Frequent, low-intensity wildfires were once widespread across the Southeast US, which led to a reduction in unchecked vegetation growth that provided fuel for high-intensity fires. Both intentional and unintentional fire suppression and land-use changes have reduced many of these wildfires and the fire-adapted habitats in the region over time. This loss of frequent low-intensity wildfires on the landscape also increases the severity of wildfires due to fuel buildup and the encroachment of woody species. The remaining habitats and their native species (many of which are of conservation concern) are now almost completely dependent on prescribed burns for their persistence and survival. Successful application of fire...

Climate change is causing an increase in the amount of forested area burned by wildfires in the western U.S. The warm, dry post-fire conditions of the region may limit tree regeneration in some areas, potentially causing a shift to non-forest vegetation. Managers are increasingly challenged by the combined impacts of greater wildfire activity, the significant uncertainty about whether forests will recover, and limited resources for reforestation efforts. Simultaneously, there has been an increased focus on post-fire reforestation efforts as tree planting has become a popular climate change mitigation strategy across the nation. Therefore, with increased interest and need, it is crucial to identify where varying...

Tribal resource managers in the southwest U.S. are facing a host of challenges related to environmental change, including increasing temperatures, longer periods of drought, and invasive species. These threats are exacerbating the existing challenges of managing complex ecosystems. In a rapidly changing environment, resource managers need powerful tools and the most complete information to make the most effective decisions possible. Traditional Ecological Knowledge has enabled Indigenous peoples to adaptively manage and thrive in diverse environments for thousands of years, yet it is generally underutilized and undervalued, particularly in the context of western scientific approaches. Traditional Ecological...

Natural and cultural resource managers across the country have begun to use a tool known as "scenario planning" to help prepare for climate change effects that may unfold in the future. In this process, scientific projections are used to identify different plausible, relevant, and divergent climate conditions for a particular area, and then through a participatory process, scientists and resource managers develop "scenarios" which describe the implications of these different conditions for resources and management. The North Central CASC has been working with the National Park Service (NPS) Climate Change Response Program (CCRP) to encourage and support national parks in incorporating climate science and scenario...

As a low-lying coastal nation, the Republic of the Marshall Islands is at the forefront of exposure to climate change impacts. The Republic of the Marshall Islands has a strong dependence on natural resources and biodiversity not only for food and income but also for culture and livelihood. However, these resources are threatened by rising sea levels and associated coastal hazards (storm surges, saltwater intrusion, erosion, etc.). High-quality data for atoll ‘ridge to reef’ (land and ocean) areas are needed to provide remote communities with the tools and strategies to make adaptation efforts before disasters occur. Although the Republic of the Marshall Islands’ National Strategic Plans recognize the need to...

Climate projections for the southern Great Plains, and elsewhere in the U.S., indicate that a hotter future with changes in precipitation amount and seasonality is to be expected. As plants become stressed from these changes, wildfire risk increases. One of the most valuable approaches to reducing the impacts of wildfires is fuel reduction through prescribed burns. Fuel reduction helps minimize the destruction of ecological communities, threats of future flooding, and extensive damages by lessening the intensity of future wildfires. Although safe burning practices can largely minimize the risks, prescribed burns may bring some degree of concern among practitioners. The real and perceived risks may include bodily...

As the National Climate Adaptation Science Center (CASC) develops a strategic effort around fire science, there is a critical need to develop a national-scale synthesis effort that identifies key regional CASC activities previously conducted, as well as major science gaps that may be addressed by a coordinated CASC network approach. The North Central CASC postdoctoral fellow will play a leadership role in the National CASC Climate Adaptation Postdoctoral (CAP) Fellows Future of Fire cohort to help identify the common efforts and leveraging points to shape the national-scale synthesis. Currently there is limited North Central CASC supported fire science available for the North Central region. To meet this need,...

Small lakes are important to local economies as sources of water supply and places of recreation. Commonly, lakes are considered more desirable for recreation if they are free of the thick weedy vegetation, often comprised of invasive species, that grows around the lake edge. This vegetation makes it difficult to launch boats and swim. In order to reduce this vegetation, a common technique in the Northeast and Midwest U.S. is a ‘winter drawdown’ . In a winter drawdown, the lake level is artificially lowered (via controls in a dam) during the winter to expose shoreline vegetation to freezing conditions, thereby killing them and preserving recreational value of the lake. However, this practice can impact both water...

Natural resource managers consistently identify invasive species as one of the biggest challenges for ecological adaptation to climate change. Yet climate change is often not considered during their management decision making. Given the many ways that invasive species and climate change will interact, such as changing fire regimes and facilitating the migration of high priority species, it is more critical than ever to integrate climate adaptation science and natural resource management. The coupling of climate adaptation and invasive species management remains limited by a lack of information, personnel, and funding. Those working on ecological adaptation to climate change have reported that information is not...

Invasive species establish outside of their native range, spread, and negatively impact ecosystems and economies. As temperatures rise, many invasive plants can spread into regions that were previously too cold for their survival. For example, kudzu, ‘the vine that ate the south’, was previously limited to mid-Atlantic states, but has recently started spreading in New Jersey and is expected to become invasive farther north. While scientists know of many of the invasive species expanding into the northeastern U.S., they do not know where those species are likely to become abundant and how they will impact vulnerable native ecosystems due to climate change. There are also currently no strategies to manage emerging...

Recreational angling in the U.S. represents a large group of people that catch and harvest fish for a variety of reasons, including for relaxation, adventure, social motivations, and consumption. Collectively, recreational anglers can exert pressures on both economies and fishery resources. Fish removals by anglers represent an important source of mortality data when trying to understand fish populations, and this information is even more important when the fishery is dominated by recreational and subsistence fishing. Currently, the magnitude of recreational angling is measured at local scales (for example, at a specific lake or stream) and the process to collect information from anglers varies widely by state...

Developing novel solutions to complex problems demands innovative approaches that are inclusive of diverse perspectives from both scientific experts and stakeholders. Across networked communities, like the South Central Climate Adaptation Science Center (CASC), it can sometimes be challenging to identify and build collaborations among researchers from different disciplines. Particularly at times like the present, during a global pandemic and recovery from its impact, a means to support a diverse, integrated and engaged network is essential for producing innovative outcomes for complex problems relevant to our changing climate. One method to foster more engaged networks is through the use of Exaptive’s Cognitive...

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...

American Samoa is vulnerable to sea-level rise in part due to the steep terrain of its islands. This terrain requires the majority of the islands’ villages and infrastructure to be located along thin strips of coastal land. The situation is worsened by the recently recognized rapid sinking of the islands, which was triggered by the 2009 Samoa earthquake and is predicted to last for decades. This subsidence is estimated to lead to roughly twice as much sea-level rise by 2060 as what is already predicted from climate change alone. As a result, the timeline of coastal impacts in American Samoa will be decades ahead of similar island communities in the Pacific. Despite this urgency, decision-makers in the region lack...

Freshwater is a critical driver for island ecosystems. In Hawaiʻi, though rainfall intensity has increased, total rainfall has been on the decline for the last two decades and, as a result, streamflow has also been reduced. The changes in dynamic patterns of streamflow could result in impacts to river, estuarine, and coastal habitats. In turn, these changes also affect the nine native Hawaiian aquatic species found in these habitats at different stages of their amphidromous life cycle (in which they migrate from fresh to salt water or vice versa). To examine how changes in streamflow regime have impacted habitat quality for native migratory aquatic species, an ongoing project has been examining statewide long-term...

Ecosystems such as coral reefs and mangroves provide an effective first line of defense against coastal hazards and represent a promising nature-based solution to adapt to sea-level rise. In many areas, coral reefs cause waves to break and lose energy, allowing for sediment to accumulate on the inshore portion of reef flats (i.e. the shallowest, flattest part of a reef) and mangroves to establish. Mangroves cause further attenuation (i.e. energy loss) waves and storm surge as water moves through roots and trunks of the trees. Together, these ecosystems provide valuable protection from coastal flooding, but is unclear how this protection may be affected by sea-level rise. An assessment of future sea-level rise vulnerability...

The fast pace of change in coastal zones, the trillions of dollars of investment in human communities in coastal areas, and the myriad of ecosystem services natural coastal environments provide makes managing climate-related risks along coasts a massive challenge for all of the U.S. coastal states and territories. Answering questions about both the costs and the benefits of alternative adaptation strategies in the near term is critical to taxpayers, decision-makers, and to the biodiversity of the planet. There is significant public and private interest in using ecosystem based adaptation approaches to conserve critical significant ecosystems in coastal watersheds, estuaries and intertidal zones and to protect man-made...
The ACF basin, from headwaters in north Georgia, to the Apalachicola Bay and estuary, is a focal geography in the Southeast and provides habitat to a diversity of species, including over 30 federally-listed T&E species, and over 30 species proposed for ESA listing, cross-taxa. Allocation of water for multiple uses in the ACF basin has been contentious for decades (e.g., FL v. GA, SCOTUS ruling issued 27 June 2018. A 4.5 day structured decision making (SDM) workshop with experienced SDM coaches is a necessary component to further ongoing adaptive management (AM) processes in the Apalachicola-Chattahoochee-Flint (ACF) River Basin.

The Hawai‘i Drought Knowledge Exchange project has been successfully piloting three sets of formal collaborative knowledge exchanges between researchers and managers to co-produce customized, site specific drought data products to meet the needs of their partners. Through these pilots, knowledge co-production has demonstrated how active collaboration between researchers and managers in the design and production of data products can lead to more useful and accessible applications for drought planning and management. Resource managers have strongly embraced the need for better and more timely information on climate change, variability and drought, as these stressors exert a large and costly impact on resources...

The South Central Climate Adaptation Science Center (CASC) has worked diligently to build new partnerships between scientists and resource managers to help address the science needs and questions of their stakeholders through actionable science. However, the growth of their stakeholder base and the loss of the Landscape Conservation Cooperatives has led to unmet demand for climate “extension services” from stakeholders. This project plans to establish a new scientist position at the South Central CASC focused on climate extension services and research coordination to help discover needed science solutions and to facilitate connections between the researcher and practitioner communities. The Climate Extension...
