Caron Sharpe is a “natural artist.” Her art is inspired by what she loves and finds in nature in south Louisiana. Caron lived in the Azores Islands as a child and began her life-long fascination with tropical flowers and wildlife. Lush tropical images in her art reflect the islands as well as south Louisiana and her love for all things botanical.
Her favorite subjects are native birds and wildlife, moss covered trees and palmettos. Her unique substrates include antique doors, windows, ceiling tiles and slate. She also creates beautiful work in clay. Her faux painting and trompe l’oeil walls along with entries, windows and wood panels adorn the homes of many clients in Louisiana and around the world. Much of her inspiration comes from drawing at her home on the bayou and her lake house on Becky Lake. Follow her on Facebook at Caron’s Creations | Facebook to view more of her work.
Since 1956, approximately 110 acres of marsh has been lost along
the east shore of Lake Pontchartrain between Hospital Road and
the Greens Ditch. One of the greatest influences of marsh loss in
the area can be attributed to tropical storm impacts. Wetland losses
were accelerated by winds and storm surge caused by Hurricane
Katrina, which converted approximately 70 acres of interior marsh
to open water. Stabilizing the shoreline and protecting the
remaining marsh would protect natural coastal resources dependent
on this important estuarine lake, communities that thrive on those
resources, the Fort Pike State Historical Site, and infrastructure
including U.S. Highway 90. USGS land change analysis
determined a loss rate of -0.35% per year for the 1984 -2011
period of analysis. Subsidence in this unit is relatively low and is
estimated at 0-1foot/century (Coast 2050).
Lake Pontchartrain supports a large number of wintering
waterfowl. Various gulls, terns, herons, egrets, and rails can be
found using habitats associated with Lake Pontchartrain, which has
been designated as an Important Bird Area by the American Bird
Conservancy. Restoring these marshes will protect the Orleans
Landbridge and will help to protect fish and wildlife trust resources
dependent on these marsh habitats, particularly at-risk species and
species of conservation concern such as the black rail, reddish
egret, brown pelican, mottled duck, seaside sparrow, king rail, and
the Louisiana eyed silkmoth.
Borrow material will be dredged from areas within Lakes St.
Catherine and Pontchartrain to create 169 acres and nourish 102
acres of brackish marsh. Containment dikes will be constructed
around four marsh creation areas to retain sediment during
pumping. The lake shorelines will be enhanced with an earthen
berm to add additional protection from wind induced wave fetch.
Containment dikes that are not functioning as shoreline
enhancement will be degraded and/or gapped. Vegetative plantings are
proposed including five rows along the crown and two rows
along the front slope of the shoreline protection berm, as well as
within the marsh platform area.
The project is located in Region 1, Pontchartrain Basin,
Orleans Parish, flanking U.S. Highway 90 along the east shore of
Lake Pontchartrain and areas surrounding Lake St. Catherine.

The recent cold weather in Louisiana may have been the end of the road for some plants as temperatures dipped into the teens and stayed below freezing for full days. The hibiscus in your garden may have survived because you gave it extra insulation, but what about marsh plants? Louisiana salt marshes are home to black mangroves (Avicennia germinans), but this represents the very northernmost part of their range. Of the three mangrove species found in the continental United States [red (Rhizophora mangle), black, and white (Laguncularia racemosa)], black mangroves are the most cold-hardy, but they are still sensitive to winter weather- they generally cannot establish above 28° N and S latitude because winters are too cold (a sliver of the Birdsfoot Delta is below 29° N, so we really are at their limit).
The three mangrove species are also different in their tolerances for other environmental conditions: red mangroves establish in the intertidal zone, while black and white mangroves are found at higher elevations, and white mangroves can colonize areas with little to no soil. In Florida where all three species occur, mangrove zones can be defined from the water extending inland and up in elevation .
Black mangroves are an important component of Louisiana salt marshes, providing habitat to a variety of species. The complex root systems trap and collect sediment, limiting erosion and maintaining land. Juvenile invertebrates and fish find shelter among the roots, while seabird chicks, such as brown pelicans and roseate spoonbills, are protected from high water events and predators up in the branches.
CWPPRA projects that nourish barrier islands and create new marsh habitat help maintain black mangrove populations by providing new land for the plants to colonize; in turn, the mangroves help the new land persist in the face of wind and wave energy.
Dredging of access and flotation canals for the construction
of I-10 and the Illinois Central Railroad resulted in increased
salinity and altered hydrology in the area that exacerbated
the conversion of wetland vegetation into shallow open
The project’s primary goal is to restore marsh that has been
converted to open water. Project implementation will result
in an increase of wildlife and fisheries habitat, acreage and
diversity, along with improving water quality. In addition,
the project will provide a storm buffer protection to I-10, the
region’s primary westward hurricane evacuation route, and
complement hurricane protection measures in the area.
Project features consist of the creation of 729 acres of marsh
and the nourishment of 202 acres of existing marsh using
dedicated dredging from Lake Pontchartrain. In addition,
10,000 linear feet of tidal creeks will be created. The marsh
creation area will have a target elevation the same as average
healthy marsh for this region. Plans are to place the dredge
material in the target area with the use of low level, noncontinuous
retention dikes along the edge of the project area
allowing overtopping of material to nourish the marsh fringe.
Vegetative plantings will be utilized in the areas deemed
most critical by the project team. Successful wetland
restoration in the immediate area (PO-17) clearly
demonstrates the suitability and stability of soil and material
availability from a sustainable borrow area.
The project features are located between Lake Pontchartrain
and I-10 in St. Charles Parish, Louisiana. It is bounded on
the west by the Fall Canal and the Bayou LaBranche
Wetland Creation Project (PO-17) and the east by a pipeline

Families enjoying a Saturday adventure together on March 11th had the chance to explore different aspects of the ecosystems around them, including ways that wetlands help them and native wildlife. Coastal Wetlands Planning, Protection, and Restoration staff exhibited materials and games at the Estuarine Habitats and Coastal Fisheries Center as part of 2017 Family Adventure Day to benefit the non-profit Healing House in Lafayette, LA. This annual event sends families to different locations throughout Lafayette for experiences that range from face painting to coming face-to- face with a snake.
Over 250 people stopped by the Center where they had the opportunity to see a demonstration of how coastal wetlands protect interior communities and wildlife habitat from storm surge. Visitors could pick up recent issues of WaterMarks and other materials on wetlands restoration projects in coastal Louisiana. Kids also received Henri Heron’s activity book and helped match Louisiana wildlife with the wetland habitat they need to survive.
Other exhibitors, including US Fish & Wildlife Service and Louisiana Dept. of Wildlife & Fisheries, focused on topics like bat conservation, beekeeping, endangered species in Louisiana, and fishing. Helping families understand and appreciate the diversity of natural environments in Louisiana helps ensure that those environments will be present in the future.
Louisiana’s shorelines are eroding at a drastic pace, some at rates up to 50 feet per year. The fertile but fragile soils found in the wetlands are susceptible to wave energy. As land is lost, water bodies merge together, which can increase wave fetch and shoreline erosion. Behind these shorelines lie communities, highways, and infrastructure that are at risk of washing away.
Various techniques to defend the coastline have been tested and applied under CWPPRA. Rock revetments, oyster reefs, concrete panels, and other fabricated materials have been constructed along otherwise unstable shorelines to abate wave energy and reduce erosion. These structures are designed to break waves, and they often trap waterborne sediments behind the structures that, over time, can become new land.
Through the course of the CWPPRA program, advancements have been made in shoreline structures that have helped maintain natural processes while providing critical protection. Such advancements have included using lighter-weight materials that require less maintenance and can be constructed on organic sediments. Other advancements include low-relief structures that are designed to trap sediments and natural breakwaters such as reefs that can self-maintain and support other ecological functions. Other natural shoreline protection measures include vegetative plantings, whose roots help secure soils and can promote accretion. These projects are implemented with consideration for minimizing impacts to the surrounding environment. Although some shoreline structures may look foreign in a natural landscape, they are necessary features that physically protect communities and hold wetlands in place by mitigating the harsh forces that move to destroy them.
Environmental Studies students in Christina Hidalgo’s class at the Episcopal School of Acadiana do more than learn about general environmental issues; they also get outside and participate in direct monitoring of the ecosystems around them. On February 21st and 23rd they were joined by Coastal Wetlands Planning, Protection, and Restoration Act staff to discuss coastal habitats, the mammal species that call them home, and different wildlife monitoring techniques.
On Tuesday CWPPRA staff and ESA students discussed the importance of barrier beach systems for both human and wildlife communities, and students were given training in how researchers trap small mammal populations in those locations for monitoring. After students deployed small mammal traps around the ESA Cade campus on Wednesday, CWPPRA staff returned Thursday morning to help with trap collection and see what students had captured. In addition to trapping a variety of insects drawn to the oatmeal-soybean bait and several traps which had been moved by larger animals, ESA students successfully captured a marsh rice rat (Oryzomys palustris)!
These rodents are found throughout the Gulf and mid-to-south Atlantic coasts and as far inland as Illinois and Kansas. As the name suggests, marsh rice rats are generally found in wetland areas, although drier areas with dense grasses and sedges, while not ideal habitat, are also utilized. A native species in Louisiana, marsh rice rats can even be found out on barrier islands where their omnivorous diet lets them take advantage of both terrestrial food resources and items that wash ashore. The rat captured on the ESA campus was trapped near a stream and probably forages along that water body at night. Finding a marsh rice rat on a school campus is a reminder that wetland habitats come in a range of sizes and types and that we share those habitats with many different species.
Known to be one of the most easily recognizable species of waterfowl, the mallard duck is majestic, distinctive, and a wintering resident of the bayou state. The mallard is one of the most common ducks in the United States. With great variation between the two mallard genders, drake or male mallards have a bright yellow bill, prominent emerald green head, and white neck-ring, followed by a chestnut colored chest and dark colored rear. The hen or female mallards have a dark colored bill and are a mottled brown color with a dark brown stripe across the eye. Both drake and hen mallards have the characteristic violet-blue speculum with black and white borders. Mallard ducks are a migrating waterfowl species that can be found in Louisiana during winter. Among the dabbling ducks, mallards are one of the latest fall migrants with one of the most extended migration periods, lasting from late summer to early winter. During their migrant stay, mallards are found in agricultural fields, shallow marshes, oak-dominated forested wetlands, and coastal inlets with aquatic vegetation. Louisiana sits in the Mississippi Flyway, North America’s greatest and most heavily-used migration corridor. Louisiana’s coastal wetlands provide habitat for more than 5 million migratory waterfowl, approximately half of the wintering duck population of the Mississippi Flyway. Now, more than ever, restoration and protection of coastal wetlands is critical; if wetlands continue to diminish, Louisiana will no longer be known as “sportsman’s paradise”.
A trademark of the freshwater swamp landscapes in temperate climate zones, this deciduous conifer has made its mark as a signature resident of Louisiana, having been named the state tree. The widely adaptable bald cypress thrives best in wet, swampy soils of riverbanks and floodplains and is commonly thought of as a famous inhabitant of American swamplands, such as those that border the Mississippi River. Cypress trees will often have Spanish moss draped from branches and cypress knees protruding from the water or soil surface, as well as terrestrial and aquatic wildlife in close proximity who are dependent upon these trees. Swamp imagery usually includes bald cypress trees which are commonly correlated with Cajun culture. Cypress trees also contribute to a major portion of Louisiana’s forestry industry with an estimated annual harvest of 30 million board feet per year. The town of Patterson was once home to the largest cypress sawmill in the world and is now designated as the Cypress Capitol of Louisiana. Having both historical and economic importance, cypress trees that are at least two hundred years old and alive at the time of the Louisiana Purchase are being identified and landmarked as part of the Louisiana Purchase Cypress Legacy program to commemorate the state’s natural heritage. Cypress trees have been considered essential in the representation of swamp wetlands and hold exceptional importance to Louisiana.
On October 15, the U.S. Fish and Wildlife Service hosted the 19th Annual Wild Things Festival at the Southeast Louisiana Refuge Headquarters in Lacombe, La. This exciting family-friendly event gives the community an opportunity to engage in outdoor activities while celebrating National Wildlife Refuge Week. This free public event included canoe and pontoon boat tours, hayrides, live animals, wildflower walks, kids activities, bird house building, live music, and a youth wildlife art competition.
The Coastal Wetlands Planning, Protection, and Restoration Act Public Outreach staff was among the 40 exhibitors providing hands-on activities to encourage knowledge of the Louisiana outdoors. In order to accurately portray the importance of aquatic, coastal regions, the CWPPRA staff utilized an ocean character, Sid the Restoration Squid, whose six unique legs each represented a different restoration method. The six restoration methods include barrier island restorations, marsh creations, shoreline protection, hydrologic restoration, freshwater and sediment diversions, and terracing. Each leg consisted of a distinct craft material that would correspond with a restoration method, in which children would assemble and personalize their own squid. Each child’s personal squid was accompanied by an explanation guide of CWPPRA’s efforts to restore, protect, and/or create Louisiana’s wetlands.
