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 throughout the Hawaiian Islands are currently experiencing impacts from climate change that affect groundwater recharge and surface runoff, erosion, and total streamflow, and cause degradation of nearshore marine habitats. This study can provide useful insight for both Alaska and Hawaiʻi by providing resources on how patterns in stream...

Coral reefs are declining worldwide due to a combination of stressors, but climate induced ocean warming is the biggest threat. Warming oceans lead to ‘coral bleaching’ and frequent death, compromising the structure and function of reefs. The increasing frequency and severity of bleaching means that human intervention is needed to support the adaptive capacity of reefs. Most proposed interventions involve the movement of corals, but the outcomes of these strategies are almost completely unknown. To bridge this knowledge gap, this project aims to assess how restoration to enhance resilience within coral reefs can effectively reduce climate change threats while also gaining a better understanding of socio-cultural...

In this project, we assessed the potential for twelve coastal wetland sites on the island of Molokaʻi, Hawaiʻi, to provide socio-cultural resources and habitat for flora and fauna following restoration. In April 2022, a rapid field assessment of hydrology, soils, and vegetation was carried out at each of the wetland sites. The data provided here were collected in order to inform a prioritization protocol for ranking wetlands on Molokaʻi for restoration. Soil samples were collected at each of the sites at three different depth ranges (0-2, 24-26, and 48-50 cm). Samples from 0-2 cm and 24-26 cm were analyzed for % organic carbon and soil texture. These two measures provide a basic understanding of the status of coastal...
Hawaiian coastal wetlands provide important habitat for federally endangered waterbirds and socio-cultural resources for Native Hawaiians. Currently, Hawaiian coastal wetlands are degraded by development, sedimentation, and invasive species and, thus, require restoration. Little is known about their original structure and function due to the large-scale alteration of the lowland landscape since European contact. Here, we used 1) rapid field assessments of hydrology, vegetation, soils, and birds, 2) a comprehensive analysis of endangered bird habitat value, 3) site spatial characteristics, 4) sea-level rise projections for 2050 and 2100 and wetland migration potential, and 5) preferences of the Native Hawaiian community...

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 malaria development. With rising temperatures in those upslope areas due to climate change, mosquitoes and disease are starting to be found at higher elevations. In addition to warming temperatures, increasingly dry conditions change stream flow allowing for the creation of pools that provide additional larval mosquito habitat in...
