Upcoming Webinars

09/08/2022 - 3:00pm to 4:00pm - Speaker(s): Pua'ala Pascua, Eleanor Sterling, and Rachel Dacks

Ecosystem service assessments are a top priority at many reserves in the National Estuarine Research Reserve System. However, within ecosystem services research, there is a critical gap surrounding the equitable representation of cultural ecosystem services (CES) — one of four main categories of ecosystem services. The inclusion of CES in natural resource planning is critical, as they encompass the diverse suite of interactions between humans and the environment that maintain place-based values, worldviews, cultural identity, and well-being.

Through a catalyst grant, a project team worked with two sites in the Pacific – He‘eia Reserve in Hawai‘i and Kachemak Bay Reserve in Alaska – to advance the equitable representation of CES in estuary stewardship. In this webinar, three project team members will discuss strategies implemented to deepen and expand the meaningful inclusion of CES in estuary stewardship and management. They will share lessons learned in identifying and implementing CES in reserve management and in co-designing deliverables and approaches for end user needs.

05/25/2021 - 3:00pm to 4:00pm - Speaker(s): Dan Rogers, Tonna-Marie Surgeon Rogers, and Paraskevi (Vivian) Mara

Excess nitrogen in coastal waters can lead to a variety of problems, including algal blooms, fish kills and beach closures, but there aren’t easy solutions. In Massachusetts, towns along Cape Cod have been exploring the use of non-traditional methods for meeting nitrogen reduction requirements, such as establishing shellfish aquaculture operations in coastal waters. This webinar featured a recently completed research project that addressed critical information gaps identified by water quality managers and regulators - specifically the needs to quantify the nitrogen removal rates of commercial shellfish growing practices, and to identify best practices for siting and maintaining aquaculture operations that maximize benefits for water quality.  

In partnership with the Town of Falmouth, the project team studied the microbial communities and measured nitrogen fluxes in the sediment below three popular systems for growing oysters. They found that all three growing systems increased rates of denitrification and enhanced nitrogen removal, but aquaculture projects need to be carefully sited for best results. To share their findings, the team developed a best practices guide for growers, an eight-part video series to help inform local and regional planning boards, and signs and a demonstration site to help school groups and reserve visitors learn more about shellfish aquaculture.

04/27/2021 - 2:00pm to 3:00pm - Speaker(s): Coowe Walker and Mark Rains

In Alaska’s Kenai Lowlands, groundwater is key to healthy watersheds and resilient salmon, farms, and communities. Groundwater discharge provides important ecological services to salmon streams by moderating temperatures, maintaining stream flows, delivering nutrients, and creating overwintering habitat. To better understand the availability of groundwater and how human activities impact this resource, researchers at the Kachemak Bay Reserve and the University of South Florida built a predictive model that shows the depth and extent of aquifers and predicts groundwater discharge and recharge.

In this webinar, project team members shared how their findings generated new insight into groundwater in southern Kenai Lowland watersheds, and how their model revealed the precariousness of groundwater resources and the potential for competition among users. They discussed how engagement with stakeholders has increased awareness of the need to actively manage this limited resource, and how the community has begun to shift policies and practices to build toward more resilient groundwater resources.

03/31/2021 - 3:00pm to 4:00pm - Speaker(s): Y. Peter Sheng and Sarah Fernald

As coastal communities strive to safeguard themselves from increasing storm risks, they are looking for ways to maximize the protective powers of their natural features such as coastal wetlands. This project closely examined one marsh complex that lies adjacent to Piermont Village along the Hudson River Estuary in New York. Village residents wanted to better understand how Piermont Marsh would buffer their village from storm-induced flooding and waves, and whether a proposed plan to restore native cattails within a small area of the Phragmites-dominated marsh would lessen its buffering capacity.

In this webinar, two members of the project team explained how the team used state of the art modeling methods to simulate marsh vegetation and storm impacts produced by a series of past and future storm scenarios. By looking back at Superstorm Sandy in 2012 and projecting how much worse the damage could have been without the marsh, the research team was able to put a dollar value on Piermont Marsh’s buffering services. They shared key takeaways from the research and explained how the findings are informing planning for the marsh and shoreline infrastructure.

02/23/2021 - 3:00pm to 4:00pm - Speaker(s): Richard Lathrop, Lisa Auermuller, Kaitlin Gannon, and Dina Fonseca

As climate change and sea level rise alter salt marsh habitats, a less understood impact - with implications for human health - is how changes in marsh habitat affect the production and location of nuisance mosquito populations. Understanding how coastal ecosystems are being impacted by climate change, and how nuisance mosquito populations are changing, is critical to ensuring coastal managers make the most informed decisions going forward.  

In this webinar, project team members described how data-collection, mapping, and modeling efforts have resulted in increased clarity about marsh habitat change to inform mosquito control and coastal restoration efforts in New Jersey. Future modeling and marsh‐upland edge mapping suggest that the marsh‐upland is and will be a hotspot for change, and field sampling confirmed that these “new” habitats can serve as breeding areas for mosquitoes. The team also developed environmental DNA (eDNA) assays for the most common salt marsh mosquitoes in the Middle Atlantic United States. Working closely with mosquito control agency personnel, the team has made major advancements in mosquito surveillance through the deployment of drone-based sampling of breeding pools paired with the eDNA analyses. The team also developed outreach materials to inform the public about health risks posed by mosquitoes, including how climate change might exacerbate those risks, and a module for middle/high school educators.

Collaborative science involves working closely with partners at every stage - from conceptualizing a new project, to conducting the research, to refining tools to best meet a management need. In May 2020, hoping to start a dialogue around virtual engagement for collaborative science, we held a webinar to reflect on the ways in which collaborative science practices have been impacted by COVID-19.

As January 2021 drew to a close, most of us were thinking about the myriad stressors that continuec to pose challenges to virtual collaboration, life, and everything in between. In this webinar, we discussed what kind of tracking and evaluation we’d done to date, and explored how we continue to do our work in the midst of distractions. The discussion built on panelists’ comments to tease out the implications of these new practices for future collaborative science work, and how these lessons can be applied to coastal science within and beyond the NERRS.

One of the most challenging parts of advancing climate adaptation is defining what success looks like and tracking progress toward those goals. Over the past six years, a group of National Estuarine Research Reserves has been finding creative ways to tackle this problem in their own communities through the Successful Adaptation Indicators and Metrics project. In 2020, the team launched a new web-based toolkit - Resilience Metrics - which shares a suite of lessons learned, tools and tactics to help communities identify locally relevant climate adaptation metrics.

In this webinar, two members of the project team shared their experiences and lessons learned with defining climate adaptation success - conceptually and in practice. They introduced the resources available on the Resilience Metrics toolkit and explained how the case studies, job aids and facilitation tools can be used by coastal managers and adaptation professionals everywhere to facilitate conversations and planning around successful adaptation

North Carolina’s shellfish aquaculture industry has been small but stable for over 30 years. The southern portion of the North Carolina coast has consistently provided more than 50 percent of the wild harvest in the state, which has been  driving interest in creating new oyster farms throughout the region. Simultaneously, increased interest in shellfish aquaculture has placed pressure on resource managers making siting decisions. New farms provide an opportunity to assess conditions after farm installation, making North Carolina estuaries an ideal place to explore the ecosystem services of shellfish farming. This project aimed to link small-scale changes around oyster farms with larger-scale ecosystem-level alterations, and provide local assessment of ecosystem services to be considered by decision-makers.

In this webinar, project team members described how two years of intensive sampling in and adjacent to oyster farms and ongoing collaboration with oyster farms and the policy community has resulted in the production of visualization tools and models that will allow resource managers, shellfish growers, and other end users to make better decisions when determining the locations and scales of shellfish farming operations. The team found that environmental impacts of these farms were minimal, but that policy decisions were more complex. This finding led to an additional project examining the extent of shellfish aquaculture within the nationwide Reserve system.

Hundreds of dams built on tributaries of the Hudson River estuary have outlived their usefulness. Removing these relic dams is a priority for the state of New York in order to improve aquatic habitat connectivity, restore fish spawning grounds, and reduce the risk of dam failure. To better understand how sediment released by dam removals in the Lower Hudson River watershed will affect the 240 km-long estuary, including the potential for dam-derived sediments to help build tidal wetland resilience in the face of sea level rise, the Dams and Sediment in the Hudson (DaSH) project brought together a collaborative team of scientists and stakeholders to research key questions and provide practical tools to regulators and practitioners. 

In this webinar, project team members shared how their multidisciplinary approach - which combined field observations with analyses of sediment transport, and integrated feedback from a broad coalition of stakeholders - allowed them to answer questions about how dam removal will impact conditions in the estuary. They presented key findings about marsh accretion and introduced a tool they developed that allows engineers and regulators to estimate the amount of sediment stored behind a dam and assess preliminary impacts of sediment release following dam removal. To learn about their findings and tools visit the DasH project page.
