Louisiana Plant Materials Center Helps Stop Coastal Erosion

The United States Department of Agriculture runs the Louisiana Plant Materials Center in Galliano, Louisiana next to the airport. The Plant Materials Center plays an important role in coastal protection projects because they are assigned the task of finding suitable plants to use in areas where marshland is being rebuild or protected. The Center is very important to those working on coastal wetland projects, but largely unknown to the public. It is on 90 acres with greenhouses and fields to simulate marsh. The Center can test plants for many years before using them in coastal protection projects.

Dr. Richard Neill, the Center's manager and Garrett Thomassie, the assistant manager, are evaluating the plants that nature has given us and trying to determine which ones create the greatest soil stabilization in various environments. Some of the projects that they have worked on include projects for the Barataria-Terrebonne National Estuary Program, Port Fourchon, re-vegetation of City Park in New Orleans, and re-vegetation of the Naval Air Station at Belle Chase.

If you are interested in learning more about the Louisiana Plant Materials Program, you can arrange a tour by calling (985) 475-5280. Also see, the Saturday June 21, 2008 article at WWL-TV entitled, Plant Center grows plants that halt coastal erosion.

Recent Studies Suggest Seas Rising and Warming Faster than Previously Realized

Andrew C Revkin writing for the New York Times describes a variety of recent research suggesting that the worldwide sea level rise is greater and faster than previously realized. His recent article was published on June 19, 2008 in the Dot Earth blog and is entitled: Seas Rising and Warming Faster than Realized. He has linked his article to a number of other interesting and relevant publications.

The worldwide sea level rise is a very important aspect of coastal land loss in Louisiana. This is a global condition overlaying a problem associated with the management of the Mississippi River system that cannot be ignored. Global sea level rise further demonstrates the urgency with which action is needed in Louisiana on coastal land building.

Resolution Passed Calling for 8/29 Commission

Mark Schleifstein of the New Orleans Times-Picayune writing on June 19, 2008 in an article entitled, Levee authority backs national '8/29 Commission' investigation reported that the Southeast Louisiana Flood Protection Authority had passed a resolution asking Congress to create a 8/29 Commission to investigate the government's handling of the aftermath of Hurricane Katrina. The resolution was proposed by John Barry, the author of Rising Tide.

Barry stated,

"I'm really asking that they take a comprehensive look at the entire Mississippi River system, the entire Mississippi valley, from New York state to Idaho," Barry said. "They should look, for instance, at the dams on the upper Missouri River in detail, because they have a real impact on the amount of sediment that's carried in the river, which has a real impact on the erosion of wetlands in Louisiana."

"If the nation understood the reality of the negative impacts on us in the metropolitan area of economic decisions upstream that were made in the national interest," it might lead to better decisions in flood control involving both protection from hurricanes and high rivers."

John Barry has said it exactly right. I am not aware of anyone speaking more closely to my own thinking on the causes and solutions related to the loss of Louisiana's coastal wetlands than John Barry. The idea of a 8/29 Commission is an excellent one. The scope he suggests addresses exactly the issues that I have been raising in this blog. The loss of coastal wetlands in Louisiana is a national problem caused by the management of the Mississippi River drainage basin by the federal government. 

I am not suggesting the federal government should not manage the Mississippi River drainage basin. I am just urging the federal government to acknowledge and take responsibility for their predominant role in causing coastal land loss in Louisiana.

National Research Council Publishes First Report on Corps' Louisiana Coastal Protection and Restoration Technical Report

The National Academies Press has published its First Report from the NRC Committee on the Review of the Louisiana Coastal Protection and Restoration Program. The NRC is the National Research Council which group acts as the official scientific adviser to the federal government. 

The report is available for free download as a .pdf file from the National Academies web site. This is an important report worth reading. This report is a response to the Corps' March 2008 report entitled, "Louisiana Coastal Protection and Restoration Technical Report." In turn, the Corps' report was a response to a request from Congress for a category 5 hurricane protection plan for South Louisiana.

The Corps' report commendably speaks to the need to preserve and restore Louisiana's coastal wetlands in order to provide hurricane protection for the region. Nevertheless, one of the NRC committee's leading complaints about the Corps' plan is that it relies upon "sustaining the existing landscape" and yet the Corps has provided no evidence that it is possible to sustain the existing landscape. In this regard, the NRC committee complains that the Corps has not done the basic analysis of sediment available in the Mississippi River for a determination of what portion of the coastal wetlands in Louisiana can be sustained. If insufficient sediment exists in the Mississippi River water flow to sustain the existing coastal environment then the Corps' entire report is ill conceived.

If the sediment budget in the river is insufficient to sustain the existing coastal environment, the Corps and others will have to make some difficult decisions about what parts of the coastal landscape can be saved and what will not be saved. The Corps has not addressed this issue.

This missing analysis takes us to the core of the problem that I have written about in this blog since its outset. The most fundamental cause of coastal wetland loss in Louisiana, particularly south of New Orleans where below a certain point there are no levees, is lack of sediment in the Mississippi River water flow as the result of dams and reservoirs as well as locks and slack water pools in the northern parts of the Mississippi River drainage basin. These river structures reduce the sediment load in the river.

A reduced sediment load in the river is good for navigation and bad for coastal wetland building. The Corps must deal with a conflict between those competing interests. The Corps operating north of Louisiana wants a river with a reduced sediment load because that river condition makes it easier to maintain a navigation channel of a set depth. Less sediment in the river flow means less dredging of the navigation channel for the Corps.

The Corps in Louisiana has the same concern with navigation, but also has a need for sediment load for use in coastal wetland restoration and preservation. Those interests compete with one another to some extent. Unfortunately, coastal wetland protection and restoration in Louisiana does not get much, if any, consideration when the Corps makes a decision north of Louisiana adversely impacting on sediment load in the Mississippi River that will ultimately reach Louisiana. The interests of navigation prevail in such considerations north of Louisiana and most of those considerations within Louisiana.

The Corps needs to make a careful examination of the Mississippi River sediment load as it relates to proposed coastal wetland restoration and preservation projects. The Corps also needs to begin considering sediment load as it relates to Louisiana's coastal restoration and protection needs when it makes decisions along the entire course of the Mississippi River drainage system. Until this analysis is done and this consideration is given, no one will know what can really be done to preserve and restore Louisiana's coastal wetlands.

The current approach is to view coastal wetland preservation and restoration in Louisiana as a matter of regional decision making in relation to management of the Mississippi River in Louisiana. In reality, In reality, the preservation and restoration of Louisiana's coastal wetlands requires considered decision making across the entire Mississippi River drainage basin covering much of the continental United States.

Ducks Unlimited Names New Government Affairs Director

Ducks Unlimited is a friend to the movement for the restoration of Louisiana's coastal wetlands. Bob Drew, the manager of conservation programs for Ducks Unlimited has properly stated that state and federal agencies are the only ones that have the capacity to implement large scale coastal restoration programs which Ducks Unlimited supports.

For this reason among others, Ducks Unlimited announced the appointment of Jennifer Grand as the Louisiana government affairs director for Ducks Unlimited. Grand is based out of their Lafayette office. For more information on the appointment of Ms Grand, see the April 10, 2008 article in the Lafayette Advertiser entitled: Wetlands warrior: Conservation organization creates post.

Mississippi River Sediment- The Corps' Conflict of Interest

As I have written many times before, the principal cause of coastal wetland loss is the reduction of sediment load in the Mississippi River. The reduction in sediment load has been caused primarily by the construction of locks and dams in the Mississippi River drainage basin, and the dams in the Missouri and Arkansas River systems are the most significant.

For the Corps of Engineers representatives working north of Louisiana, the reduction in the sediment load is a good thing. If your primary concern is navigation in the river system, a river with little sediment load is a good river. It means the Corps does not have to dredge the river bed as much.

In contrast for the Corps of Engineers in New Orleans tasked with coastal wetland restoration, a river with a limited sediment load makes their restoration job harder. Of course, the Corps in New Orleans is also given the task of maintaining navigation on the Southern course of the river. Thus, the Corps in New Orleans also prefers the smallest possible sediment load for management of their navigation responsibilities.

Which objective does the Corps serve? How do they decide which objective to serve and when? As far as I can determine, the Corps gives no consideration to the sediment load in the Mississippi River system needed for restoration and preservation of Louisiana's coastal wetlands when the Corps makes decisions about river management north of Louisiana. As a practical matter, the Corps cannot serve both objectives with no oversight and be expected to preserve and restore Louisiana's coast. The navigation interest extends for most of the river system course and the focus on preservation and restoration of coastal wetlands is an active part of decision making only in the Southernmost section of the river. Preservation and restoration of coastal wetlands loses and navigation wins in that internal competition at the Corps. As a practical matter, it cannot be any other way. 

The responsibilities for decision making need to be split and a neutral third party needs to be responsible for balancing the two interests.

A good recent news article expressing concern with the negative impact of sediment load on navigation can be found in the Baton Rouge Advocate on April 12, 2008. The article was written by John A Colvin and is entitled, Mississippi River sediment piling up.

Lost Opportunity - High Water on the Mississippi and Coastal Wetlands

As the Corps of Engineers closes gates on the Bonnet Care spillway and the water level on the Mississippi River goes down, Louisiana has lost a once in a decade opportunity to divert an enormous amount of river sediment into the coastal wetlands of Louisiana. Times of high water on the Mississippi River are very important times in the coastal wetlands land building process. Unfortunately, we were not prepared to take advantage of this rare opportunity and the loss of coastal wetlands continues.

According to Chris Kirkham's Friday April 18, 2008 article in the New Orleans Times Picayune entitled, State may be spilling coast's rescue, the recent high water event on the Mississippi River brought 900,000 tons of river sediment through the state and into the Gulf of Mexico.

If the Corps of Engineers had been better prepared to divert a large portion of the sediment into the coastal wetlands, the condition of the coastal wetlands might have improved this spring. The Corps of Engineers needs to change the river management to take advantage of the next high water level event.

Corps Faces Trial in MRGO Suit

I have long contended that the federal government is subject to suit in tort for the damage that they have caused to Louisiana's coastal wetlands. United States Federal District Court Judge Stanwood Duval entered a ruling on Friday May 2, 2008 supporting this position.

On Friday, Judge Duval held that the United States Army Corps of Engineers is subject to suit for alleged defects in the Mississippi River Gulf Outlet ("MRGO") that destroyed wetlands and are alleged to have turned MRGO into a funnel for hurricane storm surge. MRGO is a navigational canal build and operated by the Corps connecting the Gulf of Mexico to the Inner Harbor Navigation Canal also known as the Industrial Canal in New Orelans via the Gulf Intracoastal Waterway.

Judge Duval rejected the Corps' claim that federal law makes the agency immune from lawsuits over damage caused by its flood protection projects. The judge found that because the navigational channel is not part of the Lake Pontchartrain and Vicinity Hurricane Protection Plan, the Corps is not immune from suit.

The ruling on Friday is not a final decision in the case. It does not find that the Corps is liable for damages caused from flooding in East New Orleans, the 9th Ward and St. Bernard Parish. This determination will only be made at the conclusion of the trial.

For a more detailed account of the decision, see Susan Finch's article in the New Orleans Times Picayune entitled: Judge: Corps can be sued for flood.  

If ultimately upheld, this decision would support other tort suits against the federal government and the Corps of Engineers related to damage that the Corps has caused to Louisiana's coastal wetlands.

John Barry States Federal Government Should Pay for Coastal Protection and Restoration in Louisiana

John Barry, the author of Rising Tide, has published an Op-Ed piece in the Los Angeles Times on Wednesday April 23, 2008 entitled: Who Should Pay to Protect New Orleans. I have never seen the cause of the coastal land loss problem described more succinctly or the solution described more accurately.

Barry points out what I have been saying less artfully for many years. The most fundamental reason that the coastal wetlands in Louisiana has been lost, particularly below New Orleans, is the reduction in the sediment load in the Mississippi River drainage system. This reduction has resulted from the construction of dams in the tributaries with particular emphasis on the dams built in the Missouri River in North and South Dakota. The lower portion of Louisiana's "bird's foot" did not erode to open water because of levees in Louisiana. Below a point, no levees separate the wetlands from the river and yet the land continues to dissolve into the Gulf. The problem is not the result of a local action.  

Louisiana derives no direct benefit from those Corps dams in the Dakota's and Montana. They were built to control flooding and improve navigation on the Missouri River. In fact, the Corps of Engineers claims that it has no authority to manage the Missouri River system and those dams for the benefit of the Mississippi River or its users in any way. The Mississippi River is treated as disconnected and unrelated to the Missouri River for all purposes that the Corps of Engineers considers.

John Barry is exactly right when he says the coastal land loss problem in Louisiana has been caused as the result of actions that benefited other parts of the nation far removed from Louisiana. The protection and restoration of coastal Louisiana is a national problem requiring federal action.

Jindal Asks Corps of Engineers to Change Organization Structure

Louisiana Governor, Bobby Jindal, has asked the Army Corps of Engineers to change its organizational structure. Jindal wants the New Orleans District Office of the Corps to be come a Division Office reporting directly to the Corps headquarters in Washington.

At present, the New Orleans District Office of the Corps reports to the Division office in Vicksburg, Mississippi. This change would reduce the time required for the Corps to make decisions related to New Orleans and Louisiana coastal protection and restoration.

Garrett Graves, Governor Jindal's Director of the Office of Coastal Activities, made the formal request to the Mississippi River Commission in Vicksburg. Graves stated that the change was crucial now because the Corps was preparing to undertake $15 billion in repair and rebuilding of the region's hurricane protection flood system.

For more information on this request, se the New Orleans Times Picayune articled from Saturday April 12, 2008 entitled: Jindal seeks change in Corps of Engineers organization.

National Academy of Science Peer Review Committee Questions Corps' Coastal Restoration Plans

The National Academy of Sciences has appointed a committee of  the country's top scientists to peer review the coastal protection and restoration plans of the Army Corps of Engineers in Louisiana. The National Academy of Sciences is the scientific adviser to the federal government.

At a meeting on Thursday April 3, 2008, the National Academy peer review committee and the Corps held a public meeting concerning the peer review committee's work. The peer committee was critical of the Corps' plans in a number of respects.

The question being considered at the meeting was whether the Corps plans to protect and restore the Louisiana coast will work. The National Academy scientists began by questioning the Corps basic strategy which is to maintain the coast as it currently exists. The National Academy scientists questioned why the Corps was not considering other alternatives such as creating new land and allowing some areas to erode.

The National Academy scientists also questioned whether the Mississippi River carried enough sediment today to maintain the coast as the Corps suggests that its plan would do.The scientists seemed surprised and upset that the Corps' representatives did not have a basic knowledge of how much sediment the river carried and had not taken steps to determine if the available sediment was sufficient to achieve the Corps' objectives. 

One of the National Academy scientists questioning the Corps was Robert Meade. Meade is retired from the United States Geological Survey. Meade is well known in the scientific community for his knowledge of sediment transport in rivers and particularly in the Mississippi River. The representatives of the Corps might serve themselves well to read some of the scientific articles that Meade has previously published on sediment transport in rivers.  

The question of sediment supply in the Mississippi River is critical to the success of any coastal protection and restoration project in Louisiana. The sediment load in the Mississippi River has declined sharply since the 1930's as a result of the extensive construction of dams and locks in the Mississippi River drainage system. Dams trap sediment in the reservoir behind the dam and the locks trap sediment in the slack water pool behind the lock. The most significant sediment transportation reductions have occurred in the Missouri River and Arkansas River which are tributaries of the Mississippi River.

For navigation purposes, sediment in the Mississippi River is a nuisance that requires dredging. Much of the Corps operations in the Mississippi River drainage system are centered upon navigation. This means that for most purposes north of Louisiana on the Mississippi River and its tributaries, the Corps would like to see as little sediment transport in the river as possible. This desire, however, runs counter to the needs of coastal Louisiana. These navigational needs have in the past and continue today to trump the coastal restoration and protection needs of Louisiana. When the Corps considers how it will build and operate projects north of Louisiana in the Mississippi River drainage basin, the sediment transportation needs of Louisiana's coast are not typically considered.

Congress had asked the Corps to deliver the Louisiana Coastal Protection and Restoration Plan in December 2007. Now the plan will not be delivered until December 2008. Further, Congress had asked the Corps to identify a set of coastal protection and restoration projects that could be started quickly. Instead, the Corps has now stated that its December 2008 plan will not "include the specific identification of a detailed plan." Instead, the Corps' report will include aspects that require additional study before Congress can fund and the Corps can begin construction of the projects ultimately included in the plan.  

The National Academy scientists led by Robert Dalrymple, a civil engineering professor at John Hopkins University also questioned this "further study" approach.  Dalyrmple suggested that Congress might have been trying to create a sense of urgency after Hurricanes Katrina and Rita for more immediate action.   

The National Academy scientists also questioned why the Corps report did not include a major diversion of the Mississippi River south of New Orleans as many scientists and environmental groups have recommended. Instead the Corps report will suggest a number of smaller diversions. 

For a more detailed description of this meeting, see Mark Schleifstein's article in the New Orleans Times Picayune of Saturday April 5, 2008 entitled: Reviewers Grill Corps on Coast Plans

Louisiana Faces Coastal Restoration Funding Challenges

In the next several years, Louisiana faces serious challenges funding the state's share of scheduled hurricane protection and coastal restoration projects. Louisiana's share of such projects scheduled for fiscal year (fy) 2009 is $1.2 billion. While Louisiana's recent special session received significant media coverage in part because of the appropriation of $300 million for hurricane protection and coastal restoration projects, this funding is far short of the money required to cover the state's burden for projects planned by the federal government.

Even when this $300 million additional appropriation is combined with the prior budget of $224 million, the state is still short of the needed funding for fy 2009. In 2010 and beyond, the state's funding challenges continue. Louisiana will need $748 million in 2010 and $642 million in 2011 to cover Louisiana's share of federal led hurricane protection and coastal wetland restoration projects with considerable emphasis in all of these years on hurricane protection projects.

These  projects are indispensable to the future of Louisiana, and the state will have to find new funding sources to cover the costs. Even if all of these scheduled projects are fully funded, the spending proposed for coastal wetland restoration and protection is still far short of the need.

Louisiana is no where near the level of funding needed for a material coastal wetland protection much less a restoration program.  For more information on these funding challenges, see March 19, 2008 Times Picayune article, Coastal Authority to Meet Today to Talk Funding

Shea Penland, Louisiana coastal restoration scientist, dies

The New Orleans Times Picayune is reporting on its web site as of 9:40 PM on Wednesday March 26, 2008 that Patrick "Shea" Penland has died at age 54. The obituary is entitled, Shea Penland, important Louisiana coastal scientist, dies

According to the T-P article,

"Penland was the director of the Pontchartrain Institute for Environmental Sciences at the University of New Orleans. He earned an undergraduate degree in physical geography from Jacksonville University in Florida. He earned master's and doctoral degrees in coastal geomorphology from LSU. Since 1979, Penland has published more than 100 papers for scientific journals, conducted more than 30 field trips and led more than 30 sessions at scientific meetings on the evolution of coastlines."

Although I did not always agree with Penland, he was an important voice in support of the restoration of coastal Louisiana who will be missed. I offer my prayers and condolences to his family at this difficult time.

Southwest Louisiana Seeks Coastal Restoration Aid

The Baton Rouge Advocate published an article on Friday February 29, 2008 entitled, Southwest La. wants coastal aid. This article summarizes recent complaints from public officials in southwest Louisiana concerning the relative balance of limited coastal restoration funds between southeastern and southwestern Louisiana.

These officials complain that in the 2009 Coastal Restoration and Protection Authority (CRPA)budget a total of $14 million in funds are budgeted for southeast Louisiana projects and only $1 million in funds are budgeted for projects in southwest Louisiana.

The chairman of CPRA, Garret Graves, seems prepared to respond. He has indicated in a recent CPRA meeting that the Jindal administration is considering a restructuring of the board to allow more balance. The type of restructuring that is under consideration is using land mass or population to determine representation.

De-Authorization of Mississippi River Gulf Outlet

One cause of coastal land loss in Louisiana is saltwater intrusion into the coastal wetlands. One cause of saltwater intrusion into the coastal wetlands are north-south navigation channels connecting the Gulf of Mexico with inland locations. The construction and subsequent dredging of these open water channels allow saltwater to move inland further than existing wetlands would otherwise permit.

The Mississippi River Gulf Outlet also known as MRGO is one such navigation channel. Along the course of this channel since it was built in the late 1950's, larger and larger bodies of open water at and near the main channel have developed.

After hurricane Katrina, MRGO was referred to as the hurricane highway and blamed for storm surge reaching into St. Bernard and Orleans Parish along the course of MRGO. This resulted in a lawsuit against the Corps of Engineers for resulting flood damage that is still pending in federal court as of this writing.

After the hurricane, the Corps of Engineers began receiving increasing political pressure to close MRGO. This has result in a study and recommendations from the Corps concerning the closure of MRGO. These reports and studies are available on line at the Corps website for the New Orleans district.

National Wildlife Federation Urges Coastal Wetlands Restoration Efforts

On February 29, 2008, the Baton Rouge Advocate newspaper published a letter from Maura Wood, a senior program manager with the National Wildlife Federation, under the headline, Letter: Preventing disasters key issue. Woods indicates that the National Audubon Society and the Environmental Defense Fund also support the efforts of the National Wildlife Federation in this cause.

In this regard, Woods urges representatives of Louisiana in Washington, D.C. to be leaders in restoring coastal wetlands as a barrier protecting the people living in South Louisiana from hurricanes.  Ms. Woods calls for a sense of urgency in the use of the land building power of the Mississippi River to restore coastal wetlands in Louisiana.

It is good to see these national environmental organizations taking a special interest in this important issue.

Chemical to Lure Nutria Out of Coastal Wetlands in Louisiana Found

A team of scientists has identified chemical compounds that can be used as bait to entice nutria into traps. Once in the traps, the nutria can be transported to areas away from the coastal wetlands. Nutria are about ten pounds in size and feed on grasses in coastal wetlands. Nutria are originally from South America, but were introduced to the Louisiana coastal wetlands in the 1930's.

Professor Athula Attygalle, an expert in molecular chemistry and mass-spectrometry based at Stevens Institute of Technology in Hoboken, New Jersey, and a team of scientists from Cornell University and University of Iowa, have found a compound the nutria like which does not damage the environment.

Several volatile compounds, including terpenoids, fatty alcohols, fatty acids and some of their esters, were identified from solvent extracts prepared from anal scent glands of nutria according to the lead researcher.  The researchers believe that these compounds can serve as a powerful attractant to the nutria. While federal agencies have looked at various poisoning methods, none of those efforts has gone very far because of their harmful effects on other species.

An article published on March 10, 2008 concerning these new compounds can be found in the Environmental News Service in an article entitled: Chemical Found to Lure Nutria Out of Louisiana Wetlands.

High Plains States Seeking Missouri River Study

The Bismarck Tribune published an editorial on March 7, 2008 entitled, Missouri River Study Could Be Spendy. The editorial concerns the current effort of certain interests along the Missouri River to have a new study done of the river and its tributaries.

The states along the Missouri River north of Sioux City, Iowa would like to see the Corps of Engineers conduct a new "Section 216 Study" of the Missouri River and its tributaries. In sum, these states would like to see the Corps rethink how it balances the navigational interests in the Missouri River which apply to those along the river south of Sioux City, Iowa against other interests in the river such as recreation, flood control, drinking water uses, irrigation, environmental protection, etc...

Most people in Louisiana probably do not think much about the Missouri River, but historically most of the sediment that built the coastal wetlands of Louisiana came down the Missouri River which enters the Mississippi River just north of St. Louis. After the Corps completed a series of dams in the upper Missouri River, very little sediment continued to flow down the Missouri into the Mississippi River. The old adage about the lower Mississippi River was that the water came from the Ohio River and the mud came from the Missouri River. Hence, the Missouri River's nicknames was the "Big Muddy" and "Dark River,"  and the residents along it used to say the water of the Missouri River was "too thick to drink, too thin to plow."

The people of the upper Missouri River recognize that the volume of barge traffic on the Missouri River has fallen to the point that it is not a significant economic issue any more. Thus, these people north of the navigable section of the Missouri River would like to remove or at least de-emphasize navigation as a factor in deciding how to manage the Missouri River.

This move should be of interest to Louisiana. If the river can be managed in a way that increases sediment load in the river, this could aid Louisiana's efforts to restore the coastal wetlands. The reservoirs behind the large dams on the Missouri River trap sediment, but management techniques and construction techniques exist for flushing sediment through such reservoirs.

The impact that the operation of the Missouri River has on Louisiana should be considered in any new study of the Missouri River. This impact has not been considered in the past and that needs to change.

Oh, nooo! Mr. Bill Supports Louisiana Coastal Wetland Restoration

Mr. Bill, the clay character made famous on Saturday Night Live now appears in public service announcements concerning Louisiana coastal wetland loss. The creator of Mr. Bill is Walter Williams. Williams in a New Orleans native who lived in New York City and Los Angeles from 1976 to 2001. He has now returned to New Orleans and lives in the French Quarter.

Williams is using his clay character to warn the public about the problems associated with coastal wetland loss in Louisiana. He is also making documentary films (without the Mr. Bill character) concerning the natural history of New Orleans and the loss of coastal wetlands in Louisiana.  

A profile of Mr. Williams and his efforts can be found in the USA Today newspaper in an article published on Wednesday March 12, 2008 entitled, La. wetlands hero has feet of clay.

Nutria Damage Coastal Wetlands

The nutria, a rodent found in the coastal wetlands of Louisiana, are known for eating marsh grass and contributing to the loss of coastal wetlands. In recent decades, the nutria have eaten their way through hundreds of square miles of coastal wetlands.

The state of Louisiana began trying to control the nutria population in 2002 by offering a $5 per tail bounty for killing the rodent. The nutria was introduced into the Louisiana wetlands from South America in the 1930's. The 20 nutria brought to Louisiana in the 1930's bred an estimated 20 million animals within two decades.

For many years, this resulted in a profitable fur trade. In the 1960's and 1970's, trappers collected more than 1 million nutria pelts per year. In 1976 alone, trappers collected more than 1.8 million nutria pelts in Louisiana.

In the 1980's and thereafter, fur's popularity declined and the value of a nutria pelt fell from around $10 to about $1. This led to trapper's leaving the business and an explosion in the nutria population. By 2001, the nutria were damaging 81,000 acres a year of wetlands in Louisiana. Since the state bounty was placed on the nutria, the damage has declined to about 34,665 acres in 2007.

For more information on the nutria in Louisiana's wetlands, see the news article in the New Orleans Times Picayune published on February 25, 2008 entitled, Nutria Nation: marsh-eating critter rebounds in post-Katrina.

Jindal Administration Plans Larger Commitment to Coastal Restoration

Garrett Graves, the new director of the Governor's Office of Coastal Affairs announced at a the February 24, 2008 meeting of the Coastal Protection and Restoration Authority that the Jindal administration planned a larger financial commitment from Louisiana for coastal restoration. Graves indicated that Louisiana could stop all other economic development initiatives if it were not prepared to do more to protect and restore the coast.

Graves also indicated that that the state was considering a number of larger scale projects that would be massive diversions from the Mississippi River. These projects include the artificial third delta and a large diversion in lower Plaquemines Parish.

The Jindal administration considers Louisiana under invested in coastal restoration and levee protection and seeks to change this condition. Of course, this change will also require a fundamental change in the way the Corps of Engineers moves forward with projects.

For more information on Graves comments at this meeting, see the Baton Rouge Advocate article published on February 25, 2008 entitled, Official: La to expand coastal commitment.

Louisiana May Struggle To Find Matching Funds for Hurricane Protection

The New Orleans Times Picayune published an editorial on Wednesday March 5, 2008 entitled, Editorial: Promises, not favors.  According to John Barry (author, Rising Tide), a member of the state's Coastal Protection and Restoration Authority (CPRA), the Bush administration has indicated that it was doing Louisiana a favor when it gave Louisiana a year to come up with $1.78 billion in matching funds for levee improvements and flood control projects.

Members of CPRA do not believe that Louisiana can come up with $1.78 billion on such a short time frame, and this problem could jeopardize construction of 100 year flood protection for New Orleans by 2011 as President Bush and the Corps have promised.

Barry urges the federal government to allow Louisiana a 30 year payment plan for providing its share of the cost of the flood protection and levee improvement plan. The size of this project is not typical and the match is outsized justifying the additional time.

The Times Picayune editors rightly point out that President Bush stood in Jackson Square after Hurricane Katrina and promised to do whatever was necessary to rebuild New Orleans. Stronger levees and healthy coastal wetlands are an essential part of rebuilding a thriving New Orleans. President Bush and his administration should live up to this promise.

Boustany seeks coastal protection funding equity for Southwest Louisiana

U.S. Representative Charles Boustany believes Southwest Louisiana is not getting its fair share of funds for coastal restoration. Boustany recently sent a letter to Governor Jindal as well as the leadership of the state house and senate complaining that Southwest Louisiana is shortchanged in money allocation and attention from the Coastal Protection and Restoration Authority (CPRA). Because of this, Boustany would like to change the make up of the CPRA board to allow more representation from Southwest Louisiana. The area of concern to Boustany is from Vermilion Parish to the Texas state line and includes the Chenier Plain.

Expert Says Wetlands Require Urgent Action

The Baton Rouge Advocate published a letter on March 5, 2008 under the headline, Letter: Wetlands require urgent action. Kerry St. Pe, the program director for the Barataria-Terrebonne National Estuary Program, wrote in the Baton Rouge paper that all stakeholders must join together to move quickly to restore coastal Louisiana.

St. Pe concludes that the state cannot afford delays that might be caused by strategies that could result in drawn-out disagreement. He emphasizes the adoption of proven technology on a large scale. In particularly, he suggests using existing sediment delivery technology such as dredges, pumps and pipelines need to be employed immediately. The land built through the sediment delivery processes must then be supported with small to medium size river diversions. These diversion will sustain the new land.  

St. Pe expresses concern about the disagreements arising from large scale river diversions. He views large scale diversions as potentially contentious and questions whether such diversion have long term benefits.

In sum, St. Pe thinks Louisiana should focus on the strategies where consensus exists.

Mississippi River Delta Subsidence Caused by Compaction

On February 17, 2008, Torbjorn E. Tornqvist of Tulane University and other researchers published a letter in the journal Nature Geoscience entitled Mississippi Delta subsidence primarily caused by compaction of Holocene strata. The research findings suggest that the Mississippi delta is sinking as much as one fifth of an inch per year, but that the sinking is mostly limited to the upper layers of sediment while the land beneath is more stable.

This research suggests that the high rate of subsidence is largely the result of compaction of the shallow sediment deposits from the last 10,000 years in the upper few hundred feet near the surface of the earth. These findings suggest that flood control structures that penetrate through the shallow sediment deposits and rest on the more stable foundation below would not subsidence as quickly.

News articles reporting on this research include: Science Daily in an article entitled Post-Katrina Rebuilding? Mississippi Delta Both Spongy and Stable published on February 22, 2008; and New York Times in an article in a section entitled Observatory with the article title Support for a Theory As to Why Land Sinks Along the Gulf Coast by Henry Fountain published on February 19, 2008.
