This report is a product of a one-week workshop on using Structured Decision Making to identify and prioritize conservation actions to address the threat of climate change on Hawaii‟s native forest bird community. Specifically, t his report addresses the issue of global warming ‟s likely role in increasing disease prevalence in upper elevation forests of Hawaii, negatively impacting native bird populations susceptible to the disease but currently disease - free because of the cooler temperatures at high elevations.

The Hawaiian Islands are home to some of the world’s most culturally valuable but imperiled forest birds, including brightly colored native honeycreepers, many of which are threatened or endangered. One of the major threats these birds face is avian malaria, which is spread by a species of introduced mosquito and can have death rates exceeding 90 percent. For decades, upper mountain forests have provided refuge for Hawaiian forest birds because mosquitoes (and thus the disease) could not survive the cooler temperatures. However, warming associated with climate change could change this. Scientists used climate data and an epidemiological model to evaluate the future impacts of avian malaria on Hawaiian forest birds...

The Pacific Islands Landscape Conservation Cooperative (PILCC) is one of 22 LCCs established by Secretarial Order No. 3289, which focus on on-the-ground strategic conservation efforts at the landscape level. LCCs are management-science partnerships that inform integrated resource-management actions addressing climate change and other stressors within and across landscapes.

In Hawaiʽi and elsewhere, research efforts have focused on two main approaches to determine the potential impacts of climate change on individual species: estimating species vulnerabilities and projecting responses of species to expected changes. We integrated these approaches by defining vulnerability as the inability of species to exhibit any of the responses necessary for persistence under climate change (i.e., tolerate projected changes, endure in microrefugia, or migrate to new climate-compatible areas, but excluding evolutionary adaptation). To operationalize this response-based definition of species vulnerability within a landscape-based analysis, we used current and future climate envelopes for each species...

This report summarizes the findings from a survey of natural resource managers in Hawaiʻi to establish a baseline assessment of concern about the influence of climate change on invasive species management, compare their access to and understanding of existing downscaled climate information for the state, and identify barriers to success in incorporating climate change into management practices. The survey (Appendix) was adapted from a similar survey instrument developed by the Northeast RISCC (see Beaury et al. 2020) and was exempt from Human Subjects Approval requirements by the East-West Center Institutional Review Board (IRB). The survey was distributed online through Hawaiʻi listservs and partners from December...
