Hawaii Army National Guard (HIARNG) Hawaiian Hoary Bat Acoustic Long Term Data 2012-2018

Acoustic sampling for occurrence of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus) was conducted at 18 “long-term” acoustic monitoring stations on 12 Hawaii Army National Guard (HIARNG) installations across the islands of Hawaii, Maui, Molokai, Oahu, and Kauai between 2012 and 2018. Bats were confirmed as present at 10 of these installations: Keala

Hawaii Island forest bird response to simulated nest predator 2015-2016

Hawaii forest birds nesting in Hakalau Forest National Wildlife Refuge were exposed to models of predators near their nests to measure behavioral responses. Responses to potential nest predators included vocalization rate, movement behavior, and nestling feeding. Predators were inert stick, introduced but abundant predator, a rat, and a novel predator, a snake, that does not occur o

Hawaii Island, modelled density of malaria-resistant and -susceptible Iiwi following release of malaria-resistant birds under three climate change projections, 2030-2100

This data set provides the simulated results of releasing malaria-resistant Iiwi into existing populations of wild birds on the Island of Hawaii. Resistant birds are released into mid- and high-elevation forests at different densities at 10-year intervals from 2030 to 2070. Populations of both malaria-resistant and susceptible Iiwi are then predicted at 10-year intervals from release until...

Oahu Island Hawaiian stilt GPS satellite tracking data, 2017-2018

Lotek Pinpoint Global Positioning System (GPS) Argos Satellite tracking tags were placed on 4 Hawaiian Stilts on Oahu island in 2017. The birds were tracked from 19 July 2017 to 12 February 2018, with locations taken daily every 1.5 hours from 0400to 2000 Hawaii Standard Time. For each location, a description of the general habitat as 1) Wetland, 2) undeveloped field, 3) sport f

Modeled potential presence of Ceratocystis luhuohia across Hawaiian Islands

Hawaiʹi’s most widespread native tree, ʹōhiʹa lehua (Metrosideros polymorpha), has been dying across large areas of Hawaiʹi Island mainly due to two fungal pathogens (Ceratocystis lukuohia and Ceratocystis huliohia) that cause a disease collectively known as Rapid ʹŌhiʹa Death (ROD). Here we examine patterns of positive detections of
