Protecting Wetlands and Coastal Dunes in the USA: Programs and Solutions. Wetlands and coastal dunes protect communities and ecosystems. Learn why they matter and discover five organizations working to preserve them across the U.S. Why wetlands and coastal dunes matter Wetlands and coastal dunes are among the most valuable ecosystems in the United States, yet they are also some of the most threatened. Wetlands filter water, store carbon, and provide habitat for countless species. Coastal dunes act as natural barriers against storms and erosion, shielding communities from flooding and property damage. Together, these ecosystems are critical to both ecological health and human safety. According to the U.S. Fish and Wildlife Service, the lower 48 states lost more than 290,000 acres of wetlands between 2009 and 2019, continuing a centuries-long trend of decline. Coastal dunes face similar threats from development, climate change, and rising sea levels. Protecting these ecosystems is not only about conserving biodiversity — it is about ensuring the resilience of communities in the face of environmental change. The ecological importance Wetlands Wetlands provide vital services that sustain both wildlife and humans. They filter pollutants from water, recharge groundwater supplies, and store carbon, making them essential in the fight against climate change. Wetlands also serve as breeding grounds and stopover points for migratory birds, and habitat for fish, amphibians, and mammals. Coastal dunes Coastal dunes protect shorelines by absorbing the energy of waves and storm surges. They prevent erosion, protect infrastructure, and provide habitat for rare plants and animals adapted to sandy environments. Healthy dune systems also support tourism and recreation industries by maintaining beautiful, resilient beaches. Threats to wetlands and dunes Urban and industrial development Expanding cities, highways, and industrial projects often come at the expense of wetlands and dunes. Once destroyed, these ecosystems take decades — if not centuries — to recover. Agriculture Agricultural expansion and drainage have historically been the largest cause of wetland loss in the U.S. Runoff from farms also introduces fertilizers and pesticides, degrading water quality. Climate change Rising sea levels and more frequent storms threaten coastal dunes and wetlands. Saltwater intrusion alters ecosystems, while powerful storms physically erode protective dunes. Pollution Wetlands are natural filters, but they cannot withstand endless amounts of pollutants. Industrial discharges, sewage, and plastic pollution disrupt fragile ecological balances. Invasive species Non-native plants and animals crowd out native species, weakening ecosystems and reducing biodiversity. Why protection matters for people Flood control Wetlands and dunes act as natural defenses. A single acre of wetlands can store up to 1.5 million gallons of floodwater, while dunes buffer communities from destructive storm surges. Climate resilience By storing carbon and absorbing storm energy, these ecosystems are frontline defenses against climate change. Economic benefits Healthy wetlands support fisheries, hunting, birdwatching, and recreation. Coastal dunes protect billions of dollars in property value along the nation’s coasts. Cultural and spiritual value For Indigenous communities and local cultures, wetlands and coastlines hold deep spiritual, cultural, and historical significance. Solutions that work Restoration projects Large-scale restoration efforts rebuild wetlands and dunes by planting native vegetation, reshaping landscapes, and removing invasive species. For example, Louisiana’s coastal restoration projects aim to rebuild lost marshes using sediment from the Mississippi River. Conservation easements Land trusts and government programs purchase development rights, protecting wetlands and dunes from being converted into urban or agricultural land. Policy protections Federal laws like the Clean Water Act and Coastal Zone Management Act provide critical protections, though enforcement varies. Strengthening these policies ensures wetlands and dunes receive long-term safeguarding. Community engagement Local stewardship programs empower citizens to monitor ecosystems, plant vegetation, and advocate for stronger protections. Climate adaptation strategies Communities are integrating wetland and dune conservation into climate adaptation plans, recognizing that natural infrastructure often outperforms artificial barriers. Five organizations leading the way 1. National Audubon Society Audubon works nationwide to protect birds and their habitats, with wetlands at the heart of their conservation efforts. Their coastal initiatives restore dunes, marshes, and tidal systems that provide critical bird habitat and climate resilience. 2. Ducks Unlimited Originally focused on waterfowl conservation, Ducks Unlimited now manages millions of acres of wetlands across North America. Their work includes habitat restoration, research, and advocacy for stronger wetland policies. 3. The Nature Conservancy The Nature Conservancy leads innovative conservation projects that protect wetlands, coasts, and marine environments. They partner with governments, businesses, and communities to secure long-term protection. 4. Sierra Club Foundation The Sierra Club Foundation supports grassroots activism and policy reform efforts to safeguard wetlands and coasts. They emphasize community engagement and climate action. 5. Coastal Restoration Trust Note: International reference, but supports U.S. partnerships The Coastal Restoration Trust promotes dune restoration through community projects, planting programs, and knowledge sharing. Their model has influenced similar efforts in the U.S. through partnerships and research. Stories of impact In Louisiana, restoration projects rebuilt wetlands that now buffer communities from hurricanes, reducing storm damage and saving millions in recovery costs. Along the Atlantic Coast, dune restoration projects in North Carolina stabilized beaches, protecting homes and businesses from rising seas. Ducks Unlimited’s conservation easements have permanently protected thousands of acres of prairie pothole wetlands in the Midwest, sustaining migratory bird populations. The Nature Conservancy partnered with New York communities to restore tidal wetlands that improve water quality and create recreational opportunities. Audubon volunteers planted native dune grasses along Gulf Coast beaches, helping rebuild habitats for endangered shorebirds. Policy solutions for stronger protection Strengthen enforcement of the Clean Water Act to prevent further wetland destruction. Expand funding for federal and state wetland restoration programs. Integrate wetland and dune conservation into national climate resilience strategies. Support Indigenous-led conservation initiatives that center cultural and ecological knowledge. Encourage private landowners to participate in conservation easements and incentive programs. What you can do today Donate to one of the organizations listed above. Volunteer with local dune or wetland restoration projects. Advocate for stronger wetland and coastal protections at the state and federal levels. Support sustainable development policies that prioritize ecological health. Reduce personal pollution by cutting plastic use and properly disposing of waste.

It is about safeguarding communities, preserving biodiversity, and confronting climate change with natural solutions. Every acre of restored wetland, every dune rebuilt with native grasses, strengthens our collective resilience. When we support organizations like Audubon, Ducks Unlimited, The Nature Conservancy, Sierra Club Foundation, and coastal restoration groups, we invest in a safer, healthier, and more sustainable future. Together, we can ensure that wetlands and dunes remain strong, protective, and life-giving for generations to come.
