September 12, 2023 Abbeville, La.
The Louisiana Iris Conservation Initiative (LICI) has a Louisiana iris restoration project underway with their partners, the Friends of the Palmetto Island State Park, in the boardwalk swamp at Palmetto Island State Park near Abbeville, La. Part of the 2023 plan for the long-term project is to plant 600 I. nelsonii species of the Louisiana iris in the boardwalk swamp this fall. (The I. nelsonii irises is known locally as the Abbeville Red iris.) One critical job that needed to be accomplished was to remove the Chinese Tallow invasive tree species from the boardwalk swamp where the irises would be planted.
This August 2023 photo was taken from the Palmetto Island State Park boardwalk of the swamp where the irises will be planted this fall. All of the trees that are 30' tall or
smaller seen in the photo are the invasive Chinese Tallow tree.
The Chinese tallow is a drought-tolerant tree native to China and Japan. It was first introduced in South Carolina during the 1700s as an ornamental tree and then for making soap from seed oils. It was planted from eastern North Carolina southward to Florida. From Florida, it spread westerly through Louisiana and Arkansas into Texas.
Photo: Chinese tallow trees can be identified by broad, waxy-green leaves, often with an extended tip or “tail.” New growth briefly appears reddish.
In the early 1900's, it was used as an ornamental tree in Louisiana because most of Louisiana's native trees do not produce fall-colored leaves. The Chinese tallow tree does.
Photo: The Chinese tallow tree can be easily spotted in Louisiana forests when its leaves change color in late fall. Once this happens, the green color starts to fade from the leaves, and then reds, oranges, and yellows become visible. The leaves from most of Louisiana's
native hardwood trees turn brown in color.
The south/central part of Louisiana, where the Palmetto Island State Park is located, is part of Louisiana's Acadiana region, also known as cajun country. The Chinese Tallow tree is known as the Chicken tree in the region.
The Chicken trees needed to be removed from the park's boardwalk swamp before the two iris plantings planned for later this year. This was because the Chicken trees would compete with the irises, just as they were competing with the native Bald Cypress in the boardwalk swamp for moisture and nutrients in the soil. Also, trying to remove the Chicken trees after the irises were planted would risk volunteers trampling the irises. LICI and the park manager decided to set September 9th as the day to remove the Chicken trees.

He told the history of the Abbeville Red iris and its discovery. He also spoke about why the display of these irises at the park's boardwalk is so important to so many people, literally from around the world, as a place to see this rare species of Louisiana iris when they bloom.

The September 9th event was co-hosted by Palmetto Island State Park and the Louisiana Iris Conservation Initiative (LICI), with the Friends of Palmetto Island State Park, Inc. sponsoring the event by supplying snacks, drinks, and sandwiches. In the days leading up to September 9th, it became a community-wide event with volunteers signing up from a Scout Troop in Lafayette, Abbeville Rotary Club, Abbeville Garden Club, Vermilion ARCH 4-H club - including some of the parents, Friends of Palmetto Island State Park, Inc., volunteers from people staying at the park, and LICI's volunteers. Approximately 50 volunteers showed up for the event.
The swamp was dry due to the extreme drought the area has been experiencing, which made it easier for the volunteers to get around to do the work.

The park manager, Andrea Jones, was very supportive of the effort. She found many of the volunteers, allowed her staff to help deliver, set up, and take down everything needed for the event at the boardwalk base station, and allowed the group to use the nearby meeting room building and its porch.

Small red flags were set next to each Chicken tree so the volunteers would not need to determine which trees in the swamp needed to be cut down. Then, volunteers with either tree limb loopers or a chainsaw would cut the trees down. The cut trees were hauled to the swamp's edge and left to rot among the palmettos. A select few volunteers would then squirt each tree stump with a herbicide to kill the roots. They would collect each red flag as they were finished. Most trees ranged in size from twenty feet tall or less with a 1" to 1 1/2" diameter trunk.

As a way to add a festive feeling to the event, a local aspiring singer/songwriter Brody Lemaire, along with his singer and percussionist sister, Zoey Lemaire, offered to donate their time to come out and play for the other volunteers as they worked. "Their playing and singing were a wonderful background for the groups working out in the swamp," Gary Salathe, president of the Louisiana Iris Conservation Initiative, said afterward.

At the end of the event, Salathe said, "I have no idea how many Chicken trees were pulled up or cut down, but it was a lot! When the Abbeville Red irises we will be planting this winter bloom throughout the swamp at the boardwalk next spring, everyone will have a clear view of the show, thanks to the work of the volunteers today."
