The USFWS (Service) supports the State of Hawai‘i in conserving endangered Hawaiian forest birds, through technical assistance and management support. Two critically endangered forest birds endemic to KauaŹ»i, the ‘Akikiki and the ‘Akeke‘e, are facing imminent extinction (potentially within three years) if immediate action is not taken. The most important threat is introduced mosquito-borne diseases, amplified by climate change due to the movement of disease-carrying mosquitoes into high-elevation refugia as warming progresses. This threat cannot yet be addressed at a landscape level on Kaua‘i. A Service-funded structured decision-making process identified translocation as the next appropriate option for their conservation....

The endemic subspecies of the Pacific sheath-tailed bat (payeyi; Emballonura semicaudata rotensis), and the Mariana swiftlet (chachaguak; Aerodramus bartschi) once inhabited many of the islands that comprise the Mariana archipelago (Lemke 1986, Flannery 1995, Ellison et al. 2003, Cruz et al. 2008). Both are insectivorous species that roost or nest almost exclusively in natural limestone caves (Pratt et al. 1987). Population threats to these two species primarily include habitat loss from past clearing of native forest for agriculture, with subsequent replacement by invasive vegetation (particularly Lantana camara), habitat degradation from feral goat browsing, persistent disturbance of nests and roosts, pesticide...

This project will compare relative Culex abundances, and the prevalence of Plasmodium relictum, in mosquitoes and birds at the upper and lower bounds of a key portion of the kiwikiu and ‘akohekohe ranges. This information will be used to inform the design and implementation of landscape-level mosquito control technique. In addition, it will provide critical information on habitat suitability and imminent disease risk for the two critically endangered Maui forest birds. This project will provide baseline comparative information on mosquito distribution and avian malaria infection prevalence in mosquitoes and birds within a key portion of kiwikiu and ‘akohekohe range. The project products will be made available to...

The objective of the project is to provide the Hawaii Division of Aquatic Resources (DAR) with easy-to-use geospatial tools necessary to running a science-based participatory 30x30 planning process, and the technical support and iterative evaluation activities required to ensure the tools are implemented effectively. The work will enable stakeholders to effectively engage with relevant spatial data and information as they identify areas for consideration in the 30x30 planning. The project will accomplish the proposed objectives by: 1) providing spatial data layers in the interactive SeaSketch platform; 2) working closely with DAR staff on facilitation technique; 3) reproducing existing analytical tools developed...

The Hakalau Forest National Wildlife Refuge (Refuge), on the windward slopes of Mauna Kea, Hawai’i, is an important habitat for Hawaiian forest birds and plants, several of which are listed as endangered. Surrounding lands are managed by a variety of entities for conservation and other purposes. This landscape is experiencing environmental change, and is projected to experience altered temperatures and rainfall patterns in coming decades. In turn, these changes will likely alter the distributions of invasive weeds and mosquitoes, and reduce or eliminate populations of sensitive native species. The Refuge has conducted extensive forest restoration, and adjacent landowners are also conducting restoration activities....
