GROTON, CT (January 16, 2024) – Elementary, middle and high school students, teachers and the communities of 10 public schools in urban and suburban areas will comprise the new Long Island Sound Schools network, committing to the protection of local watersheds, the Sound and our one global ocean.

With funding by the U.S. Environmental Protection Agency’s Long Island Sound Study and facilitated by Connecticut Sea Grant and Mercy University, the program supports schools that implement a school or community-based project and create a plan to increase ocean literacy by engaging students, families and the public.

All the schools are located within the Long Island Sound watershed, from inland areas with waterways that flow into the estuary to shoreline communities. Program funding will provide stipends for lead teachers at each school and up to $5,000 per school to implement projects. The schools will also have access to a network of educators, connections with scientists, community organizations and stewardship sites, and possible travel funds for conference presentations.

“We have all been inspired by a teacher who has opened our minds to new possibilities and ambitions,” said Mark A. Tedesco, director of the EPA’s Long Island Sound Office. “The new Long Island Sound Schools network will support schools, teachers, and students in learning about Long Island Sound and actively engaging in its protection and conservation.”

The project began with a kick-off meeting of member schools on January 4. The schools will be implementing their projects starting on January 15 and concluding on August 15, as well as planning a student symposium and teacher retreat.

“The Long Island Sound Schools network builds on more than 20 years of success with the Long Island Sound Mentor Teacher program,” said Diana Payne, CT Sea Grant education coordinator. “It’s the next logical step—from fostering educators to incorporate Long Island Sound into their curriculum at the classroom level and expanding it to the school and community level.”

The program is modeled on the National Atmospheric and Oceanographic Administration’s (NOAA) Ocean Guardian Schools and the international Blue Schools network.

“This project is a wonderful opportunity for school communities to strengthen their connection to Long Island Sound and our global ocean, inspiring the next generation of ocean stewards,” said Meghan Marrero, professor of secondary science education and co-director of the Mercy University Center for STEM (Science, Technology, Engineering and Mathematics) Education. Payne and Marrero are co-leaders of the project.

The network schools in Connecticut are: Flanders Elementary, East Lyme; Mystic River Magnet; Torrington High; Trumbull High; Walter Fitzgerald Campus, Southport; and Waterford High. The network schools in New York are: Jefferson Elementary, New Rochelle; PS175X, Bronx; Smithtown High School West; and Trinity Elementary, New Rochelle.

In all, these Long Island Sound Futures Fund (Futures Fund) 2023 grants will support projects that improve water quality by preventing 2.7 million gallons of stormwater and 101,000 pounds of nitrogen pollution from flowing into Long Island Sound waters. The projects will also remove 120 tons of marine debris from the sound and support planning for restoration of 880 acres of coastal habitat and 102 miles of river corridor vital to fish and wildlife. And, the projects will reach 30,000 people through environmental education programs that increase awareness of how to improve the health and vitality of the Sound. Funding for the grant program comes from the EPA as part of the Long Island Sound Study (LISS), with additional support from FWS, NFWF and The Zoetis Foundation.

“Everyone that lives, works, and plays on the Sound deserves clean water and equitable access. By Investing in America, these grants, along with the huge investment in the Sound from the Bipartisan Infrastructure Law, put us on the right path,” said EPA New England Regional Administrator David W. Cash. “Because of these investments, EPA is making good on its promises to uplift communities, make them more resilient to climate change, and improve the health of the Sound as a whole.”

“EPA’s continued investments in locally based programs in and around Long Island Sound will tackle water quality improvements, reduce nitrogen pollution and restore coastal habitat,” said Regional Administrator Lisa F. Garcia of EPA Region 2. “EPA is proud to support these innovative and impactful projects that will improve the health and resilience of this vital estuary for generations to come and ensure that all communities have a voice and a role in the protection and restoration of the Sound.”

The LISS initiated the Futures Fund in 2005 through EPA’s Long Island Sound Office and NFWF. The grant program has a strong history of making environmental improvements by supporting people and communities who value the sound and take a direct role in its future. Since its inception, the Futures Fund has invested $56 million in 640 projects. The program has generated an additional $65 million in grantee matching funds towards these projects for a total conservation impact of $121 million. The projects have opened 121 river miles for fish passage, restored 842 acres of fish and wildlife habitat, treated 208 million gallons of stormwater pollution, and engaged 5 million people in protection and restoration of the Sound.

“This year’s grants provide support for grantees and their partners to implement projects that benefit community residents, farmers, fish, and wildlife” said Jeff Trandahl, executive director and CEO of NFWF. “The Long Island Sound’s watershed covers more than 16,000 square miles in six states and the funding today represents a commitment to foster the progress made over many decades towards a healthier, cleaner and more resilient watershed that will benefit wildlife and people for generations to come.”

“The projects funded today conserve and restore vital habitat for threatened and endangered wildlife like piping plovers and roseate terns, as well as include working directly with communities to create a future landscape more resilient to climate change,” said Wendi Weber, Northeast Regional Director for the U.S. Fish and Wildlife Service. “Removing dams and replacing culverts clears the way for migratory fish while reducing the risk of flooding. Living shorelines support fish and shellfish while buffering destructive storm surge. These grants support a brighter future for the people and wildlife of Long Island Sound.” 

“Since 2005, the State of Connecticut has been privileged to benefit from the groundbreaking and critical work of the National Fish and Wildlife Foundation through its Long Island Sound Futures Fund. Projects supported by the Futures Fund lead to real world advancement and improvements to the Long Island Sound, our most cherished natural resource,” said Emma Cimino, Connecticut Deputy Commissioner of Energy and Environmental Protection. “Today Connecticut joins in celebrating the award of over $7.5 million in 23 grants to 22 recipients in Connecticut, which leverage almost $4 million in additional local funding. These important and forward-thinking projects range from reducing nitrogen pollution and removing barriers to fish passage to improving the resilience of our coastal communities and providing pathways to conservation careers to young people from environmental justice communities. We are grateful to our federal partners for this impactful funding in Connecticut and those awarded in New York.” 


New York State Department of Environmental Conservation (DEC) Commissioner Basil Seggos said, “The Long Island Sound is an irreplaceable natural resource to New Yorkers and neighbors alike. Working hand-in-hand with stakeholders and key partners like the Long Island Sound Futures Fund, DEC is proud to see the extensive investments and efforts underway to restore and protect the Sound for future generations by improving water quality, conserving critical habitats, responsibly increasing recreational access, and empowering the public to safeguard this cherished natural resource. DEC congratulates and thanks grant awardees for their sustained dedication to the conservation of this vital ecosystem.”

Research along Connecticut coast uses “warming chambers” to heat plants to simulate the salt marsh environment in the coming decades

By Juanita Asapokhai

A coastal habitat teeming with wading birds, small fish, fiddler crabs, and more aquatic life. A “sink” for carbon absorbed from the atmosphere, lessening the effects of global warming. A shield for coastlines battered by harsh waters, and a buffer for coastal homes against storm damage.

These are some of the roles that salt marshes play within Long Island Sound’s ecosystem. Salt marshes, or tidal marshes, are defined in a CT Sea Grant manual as “the green belts and meadows we see between the upland and the tidal waters of the Sound’s bays, coves, and estuaries.” Globally, they are considered some of the most productive ecosystems on Earth, essential for the health of animals and protecting communities along the coast. But they are also under increasing threats from sea level rise and rising temperatures due to climate change. Motivated by these concerns, Dr. Sarah Crosby, a marine scientist and director of Director of Conservation and Policy at the Maritime Aquarium at Norwalk, is working with other scientists conducting research on how warming temperatures impact salt marsh grasses and what strategies can be developed to restore habitats to make them resilient to climate change. The research is being funded through the Long Island Sound Study Research Program.

For Crosby, who is working in a new position at the aquarium that has a focus on protecting Long Island Sound, resiliency is measured in terms of how successfully salt marshes in the region will withstand the increases and changes to its climate in the coming decades. It is demonstrated by maintaining, as she describes the salt marsh environment as: “their ability to continue to look like marshes and act like marshes under these changing conditions.”

To gain a better understanding of climate resiliency, the research will investigate how long-term healthy marshes along Connecticut’s shore respond to projected temperature hikes compared to marshes that have been restored in the recent past. Secondly, it will look into whether, as temperatures rise, southern-sourced Spartina alterniflora, with genetic features and evolutionary history shaped by a warmer, southern climate, fare better than locally-sourced Spartina alterniflora, with the genetic features and evolutionary history suited to the northern climate.

Spartina alterniflora, is the plant the research team, which besides Crosby includes Dr. LaTina Steele, an associate professor at Sacred Heart University, Dr. Randall Hughes, a professor at Northeastern University, and Nicole Spiller, the Director of Harbor Watch at Earthplace in Westport, CT is focused on. Also known as smooth cordgrass, the tall, slender grass inhabits the “low marsh,” the area of the salt marsh meadow closest to tidal waters where there is a daily occurrence of flooding. These grasses have a high tolerance for saltwater or brackish conditions. But in order to establish roots and survive in a wet and dry environment they are dependent on the buildup of sediment entering the marsh from daily tidal flow, as well as below ground biomass (from dead plants and organisms). The sediment and biomass must keep up with normal flooding and sea level rise. Any disruption to their habitat, such as increased sea level rise, can put their survival in jeopardy, and they will be forced to adapt, or die out.

Survival of the Fittest: Natural and Restored Marsh, Local-source and Southern-source Plants

To explore the potential effects of global warming on salt marsh plants, the research team selected eight sites across the Connecticut coast to observe and analyze Spartina alterniflora. Four of the sites are at long-established natural healthy marshes in the Sound: Oyster River and Gulf Pond located in Milford; the Bradford Preserve in East Haven; and Branford Harbor in Branford. The other four sites—the Great Meadows Marsh and Stratford Point in Stratford; the Housatonic River state boat launch in Milford; and the West River in West Haven—are restored marshes. Restored marshes are degraded marsh habitats that have been renewed by various managers and programs, including through the Long Island Sound Study’s Habitat Restoration Initiative.

During the spring of 2023, the team assembled several enclosures called warming chambers at each of the sites to simulate what the temperatures would be like for the plants in the coming decades. Using PVC pipes to create a cube-shaped base structure, the team enclosed plots (small areas of vegetated habitat being measured by the researchers) of Spartina alterniflora within these open-top chambers. The chambers were made by wrapping the PVC base in thick, greenhouse-grade plastic sheeting on each side of the cube. On the top sheet of plastic sheeting, a hole is punctured in the center to permit precipitation into the plot. The grasses at restored marsh sites, planted within the last 10 years, will be compared to their natural marsh counterparts. Prior research on Connecticut marshes done by Crosby and her team has highlighted differences between natural and restored marsh. The study demonstrated that below ground biomass assembling under the surface of salt marshes is holding up better in natural marshes than in restored marshes. That being said, other findings also demonstrate that restored marshes have higher levels of genetic diversity, an advantage for a species facing imminent changes to the environment it is accustomed to, like rising temperatures.

“You have a greater chance that one of those genotypes is well suited for the conditions that are about to happen,” said Crosby. Whether climate change warming will advantage one kind of marsh over another—and what methods or features can be adopted from one to use in another—will be explored using the data from the study.

Set aside from the other seven locations, at the Stratford Point site, 18 experimental plantings were set up within the sand where Spartina alterniflora is growing, adjacent to the salt marshes. The research team has set these potted plants to house local, Connecticut-sourced plants as well as southern-source plants, in a combination of mixed and separate (i.e., local or southern-source only) plots. The potted plants will be used to observe differences in locally sourced and southern-sourced plants’ response to the heating temperatures. The southern-sourced plants, taken from nurseries in South Carolina and Florida, will be removed at the end of the study, to avoid unintended consequences related to introducing nonnative species to the Stratford Point marsh habitat.

The data collected from these experiments will provide information for Crosby and the rest of the research team to assess how global warming influences the growth of salt marshes, as well as its impact on their ability to store carbon. They are also interested in observing how the warming they simulate might change the allocation of biomass in a saltmarsh’s grasses—either increasing its biomass, decreasing it, or having no effects and maintaining the same amount of biomass pre-predicted global warming temperatures. According to Crosby, such effects are indicated by changes in the roots and stems of Spartina alterniflora, like their height, density, and diameter. “Some of those things may change because of some of the differences we see with latitude in these species, and how the plants grow slightly differently down south versus up here,” she said.

Biomass is just one characteristic that impacts the resilience of salt marsh plants, their capacity to endure significant changes to their environment.

“Not drowning under sea level rise; continuing to provide the habitat that we want them to; continuing to protect our soil from erosion,” said Crosby, listing some of the key and of resilience. The survival of the marsh at large ultimately hinges on the survival of the plants, like Spartina alterniflora, that they are founded on.

Gaming the Gene Pool: Exploring genetic adaptation to rising temperatures

As the investigators continue their work in the field, which will be ongoing through the fall of 2024, another segment of the project is taking place at a greenhouse and laboratory at Northeastern University in Boston. Led by geneticist Randall Hughes, researchers are studying the DNA of southern and locally-sourced plants to understand the role that genetics may play in the changing climate landscape for Spartina alterniflora and the marshes they grow.


The scientists are using DNA sequencing technology on leaf-tissue samples to examine the characteristics of the naturally growing healthy marshes, restored marshes, and plants sourced from northern and southern greenhouses to gain a better understanding of how genetic makeup favors or hinders their ability to survive under the temperatures anticipated in coming decades. They also hope to identify opportunities for breeding between local and southern-source plants that may increase adaptive potential, or resilience, through the production of offspring with the most “resilient set of genetics.” A question remains, however, about whether differences in the timing of flowering will prevent such mixing.

Fortifying Our Marshes

As the team continues the data collection phase of the project, Crosby expresses her hopes for the application of the findings of the study to boost the resilience of the Sound’s salt marshes and “translate into different management of these ecosystems.”

Salt marshes have an important, multifaceted identity in the Long Island Sound as habitats, carbon reservoirs, and natural protectors of shorelines and residential areas from increasingly destructive coastal storms. Crosby’s research helps to support the larger goal of Long Island Sound Study restoration efforts.

The goal is that the findings will reveal “whether there’s something we can do, that’s as simple as buying our plants from a different place that might actually make a difference,” said Crosby. “There’s a lot of potential applicable pieces of information that we’re hoping will come out of this.”

Salt marsh meadows, also known as tidal marshes, grow from the long-term accumulation of plants such as Spartina alterniflora and sediment close to the shore. This growth is dependent on maintaining a balance between the periods of wetness and dryness caused by high tide and low tide that allows the plants and sediments to amass enough material to form the marsh. The ability of salt marsh to withstand fluctuations in sea level is essential to their survival. As global warming causes sea levels to rise, this balance is in jeopardy, and salt marsh plants like the Spartina alterniflora, also known as smooth cordgrass, will be forced to adapt, or die out. The worst outcomes of rising temperatures are still decades away, but, thanks to this research study funded by the Long Island Sound Study (see main story), researchers are seeking to get a better understanding of long-term impacts.

The role of the salt marsh in Long Island Sound’s ecosystem is multifaceted, with a long environmental history as a habitat for various species, and a historical and contemporary asset in the lives of Long Island Sound communities.

A visit to a beach or shoreline in the Sound with a thriving salt marsh will quickly showcase sprawling patches of Spartina alterniflora stretching up out of the water, not too far away from sediment and sand in the low marsh. A long, slender grass, Spartina alterniflora, also known as smooth cordgrass, is the foundation species of salt marshes in the Sound. The grass provides the base material that, over time, integrates biomass —plants and their petals, stems, roots, and other organic materials —with sediment to form the mass of salt marsh. In comparison with other “high” or upland marsh plants, Spartina alterniflora is particularly tolerant of the flooding brought by high tide, as the surface of the marsh and part of the plant is underwater. The optimal conditions for the growth of salt marsh occur within the intertidal zone. The intertidal zone refers to the cycle between wetness (as well as exposure to saltwater) and dryness directed by the tides that enables salt marsh to pace sea level rises by growing tall enough to avoid being submerged beneath the water too frequently.

The underground system of roots and material of plants like Spartina alterniflora enable salt marshes to function as effective nutrient sinks. Absorbed by the marsh plants through photosynthesis and by their roots, nutrients like carbon, nitrogen, and phosphorus accumulate in the below ground biomass for a long period of time, removing them from the Sound and the atmosphere. This is a particularly valuable feature of salt marshes in the case of carbon, a greenhouse gas.

Salt marshes play host to a variety of coastal birds. Ospreys and their nests are easily spotted close to these estuary habitats. Marshes are also a breeding ground for willets, a once-endangered species that, thanks to conservation efforts started in the 1970s, has since seen a significant boost in its numbers in the past few decades. The great blue heron, whose uniquely webbed feet allow them to navigate the muddy terrain of salt marshes with ease, lives on salt marshes throughout the year. Salt marshes support the broader food chain of the Long Island Sound by providing a habitat for fish like the mummichog and striped killifish that serve as food for species that dwell offshore. The juvenile offspring of horseshoe crabs and American eels reside within marshes until they have matured, at which point they move offshore. The biodiversity preserved and sustained by salt marshes makes them an essential fixture in the ecology of the Long Island Sound.

For communities of Long Island Sound, salt marshes have had several important roles throughout history. Precolonial indigenous cultures utilized salt marshes for fishing and farming for hay. The salt marshes present across the Sound today are a fraction of preexisting marshes, a large percentage of which have been eliminated for coastal development in the form of roads and residences. As homes continue to populate the coast and shorelines, the presence of salt marshes is needed now more than ever to act as a buffer for flooding and storm damage. When high-energy waves push water onto the shore, salt marsh vegetation such as Spartina alterniflora reduces the energy of the waves by providing friction, slowing the waves’ momentum and force on the shore and the homes beyond it. The below ground biomass of salt marshes helps to retain the position of the coastline and resist erosion due to storm waves.

The ecological conditions needed for this “vertical” growth are in jeopardy: as rising sea levels push salt marshes farther up the shore, where they run into developments on the Sound, like roads and train tracks. Further, as sea levels rise, the plant’s high tolerance for a wet environment has led to the creep of the species into higher marsh areas, where flooding is less frequent, and that serve as habitats for species, like the endangered salt marsh sparrow. Salt marsh conservation and restoration efforts are important steps to mitigating the projected effects of rising sea levels on the salt marsh ecosystem of the Long Island Sound and the various species that call marshes home.

The ability of the salt marsh meadows to withstand fluctuations in sea level is essential to their survival. The worst outcomes of rising temperatures are still decades away, but, research projects such as a 2022-fund project through the Long Island Sound Study Research Grant Program are providing decision-makers with information on how get a better understanding of long-term impacts and plan for the future.

Long Island Regional Planning Council offers ‘Garden Rewards’ grant program for homeowners to reduce runoff and nitrogen pollution

In early May 2023, the Long Island Regional Planning Council announced the Garden Rewards Program for Long Island homeowners (see news release below). The Long Island Sound Study provided additional funding to this program for eligible residents on the North Shore (residents who live in the Long Island Sound watershed). This additional money helps to increase the capacity of the program.

The program is off to a good start. See the update at the bottom of the page.

Up to $500 available to individual homeowners to install rain barrels, rain gardens and native plantings

Syosset, NY – [May 1, 2023] – Long Island homeowners looking to play a role in reducing stormwater runoff, which is one of the leading causes of nitrogen pollution in our waterways, will soon be eligible for grants to help cover the cost and maintenance of runoff mitigation projects on their property.

Long Island Garden Rewards Program logo

The Long Island Regional Planning Council (LIRPC), in partnership with the New York State Department of Environmental Conservation (DEC) and NEIWPCC, is introducing the Long Island Garden Rewards Program which will provide up to $500 to offset the expense of installing green infrastructure on their properties including rain barrels, native plantings, and rain gardens.

“The quality of our surface waters, and of our drinking water beneath us, is threatened by excess nitrogen pollution created by stormwater runoff,” stated John Cameron, LIRPC Chairman. “While municipalities on every level are addressing stormwater runoff and nitrogen pollution, the Long Island Regional Planning Council saw the need to encourage homeowners to become a part of the solution in their own small but significant way.”  

Excess nitrogen causes toxic algal blooms that lead to low oxygen conditions, fish kills, harmful algal blooms, degraded wetlands and marine habitats. Nitrogen also contaminates the groundwater, which is the sole source of Long Island’s drinking water supply.

DEC Commissioner Basil Seggos said, “DEC is committed to protecting Long Island water quality in partnership with the Long Island Regional Planning Council, NEIWPCC, and Nassau and Suffolk counties. Reducing nitrogen pollution is critical to improving water quality, protecting groundwater, and strengthening the long-term health of marine life. DEC encourages homeowners to take part in the Long Island Garden Rewards Program and talk to neighbors about how green infrastructure can reduce runoff and protect the environment.”

“It has been great working with LIRPC and NYSDEC to build out this program, and I’m excited for this launch!” said Courtney Botelho, NEIWPCC Environmental Analyst. “The program offers Long Island residents a hands-on opportunity to meaningfully contribute to local water quality improvements right from their yards.”

Under the Long Island Garden Rewards Program, homeowners can receive a maximum of $500 to help cover the cost of their projects.

Rain Barrels: Rain Barrels reduce stormwater runoff by collecting and storing rainwater for homeowners to later use in their yards and gardens, also helping conserve water consumption. Barrels must be a minimum of 50 gallons and are required to have mosquito netting or screening. Reimbursement of up to $125 for each barrel will be provided for purchase, up to $500 maximum.

Native Plantings: Native plants are heartier and more resilient to local climate conditions. Native plant plantings can reduce water usage, reduce fertilizer and pesticide usage, and promote biodiversity. These native plants help promote a healthy ecosystem and are more resistant to local weather.

Rain Gardens: Rain gardens collect rainwater from roofs, driveways and other surfaces and allow that rain to soak into the ground. Rain gardens can filter stormwater before it reaches local waterways, mitigate flooding caused by pavement and enhance your yard with low maintenance landscaping. To be eligible, a rain garden must be a minimum of 20 square feet, use native plants and be maintained for at least three years.

About Long Island Regional Planning Council

The Long Island Regional Planning Council comprises public and private sector leaders who are experienced and knowledgeable in business, environment, transportation, and planning. Its mission is to educate Long Island officials, stakeholders and residents on key issues affecting the quality of life in the region, and to propose immediate and long-term strategies and solutions.

Update (Oct. 4, 2023)—The Long Island Garden Reward Program is off to a good start. As of Oct. 2, a total of 195 Long Island residents, including 80 residents in the Long Island Sound watershed, received up to $500 this summer and fall to offset the expense of installing native plants, rain gardens, and rain barrels in their yards. The commitment from these homeowners benefits all Long Islanders by helping to reduce stormwater runoff, which is one of the leading causes of nitrogen pollution in local waterways.  The program is expected to continue next year.
