Assessments that incorporate areas from land-to-ocean, or “ridge-to-reef", are critical to examine how land-use practices are altering stream discharge and nearshore marine health and productivity. Stream systems in both Alaska and Hawaiʻi are expected to experience changes in water quality associated with changing environmental conditions and increased human-use. Watershed systems...

The territory of American Samoa is highly vulnerable to the negative effects of climate change and there are many local agencies working towards adapting to this problem. These efforts often require organization, interpretation, or presentation of large amounts of data and information. However, those who directly need these data often do not have the time or experience to synthesize them...

For the past few years, “king tides,” or the highest tides of the year, have been occurring more frequently and significantly affecting coastal environments across Hawaiʻi. Now, disappearing beaches and waves crashing over roadways are seemingly the “new normal.” In response, the state of Hawaiʻi is implementing adaptation strategies to combat tidal flooding in coastal areas. While flood

The Hawaiian Islands have an extremely diverse number of plants and animals found nowhere else on Earth. Changes brought about by the arrival of humans and the introduction of non-native predators, weeds, and diseases has led to the extinction of hundreds of Hawaiian species – far more than any other U.S. state. To help the State of Hawaiʻi prevent additional species from becoming...

Aquatic ecosystems provide habitat and migration corridors to a myriad of species, including plants, fishes, amphibians, birds, mammals, and insects. These ecosystems typically contain relatively higher biodiversity than their terrestrial counterparts; yet, aquatic biodiversity loss in North America is occurring at a rate five times faster than in terrestrial ecosystems. One of the major...

Ongoing climate change is impacting areas of snow and ice in high latitudes and high elevation areas and is thus anticipated to change the frequency and magnitude of snow and ice related hazards. In Alaska, snow avalanches are the deadliest natural hazard, and they affect a large portion of the state, significantly impacting the natural landscape, the built environment, and public safety...

Indigenous peoples and nations are on the front lines of climate change impacts and are leading the way in innovative adaptation action, such as in the use of traditional burning. Traditional burning has been recognized as a robust adaptation strategy, increasing the resiliency of ecosystems and the local communities that depend on them for their economic and social well-being...

Pacific Island societies value, depend on, and actively manage terrestrial and marine ecosystems for the multiple benefits they provide, including those associated with plant and animal abundance, resilience to natural disasters, and the flow of water, soil, and nutrients. New ecosystem service models developed for Pacific Island landscapes now integrate land-to-sea connections, allowing...

As the climate continues to change, vulnerable wildlife species will need specific management strategies to help them adapt to these changes. One specific management strategy is based on the idea that some locations that species inhabit today will remain suitable over time and should be protected. The climate conditions at those locations will continue to be good enough for species to...

Hawaiʻi’s native forest birds are known worldwide for their diversity and beauty. Unfortunately, many species are heading towards extinction because of bird malaria spread by mosquitoes introduced over a century ago. Remaining populations of these highly threatened forest birds tend to be at high elevations near the tree line on mountains, where cooler temperatures limit mosquitoes and...

As pressures from climate change and other anthropogenic stressors, like invasive species, increase, new challenges arise for natural resource managers who are responsible for the health of public lands. One of the greatest challenges these managers face is that the traditional way of managing resources might not be as effective, or in some cases might be ineffective, in light of...

Ecosystems spanning the zones from “ridge-to-reef" and “icefield-to-ocean” are home to relatively high levels of biodiversity; serve as conduits of nutrients to sensitive coastal environments; and are culturally and economically important to local communities. These systems are smaller and have unique geological and streamflow properties compared to more typical river systems and...
