The Louisiana Iris Conservation Initiative (LICI) organized a Louisiana iris planting on Wednesday, January 16th, 2021 at The Nature Conservancy’s Grilletta Tract in Grand Isle, La. The volunteers included members of the Native Plant Initiative, Grand Isle Garden Club, Terrebonne Parish Bird Club and LICI volunteers.


The iris planting was arranged by Jean Landry, manager of The Nature Conservancy’s Grand Isle properties, to add to the native Louisiana irises already growing on the property. This was the third time that irises have been planted over the last two years as part of Jean’s efforts to increase the number of native plants growing there.

The Nature Conservancy’s Grand Isle properties are there to preserve what were once large stands of trees, including live oaks, that covered the entire island. These trees are the first that birds have to rest on after arriving at Grand Isle from their long journey flying across the across open waters of the Gulf of Mexico through the central flyway from Central and South America. Its also the last chance for birds to rest after coming from across the central areas of the United States on the their way back in the fall before crossing the Gulf of Mexico. Birders from around the country come to Grand Isle and this tract of land because it offers them the chance to see a congregation of different bird species all within a small area.


I. giganticaerulea species of the Louisiana iris were planted by the volunteers. The irises came from the LICI iris holding area in New Orleans from irises that were rescued at a property this past summer that was expanding a parking lot.

freshwater bog located in the center of the property.


The bog is not affected by tidal action, but does flood during high water events associated with tropical storms or hurricanes. Properties on either side of the Grilletta Tract drain into the bog.


Since the Louisiana iris is a fresh water plant, there was some concern that they may not be able to survive tropical systems' storm surges that occur when a storm passes nearby. However, the irises that were planted last year not only survived 2020's hurricane season, which flood the property twice during the fall, but they seemed to be thriving.


It is possible that fresh water from rain associated with a tropical system quickly flushes out any salt water from a storm surge that has pushed up onto the property. Jean said that the storm surge flood waters drain out very quickly after a storm passes because the rear of the property has frontage on the back bay of Grand Isle, but it takes a few days for the rain water from adjacent properties to then slowly drain off through the bog.

The overall strategy for the morning was to plant the irises in numerous locations to see how well they do. The areas where the irises thrive will get more irises next year.

January 10, 2021 Port of Manchac, La.


The Louisiana Iris Conservation Initiative (LICI) was invited to plant Louisiana irises on a Coalition to Restore Coastal Louisiana (CRCL) cypress tree planting volunteer event on Saturday, January 9, 2021. The plan was for some of the volunteers taking part in the CRCL event to plant Louisiana irises at the site of the tree planting as a test to see if irises could be added into future planting events, since cypress trees and irises are found growing naturally in the same habitat. This is the second year that this was attempted, with two events last year being cancelled do to high water at the site.

As stated on their website; "The Coalition to Restore Coastal Louisiana (CRCL) is a nonprofit organization whose mission is to drive bold, science-based action to sustain a dynamic coastal Louisiana through engagement and advocacy."


Incorporated in 1988, CRCL represents a coalition of businesses, local governments, industries, scientific communities, national and local conservation groups, hunters, anglers and concerned citizens who all share a common vision and commitment to the sustainability of coastal Louisiana.

Six of the volunteers spent the morning planting I. giganticaerulea species of the Louisiana iris supplied by LICI as the other volunteers planted cypress, tupelo gum and swamp maple trees.

The irises came from a LICI iris rescue project done this summer. They have spent the last few months strengthen up at the LICI iris holding area in the lower ninth ward neighborhood of New Orleans. On this day they were being returned to the wild, but in a much better location from where they came.


The planting site was located along north pass of the Manchac Pass about a mile from the dock.



The morning had a cold start to it, but it quickly warmed up enough to make the day doable. It was a full sunshine day with a light breeze.


Photo on left: One group planted irises about 12" - 24" from what appeared to the normal water line. The rhizomes were pointed in the direction of the water with the idea that they will grow out into it to escape competition from the other marsh plants.


The property is owned by Southeast Louisiana University in Hammond, La. The university maintains a nearby research station named Turtle Cove.


One of the SLU professors involved in the Turtle Cove research station came out to observe the tree and iris plantings. She took GPS readings for each location of where the irises were planted. Her plan is to share the locations with LICI. She said she will be back to the site each year to monitor the success of the tree planting project, but will also include how the irises are doing in her reports.

It was a great day that will likely open up many more opportunities in the future for the LICI to accomplish its mission of reestablishing the Louisiana iris in areas where it once grew in abundance.

January 3, 2021 Lockport, La.


The Lockport Elevated Wetlands Board Walk has been added to the list of boardwalks and trails in southeast and south-central Louisiana where the Louisiana Iris Conservation Initiative (LICI) is doing iris planting projects. A local group of iris enthusiasts asked LICI to consider planting irises along the boardwalk, and after receiving permission from the landowner and the town, the project was initiated.


In three separate volunteer planting events held during December and January hundreds of the Louisiana Iris species I. giganticaerulea iris were planted. The iris is known locally as the "Giant Blue" iris.

On the second iris planting, held on December 23, 2020, the crew made a very interesting discovery when they spotted a rather large, naturally occurring stand of Louisiana irises, also likely the Giant Blue iris, in a small clearing some distance from the boardwalk. The irises were pretty far out in the swamp from the boardwalk and the view out to them was partially blocked by small trees and some vines. This prompted them to clear a path to vegetation, mostly low hanging branches, dead limbs, and damaged and unhealthy saplings, to allow a better view of the irises from the boardwalk.


Some of the irises along the edges of the clump were growing in deep shade and are competing with tree roots. Those plants may be dug up in the future and moved closer to the boardwalk in an open area to get them into a more productive spot and for better viewing by visitors.

boardwalk.

One goal of the second planting planting was to get some irises out near an open area of the swamp at the end of the boardwalk.


During the third planting held on January 2, 2021 the group worked on relocating some of the irises in the large existing clump of irises that was found during the second planting at the boardwalk. Irises that we in locations where they were competing with tree roots were moved to locations with more sunlight and less competition. Additional limbs and some smaller trees were also cut to put the clump better into view from the boardwalk.

Gary Salathe, with LICI, said, "We'd like to thank the landowner, Hugh Caffery, for granting us permission to plant the irises. Also 'thanks' goes out to Lafourche Parish Councilman, Armand Autin, and the Lafourche Parish government employees who assisted with the coordination of this project. All were excited to have the irises added to the boardwalk area and are encouraging us to continue the plantings."
