It’s been more than five years since the Deepwater Horizon oil rig exploded. Since that time, a council of federal and state Trustees have been extensively investigating the impacts of the disaster on wildlife and habitats, but that information has been kept under wraps—for use in litigation against BP. Now that the case has settled, this research has finally been made public in a draft Programmatic Damage Assessment and Restoration Plan.
The impacts to wildlife and their habitats are shocking and far reaching. Despite clean-up efforts and the natural weathering processes over the five years since the spill, oil persists in some habitats where it continues to expose resources in the northern Gulf of Mexico. In many cases, the damage to wildlife and habitats was more severe than previously understood. The ecological linkages of these habitats and communities and their connectivity to the larger Gulf of Mexico ecosystem can result in cascading impacts, influencing the overall health and productivity of the Gulf of Mexico ecosystem.
Together, the National Wildlife Federation and Ocean Conservancy scientists have worked to dig in to the massive report and digest its findings. Here is a snapshot of the types and severity of impacts outlined in the draft report.
While the Trustees acknowledge that this is a very conservative estimate, the total number of birds killed by the BP oil disaster is from 56,100 to 102,400 birds. At least 93 species of birds across all five Gulf Coast states were exposed to oil.
2. Beach & Dune Habitat
BP oil covered at least 1,300 miles of the Gulf coastline, including 600 miles of beach, dune and barrier island habitat.
3. Lost Human Use
The public lost 16,857,116 days of boating, fishing and beach-going experiences. The total loss of recreational use of the Gulf due to the disaster is worth $528 million to $859 million.
Between 4 and 8.3 billion oysters are estimated to have been lost. Over three generations (minimum recovery time), the dead oysters would have produced a total of 240 to 508 million pounds of fresh oyster meat.
5. Salt Marsh
Louisiana lost up to 53 percent of its salt marsh plants across 350-721 miles of shoreline. In Louisiana wetlands, erosion rates approximately doubled along at least 108 miles of shoreline. The effect lasted for at least 3 years.
Sargassum, a floating seaweed that provides habitat for young fish and sea turtles, was exposed to oil, which may have caused the loss of up to 23 percent of this important habitat.
7. Seagrass Habitat
Seagrass beds covering a total area roughly the size of 206 football fields (272 acres) were lost from the time of the disaster through 2012.
8. Larval Fish
The Trustees estimated that 2-5 trillion larval fish were killed. The loss of larval fish likely translated into millions to billions of fish that would have reached a year old had they not been killed by the BP oil disaster.
9. Sea Trout
Several of species of sea trout, including the spotted (or speckled) sea trout, were severely impacted by the disaster. An estimated 20-100 billion sea trout larvae were killed as a result of the disaster.
The growth of young white, pink and brown shrimp was dramatically affected by oil. The total loss of shrimp production over 2010 and 2011 due to oiling is estimated at more than 2,300 tons.
11. Red Drum
The growth of young red drum fell by up to 47 percent along marsh shorelines in Louisiana that were persistently oiled since 2010, and an estimated 700 tons of red drum were lost. Reduced red drum production persisted through 2013 and is expected to continue.
While nearly all of the species of whales in the footprint of the oil have demonstrable, quantifiable injuries, the most hard-hit was the Bryde’s whale. With only about 50 Bryde’s whales left in the Gulf, roughly half of these animals were exposed to oil—and nearly a quarter were killed. It is unclear if Bryde’s whales will be able to recover.
13. Bottlenose Dolphins
The number of bottlenose dolphins in Barataria Bay and Mississippi Sound—two areas particularly affected by the disaster—is projected to decline by half. The populations are expected to take 40-50 years to recover. In the 5 years after the oil disaster, more than 75 percent of pregnant dolphins observed within the oil footprint failed to give birth to a viable calf.
14. Coral Reefs
The footprint of injury to mid-depth coral reefs is just over 4 square miles. These areas along the continental shelf edge, known as the Pinnacles, showed extensive damage to both the coral colonies and the reef fish associated with them. The larger ecological functions of this habitat were very likely impaired.
15. Sea Turtles
All five of the Gulf’s sea turtles are either threatened or endangered. It is estimated that somewhere between 61,000 and 173,000 sea turtles—of all ages—were killed during the disaster. For the endangered Kemp’s ridley sea turtle, this equals 10-20 percent of the average number of nesting females each year, which would have laid approximately 65,000 – 95,000 additional hatchlings.
16. Deep Seafloor
The footprint of BP oil on the Gulf seafloor around the wellhead is an area more than 20 times the size of Manhattan (over 770 square miles). An additional 3,300 square miles may have been affected.No Comments

Today is National Oyster Day, and we’re celebrating the holiday with a post about these useful and tasty bivalves and the University of Maryland Center for Environmental Science’s (UMCES) Horn Point Laboratory, which is growing them by the billions.
Previous posts have discussed the ecological and economic importance of oysters, so we won’t spend time on this today. In preparation for a series of other posts on the (r)evolutionary oyster industry, this post will explain their life history and introduce some of the research being conducted to ensure their continued success.
Oysters grow in large colonies that make up reefs. Mature oysters begin to spawn when the water temperature reaches 74-86 degrees Fahrenheit. When the first male or female spawns, others sense it as they filter the water, thus triggering more to spawn.
The sperm and eggs join in the water column. The newly formed larvae will swim and feed for approximately two weeks until they reach what’s known as the pediveliger stage and are ready to attach to a substrate, a process known as “setting.” When an oyster sets, it secretes a glue-like substance and will not move from this location for the duration of its life. At this point, the oyster is known as a spat.
In the lab, this process is much the same as in the wild, however, it takes place in a controlled environment. In this environment, staff are able to control variables such as temperature, salinity and food availability – variables which have tremendous effects on oyster spawning and survival rates.
Aside from their work in growing oysters, the UMCES Horn Point Hatchery is a hotspot for research on all things oyster, including numerous graduate student researchers looking into how salinity affects setting and growth throughout oysters’ lives. Having a good understanding of optimal salinities and answering these questions, we remove yet another unknown in this industry, allowing greater understanding for how to ensure oysters are able to thrive now and into the future.
Oyster populations and harvests are on the rise in the Chesapeake Bay for the first time in decades. In 2004, just 26,000 bushels were harvested from Maryland’s waters. In 2014, Chesapeake Bay harvesters reported their best year in three decades, bringing in 900,000 bushels from traditional on-bottom leases.
What’s the cause of this rebounding industry? It’s no miracle cure, but rather a host of federal and state management practices, a booming aquaculture industry, successful hatcheries that provide a reliable source of larvae and new science that is allowing these bivalves to thrive once again.
What does this mean for Louisiana? Our coastal waters boast some of the best conditions for oyster growth in the nation. Using funds from the Natural Resources Damages Assessment (NRDA) Early Restoration Program, LSU Sea Grant is operating a new, state of the art hatchery on Grand Isle, a hatchery capable of producing up to one billion oyster larvae per year. This increased capacity can add significantly to the production potential of the state’s public and private oyster grounds. Additionally, off-bottom aquaculture and remote setting are looking more and more like realistic options to increase the industry’s success. Stay tuned for future posts about each of these new tools in the oyster industry’s toolbox.

Final Phase of BP Oil Spill Trial to Begin Next Week
BP must be held fully accountable for its role in nation’s largest oil disaster
(New Orleans – January 15, 2015) On Tuesday, January 20, 2015, the third and final phase of the BP oil spill civil trial will begin in New Orleans. This concluding portion of the trial will determine how much BP will be required to pay in Clean Water Act fines for its role in the 2010 Gulf oil disaster.
National and local conservation organizations committed to Mississippi River Delta and Gulf Coast restoration – Environmental Defense Fund, National Wildlife Federation, National Audubon Society and the Lake Pontchartrain Basin Foundation – issued the following statement in advance of Tuesday’s proceedings:
“Nearly five years after the oil disaster, the people and wildlife of the Gulf Coast still wait for justice. For 87 days, BP dumped more than 200 million gallons of oil into our Gulf, contaminating our marshes and beaches and jeopardizing wildlife ranging from brown pelicans to sperm whales. But the oil giant has yet to take full responsibility. BP has dragged out litigation in the courts, challenging every decision only to have each decision against them confirmed by higher courts.
“Despite claims that it would ‘make it right’ in the Gulf, BP has, for the past five years, waged a public relations war focused on blaming everyone else and denying sound scientific research showing ongoing impacts from the oil disaster. The effects of the oil spill are far from over and may not be fully known for years, or even decades, to come.
“Now the court has the opportunity and responsibility to make it right, to hold BP fully accountable for the damage done to the Gulf and to assign the maximum penalty to BP for its gross negligence. The outcome from this decision must send a clear and powerful signal to every other operator in the Gulf: deep-sea drilling is risky business, and they must protect their employees, our communities and our ecosystems. BP chose not to do that, so they deserve to pay the maximum fines allowed by law.
“Through the RESTORE Act of 2012, Congress paved the way for the Gulf’s recovery by ensuring that 80 percent of the Clean Water Act fines BP will pay will be reinvested into Gulf Coast restoration. But that restoration can’t begin until this case is resolved and the legal wrangling ends – and BP remains the principle barrier to much-needed funding going to vital restoration projects.
“Holding BP fully accountable for the 2010 Gulf oil disaster is the fair and right thing to do for the Gulf’s ecosystems and economies. We are hoping, after five long years, that justice is close. The Gulf has waited long enough.”

Since the BP oil disaster began nearly five years ago, ongoing findings deliver truths omitted by BP’s ads: the oil disaster’s negative effects are increasingly clear, present and far from resolved. Over the past year alone, new research has surfaced:
- An October 2014 study showed that the Gulf oil disaster left an “oily bathtub ring” the size of Rhode Island on the sea floor.
- A study by the National Oceanic and Atmospheric Administration (NOAA) detailed how exposure to BP oil can lead to abnormalities including irregular heartbeats and heart attacks in Atlantic bluefin tuna and amberjack.
- A NOAA study revealed that dolphins exposed to BP oil had increased health problems, including adrenal problems, severe lung disease and reproductive issues.
- A study in the Proceedings of the National Academy of Sciences definitively linked a community of damaged deep water corals near the Macondo well to the BP oil spill.
- A Louisiana State University researcher found that the BP oil spill is still killing Louisiana coastal insects.
- Visible tar balls and tar mats continue to surface, including a 40,000-pound tar mat discovered off the coast of a Louisiana barrier island in June 2013, three years after the start of the oil spill.

“Oysters are the most tender and delicate of all seafoods. They stay in bed all day and night. They never work or take exercise, are stupendous drinkers, and wait for their meals to come to them.” – Hector Bolitho
Oysters are remarkable organisms. Not only are they delicious, but each oyster can filter up to 50 gallons of water per day, which provides food for the oyster and improves local water quality. A collection of oysters form an oyster reef, which can provide food and habitat for a wide variety of fish and birds. In addition to these benefits, oyster reefs can also be an important tool for coastal restoration.
Oyster barrier reef restoration can reduce the erosion and retreat of nearby shorelines. An alternative to rocks in some areas of coastal Louisiana, oyster reef restoration can be a low maintenance project, as reefs can build themselves vertically over time, helping them keep pace with rising sea levels.
The benefits of oyster reef restoration can be great, but are all those benefits present as soon as the reef restoration project is finished or do they develop over time? A study published this year in Ecological Engineering, “Temporal variation in development of ecosystem services from oyster reef restoration,” examines the development of oyster reef benefits over time, including improved water quality, stabilization of nearby shorelines and use as fish and bird habitat.
In the study, led by Megan La Peyre, researchers built six experimental oyster reef projects along the shoreline of Sister Lake in Terrebonne Parish, La. The oyster reefs were created using shell material. The researchers found that:
- Reefs were populated by oysters and other filter feeding organisms that provided water filtration benefits within the first year of post-project construction and continued for the duration of the study.
- Shoreline stabilization benefits provided by the restored reef to nearby marshes varied with results suggesting that shoreline stabilization benefits only occurred during periods of high winds and more powerful waves.
- Created oyster reefs immediately provided habitat and had increases in the abundance of fish species associated with them. This remained consistent throughout the study.
The results of this study suggest that oyster restoration projects can provide multiple benefits to the ecosystem that surrounds them fairly quickly after their construction, but that their ability to stabilize nearby shorelines may be limited in areas where waves are small but persistent. However, the researchers in the study suggest that modifications to the design and footprint of oyster reef restoration projects exposed to low energy wave may increase the shoreline stabilization benefits and should be explored further.
Oyster barrier reef restoration projects are an important component in our arsenal of coastal restoration tools. Prominently featured in Louisiana’s 2012 Coastal Master Plan, this project type can have multiple benefits under the right conditions. However, like all types of restoration projects, there are factors that can limit project success. Oyster reef restoration projects depend on the recruitment and survival of oysters, which flourish under very specific conditions. Water that is too cold, too fresh, too salty or doesn’t have enough oxygen can limit the success of the project – if not dooming it to complete failure.
No one type of restoration project is the cure-all for combatting the rapid loss of land in coastal Louisiana. Instead, we need to use a combination of science-based projects in our restoration toolbox to staunch the rapid loss of our coast and build a more sustainable future.No Comments

Allied Concrete Company, a 68-year-old firm based in Charlottesville, Va., is creating new business opportunities by partnering with conservation groups to deploy miles of new oyster reefs along the Gulf Coast. These reefs are composed of an innovative concrete product and create both a restored ecosystem habitat as well as a new business opportunity for Allied Concrete.
In 2011, the 100-1000 Coalition began implementing a project to build 100 miles of oyster reefs in Alabama, which would then support more than 1,000 acres of marshland. Coalition member organizations include Mobile Baykeeper, The Nature Conservancy, The Alabama Coastal Foundation, Weeks Bay Foundation, Dauphin Island Sea Lab, The Ocean Foundation, Alabama Wildlife Foundation and Coastal Conservation Association.
A displaced Louisianan, Allied Concrete company president Gus Lorber has a passion for saving the Gulf. “I grew up in Louisiana and worked, played and fished in the Louisiana and Mississippi Gulf Coast area my entire life,” said Lorber. “I have seen firsthand the degradation of the coastal wetlands in that area my entire life.”
Founded in 1945, Allied traditionally made concrete blocks, but the company has since diversified its product range in response to ever-changing markets and customer needs. Notably, in 2007, Allied joined forces with The Nature Conservancy and others to develop a solution to the declining oyster populations in coastal regions. The result of this partnership was the Oyster Castle, which is a concrete unit by Allied specially designed to build oyster reefs. The unit is made of a “certified blend of proprietary material conducive to attracting and fostering oyster settlement, attachment, and growth.”
Significantly, the Oyster Castle has received a gold Cradle to Cradle certification for its environmentally-friendly design. With Gulf Coast restoration projects likely to ramp up in response to potential monies flowing as a result of the Deepwater Horizon Disaster, Allied’s business is expected to increase. “I firmly believe that, as the RESTORE Act monies become available, the monies should be spent on creating economies in the ‘home’ states, and we are prepared to license local manufacturers to make our units to accomplish this goal,” says Lorber.
Allied is proud to be making a product that has a positive impact in the Gulf Coast. “Besides being my passion, all of my employees love what we are doing with Oyster Castles,” said Lorber. “They feel good about this company for helping the environment, they feel good about their part in making a product that plays a part in this, and they always volunteer for whatever hair-brained scheme I come up with to make products that do good things.”
In addition to providing habitat, oyster reef restoration projects provide numerous environmental benefits including water filtration, habitat for other marine life, storm surge attenuation and erosion control.No Comments
Gulf Tourism Depends on a Healthy Gulf
New report shows wildlife tourism is central to Gulf Coast economy
(New Orleans—July 9, 2013) The coastal environment of the Gulf of Mexico supports a $19 billion annual wildlife tourism industry that is highly dependent on critical investments in coastal environmental restoration, according to a survey released today by Datu Research LLC.
“Wildlife Tourism and the Gulf Coast Economy” concludes that wildlife tourism is extremely valuable to the Gulf Coast economy and relies heavily on the health of the endangered Gulf Coast ecosystem in the five states of Louisiana, Florida, Texas, Alabama and Mississippi. Wildlife tourism includes recreational fishing, hunting and wildlife watching.
Key findings of the report show that wildlife tourism:
- Generates more than $19 billion in annual spending.
- Attracts 20 million participants annually across the five Gulf Coast states.
- Delivers $5.3 billion annually in federal, state and tax revenues.
The study also found tourism jobs can account for 20-36 percent of all private jobs in coastal counties and parishes that are particularly dependent on wildlife activities. Those 53 counties and parishes have more than 25,000 tourism-related businesses and nearly 500,000 associated jobs.
The study reported that all forms of tourism generate 2.6 million jobs in the Gulf states, nearly five times the number of jobs provided by the region’s other three largest resource-based industries: commercial fishing, oil and gas, and shipping.
“With so many outdoor adventure opportunities, tourism is a critical industry to our coastal parishes,” Louisiana Lt. Gov. Jay Dardenne said. “Sportsman’s Paradise is more than our state’s nickname. If Louisiana is to remain the Sportsman’s Paradise, we have to ensure that funds Louisiana receives as a result of the Deepwater Horizon spill are properly and wisely spent preserving our paradise.”
Lt. Gov. Dardenne will speak at a press conference Tuesday, July 9 in New Orleans along with Billy Nungesser, president, Plaquemines Parish; Charlotte Randolph, president, Lafourche Parish; John F. Young, Jr., president, Jefferson Parish; Capt. Ryan Lambert, owner, Cajun Fishing Adventures; Mark Romig, president, New Orleans Tourism Marketing Corporation; Alon Shaya, executive chef, Domenica, Besh Restaurant Group; and Marcy Lowe, president, Datu Research LLC.
The study’s findings underscore the direct connection between the health of the ecosystem and the economic health of the Gulf region and the urgency for using the pending influx of monies from the RESTORE Act and other payments resulting from the 2010 Deepwater Horizon oil spill to properly and effectively restore the fragile Gulf Coast ecosystems.
“The conservation solutions that last are the ones that make economic sense and consider the needs of local communities,” said Scott Burns, director of the environment program at the Walton Family Foundation, which helped fund the survey. “This study connects the dots between a healthy Gulf environment, abundant wildlife and the good jobs that depend on tourism. This report adds to the growing evidence that investing in real restoration in the Gulf is the best way to create jobs and build economic prosperity across the region.”
Datu Research LLC is an economic research firm whose principals were part of the Duke University Center on Globalization, Governance & Competitiveness. They have previously released three analyses of supply chains associated with the work of coastal restoration, showing that more than 400 businesses in 36 states would benefit from such work.
Part II: Supporting comments
Comments from participants in release of study: Wildlife Tourism and the Gulf Coast Economy
John Young, president, Jefferson Parish: “This study further supports the direct link between a healthy coastal environment and a robust economy which depends on a $19 billion wildlife tourism industry. The well-being and continued growth of our coastal communities depend on the health of the Gulf, restoring and strengthening our fragile ecosystems, and promoting a wildlife tourism industry which can thrive, not only in Jefferson Parish but in all Gulf Coast states.”
Billy Nungesser, president, Plaquemines Parish: “Plaquemines Parish and Louisiana are the nation’s premier delta coastline. We are strategically positioned as the fishing capital of the world, the sportsmen’s paradise state and the seafood capital of the United States, and these factors which make Plaquemines and Louisiana unique depend on the health of our coast.”
Michael Hecht, president & CEO, Greater New Orleans, Inc.: “Tourism overall, including wildlife tourism, provides 2.6 million jobs across the Gulf States – and many of these are with small businesses. To protect this vital economic base, as well as other important coastal industries, we must prioritize large-scale coastal restoration projects that will ensure a stable coast and healthy environment.”
Mark Romig, president, New Orleans Tourism Marketing Corporation: “New Orleans attracts the experiential discover type of tourist, one who enjoys using the city as a base to go out and explore any authentic and unique aspects of the city and region, including the natural world. For the many businesses in this region, the need to restore and preserve our coastal wetlands is not optional; it’s an urgent economic necessity.”
Capt. Ryan Lambert, owner, Cajun Fishing Adventures: “I’ve grown up loving and making a living from the waters of the Louisiana coast and for more than 30 years, my business has been taking people fishing in those waters. But every year, as I see places disappearing from the map, I fear I may be part of the last generation to live off the water.”
Ralph Brennan, president, Ralph Brennan Restaurant Group: “Family restaurants like mine depend on a healthy Gulf Coast for the fresh seafood that has made New Orleans the culinary capital of the United States. The money states are beginning to receive to repair the damages from the Deepwater Horizon spill are our best – and may be our last real chance – to reverse decades of mistakes.”
Marcy Lowe, president, Datu Research LLC.: “This study shows the vital connection between the health of the ecosystem and the economic health of the Gulf region. Wildlife tourism is a major contributor to the Gulf Coast economy, but it’s very survival depends on the restoration of an endangered and irreplaceable ecosystem.”
Part III: Key study findings
Report: Wildlife Tourism and the Gulf Coast Economy
Key findings for the Gulf region
“Wildlife Tourism and the Gulf Coast Economy,” a survey produced by Datu Research LLC, finds that in the five Gulf Coast states:
- Tourism generates 2.6 million jobs, nearly five times the number of jobs created by the region’s other three largest resource-based industries combined: commercial fishing, oil and gas, and shipping.
- In Gulf Coast coastal counties and parishes where economies are particularly dependent on tourism, 20-36 percent of all private sector employment is tourism-related.
- Wildlife tourism, which includes wildlife watching, recreational fishing and hunting, generates more than $19 billion in annual spending.
- Wildlife tourism generates $5.3 billion annually in federal, state and local tax revenues, divided roughly equally between local and state tax revenues and federal revenues. In 2011, Gulf Coast state and local governments received $2.5 billion and the federal government $2.8 billion from wildlife tourism. Recreational fishing generates the highest amount of tax revenue at $2.2 billion followed by $2 billion from wildlife watching and $1.2 billion from hunting.
- Wildlife tourism attracts 20 million participants annually across the five Gulf Coast states. The wildlife tourism industry consists not only of wildlife guide businesses that directly serve wildlife tourists, but also the lodging and dining establishments where they eat and sleep.
- Gulf Coast tourism – and wildlife tourism in particular – is highly dependent on a healthy coastal environment.
- More than 11,000 lodging and dining establishments and 1,100 guide and outfitters businesses create business networks that depend on each other for referrals. In a survey of over 500 guide and outfitter businesses, about 40 percent of respondents said clients ask them for hotel recommendations and 55 percent said clients request restaurant recommendations. Likewise, more than 60 percent of guide businesses receive clients based on recommendations from hotels and restaurants.
- Guide and outfitting operations represent a strong network of small businesses that have a large impact on local tourism. More than 86 percent of these businesses have one to five employees, and nearly 60 percent host more than 200 visitors per year, with many hosting several thousand.

Dead zone. Words that bring images of military exercises or deserted, war-torn areas of land, but certainly not an acceptable description of a region that contains some of the nation’s most vibrant and diverse ecosystems, wildlife and habitats. Right?
Recent studies released by the National Oceanic and Atmospheric Administration (NOAA) and conducted by Louisiana State University, Louisiana Universities Marine Consortium, and University of Michigan scientists forecast a “record-setting dead zone” for the Gulf of Mexico this summer. The studies suggest that the 2013 dead zone area could be anywhere between 7,286 and 8,561 square miles, which would be substantially larger than last year’s dead zone of almost 2,900 square miles.
According to NOAA, dead zones are not uncommon for waterways and estuaries, as they have recorded 166 dead zones along United States coastlines. As the Gulf of Mexico is at the receiving end of the country’s largest river system, the Mississippi River’s discharge is one of the main causes of the Gulf dead zone. Unfortunately, a dead zone is exactly what it sounds like: an area normally teeming with wildlife and vegetation is infiltrated by pollutants, fertilizer chemicals and industrial runoff. When the river’s more buoyant fresh water enters the Gulf of Mexico, it lies on top of the denser, saltier water, causing a stratification that isolates the deeper waters from receiving a necessary amount of oxygen.
The Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) explains that the influx of these unnatural substances and nutrients results in the overgrowth of algae and marine organisms on the surface of the water. At the end of their life cycle, they sink to the bottom and are decomposed by bacteria, a process that depletes the oxygen supply from the water, making the existence of life nearly impossible. Every type of marine life is affected, from Gulf fish to tiny marine organisms, which are all essential parts of an interdependent ecosystem necessary for maintaining the balance of life in the Gulf of Mexico.
In scientific terms, the low oxygen is known as hypoxia and has severe effects on the future health and growth of ecosystems. TIME Magazine recently reported that the Gulf of Mexico may soon become an “aquatic desert” and attributes the problems to recent weather conditions in the Midwest: heavy rainfall and flooding increases the levels of nutrients and pollutants in the river. All of these compounding problems will contribute to the 2013 possibly record-setting dead zone.
Scientists state that the dead zone would be less severe if a tropical storm were to enter the area, which would mix up the Gulf’s waters and facilitate oxygenation. The irony of this fact is that it leaves Louisiana residents in a less-than-ideal situation.

This story was originally posted on the Coalition the Restore Coastal Louisiana's Coastal Currents blog.
By Scott Madere, Coalition to Restore Coastal Louisiana
Our coastal wetlands have immeasurable worth to Louisiana in terms of culture. Our history, art, celebrations, recreational opportunities and so much more are tied to the muddy waters and vast green expanse of our swamps, forests and coastal marsh. Our love for our land defines us as a people, and we often cite it to those who are not from here as the main reason why Louisiana’s coast is worth saving. It seems natural for us to talk about the coast this way, but to those outside of Louisiana it may be a little hard to understand. That’s why it’s also valuable to be able to talk about Louisiana’s worth in another way: raw dollars, the sheer economic value that the Mississippi River Delta provides to the nation.
Understanding the massive dollar value of what Louisiana provides to the country helps us make the case to our fellow Americans that Louisiana is worth the resources sent here to restore our wetlands. In a political environment where budgets are tight and decisions are made based on investment return, this could potentially be Louisiana’s best angle toward building more national support for restoration.
So let’s explore it. The Mississippi River Delta Science and Engineering Special Team (SEST), made up of 22 of our nation’s best coastal scientists and engineers, published a report in 2012: “Answering 10 Fundamental Questions About the Mississippi River Delta.” Within the report, SEST compiled some convincing data about the economic value of Louisiana’s coast from a number of sources. Here are some of the highlights:
- Mississippi River Delta ecosystems provide economically valuable services to the people of our state such as storm protection, fresh water, food, habitat, waste treatment and other benefits. These annual benefits alone are worth up to $47 billion per year to our citizens. With these annual benefits taken into consideration, the present value of the Delta’s ecosystem services could range as high as $1.3 trillion.
- Between 80 and 90 percent of Louisiana’s economy, seafood production and quality of life is linked to coastal ecosystem goods and services.
- Commercial fisheries have a yearly impact of $2.85 billion.
- Recreational fishing generates $1.7 billion annually.
- Economic activity linked to wildlife (hunting, wildlife watching, trapping, etc.) exceeds $1.6 billion each year.
- Tourism generates as much as $10 billion every year for Louisiana.
- The deepwater ports along the Mississippi River from Baton Rouge to New Orleans collectively form the largest tonnage port in the Western Hemisphere. Waterborne commerce in this corridor generates $35 billion annually and as many as 300,000 jobs.
And we haven’t even mentioned oil and gas yet.
According to the Louisiana Oil & Gas Association:
- Our state is the nation’s number one producer of crude oil and the number two producer of natural gas among the 50 states.
- Approximately 80 percent of the nation’s offshore oil and gas resources come from or through Louisiana. That equates to 30 percent of the nation’s energy consumption.
- The Louisiana oil and gas industry exceeds $70 billion of economic impact annually.
After reviewing this very short list of economic benefit provided to us by the coast, it is easy to see two undeniable facts.
First, Louisiana’s coast is an economic engine that needs to be protected. In a time when so much national focus is set on employment numbers, Louisiana contributes positively by providing hundreds of thousands of jobs related to the coast. Even more jobs can be provided by the coastal restoration process itself.
Secondly, placing a national priority on Louisiana coastal restoration is a wise move. The 2012 Louisiana Coastal Master Plan sets a cost of $50 billion to fund its 50-year coordinated coastal restoration strategy. When compared to the potential economic output of Louisiana for the next 50 years, that $50 billion price tag actually seems small.
In the years ahead, Louisiana’s citizens will have to continue to make the case, both on Capitol Hill and in Baton Rouge, that coastal restoration is a top national priority. The numbers do add up when it comes to supporting that claim, and our leaders and citizens should feel confident in taking that position when seeking support from others around the country.No Comments

It’s been an exciting year for Louisiana and the Mississippi River Delta Restoration Campaign.
In July 2011, nine gulf senators banded together and introduced the RESTORE Act – legislation that would ensure penalties paid by BP and others responsible for the gulf oil spill would be used to restore the gulf region’s environment and economy. In September, the Senate Environment and Public Works Committee approved the bill and in October, Representative Steve Scalise (R-LA) and 20 other gulf representatives introduced the House version of the bill. Supporters worked hard and waited patiently as the RESTORE Act continued winding its way through congressional hearings and historic votes until finally, on June 29, 2012, the RESTORE Act was included as part of the final transportation bill and days later signed into law by the President. It was an amazing journey from start to finish, and we want to take a moment to reflect on the past year and begin looking forward to how the RESTORE Act will unfold to become the single largest environmental restoration investment ever made by Congress.
The idea of spending penalty money from the oil spill on environmental and economic restoration in the gulf region is only fair. Diverse groups, including conservation organizations, the Secretary of the Navy, chambers of commerce from across the gulf region and even a special commission created by the President in response to the spill, all agreed it was the right thing to do. Heeding this call, Congress came together to design a bill to return the money where it belongs: to the Gulf Coast. In the Senate, the RESTORE Act received 76 votes – a remarkable display of bipartisanship which highlights the broad support had by the bill. Of course, it could not have happened without our campaign’s supporters, who used social media, letters to the editor and appeals to their congressional representatives to make the bill a top priority.
Looking forward, we are excited that the RESTORE Act has the potential to make the environment and economies of the Gulf Coast healthy again. The RESTORE Act includes a list of various eligible activities that states may use funds for, ranging from coastal restoration and shoreline protection to seafood and tourism promotion. All of these activities will provide new job opportunities for residents along the Gulf Coast and across the nation. As a recent Duke University report shows, the RESTORE Act is a win for the entire country.
The RESTORE Act also sets up a Restoration Council comprised of various federal agencies and states affected by the spill to create an environmental restoration plan for the Mississippi River Delta and Gulf Coast. The plan has the potential to address major, and very expensive, challenges in the Mississippi River Delta. A top funding priority in the plan for Louisiana will be designing and constructing large-scale sediment diversions along the lower Mississippi River. Sediment diversions provide wetlands with essential supplies of fresh water and new silt which help rebuild land and protect the coast.
Over the next few months, the Mississippi River Delta Restoration Campaign will update readers on important RESTORE Act developments. We hope to provide you with useful information as the Restoration Council forms and begins the important process of creating a restoration plan for America’s Gulf Coast.
