Archive for 2012 Coastal Master Plan
By Eden Davis and Philip Russo, Mississippi River Delta Restoration Coalition
There are many reasons to advocate for coastal restoration in Louisiana, but few arguments are as compelling as preserving the cultural legacy of a state known for its food, music and festivities. That’s why we as part of the Mississippi River Delta Restoration Coalition are doing our best to celebrate tirelessly the cultural apex that is Mardi Gras in New Orleans. We, along with the rest of the community, line the sidewalks and neutral grounds of the boulevards where we share black cauldrons of jambalaya and generous portions of king cake. We gather to see and hear the spectacle that is the dance troupes, marching bands and ornate floats, but most importantly, we do it to feel the pulse of our community and to indulge in its vitality. We may have not always vocalized it as such, but it’s why we’ve always done it, going back all the way to the founding of the oldest and most venerable Krewe of Rex that rolls Mardi Gras morning.
The Krewe of Rex has held more parades than any other organization. They are the origin of many Mardi Gras traditions, including the official Carnival colors of purple, green and gold. Founded in 1872, Rex sought to attract new businesses and residents to a New Orleans that was struggling to recover from the lingering effects of the Civil War, when divisions and isolation prevailed. The founders knew the creation of a grand Mardi Gras celebration would lend itself to healing those wounds and restoring the unity that was such a prominent feature of this silted landscape. Most would agree that their efforts were an unbelievable success, but history has a way of repeating itself.
After Hurricane Katrina, this same story played out again as New Orleans struggled to rebuild not only its levees and homes, but its image. Today’s worries are not of the aftermath of a civil war, but of decades of tremendous land loss and increasingly devastating hurricanes. To ameliorate this, the state adopted a Comprehensive Master Plan for a Sustainable Coast. If enacted thoroughly, barrier islands, sediment diversions and marsh creation projects will, along with the efforts of Mardi Gras Krewes, not only sustain our coast, but also the traditions that makes it worth inhabiting. So we are doing our part, reveling when we can, sleeping when we can and asking everyone to join us in support of Louisiana’s Coastal Master Plan and coastal restoration. Happy Mardi Gras, y’all!No Comments

Soon after my flyover of the Mississippi River Delta, I joined Dr. John Lopez of the Lake Pontchartrain Basin Foundation (LPBF) on a boat ride down the Bohemia Spillway to Mardi Gras Pass. As we sped down the spillway canal, beautiful swamp lilies and purple morning glories popped out against a backdrop of lush, green plants. Once we reached our destination, we saw an incredible number of birds: Laughing Gulls, Snowy Egrets, Great Blue and Tricolored Herons – just to name a few. This, along with an increase in the number of river otters and beavers observed, is a good indicator that there are healthy fish populations in the area.
Thirty-five miles southeast of New Orleans, Mardi Gras Pass is the Mississippi River’s newest and naturally evolving “distributary,” a channel of water that flows away from the main branch of the river. This new distributary began forming during the spring flood of 2011, when the water level of the Mississippi River was so high that it flowed over the natural levee in this area. When the floodwaters receded, Dr. Lopez and his team of scientists noticed two breaches in the embankment. These breaches continued to widen and deepen and soon, right around Mardi Gras Day 2012, the breach was complete. The Mississippi River was once again connected to the surrounding wetlands, allowing freshwater and land-building sediment back into the area.
Louisiana has lost 25% of its coastal land area since 1930 and continues to lose land at an alarming rate – one football field every hour, on average. Man-made levees along the Mississippi River cut off many small distributaries, like Mardi Gras Pass, from the wetlands in the floodplain of the river and have contributed to this massive wetland loss. Our team here at EDF works with partner organizations, including the Lake Pontchartrain Basin Foundation, as part of the Mississippi River Delta Restoration Coalition, which has a vision of reconnecting the Mississippi River to its delta to help protect people, wildlife and jobs in coastal Louisiana.
To address the complex, yet urgent need for coastal restoration in Louisiana, the state legislature unanimously passed the 2012 Coastal Master Plan. This plan is a long-term, science-based restoration program that includes nearly 250 restoration projects such as barrier island restoration, marsh creation, establishment of oyster barrier reefs and sediment diversions that will help rebuild Louisiana’s disappearing coast.
Restoring our coast, restoring my hope
One of the principal guidelines for restoration under the Coastal Master Plan is to address the root causes of land loss by using the natural power of the Mississippi River to build land at a large scale. Sediment diversions, a central component of the plan, embody this principle because they are designed to mimic the natural stages of the river and carry sediment to the areas of coastal Louisiana that need it most. By operating diversions at times of high water flow (like during a flood), large amounts of sediment can be diverted. It will then settle out in the wetlands and shallow bays, eventually building land mass in vulnerable coastal areas.
In a way, Mardi Gras Pass is a naturally occurring ‘pilot project’ of a sediment diversion. Knowledge gained from studying this area can tell us about the land-building properties, as well as the short-term effects, of sediment diversions. To learn more about this, LPBF scientists are studying how the reintroduction of freshwater and sediment to the spillway area is changing the wetlands and affecting wildlife populations.
Swift currents and downed trees along the edge of the flooded forest can make navigating Mardi Gras Pass somewhat treacherous, but we, in a trusty 14’ skiff, maneuvered through the channel and onto the Mississippi River for a brief but thrilling cruise.
This is what it means for the river to be connected to its floodplain, I thought as we emerged out onto the open water, this is what this ecosystem is supposed to be like.
Although I grew up only a few miles from it, this was the third time in my life I had been out on the Mississippi River and the first time it was in a boat small enough that I could reach down and touch its muddy waters. As our tiny boat circled out in that mighty river, despite the heat and the midday sun, I had goose bumps.No Comments

Last week in Baton Rouge, The Water Institute of the Gulf hosted the inaugural meeting of the Expert Panel on Diversion Planning and Implementation. The panel – comprised of 12 experts in natural and social sciences, engineering and economics – was selected from more than 60 nominees from across the country. Panel members are all from outside Louisiana, in order to foster critical and constructive review of work being led by Louisiana-based experts. Under the direction of The Water Institute of the Gulf and meeting up to three times a year, this independent panel will provide technical review, input and guidance as the state moves forward and refines its plans for diverting fresh water and sediment from the Mississippi and Atchafalaya Rivers to build, maintain and sustain coastal wetlands. For this first meeting, the panel was asked to consider the most suitable approaches to addressing current or perceived uncertainties in the planning and design of sediment diversions.
The first day of this meeting was open to the public and included a series of presentations outlining the urgent need for restoration in coastal Louisiana as well as various perspectives on sediment diversions. Kyle Graham, Deputy Executive Director of the Coastal Protection and Restoration Authority (CPRA), summarized Louisiana’s 2012 Coastal Master Plan. In his presentation, Graham pointed out that there was no single restoration project type that can address the state’s land-loss crisis in one fell swoop, but that a suite of restoration projects are needed, including barrier island restoration, marsh creation, oyster barrier reefs, shoreline protection, hydrologic restoration and sediment diversions. Barrier island restoration and marsh creation can mechanically create land in strategic locations, but sediment diversions convey sediment to not only build new land but also to maintain existing wetlands that would otherwise be lost.
Brigadier General Duke DeLuca, Commander of the U.S Army Corps of Engineers’ Mississippi Valley Division, presented the Corps’ perspective on sediment diversions. DeLuca discussed some of the questions that the Corps would like to see answered as sediment diversions move from plan to implementation. Many of these outstanding questions should be directly addressed through the Mississippi River Hydrodynamic and Delta Management Study, a joint project being conducted by the State of Louisiana and the Corps. The study will use historic and field data, along with models, to do an assessment of large-scale restoration features to address sustainability of the Mississippi River Delta.
Additional presenters included Jim Tripp from Environmental Defense Fund, Michael Massimi from the Barataria-Terrebonne National Estuary Program, Dr. Ehab Mesehle from The Water Institute of the Gulf and Dr. Alaa Ali from South Florida Water Management District.
In a late afternoon panel, Mark Wingate and Martin Mayer of the Corps’ New Orleans District, John Ettinger of the Environmental Protection Agency and Ronnie Paille of U.S. Fish and Wildlife Service, discussed their federal agencies’ views on diversions. Afterwards, the public was given the opportunity to voice their thoughts and concerns about coastal restoration directly to the panel.
The following day, panel members met in private to discuss the uncertainties discussed and the science that needs to be done to address these uncertainties. A report on that meeting will be given at a CPRA meeting in the coming months.
Bold solutions are needed to halt the rate of catastrophic land loss in coastal Louisiana. Every year, communities throughout the coast inch closer to disaster, becoming more and more exposed to the destructive forces of storm events. Infrastructure, which is vitally important to the economy of Louisiana and the nation, becomes more vulnerable, and important habitat for wildlife, fish and birds vanishes.
Limited by money and sediment resources, there is no one type of restoration project that is a cure-all solution. A suite of restoration projects that strengthen and sustain the landscape is necessary. Sediment diversions use the natural power of the river to build new land and help maintain the existing wetlands. To do nothing or to only implement the least challenging types of restoration projects would doom the resource-rich Louisiana coast.No Comments

It is hard to say no to a good two-for-one deal. At least, that’s what Louisiana’s Coastal Restoration and Protection Authority (CPRA) had in mind when they planned this week’s public meetings in South Louisiana.
At meetings in Belle Chasse (yesterday), Thibodaux (tonight) and Lake Charles (tomorrow evening), CPRA is unveiling and accepting public comments on their Draft Fiscal Year 2015 Annual Plan as well as the Gulf oil spill Draft Natural Resource Damage Assessment (NRDA) Programmatic Environmental Impact Statement (PEIS) and Phase III Early Restoration Plan.
To kick off the tour, more than 100 people attended the Belle Chasse meeting last evening. CPRA’s Deputy Executive Director, Kyle Graham, began the two-hour joint meeting by presenting Louisiana’s Draft FY2015 Annual Plan. Graham described the implementation of the Louisiana Coastal Master Plan as a “50-year program, at least.” He qualified this by saying that “We live in an engineered landscape, and it’s going to be much longer than that. We know that this is a program that needs to go on for as long as we choose to live in this engineered landscape.” He outlined the multi-layered suite of restoration projects the CPRA is designing, engineering and constructing and emphasized that “we are in the middle of the largest restoration construction boom in the state’s history.” He also pointed out that the suite of coastal restoration projects will soon include sediment diversions.
Sediment diversions were a popular topic of discussion during the Draft FY15 Annual Plan public comment period. Some attendees expressed their view that diversions will bring more harm than good for fish and oyster habitats. Conversely, John Lopez of the Lake Pontchartrain Basin Foundation expressed that without the full suite of coastal restoration projects, which includes sediment diversions, “all of our livelihoods down here in South Louisiana are potentially at stake; it’s not one particular sector.”
The close of the Annual Plan public comment session transitioned right into the NRDA PEIS and Phase III Early Restoration Plan portion of the meeting. Residents were updated about various projects being funded by the $1 billion made available by BP for early NRDA restoration. Though all funds stemming from the BP oil disaster are to be split between the five Gulf Coast states, they can only be used for projects that are designed to restore or enhance recreational and ecological activity along the Gulf. In Louisiana, the main four projects featured in the presentation were barrier island restoration projects in the Caillou Lake Headlands, Chenier Ronquille, Shell Island and North Breton Island.
Though some public comments were made following the NRDA section, it lacked the intensity of the first round. Regardless, the back-to-back meeting was a great opportunity for local residents, politicians and advocates alike to participate in Louisiana’s coastal planning process.1 Comment

With everyone’s help, we are making great strides toward restoring Louisiana’s coast. Our efforts to attain the resources necessary to meet this great challenge are gaining momentum and projects are moving forward. Next week on January 14, 15, and 16, Louisianans will be able to learn about and comment on the progress being made on coastal restoration at three multi-purpose public hearings being held by Louisiana’s Coastal Protection and Restoration Authority (CPRA).
The first section of each meeting will be an opportunity to hear a summary presentation of the CPRA’s Draft Fiscal Year 2015 Annual Plan and make comments on the plan. Each year, the Annual Plan details how the 2012 Coastal Master Plan is being implemented, reports on the status of ongoing work and projects and provides a 3-year projection of expenditures, as required by law. The Annual Plan provides a window into how the CPRA is allocating its resources in the short term, within the context of the long-term, big-picture vision of the overall Coastal Master Plan.
The second half of the meeting will widen the focus to include Gulf-wide coastal restoration plans and projects. The National Oceanic and Atmospheric Administration (NOAA) and the Deepwater Horizon Natural Resource Damage Assessment (NRDA) Trustees will give a presentation on and listen to public comments regarding the Draft Programmatic and Phase III Early Restoration Plan and Draft Early Restoration Programmatic Environmental Impact Statement. This meeting is an opportunity for the public to comment on the third and final set of projects proposed to address oil spill impacts under the Early Restoration Plan as well as the Environmental Impact Statement that assesses the projects themselves.
All meetings are public and will begin with an open house at 5:30 p.m., followed by presentations beginning at 6:00 p.m. Please consider joining us at one of the following meetings. If you’re interested in attending, please contact our field director, Stephanie Powell, at firstname.lastname@example.org.

I was struck by a line in an article in the new issue of Scientific American. It called the loss of Louisiana’s coastal wetlands “the greatest environmental, economic and cultural tragedy on the North American continent.”
It’s easy to see why they would say that. Since the 1930s, efforts to control the Mississippi River and widespread energy development in the delta have resulted in the sacrifice of 1,900 square miles of Louisiana’s coastal wetlands to the sea. If that had happened on the east coast, an area twice the size of Boston, New York City, Philadelphia and Washington, D.C. put together would be under water. Of course, the engineering projects on the Mississippi spurred over a century of economic development and navigation. But the cost has been the loss of the original delta ecosystem, leaving coastal communities more exposed to storm surges and a rising sea level.
As dramatic as that is, the thing that caught my eye even more was another line in the Scientific American article: “Many wetland recovery programs have failed by trying to re-create the original ecosystems.”
The article goes on to make a point that we don’t have to re-create the past to make things better for people and the planet. In fact, when you think clearly and specifically about the need we as a society are trying to meet, and then ask how nature can help meet that need, surprisingly positive things can happen.
Consider Scientific American’s example of the Delaware Bay, an ecosystem that was teeming with aquatic life before settlers built dikes and drained thousands of acres to grow crops.
“Looming on the New Jersey shore of the bay is the Salem nuclear power plant, owned by utility giant PSEG. The plant sucks in billions of gallons of water a day for cooling and kills millions of tiny fish and other creatures as they get drawn through the intake valves. In the early 1990s state regulators asked PSEG to build cooling towers to end the carnage. Reluctant to spend $1 billion to $2 billion, the utility proposed an alternative: restore enough salt marsh to compensate for the loss of fish — more than 10,000 acres.”
The restoration team decided to take a less-is-more approach — cut gaps in the dikes that would let just the right amount of water into the marsh to create an initial maze of tidal creeks, and then let the rest of the creeks develop on their own. “If you engineer a drainage system in great detail, the system is forced to go the way you think it ought to be,” a restoration expert told the publication. “But if you allow it to develop itself, it’s more likely to be stable.”
Today, reports Scientific American, the increase in fish populations more than makes up for the losses from the power plant’s water intake, and the restoration looks like the natural marshes next door. Plus, it saved consumers money because letting nature meet the need cost hundreds of millions of dollars less than the concrete cooling towers.
You see this principle at work in the efforts of EDF and our allies in the Gulf of Mexico. Last year, as part of ongoing efforts to reverse losses in the Mississippi River Delta, Louisiana passed the Comprehensive Master Plan for a Sustainable Coast. This landmark plan serves as the blueprint for restoring Louisiana’s wetlands, and it follows two tenets that proved so successful in the Delaware Bay. First, it focuses on a single goal: rebuilding and sustaining hundreds of square miles of land. Secondly, it relies on nature to do the bulk of the reconstruction. Sediment-laden water from the Mississippi River will be diverted into marshes and shores. Over time, the sediment will create new land and a more resilient coastline.
In the face of extreme weather and global sea-level rise, this new approach takes on great meaning. Superstorm Sandy provided powerful illustrations of how wetlands can serve as a first line of defense against extreme weather events. Salt marsh remnants along Long Island’s Jamaica Bay, for example, helped to protect residents there, while the lack of wetlands around Manhattan left it exposed to crashing waves.
More than 3 billion souls — 40 percent of the world's population — live as close to the sea as New Orleans. By letting nature back into the game, we can help rebuild coastal Louisiana and turn “a North American tragedy” into a model of success for protecting nearly half the planet’s population.

Excitement filled the air last Friday as community members, government officials, students and staff from local and national conservation organizations gathered on the Bayou Bienvenue Wetland Triangle viewing platform in New Orleans’ Lower Ninth Ward to celebrate the unveiling of new educational, interactive signs. These signs help interpret an important story for visitors as they look out over the open water and ghostly remains of a former healthy cypress swamp. At this powerful site, in the backyard of a community less than five miles from the French Quarter that was devastated by Hurricane Katrina, visitors will learn about efforts to restore the Bayou Bienvenue ecosystem as well as the broader, critical need for coastal restoration. The signs were a project of The Lower Ninth Ward Center for Sustainable Engagement and Development and the Mississippi River Delta Restoration Campaign.
In addition to the four National Park Service-grade signs, a new website, www.restorethebayou.org, was also created to accompany the signs. On the site, visitors can learn more about the history of Bayou Bienvenue; read about the vision for restoration of the wetland triangle as well as broader Louisiana coastal restoration; learn about community and environmental organizations working to restore the wetlands; watch videos in the multimedia gallery; sign the virtual guestbook by taking a photo using Instagram and adding the hashtag #restorethebayou; and take action by signing a petition to decision-makers, asking them to prioritize MRGO-area restoration projects – like the Bayou Bienvenue Wetland Triangle.
The dozens of people in attendance heard from Garret Graves, Chair of Louisiana’s Coastal Protection and Restoration Authority, who proclaimed the importance of the platform and signs when he said, “This is such an important teaching tool for us…it’s a microcosm of what is happening on a huge scale in coastal Louisiana.”
Other speakers included Charles Allen, Director of the City of New Orleans’ Office of Coastal and Environmental Affairs; Arthur Johnson, Executive Director of the Lower Ninth Ward Center for Sustainable Engagement and Development; and Amanda Moore, Greater New Orleans Program Manager for the National Wildlife Federation, speaking on behalf of the Mississippi River Delta Restoration Coalition.
Get involved! Check out Restore the Mississippi River Delta’s Facebook album of photos from the unveiling event, and visit www.restorethebayou.org to learn more about the Bayou Bienvenue Wetland Triangle and coastal restoration efforts.No Comments
Mississippi River Delta Restoration Coalition submits comments on proposed RESTORE Act Treasury regulationsNovember 19, 2013 | Posted by Delta Dispatches in 2012 Coastal Master Plan, BP Oil Disaster, Gulf Coast Ecosystem Restoration Council, RESTORE Act
By Whit Remer and Elizabeth Weiner, Environmental Defense Fund
Earlier this month, the Restore the Mississippi River Delta Coalition submitted public comments to the U.S. Department of Treasury (Treasury) on a proposed rule governing disbursements from the Gulf Coast Ecosystem Restoration Trust Fund. The Trust Fund was established by the RESTORE Act, enacted in 2012, and is funded by 80 percent of the civil Clean Water Act penalties that have been, and will be, paid by the parties responsible for the 2010 Deepwater Horizon oil disaster. The Act mandates that the Trust Fund be housed within and managed by Treasury and requires that Treasury propose and finalize a rule, with input from the public, regarding its management protocols. This is common practice for federal trust fund management. It is important because funding cannot be disbursed from the Gulf Coast Ecosystem Restoration Trust Fund for urgently needed Gulf restoration until the rule promulgation process is complete.
Multiple federal rules, developed in similar manners, are necessary to implement the RESTORE Act. They may overlap with other implementation documents and reiterate statutory language. We believe that when overlap exists, the entities involved should ensure as much consistently and clarity as possible. For example, the RESTORE Act language and the Final Initial Comprehensive Plan direct the Gulf Coast Ecosystem Restoration Council’s funding allocation exclusively to ecosystem restoration projects. Our comments suggested that the language and instruction in the final Treasury rule could more clearly reflect that specific direction from Congress and the Council.
As part of its management role, Treasury must also develop a compliance and auditing program – compliance on the front end to verify that grant applications comply with statutory requirements, and auditing on the back end to ensure that applicants did what they said they would do with the funds. Within Treasury, the Treasury RESTORE program will handle some aspects of this, and Treasury Inspector General will handle others. Because of the RESTORE Act’s unique structure with different funding components, the Council also has compliance and auditing authorities. Our comments urged Treasury to more clearly delineate the compliance and auditing roles of each of these federal entities so as to minimize delays and duplication and maximize the amount of funding that can be spent directly on restoration efforts.
Our comments also encouraged Treasury to consider adopting Louisiana’s 2012 Coastal Master Plan as the RESTORE Act’s mandatory state expenditure plan. To receive funds from the Spill Impact Component, states must submit a multi-year expenditure plan that describes each program, project and activity for which the state seeks funding. Due to Louisiana’s substantial land loss crisis, the state has already developed a science-based planning process. The most recent product of that process is the 2012 Master Plan for a Sustainable Coast. The State of Louisiana has dedicated, by state law, all funds from the RESTORE Act to its constitutionally protected Coastal Restoration and Protection Fund to be spent solely on projects in this plan. Recognizing that projects in the master plan still have to be sequenced for the purpose of serving as a RESTORE multi-year plan, we have advocated that the Plan meets, and often exceeds, the requirements of the State Expenditure Plan. If Treasury accepts the master plan process as compliant with the process set forth in the rule, the State of Louisiana will be ready to apply for RESTORE funds and utilize grant dollars more quickly.
Over the next few weeks, Treasury will read and consider comments submitted by the public as they prepare the final rule for the Gulf Coast Ecosystem Restoration Fund. The Council will also have to promulgate a rule regarding the RESTORE Act Spill Impact Component.No Comments
National Fish and Wildlife Foundation Announces Nearly $68 Million for Louisiana Restoration ProjectsNovember 14, 2013 | Posted by Ryan Rastegar in 2012 Coastal Master Plan, Media Resources, Mid-Barataria Sediment Diversion, Restoration Projects

National Fish and Wildlife Foundation Announces Nearly $68 Million for Louisiana Restoration Projects
$40.4 million dedicated to Mid-Barataria Diversion, a critical project to comprehensive coastal restoration
(New Orleans, LA – November 14, 2013) Today, leading national and local conservation and restoration organizations – Environmental Defense Fund, National Audubon Society, National Wildlife Federation, Coalition to Restore Coastal Louisiana and the Lake Pontchartrain Basin Foundation – released the following joint statement:
“We applaud the National Fish and Wildlife Foundation (NFWF), in partnership with Louisiana’s Coastal Protection and Restoration Authority, for dedicating $67.9 million to seven key barrier island and river diversion projects, including $40.4 million for the Mid-Barataria Diversion project. The Barataria Basin has one of the highest rates of land loss in the world, and this large-scale wetland restoration project is crucial to reversing that trend.
“The mid-sized Mid-Barataria sediment diversion is a key component of Louisiana’s 2012 Comprehensive Master Plan for a Sustainable Coast. The master plan is a blueprint for restoring the Mississippi River Delta and Louisiana’s coast and contains a suite of coastal restoration and protection projects. Our organizations support the full suite of restoration projects in that plan, of which the Mid-Barataria Diversion is a critical piece.
“Restoration of Louisiana’s disappearing wetlands is important not only to Louisiana but to the entire nation. Louisiana’s wetlands and waters provide one-third of the nation’s seafood, are a stopover point for migratory birds traveling the Mississippi Flyway and provide critical wildlife habitat. Projects like the Mid-Barataria Diversion can help revive Louisiana’s coastal wetlands – part of America’s largest delta – to a productive, functioning state, which provides important ecological and economic opportunities for people and wildlife. We look forward to continued work with both the National Fish and Wildlife Foundation and the State of Louisiana to implement the Mid-Barataria sediment diversion on its current timeline of being ready for construction in 2015.”

Since 2009, the Lake Pontchartrain Basin Foundation (LPBF) has been actively documenting the development of an emergent delta in the receiving basin, Big Mar, of the Caernarvon Diversion outfall canal on the east side of the Mississippi River south of New Orleans. Since October 2010, in partnership with the Coalition to Restore Coastal Louisiana (CRCL), LPBF has conducted tree plantings within Big Mar as part of a Restore the Earth Foundation grant-funded reforestation effort, called 10,000 Trees for Louisiana.
The Lake Pontchartrain Basin Foundation and the Coalition to Restore Coastal Louisiana conducted a 7th tree planting in Big Mar on October 28, 2013. This planting was conducted as a restoration event opportunity for members of the Mississippi River Delta Restoration Campaign. All of the volunteers were people who work on various parts of the campaign and included staff from Environmental Defense Fund, National Audubon Society, National Wildlife Foundation, LPBF and CRCL.
Twenty-five people, including 18 volunteers and 7 staff, planted a total of 250 trees at five different sites. Two of the sites, with 25 trees planted at each, are demonstration sites. If trees grow successfully at these locations, then future plantings will occur there with many more trees. 125 bald cypress trees (Taxodium distichum) and 125 water tupelo trees (Nyssa aquatica) were planted. Photos from the event can be seen on the Restore the Mississippi River Delta Facebook page and the Coalition to Restore Coastal Louisiana Facebook page.
The focus of these volunteer events is to plant trees that will abate and reduce storm surge. Big Mar is located directly in front of the newly built Hurricane and Storm Damage Risk Reduction System Levees, and a thriving cypress forest will provide some protection to this levee system by buffering storm surge. Big Mar is also located in front of the Braithwaite community, which is outside the federal levee system but has local levees that were overtopped and breached during Hurricane Isaac. A swamp forest in front of that community would provide some storm surge attenuation benefit. Additionally, monitoring the growth of these trees under the influence of the Caernarvon Diversion, at different distances from the diversion, will provide valuable information for future restoration projects. The work being done around the Caernarvon Delta Complex provides a unique opportunity to test the effectiveness of many proposed 2012 Louisiana Coastal Master Plan restoration initiatives, which rely heavily on river diversions.
Ultimately, if the data bears out and the hypothesis is true that the sediment delivered by river diversions builds land – and that the fresh water flowing into a receiving basin lowers soil salinity and the nutrients associated with river water increase growth rates – then this information could be used to manage river diversions more effectively in the future in an effort to do what they are supposed to do, which is to build wetlands that will help sustain coastal Louisiana and protect its people and communities from devastating storm surges.No Comments
