How Louisiana’s Coastal Wetlands and Wildlife Endured the Unusual Cold Snap

Louisiana’s coastal wetlands, known for their subtropical climate, rarely experience snow or extreme cold. However, a recent winter storm in early 2025 brought an unusual blanket of snow to the region, prompting concerns about its impact on the state’s delicate coastal ecosystems. While some wildlife and plant species may have been affected, experts assured that the wetlands themselves were unlikely to suffer significant damage, as per this article from The Advocate.

One of the most immediate consequences of the cold snap was the reported fish kills along Louisiana’s coastal wetlands. Certain fish species, particularly those not native to the state, struggled to survive the sudden temperature drop. The rapid decline in water temperature appeared to have been the primary cause, as fish are highly sensitive to abrupt environmental changes. While some species faced challenges, others demonstrated resilience. Alligators, for instance, were largely unaffected by the cold. According to Chris Schieble, deputy assistant secretary of fisheries at the Louisiana Department of Wildlife and Fisheries, alligators had already entered a hibernation-like state known as brumation. They remained buried in their mounds, conserving energy and avoiding exposure to the frigid temperatures.

Similarly, native birds to our coastal wetlands may have experienced initial confusion due to the unusual conditions, but experts believed they would adapt without long-term harm. Other cold-hardy swamp creatures, such as river otters, were also expected to remain largely unaffected.

The snow-covered landscape presented an unusual sight for Louisianans, with palmettos, bald cypress trees, and live oaks weighed down by frost and icicles. Though some plants might suffer damage, Robert Twilley, a coastal sciences professor at LSU, expressed confidence that most native plant populations would recover quickly.

One species of concern, however, was the black mangrove. These subtropical plants, which have expanded across Louisiana’s coastline since the 1980s due to warming temperatures, are highly sensitive to frost. Twilley noted that while some black mangroves would likely die, he had been surprised in the past at their ability to recover.

Andrew Ferris, coordinator of the native plants program at the Coalition to Restore Coastal Louisiana, expected some mangrove losses but reassured that other native species would fare well. He visited a site in St. Bernard Parish where 2,000 bald cypress and water tupelo trees had been planted for coastal reinforcement. Since these trees are native to South Louisiana, they were well adapted to withstand cold snaps and occasional snowfall.

While native species demonstrated resilience, the freezing temperatures might have benefited Louisiana’s wetlands in another way—by reducing invasive species populations. Nutria, the destructive rodents native to South America, struggled in the cold, with many perishing due to their inability to adapt to sudden temperature drops. Schieble noted that these animals, which are notorious for devouring wetland vegetation, were unlikely to survive prolonged exposure to freezing weather.

Other invasive species in the states’ coastal wetlands, including water hyacinth and giant salvinia—both of which overtake Louisiana’s waterways during warmer months—were also expected to suffer significant die-offs. Since these plants are not cold-tolerant, experts predicted that the frigid weather would provide a temporary reprieve from their rapid spread.

However, not all coastal wetlands invasive species were impacted. Feral hogs, known for their ability to destroy vegetation and disrupt wetland ecosystems, were expected to survive. Schieble explained that their thick winter coats allowed them to withstand cold temperatures, making them one of the few unwelcome species that would persist despite the harsh conditions.

Overall, Louisiana’s coastal wetlands and wildlife proved resilient in the face of this rare cold event. While certain species, particularly non-native plants and animals, faced temporary losses, the foundational elements of the ecosystem remained intact. Scientists and conservationists will continue monitoring the effects of the cold spell, particularly on fish populations and the survival of black mangroves. However, for the most part, Louisiana’s wetlands emerged from the winter storm with their long-term stability unshaken.

Saving Grand Bayou: How Recycled Shells Are Fighting Erosion

Louisiana’s ongoing land loss crisis continues to devastate communities along its coastline, and nowhere is this more evident than in Grand Bayou. Home to the Atakapa-Ishak/Chawasha tribe, this remote village in Plaquemines Parish has seen dramatic changes over the last century, as per this news report from Fox-8. In the 1940s, the vibrant community housed nearly 1,000 residents. Today, it consists of just a handful of stilted homes accessible only by boat. However, a recent initiative involving recycled oyster shells has brought renewed hope to this fading community.

For decades, coastal erosion and rising sea levels have reshaped the landscape of Grand Bayou, once a thriving settlement surrounded by marshland. Since 1932, Louisiana’s coastline has lost almost 2,000 square miles of land. Grand Bayou has suffered disproportionately, with its land-to-water ratio steadily declining over the past 60 years. By 2011, a study by the Journal of Coastal Research found the village to have one of the highest rates of land loss along the state’s coastline.

Rosina Philippe, a tribal elder and knowledge keeper, recalled that life in Grand Bayou once provided everything residents needed—land for farming, water for fishing, and resources for bartering. But decades of land erosion and saltwater intrusion have upended this way of life. “We’re losing habitat,” she said, noting how the disappearance of marshlands has affected not only human life but also wildlife, including birds and fish.

In September, the Coalition to Restore Coastal Louisiana (CRCL) partnered with the Atakapa-Ishak/Chawasha tribefor an innovative project to combat shoreline erosion. Over four days, volunteers built reefs using recycled oyster shells collected from New Orleans and Baton Rouge restaurants. These 30-pound bags of shells were strategically placed along the shoreline to act as natural barriers, reducing wave energy and stabilizing the banks.

The use of oyster shells offers a dual benefit. Unlike rocks, the shells foster the growth of living reefs as baby oysters attach to them. Over time, these reefs create an ecosystem that attracts fish, crabs, and other marine life. Darrah Fox Bach, a CRCL program coordinator, emphasized that recycled shells are an environmentally friendly alternative to landfills. “Instead of sending them to a landfill, put them back in the water,” she explained.

According to CRCL staff, similar projects have shown significant success. Oyster reefs not only reduce shoreline erosion by up to 50% but also support thriving marine communities. This natural approach provides a glimmer of hope for Grand Bayou, where high-tech solutions are often financially out of reach.

This was not the first collaboration between the tribe and the CRCL. In 2022, they worked together to protect Lemon Tree Mound, a sacred site historically used for offerings to ancestors. A reef built around the mound has already led to the return of aquatic life, including snails, crabs, and oysters.

The significance of Lemon Tree Mound was further highlighted in September when St. Paul’s Episcopal Churchreturned the land to the tribe. The church had held the property in trust since 1991 but decided to return it after learning of its cultural importance. The Rev. Marian D. Fortner described the rematriation as an acknowledgment of the land’s rightful stewards. In gratitude, the tribe gifted the church a handmade blanket, symbolizing a growing solidarity between Indigenous and non-Indigenous communities.

While Grand Bayou may never return to its former state, the oyster reefs provide a tangible way to preserve what remains. More importantly, they represent a beacon of hope for a community that has long been marginalized. As Philippe noted, “When you’re a small community, sometimes it’s difficult to be heard or be invited at the table.” The success of these projects not only safeguards the environment but also ensures that the voices of Indigenous communities remain part of the conversation.

Collaborative Efforts in Coastal Protection: CPRA’s 2024 Awards

The Coastal Protection and Restoration Authority (CPRA) of Louisiana announced six recipients of the 2024 Parish Matching Program awards, totaling a combined $7 million. This initiative, designed to support local governments in their coastal restoration efforts, highlights a collaborative approach between the state and parish governments to address pressing environmental concerns, according to this article from The Houma Times.

CPRA Executive Director Glenn Ledet, Jr. expressed his enthusiasm about the partnership with local governments, emphasizing the alignment of these projects with the Coastal Master Plan. He pointed out that the infusion of state and local funds would expedite the implementation of critical projects, thereby enhancing protection for residents and improving coastal ecosystems in Louisiana.

For the fiscal year 2024, the funding was allocated on a reimbursement basis, sourced from state surplus funding and the Gulf of Mexico Energy Security Act (GOMESA) funds. The awarded projects cover a broad spectrum of restoration efforts across various parishes, each addressing unique environmental challenges.

Jefferson Parish received funding to elevate approximately 22 homes in Lafitte and Grand Isle, which had been approved by FEMA for non-structural improvements. Additionally, the grant provided matching funds to plant four acres of dunes along a two-mile stretch of Grand Isle. This effort aims to enhance the resilience of these areas against future storms and flooding.

In Lafourche Parish, the funding was allocated to construct over 36,000 linear feet of earthen terraces to restore more than 200 acres of marsh along Bayou L’Ours. This area had been significantly degraded by Hurricane Ida, and the terraces would help in mitigating further erosion and promoting marsh recovery.

St. Bernard Parish was awarded funds to support the creation of over 400 acres of marsh and restore 2.5 miles of lake rim along Lake Lery. This project is vital for preserving the lake’s ecosystem and preventing further degradation of the marshland.

St. John the Baptist Parish’s allocation was designated for designing, engineering, and constructing approximately five spoil bank gaps near Bayou Chevreuil. These gaps would help reduce impoundment and enhance the health of around 1,800 acres of cypress-tupelo swamp, promoting better water flow and ecological balance.

St. Tammany Parish received funding to develop and construct approximately 505 linear feet of living shoreline along Goose Point. This project, part of the St. Tammany Living Shorelines initiative, aimed to stabilize the shoreline and protect it from erosion while providing habitat for marine life.

Lastly, Vermilion Parish was granted funds to build over one mile of additional rock breakwater to protect the eroding marsh along Vermilion Bay. This structure is essential for shielding the marshlands from the erosive forces of waves and tides.

The CPRA stands as the primary state entity responsible for coastal protection and restoration in Louisiana. Its mandate includes developing, implementing, and enforcing a comprehensive coastal protection and restoration Master Plan. This cohesive strategy integrates the expertise and resources of various state departments, such as the Department of Natural Resources and the Department of Transportation and Development, to address the multifaceted challenges of coastal restoration and hurricane protection.

For the first time in the state’s history, a single authority is harmonizing efforts across federal, state, and local levels to articulate a unified vision for Louisiana’s coastal future. This integrated approach aims to establish a safe and sustainable coast that safeguards communities, critical energy infrastructure, and the state’s abundant natural resources.

By collaborating with federal entities, local political subdivisions, and levee districts, the CPRA is working towards a resilient coastline. Their efforts are crucial for protecting not only local communities but also the nation’s energy infrastructure and natural resources, ensuring they remain robust for future generations.

Vinot’s reflections offer a glimpse into the island’s evolution, from its heyday as a bustling commercial hub to its current status as a haven for those seeking solace by the water. His recollections paint a vivid portrait of a community bound by shared struggles and triumphs, united in their determination to preserve their way of life against the tide of change.

Zooming out from the island’s shores, the broader landscape reveals the intricate interplay of natural forces that haveshaped Louisiana’s coast over millennia. Richard Campanella’s insights into the region’s geological history provide a deeper understanding of the challenges facing the landbridge—a critical lifeline for the communities it serves.

As Joseph Wyble of the Coastal Protection and Restoration Authority underscores, the fate of the landbridge extends far beyond the confines of the island, impacting communities across the region. Marsh restoration efforts offer a glimmer of hope, yet the road ahead is fraught with uncertainty, requiring a concerted effort to secure the future of Louisiana’s coast.

In the face of mounting challenges, voices like Milton Dudenhefer’s serve as a poignant reminder of the urgent need for action. His lifelong connection to the island and its waters lends credence to his impassioned plea for awareness and solidarity in the fight against coastal erosion. The island may be a mere speck on the map, but its fate is intertwined with that of Louisiana’s coast—a story of resilience, adaptation, and the enduring bond between land and sea.
