WETshop 2017

On Tuesday,  June 11th, the CWPPRA Public Outreach staff traveled to the Louisiana Department of Wildlife and Fisheries Marine Research Lab in Grand Isle, Louisiana to discuss Louisiana wetlands with teachers from around the state. The teachers participated in WETshop: a week-long, dynamic teacher workshop that allows teachers to work with educators and scientists to learn about Louisiana coastal wetlands, issues, and history. The focus of the summer workshop is to create wetland stewards of teachers in order for them to educate coworkers and students in their home parishes about coastal land loss. The workshop was sponsored by the Louisiana Department of Wildlife and Fisheries and the Barataria-Terrebonne National Estuary Program. During WETshop, the teachers get a firsthand look at the importance of wetlands through visiting coastal ecosystems, water quality testing, marsh tours of coastal restoration sites, and the opportunity to learn about fisheries management, coastal botany and ornithology, and invasive species.

The Coastal Wetlands Planning, Protection, and Restoration Act’s Public Outreach staff participated in WETshop as coastal wetland educators. CWPPRA provided each of the twenty teachers with packets containing numerous publications and teaching resources, as well as posters from CWPPRA’s #ProtectOurCoast campaign. The public outreach staff also gave a presentation that highlighted causes of land loss, benefits of wetlands, CWPPRA’s history and success with projects, the Coastwide Reference Monitoring System, and different ways teachers can access and utilize wetland teaching materials.

Bayou Bonfouca Marsh Creation

wordpress fact sheet banner-01

The marsh in this area was fairly stable prior to Hurricane
Katrina in August 2005. There was extensive damage to the
marsh along the north shore of Lake Pontchartrain and
especially localized in the marshes near Bayou Bonfouca
when the storm surge removed many acres of marsh. Marsh
loss rates should increase in the marsh surrounding these
newly created open water areas due to an increase in wind
driven fetch. Within the project area, the Lake Pontchartrain
shoreline erosion rates seem to be very low. Currently, there
is one large breach and several smaller ones in the Lake
Pontchartrain shoreline, with many more breaches seemingly
imminent. These breaches provide direct connection between
the fresher interior marshes and higher saline waters of Lake
Pontchartrain. The breaches in the bankline should be filled
before they grow to become a major exchange point causing
an increase in interior loss rates.

The primary goal of the project is to create 533 acres and
nourish 42 acres of low salinity brackish marsh in open
water areas adjacent to Bayou Bonfouca with sediment
pumped from Lake Pontchartrain.
This project would consist of placing sediment, hydraulically
dredged from Lake Pontchartrain, in open water sites to a
height of +1.2 NAVD 88 to create 458 acres and nourish
approximately 133 acres of marsh. Several historic marsh
ponds have been identified and would be restored. Tidal
creeks are also proposed to connect these ponds to facilitate
water exchange and fisheries access. Containment dikes
would be sufficiently gapped or degraded to allow for
fisheries access no later than three years post construction.

The project would result in approximately 424 net acres of
intermediate marsh over the 20-year project life.

Shell Beach South Marsh Creation

banner-01

The marsh boundary separating Lake Borgne and the MRGO
has undergone both interior and shoreline wetland losses due
to subsidence, impacts related to construction and use of the
MRGO (i.e., deep draft vessel traffic), and wind-driven
waves. Although much of the project area is protected from
edge erosion by shoreline protection measures, and since
2009, the MRGO has been deauthorized for deep draft
navigation and maintenance, interior wetland loss due to
subsidence continues to cause marsh fragmentation and pond
enlargement. Wetland loss rates in the project area are
estimated to be -0.60 percent a year based on USGS
analysis.

The proposed project will create and nourish 634 acres of
marsh using dredged sediment from Lake Borgne. Existing
high shorelines along Lake Borgne, remnants of previous
containment dikes and marsh edge, would be used for
containment to the extent practical. Constructed containment
dikes would be breached/gapped as needed to provide tidal
exchange after fill materials settle and consolidate. The
project would create 346 acres of marsh and nourish at least
288 acres of existing fragmented marsh. A target fill
elevation of +1.2 feet is envisioned to enhance longevity of
this land form. Additionally, 187 acres of vegetative planting
will occur within the newly created areas. Due to the
presence of existing banklines, dredged slurry overflow
could potentially be discharged immediately adjacent to the
project polygons, resulting in nourishment of additional areas.

RAE Conference 2016

Restore America’s Estuaries (RAE) is a non-profit organization dedicated to the protection and restoration of bays and estuaries as essential resources for our nation. RAE member organizations restore coastal habitats in 11 estuaries and 16 states nationwide. RAE is also involved in the economics and valuation of estuaries, blue carbon, living shorelines, national advocacy, and a wide range of coastal restoration issues. The Coastal Society (TCS) is an organization that is dedicated to actively addressing emerging coastal issues by fostering dialogue, forging partnerships, and promoting communications and education. TCS is comprised of private sector, academic, and government professionals and students who are committed to promoting and effectively improving management of the coasts and ocean.

Restore America’s Estuaries and The Coastal Society hosted the 8th National Summit on Coastal and Estuarine Restoration and the 25th Biennial Meeting of The Coastal Society on December 10-15 at the Hilton Riverside Hotel in New Orleans, La. The Summit is an international gathering encompassing all disciplines within the coastal and estuarine restoration and management communities. RAE and TCS  worked with 200 partnering and supporting organizations to develop the Summit program and welcomed more than 1,200 attendees from the restoration and management communities: non-profit and community organizations, Indian Country, academic and research institutions, businesses with an interest in the coast, and agencies from all levels of government. Restoration and management-interested groups or individuals gathered for an integrated discussion to explore issues, solutions, and lessons learned in their work. The theme of the 2016 conference, “Our Coasts, Our Future, Our Choice,” reflected the environmental, economic, and cultural importance of our coasts to residents of surrounding areas and to the nation as a whole.

To initiate the conference’s 550 oral presentations in 110 sessions, as well as 200 poster presentations, the Marc J. Hershman Opening Plenary session on “The Gulf of Mexico- Proving Ground for Regional Recovery Strategies” discussed how restoration in the Gulf is faring as enormous resources start to pour in. The subsequent days highlighted climate change, economic vitality, as well as coastal communities across the nation and the ecosystems they rely upon through sessions, a coastal film series,  and science communications coffee breaks. The closing plenary session covered “Changing Tides: What the New Congress and Administration Mean for Advancing Coastal Restoration and Management” with a panel discussion from leaders in coastal conservation, communications, and climate change policy. Among the 80 exhibitors was the Coastal Wetlands Planning, Protection, and Restoration Act. The CWPPRA exhibit debuted two new posters in the “Protect Our Coast” poster series campaign with accompanying banners in our photo booth, in addition to an array of available CWPPRA publications. As a follow up to the previous Brown Pelican and Louisiana iris posters, a coastal sunset scene and blue crab were each depicted. Participants were able to select from a variety of props to hold or wear while posing in front of the campaign poster banners. Participants posted their photos on multiple social media platforms with the campaign hashtag #ProtectOurCoast.

South Lake Lery Shoreline and Marsh Restoration

banner-01

According to USGS-land loss analysis, much of the southern and western shorelines of Lake Lery and the surrounding wetlands were heavily damaged in 2005 by Hurricane Katrina. In the years following this storm, wind induced waves within the lake have begun to cause further damage to the lake’s shorelines. Currently the shorelines have become so damaged that the interior emergent marshes that are still intact are being exposed to the damaging waves. This has caused an increased loss of emergent marsh habitat. Even with the benefits of the Caernarvon Diversion Structure, without some type of restoration in this area, these marshes may not be able to fully recover.

This is a marsh creation and shoreline restoration project. The marsh creation aspect of the project would utilize a hydraulic dredge to extract material form Lake Lery water bottoms and pump that material into contained marsh creation cells which are located south of Lake Lery. This will initially create and/or nourish approximately 496 acres of marsh (356 Net Acres at Target Year 20). The shoreline restoration project component would have a barge-mounted dragline excavating material from the bottom of Lake Lery and placing that material along 35,831 ft. of the southern and western Lake Lery shorelines. This restored shoreline would have a 50 foot crown width and be built to a height considered high intertidal marsh.

The lake side shoreline would have a 5:1 side slope which would be planted with smooth cordgrass and bullwhip. This would initially create 55 acres of marsh (50 Net Acres at Target Year 20) along the Lake Lery shoreline. Total created/restored marsh acreage for this project is 551 acres (406 Total Net Acres at Target Year 20).

The project area is located in Region 2, within the Breton Sound Basin portion of Plaquemines Parish. The project is specifically located south of the Caernarvon Freshwater Diversion Structure and west of the town of Delacroix, southeast of New Orleans.

As of April 2016, this project is under construction with most of the lake shoreline restoration nearly completed on the southern shoreline. The western shoreline restoration feature is currently underway. There is one marsh creation cell that is nearly completed. A larger dredge will be arriving soon and marsh creation will accelerate. This project is on Priority Project List (PPL) 17.

Land Loss

Did you know:

Coastal Louisiana has lost an average of 34 square miles of land per year for the last 50 years.

The alarming rate at which Louisiana loses coastal land can be seen through projected land loss maps such as the Southeast Louisiana Land Loss Map, which shows historical and projected land loss in the state’s deltaic plain from 1932 to 2050. The Coastal Wetlands Planning, Protection, and Restoration Act works diligently to decrease the rate of land loss for coastal regions along the Gulf of Mexico.
