The Science Issue and Relevance: Coastal wetlands are some of the most productive and valuable habitats in the world. Louisiana contains 40% of the United States’ coastal wetlands, which provide critical habitat for waterfowl and fisheries, as well as many other benefits, such as storm surge protection for coastal communities. In terms of ecosystem services, biological resource production, and infrastructure investments, the value of Louisiana’s coastal wetlands exceeds $100 billion. Thus, stakeholders are gravely concerned about sea-level rise which is causing coastal marsh habitat to convert to open water and resulting in the highest rates of wetland loss in the world, with nearly 1.2 million acres lost since...

Recently intensifying drought conditions have caused increased stress to non-native tamarisk vegetation across riparian areas of the San Carlos Apache Tribe (hereafter Tribe) and the Upper Gila River watershed in Arizona and New Mexico. This also increases wildfire risk in the area, making the removal of tamarisk vegetation a primary restoration and climate adaptation objective for the Tribe. The research from this project can improve the Tribe’s capacity to map tamarisk and other riparian vegetation, in addition to monitoring the relative condition and water stress of the vegetation in a timely manner. Specifically, the project will help identify where tamarisk is on the reservation and inform restoration actions...

Hawaiʻi and the United States Affiliated Pacific Islands face unique challenges in adapting to climate change due to geographic isolation, coastal hazards, close cultural and economic links natural resources, and underserved populations. To address these problems, the PI-CASC works to develop actionable research products through collaborative engagement with cultural and natural resource manager to ensure applicability of the research. In efforts to further support these co-production processes, the PI-CASC Management Climate Corps was developed to connect local natural resource managers, researchers, cultural practitioners, policy professionals, community leaders, and graduate students on Hawaiʻi Islands. The...

Moloka‘i has great wetland restoration potential in Hawaiʻi, but most remaining sites are highly degraded. The future of several endangered waterbirds and insects relies on restoring coastal wetland habitat that is resilient under sea-level rise and coastal flooding. Currently, managers lack background data on Molokaʻi to prioritize sites for restoration. In this project, Researchers will develop a comprehensive dataset and create a prioritization plan for coastal wetland restoration. The team will work closely with project partners and stakeholders to develop a well-vetted plan to support endangered species and meeting community needs. Existing maps and spatial data about the Molokaʻi landscape will be compiled...

Coastal flooding and erosion caused by storms and sea-level rise threaten infrastructure and public safety in Alaska Native communities. Though the problem is well known, there are few tools that can assess local vulnerability to coastal flood hazards. Even fewer tools can be customized with specific community information to support local adaptation planning. The main goal of this project is to use the Coastal Storm Modeling System (CoSMoS) platform to co-produce customized local flood hazard maps and online tools to support the development of culturally-appropriate and cost-efficient adaptation strategies in Alaska. The project team will work with federal, state, and local community representatives to understand...

Climatic warming has contributed to recent increases in severe wildfires across the Pacific Northwest (PNW). Following severe wildfire, a burned forest has an increased likelihood burning again within several decades, which can greatly alter vegetation recovery. These changes are of increasing concern to forest managers, conservationists, researchers, the public, and culture bearers. However, more information is needed to gauge how PNW forests respond to severe wildfire reburns under ongoing climate change. In this project, researchers and natural resource managers will jointly develop new applied science to anticipate and gauge the resilience of forests in the western Cascades of the PNW to climate change impacts....

The US Virgin Islands are vulnerable to sea level rise, intense storms, and unpredictable rainfall brought by climate change. These changes influence the health of freshwater streams (known as “ghuts”), sedimentation, erosion and water quality (“grit”), as well as aquatic communities and ecosystems (“gills”) that are unique to the islands and important for indigenous peoples’ heritage, local fishermen, tourism, and more. However, the US Virgin Islands have limited water resource data, and the data that exist are scattered across sources, creating an obstacle for adapting water management strategies. Preparing for and responding to climate change requires understanding the threats, priorities, solutions, and funding...

In 2020, Governor Edwards of Louisiana issued two executive orders: establishing the Climate Initiatives Task Force to develop the state’s first ever Climate Action Plan to reach net zero greenhouse gas emissions by 2050 and to enhance coastal resilience in the state. Louisiana’s coastal wetlands and natural lands are of vital importance not just for hurricane protection, health and wellbeing, and natural resources, but also for carbon sequestration (i.e. capturing and storage of carbon from the atmosphere). Enhancing natural carbon sinks (i.e. ecosystem that stores more carbon than it releases) to offset greenhouse gas emissions is a critical step for Louisiana to achieve its net zero goals. Coastal wetlands have...
