 56 bats including two individuals that were recaptured and radio-tagged twice. When possible, radio telemetry was used to locate bats in trees and forest stands used for day-roosting. A total of 23 trees were identified...
