The following is my introductory posting for this World of Irises blog. My name is Gary Salathe and I live just north of New Orleans on the outskirts of Madisonville, a small town in Southeast Louisiana. I am a member of AIS, the Society for Louisiana Irises (SLI) and the Greater New Orleans Iris Society (GNOIS).
I’d like to start off by thanking Bryce Williamson and Andi Rivarola for inviting me to become a regular blogger, joining the illustrious list of other World of Irises bloggers. I’ll try my best to live up to their expectations.
I’ve come to their attention because of the efforts I and others have been involved in to reintroduce native Louisiana iris species back into marshes and swamps of Southeast Louisiana in areas where they once grew in abundance.
I made a decision earlier this
year to split off my iris restoration activities and form a new non-profit with
other like-minded individuals to concentrate on just this effort after
spending a number of years dividing my time between various duties as a board of
directors member and volunteer of the GNOIS.
This first blog posting will be an attempt to explain the “why and how” of what we hope to accomplish with our new non-profit by continuing and expanding our efforts, which we started three years ago within the GNOIS. Future postings will be used to keep you updated on these projects.
Back in the early 1900’s Louisiana irises were so common in southeast Louisiana they were just thought of as weeds by the locals. It was just a plant that clogged up their ditches. Their abundance was taken for granted. But warnings began to appear in the following decades about how the draining and development of swamps threatened this native plant’s long-term survival. Caroline Dormon, Percy Viosca and Dr. John K. Small, each a botanist, naturalist and early environmentalist, gave the first warnings starting in the 1920’s as they began to publicize this native plant and its habitat. They saw the destruction first hand as they collected iris specimens from the swamp.

The plight of coastal areas of
Louisiana from natural subsidence and erosion which has been accelerated by
man-made activities has been well publicized. The irises have retreated
back into the deepest reaches of the freshwater swamps as salt water has
advanced inland. Combined with the increased use of herbicides by
governmental agencies for roadside maintenance, it has become increasingly
difficult for the people of Southeast Louisiana to experience first-hand wild
irises in bloom each spring.
The result is that a whole generation in Southeast Louisiana has never seen the springtime bloom of wild
irises. It's difficult to motivate people into helping do something about
this loss if they have never seen a wild iris blooming in its natural
habitat. As they say; "Out of sight, out of mind."
Photo: Many of the parishes in Southeast Louisiana now rely on spraying roadside ditches with an herbicide to control weeds. Unfortunately, many of these ditches once held huge numbers of native irises which put the annual iris bloom on full display to the public.
What has been less publicized is
that Louisiana with the federal government’s help is fighting back against
the land loss and salt water intrusion. A master plan has been created and is
being put into effect to do large scale marsh restoration projects using state and federal funds and
money from the B.P. oil spill penalties. The
Mississippi River, hemmed in by levees since the late 1800’s, is once again
being opened up into the marshes through new control structures that will allow much
needed fresh water and silt deposits to push back the salt water and rebuild
land. Although no one believes this will ever reclaim all of the land
that has been lost, early results show that land loss is slowing down and new
land is being created in isolated areas where the first of these Mississippi River diversions have
been built.

The marsh restoration projects are creating opportunities to reintroduce native plants into marshes that previously held brackish or salt water and now have returned to being fresh water.
Non-profit organizations have sprung up to begin reforesting these areas with cypress trees, so we asked a simple question, “Why not include native Louisiana iris species in this effort?”
We
also discovered that all but two of the numerous swamp boardwalks found in the
area’s wildlife refuges, national and state parks and public nature preserves had no
Louisiana irises growing next to them.
We felt that a real opportunity existed to bring the native
Louisiana irises back into the public’s consciousness by
planting irises along these boardwalks where they will be permanently protected
and be in view to the public as they bloom each year. Once this is accomplished our thought is that demand will increase for irises to be used in commercial and governmental marsh restoration projects, furthering our long-term goals.
The Boy Scout Road Trail boardwalk in the US Fish and Wildlife Service’s Big Branch National
Wildlife Refuge is located in a marsh that decades ago changed from being a fresh water
marsh into a brackish marsh and has now changed back into being a
fresh water marsh. Although there are thousands of irises growing on a trail less than 1/4 mile away, there were no irises growing along the boardwalk where a majority of the refuge visitors go to instead.
We then discovered that still to this day there were irises being destroyed because of properties being developed.

We also found that there were many homeowners who had dug up wild irises years ago from nearby swamps and planted them in their ponds or around their homes and are happy to donate them now.

We concluded that “rescuing” irises from being destroyed because of development and thinning out irises on homeowners’ properties offered us the possibility of a ready supply of plants to use in marsh restoration projects.
Our first step would be to plant these irises next to boardwalks that were being used by people to experience and learn about the swamp and marsh habitats. It would allow them to see this unique native plant growing and blooming in its natural habitat, the first time for most of them.
Since all that I am describing involves hard sweaty labor we set out to find younger volunteers that would help get the job done. We discovered that many young people want to help out in saving the environment and they felt that reintroducing irises back into the swamp as accomplishing this. We connected with local organizations that bring in college students from around the country to volunteer on marsh restoration projects and they included our iris restoration projects for their groups to work on.

With all of the pieces in place we spent the last two years developing the program. In late 2018 to early 2019 we rescued and replanted 8,000 I. giganticaerulea irises. From October 2019 to January 2020 we rescued and replanted almost 13,000 more.
At many of the places where we planted the irises the managers and their staffs were being introduced to the Louisiana iris for the first time. Although irises may have been found somewhere on their properties, saving or managing the lowly iris was not on their priority list. However, they are now fully on board after two seasons of seeing the excitement the blooming irises created among visitors to their boardwalks. The Louisiana iris has now moved up in importance.
In late April we launched the new non-profit to continue the program on a much larger scale. It is named the Louisiana Iris Conservation Initiative (LICI).

Then COVID 19 hit. But we discovered two things: There were enough people in our area that had time on their hands and were itching to get out of the house and accomplish something because of the lock-downs that we could still get volunteers and they were also willing to do more events than what we would typically expect. Even though we were working in smaller groups because of the social distancing requirements we were able to do more events because the volunteers had the time to give. At one point about six weeks ago we actually did two volunteer events on two different days in one week for two weeks back-to-back. (Whew!)
Photo: LICI volunteers are shown setting up the iris holding area in July. We kept the number of volunteers for each event to ten people or less in keeping with social distancing protocols for fighting the COVID 19 virus.
We solicited and received donations from various organizations to set up an iris holding area to plant the irises we rescued into containers for them to strengthen and grow to get them ready for planting in the marsh this fall and winter.
And
that’s where we stand, as of today.
We are hopeful that the college student volunteers from around the country will begin to return next spring.
We
believe we have close to 6,000 I.
giganticaerulea species Louisiana irises growing in containers at our iris
holding area. We’re taking a little
break and then will start up later this month visiting sites and getting the
needed permits to prepare for planting them.
The demand for these irises is so great that we believe we can get all of
these irises planted by the end of November and dig up a whole second batch for
planting in January if the irises and local volunteers are available.
Our volunteer events will need to be spaced out
and likely done on weekends now
that things are loosening up on the COVID 19 lock-downs and many people in our
area are going back to work. We had
hopes of rescuing and replanting 20,000 irises this season, but it will all
depend on whether or not the volunteers are available. No matter, our plan is to give it our best
shot.
Stay tuned for future postings as things develop!!
