This project will develop first-ever maps of ecosystem types (landcover) for the Mariana Islands. Native and alien plant communities will be classified and delineated using high-resolution satellite imagery, data from ground surveys, and new surveys where needed to ground-truth the classification. This effort will inform prioritization of conservation actions and will allow projection of future vegetation changes with climate change

Past analysis has shown that temperature-dependent avian malaria is likely to reduce overall available Hawaiian forest bird habitat with temperature increases. We used a comprehensive database of forest bird sightings (over 42,000 points), the most up to date regional climate projections and state-of-the-art ensemble species distribution models to project shifts in distribution of all Hawaiian forest bird species due to climate change. Our results show that all forest bird species are expected to suffer large range losses by end of this century with single island endemics at a greater risk than more widespread species. Because most species require structurally complex forest habitat that may take decades to develop,...

Hawaiʻi is considered a worldwide biodiversity hotspot, with nearly 90 percent of its native plants found nowhere else in the world. However, about half of these native plants are imperiled by threats including human development, non-native species, and climate change. Through this project, scientists modeled the relative vulnerability of over 1,000 native plant species to the effects of climate change. A panel of experts in Hawaiian plant species assisted with the development of the model and verified its results. From the model, researchers were able to develop a vulnerability score for each plant species and identify categories of species with high, medium, and low vulnerability to climate change. This information...

One of the impacts of global climate change for the Hawaiian Islands is a projected increase in sea level of about one meter by the year 2100. This change will impact both biological and cultural resources located along the coastline. Few intact native coastal and lowland plant communities remain in Hawai’i. Many of those that remain contain listed endangered species and provide important habitat for other species such as seabirds, shorebirds, and native invertebrates. Where upslope habitats are available, some coastal plant communities may be able to migrate in response to sea level rise. However, in sites that have no upslope opportunities due to habitat modification by human development, the species and communities...
