God of unchangeable power, when you fashioned the world the morning stars sang together and the host of heaven shouted for joy; open our eyes to the wonders of creation and teach us to use all things for good, to the honor of your glorious name; through Jesus Christ our Lord. Amen. (Source: A New Zealand Prayer Book, p. 569)
Before our city and coastlands were flooded by Hurricane Katrina, there was a cry to rebuild wetlands that were disappearing. Before I became a priest, I was involved in the shrimp-boat industry. I had the privilege to befriend Cajun and Vietnamese families that had been fishing for generations. “Saltwater incursion” was a term I learned about very early on. We knew then and did nothing or very little. The voices of a few fishermen echoed in an endless hymn of subsistence, in a void hemmed in by the greed of special interest.
I have also been involved with the offshore industry through various professional positions. My father was a marine surveyor, so I was brought along to shipyard after shipyard during my youthful summers. We were also a multi-generational boating family, so I came to know our coastlands and learned about all the potential bounty it provided.
I can even remember when Cat Island was big, and we’d camp on its peninsula. I remember steaming out to Chandeleur Island when it was an island and not a reef. I remember seeing vast schools of fish in Mississippi Sound and trolling for mackerel, fishing for white trout and watching the pogie boats set out their nets. But as the song says, “It ain’t der no more,” or at least not like it was.
Then I became a priest. Now my experience is filtered through the sacred lens of my faith. That experience includes all things created. If you think for a moment that the bayous, wetlands or offshore islands are not sacred, then you haven’t seen a sunrise in winter in a pond off of Lake Borgne. If you think that our linkage to nature is only a means to our personal ends, then you haven’t read the Gospels.
Somewhere and somehow, we lost our communion with creation. Nature, even our wetlands, became an object to an end – no longer a co-participant in creation and the cosmos, but rather “a resource” to be used without consideration of moral, ethical and even sacred thresholds.
The heart of a faith-based eco-theology stretches back to the very start of Christianity. Indeed, the harshest critic of abusive power and thoughtless human consumption was that little Rabbi Yeshua. He gives us a constant critique of wealth on the altar rather than God and humanity. So it is with eco-theologians. In the 12th century, a nun by the name of Hilda critiqued and catalogued the pollution of the Rhine River and called for a unification and cooperation with nature in her writings. In the early and into the mid 20th century, holy scientists like de Chardin would say:
“The day will come when, after harnessing space, the winds, the tides, and gravitation, we shall harness for God the energies of love. And on that day, for the second time in the history of the world, we shall have discovered fire.”
Later in the 20th century, outspoken voices like Thomas Berry, a scientist-theologian, would seek to reunify nature and the sacred. He would claim that as Christians, our obsession with redemption history is out of sacred context and causes a chasm between God and humanity. He reminds us:
“The naïve assumption that the natural world is there to be possessed and used by humans for their advantage and in an unlimited manner cannot be accepted.”
If the sunrise on the sea and the wind in salt marshes are sacred, then such is also a litany of sacred expression. Just as holy people everywhere are called to care for sacred texts, churches, mosques and synagogues, then too we are called as people of faith to care for the even greater sacred text that is Nature.
So, is there confession of sin in the wetlands? Is there a movement toward reconciliation with creation? Is there a desire to repent and to “sin no more?” I hope so. I pray so. I dream of a day when our wetlands heal and in their health, we find our health.
Tracking Fish with Acoustic Telemetry—Implementation of an Exciting Technology in Lake PontchartrainMay 31, 2016 | Posted by Emily McCalla in Hunting and Fishing, Science, Wildlife
By Nic Dixon, Outreach Associate, Coalition to Restore Coastal Louisiana
The Louisiana Department of Wildlife and Fisheries (LDWF) and many other fisheries organizations and scientists worldwide have traditionally used fish tags to keep track of fish populations. You may have even applied these simple dart-tipped plastic tags to a fish yourself. Standard fish tagging efforts (in part) identify where the fish was originally captured, Point A, and then where the fish was recaptured, Point Z. But there is not a clear picture of where these fish were for points B, C, D, etc.
Now, thanks to an acoustic telemetry project, LDWF has been able to pinpoint the exact locations of 244 speckled trout, 64 redfish and 18 bull sharks in the Lake Pontchartrain area.
What exactly is acoustic telemetry you ask? It’s the ability to track animals at a distance using sound. An acoustic transmitter that emits a pinging sound is surgically implanted into the fish. When the fish swims within a half mile of one of the dozens of stationary receivers scattered around Lake Pontchartrain, it records the transmitter’s ping as time, date and fish ID number. This data is downloaded from all of the receivers every 6-8 weeks, and LDWF publishes their data in an interactive map: the LDWF fish tracker.
This information isn’t just exciting for the intrigued anglers in Lake Pontchartrain, it’s also exciting for scientists, policymakers and conservationists alike. This newly implemented technology has started to shed light on everything from fish migration patterns and habitat preferences to residency time and environmental impacts.
Seeing how fish responded to the brief opening of the Bonnet Carre’ spillway earlier this year is of particular interest. It has allowed us to study how fish might react to a large input of river water during high water events. This technology would also be useful in determining how fish respond to changes resulting from the planned Mid-Breton and Mid-Barataria sediment diversions. Additional research would be needed to understand how this technology can be used to monitor these basins. Nonetheless, an interesting observation was made by Ashley Ferguson, LDWF Biologist and fish telemetry expert, that “under the conditions at the time of the spillway opening, including the cooler water temperatures and the short 22-day opening, adult tagged spotted seatrout (speckled trout) and red drum (redfish) were not observed leaving Lake Pontchartrain.” This observation could help inform how a future sediment diversion might be operated and minimize impact on certain fish populations.
Our coalition of organizations is excited to see this technology being developed and hope its use will extend to other places such as the Breton and Barataria Basins. It could help tremendously with the state’s plan for monitoring and adaptive management of its restoration projects’ impact on fisheries.

May is American Wetlands Month, and Louisiana's coastal wetlands are some of the most productive ecosystems in North America. Not only do they provide habitat for numerous fish, wildlife and birds, but they also help improve water quality, provide recreational opportunities and protection for people and infrastructure from damaging storm surges.
Wildlife habitat and nurseries
Wetlands serve as a nursery environment for juvenile fish. The countless ponds, bays and bayous found in the Mississippi River Delta provide essential habitat for most commercial and game fish found in the Gulf of Mexico. Menhaden, shrimp, oysters and blue crab area all important commercial species that depend on healthy coastal wetlands to thrive. Additionally, fur-bearers like muskrat, beaver and mink, as well as reptiles including alligators call coastal wetlands and estuaries home.
Storm surge protection
Wetlands have an incredible value for people, too. One acre of wetlands has the capacity to hold up to 1 million gallons of water during a flood! On average, damaging storm surges are reduced by one foot for every 2.7 miles of wetlands, reducing wave energy and protecting levees and other critical infrastructure from these destructive forces of nature. The value of community protection for a one-mile strip of wetlands is valued at $5.7 million.
Wetlands also help improve water quality by filtering and retaining residential, agricultural and urban wastes. Reconnection of the Mississippi River to surrounding wetlands would help filter out nutrients that are contribute to a harmful low oxygen area in the Gulf of Mexico dubbed the “dead zone.” The shallow waters of coastal wetlands are good habitat for submerged aquatic vegetation, which can utilize the extra nutrients and potentially reduce the Gulf of Mexico dead zone as well as increasing water clarity.
Restoring Louisiana’s coastal wetlands
Louisiana holds 40 percent of the coastal wetlands in the continental U.S. and is currently experiencing around 80 percent of all coastal wetland loss in the U.S. Work is currently underway to restore and rebuild wetlands in the Mississippi River Delta through projects in the state’s Coastal Master Plan, including sediment diversions and marsh creation. The reintroduction of Mississippi River water and sediment to its delta plain allows new wetlands to build and flourish, providing habitat for wildlife, clean water, places to recreate, and protection for storm surge.
Louisiana’s wetlands are a national treasure worth protecting. Learn more about why wetlands are important: https://www.epa.gov/wetlands/may-american-wetlands-month-learn-explore-take-action.

On Friday, April 22nd, 2016, Restore the Mississippi River Delta Coalition staff participated in an Earth Day tree planting event. Outreach team staff joined their partners at the Lake Pontchartrain Basin Foundation and several volunteers to plant 250 cypress trees graciously donated by the St. Bernard Wetlands Foundation. Our staff and volunteers were thrilled to spend a day working in the wetlands, the sunshine and gentle breeze being a pleasant change from the normal office environment.
The nutrient-rich alluvial soils on the east bank of the Mississippi River create perfect conditions for growing cypress, and scientists at LPBF boast of a 77% survival rate for their volunteer-planted cypress trees. Cypress trees provide habitat for insects and animals, and as their tangled root masses grow, the plants establish themselves in the soil, limiting erosion while filtering water in the swamp. These trees are essential for restoring degraded wetland ecosystems.
Planting cypress in a degraded swamp requires some precautions to ensure the trees survive. Volunteers must select an appropriate substrate—not too wet, but not too far from water either—so the trees can thrive. Small wetland creatures threaten the young trees as well, and in Louisiana, nutria pose a consistent threat. The young trees contain a lot of nutrients, and the large rodents find them particularly yummy. To make sure the trees’ tender roots are protected, we installed nutria guards around their trunks.
Our team planted 250 trees, and though sweaty, sunburnt and exhausted, we could not have planned a better way to spend Earth Day.
