Southern Chapter Report
by Skip Kincaid, Southern Chapter Executive Director
Based on recent weather events, I’m hopeful that you are snuggled up next to a fire or wood stove! If the temps aren’t that low, then my wish is that you get outside and enjoy a walk among the trees. Whether you consider yourself in the “environmental” camp or not, a walk in the woods treats the mind well. Our minds here at ISA Southern Chapter are good as well. A few of us are dealing with whatever cold virus is going around and we have a few bone issues. But overall, I think we’re handling winter rather well and we’re focused on your professional needs and preparing a fantastic conference. Ahhh, the conference you say? What about the conference? Well, check it out HERE
I know I tend to be a bit overdramatic about each year’s conference. But I ain’t lyin’ when I say I think we’ve outdone ourselves this year. Most of you are aware that the ISA Conference this fall will be in New Zealand. Great place to travel, but not everyone will be able to make that trip. That’s where we come in …. Our 83rd Annual Trade Show and Conference is being called “ISA Southern Professional Development Week” for a reason. The week starts on Saturday, April 5, with the Tree Climbing Championship at the very cool Memphis Botanical Garden. Monday through Wednesday, we are planning four separate pre-conference workshops and events. The most exciting of these is a three-day Prescription Pruning Workshop (PPQ) taught by Dr. Ed Gilman and Lindsy Purcell. This new credential was developed by the Florida Chapter and is becoming a popular addition to your pruning knowledge. There is a one-day option for this workshop as well.
And the last two days of the week, Thursday and Friday, are stuffed with some of the industry’s most popular speakers including Dr Gilman, Dr. Tom Smiley (past Southern Chapter President and current ISA President), Dr. Kim Coder, Dr. Glyn Percival, Paul Johnson, Dr. John Ball, Scot Carraway, Michael Johnson, and many more. It’s a safe bet to mark your calendar and get registered now.
A few other items to look for in the coming months… more TRAQ courses. In addition to the class in Memphis, look for other classes near you. If you are TRAQ already, check your expiration and get signed up for a virtual renewal course. You can renew any time in the 18-month period prior to your expiration date. Big news is coming about TRAQ renewal requirements, and it will benefit to renew as early as you can.
We are in the early stages of planning a return of the immensely popular tree decay workshop with Chris Luley and Frank Rinn. We’re looking at Baton Rouge as the home base and penciling sometime in late September. So stay tuned because it will fill very quickly!
Wanted to mention that I am hearing from what seems to be an increasing number of people that want to “become arborists.” Not sure what brought about this sudden bump, but Amen! It’s nice that they reach out to ISA Southern Chapter and we provide what we can in terms of direction. Of course, I point them to local groups to join to get involved locally and also to consider becoming an ISA Certified Arborist or Certified Tree Climber. Credentials are a great way to put a bump in your knowledge and confidence.
Last reminder is to be on the lookout for a ballot coming your way via email in late February. It’s election time and the nominations committee is filling the ballot with great candidates. You can visit the Chapter Board of Directors page to see who your representatives are. If interested, there is an application to get on the ballot on that page as well. The nominations committee will then select candidates to be on the ballot.
That’s all the news I have from the woodpile. Don’t forget to get outside and enjoy it!
Louisiana Back ON TRAQ
by Brian Watkins, Vice President
TRAQ finally made its way back to Louisiana. BREC’s Anna T. Jordan Community Park was home to the event that took place December 17-19, in Baton Rouge. 20 professionals from across the United States gathered for the two-day class, taught by Jimmy Walters. This class was very informative and gave all the professionals a new way to look at tree risk. Not only did we learn about tree risk, but we made connections that will last for a lifetime.
This TRAQ course is just one of many courses/trainings that will be offered in Louisiana. We are trying to bridge the gap between Louisiana arborist professionals and the Southern Chapter. This has not been easy since Louisiana has its own state arborist license. The Southern Chapter and your Louisiana Director will continue to host events that will add value to Louisiana professionals, and the TRAQ course was a step in the right direction.

Vascular Streak Dieback (VSD)
An emerging threat to the nursery production in the southeastern US
by Dr. Fulya Baysal-Gurel, Tennessee State University, Otis L. Floyd Nursery Research Center
Vascular streak dieback (VSD), first identified five years ago in eastern redbud in Tennessee and red maple in North Carolina, has become a major concern for nurseries across multiple states, including Tennessee, Virginia, and North Carolina, with isolated cases in Indiana, Florida, and Oklahoma. VSD has been detected in newly planted landscapes, botanic gardens, and natural areas, significantly impacting eastern redbud and more than 25 other woody ornamental plant genera. The economic impact on redbud, red maple, and dogwood alone is estimated to exceed $175 million.
VSD symptoms vary by host and include stunted growth, yellowing, dieback, leaf scorch, vascular streaking, and poor root development, which can mimic other conditions like Verticillium wilt, bacterial leaf scorch, and laurel wilt. Co-occurring pathogens, such as Botryosphaeria canker fungi, often complicate diagnosis. The disease has caused significant losses for the nursery industry, with rejected shipments, canceled orders, and widespread destruction of symptomatic and asymptomatic plants due to Stop Sales orders.
Researchers suspect a fungus, Ceratobasidium sp . (Csp), as the primary cause of VSD and Dr. Baysal-Gurel’s team at Tennessee State University (TSU) has developed a molecular diagnostic tool to accurately detect Csp in potentially infected host plant material. These tools, if validated, could enable faster diagnosis and reduce crop losses. However, fulfilling Koch’s postulates to confirm Csp as the causative agent has been challenging due to difficulties isolating and cultivating the fungus. Researchers are investigating whether VSD is solely caused by Csp or influenced by additional pathogens and abiotic factors. Currently, no definitive chemical treatments exist for VSD. However, recognizing the urgency of assisting nursery producers,
the TSU team collaborated with industry partners to conduct fungicide efficacy trials in 2022 using redbud plants naturally exhibiting VSD-related symptoms. The results indicated that foliar applications of Postiva (FRAC 3 + 7) at 20 fl oz/100 gal and Mural (FRAC 7 + 11) at 7 oz/100 gal at 14-day application intervals were the most effective treatments in reducing leaf scorch associated with VSD on eastern redbud seedlings, on three-year-old plants, and several two-year-old budded cultivars growing in field and container settings. These treatments also reduced the population levels of canker-causing pathogens such as Botryosphaeria and Didymella. Although some treatments were identified as effective in reducing symptoms, they did not cure already-infected plants. TSU is continuing its work to identify more effective chemical treatments.
Another research focus is identifying VSD-tolerant redbud cultivars. Screening trials revealed that cultivars with yellow foliage and papery leaves are more susceptible, while those with dark green or purple foliage and leathery leaves exhibit greater tolerance. This information is critical for breeding resistant hybrids. The TSU team and Dr. Hsuan Chen’s team at North Carolina State University are continuing with the cultivar screening, including more redbud species, cultivars, and hybrids, to identify VSD resistance, funded by North Carolina Department of Agriculture and Consumer Services (NCDA&CS) and HRI.
More information about VSD can be found here
Pictured above and right: VSD symptomatic plants exhibit brown- to-gray vascular streaking in the xylem tissue within small stems, branches and the main trunk, stunted growth, decline with water sprouts/ epicormic shoots below the dead branches, chlorosis, necrosis, leaf scorch, and poor root development, and/or tip dieback that may continue into the main stem or stems of the tree and ultimately cause tree death.
Green Careers: Roping In the Next Generation
by David & Christy Raines and Amanda Luster, Raines Tree Care
Seeing the world through the eyes of busloads of teenagers as they walked the corridors and looked in amazement at the many ropes, pieces of equipment, and heavy gear worn by our tree professionals, that likely resembled a video game character’s armor, was amazing! Seeing their desire to grasp new skills as they learned how to tie knots, was inspirational. But watching their determination to win, as they competed against their peers in a knottying competition, was priceless. They may have gone to the 2024 Green Careers Expo expecting only to enjoy a day away from school, but they left intrigued and interested, and so did we. We realized these are the faces, minds, and personalities of our future, and we need them as much as they need us. This excellent event was held at Arkansas Tech University in Russellville, and it was a great way to introduce new ideas to the next generation of plant health care professionals and green space engineers. It was an honor to be invited, and we enjoyed every second of it.
universities, and even shopping malls, never stopping to consider the experience and expertise it takes to ensure the scenery of greenery they enjoy is taken care of in a manner that makes it thrive and come to life.
So what was our goal of being there? To teach, to learn, and to bring more awareness to the opportunities within our arboriculture careers. As a small business trying to garner more interest in the careers that we offer, as well as the high need for certified arborists in our area, it is essential we get the message out to these young and eager populations of graduates that will be entering our workforce in the coming years. In many of our geographical areas, there is a lack of knowledge about the career options available for individuals who are not interested in pursuing a four-year college degree. As well, sometimes there may be a lack of information being introduced in local schools about the importance of green careers.
So often people walk the sidewalks at parks, schools,
The trees, plants and landscaping blend so seamlessly into those environments that people often do not fully realize their purpose. They often don’t understand the amount of oxygen trees emit, the pollutants they prevent, or the habitats they provide. All they know is that it’s beautiful and peaceful, which means we’ve done our job. Building and maintaining green spaces, and ensuring our communities and neighborhoods have beautiful safe trees, is an art, a skill, and a passion; but we need more teammates!
Based on our experience and needs, which are like those of many other green space advocates, small business owners, and tree professionals, we urge you to get involved in events like this in your community. Take the time to introduce information to the up-and-coming graduates in your neck of the woods. Help them understand the opportunities are vast, whether they’re interested in yielding a chainsaw, a clipboard, or becoming a future business owner. What we put into our recruitment efforts now will pay high dividends later. It could help us save forests, enhance biodiversity, and create urban forests. It will help ensure we have healthy green spaces for the mental well-being of our families, as well as homes for insects and our small wildlife friends. Get to know this young workforce, coach and mentor them, as they are the environmentalists and arboriculturists of our future. Our future success depends on their interest in our fields of study, today.

Why Tree Workers Become Certified Arborists and Why They Don’t (with Dr. Beau Brodbeck)
What motivates tree workers to become ISA Certified Arborists? What are the barriers that prevent them from doing so? And why might some choose not to pursue certification at all? In this insightful discussion, Dr. Beau Brodbeck breaks down the findings from his study with Jason Gordon, exploring the various reasons behind the decision to seek—or not seek— certification as an arborist.
TREE Fund Spring Grant & Scholarship Application
Tree Research and Education Endowment Fund’s (TREE Fund’s) Spring 2025 Grant and Scholarship Application Cycle is now open and accepting applications.
Two education grants, one research grant, and six scholarships are available for application this spring. The spring cycle runs from January 15 to March 15. Information and application details can all be found on TREE Fund’s website.
This grant cycle includes TREE Fund’s newest education grant, The Davey Tree Expert Company Community Arboriculture Education Grant, created from The Davey Tree Expert Company Fund Program (The Davey Fund), a permanently restricted endowment fund of TREE Fund. The Davey Fund was created to support community-based arboricultural education in the United States. The purpose of this grant program is to provide funding support for education/ training in tree care and/or urban forestry topics and is designed to support nonprofit educational programs. This grant program will provide two grants of up to $5,000, awarded annually.
How my backyard became a long-term research site
by Chris Diffley, President Elect
“Hey, do you have any clients with several pine trees that would allow me to perform some trial tests on them, that won’t need a lot of notification, and I can come whenever?”
“No, but I have a bunch in my backyard.”
And that’s how I spent the morning hanging out with PA. For those who don’t know, Patrick Anderson is the Director of Research and Arborologists at Rainbow Ecoscience and my favorite person to bother with PHC questions or consulting scenarios. At any given moment, he has approximately 3 billion research tests going on for various products and application techniques to determine efficacy and efficiency.
In this case, he needed to test their new dual port quantum injector on pines to determine how long it would take to complete the process. At the far back of our property was an old stand of planted pines that were never harvested, making a perfect testing ground for him.
The second education grant is endowed by the Ohio Chapter ISA Education Grant Program, which is an education grant focusing on arboricultural education programs or projects within the state of Ohio. That grant amount is also $5,000.
We treated three pine trees approximately 15 inches DBH and he took notes of the current temps, conditions etc … and we spent the morning talking trees. He then mentioned wanting to return in the spring to try again under different weather conditions to see if there were any significant changes. Which I said was fine, I just needed official designation as a research facility because these are the things I find important.
PA can be found talking all things PHC around the country and often at ISA Southern events, and yes, of course, I called him 2 weeks later to tell him all the trees had died (they hadn’t but if you ever have an opportunity like this, I highly recommend you do the same).
The Utility Arborists Research Fund Grant Program is a research grant that focuses on research that is beneficial to utility tree care professionals. Now entering its 15th year, this program is co-sponsored by the Utility Arborist Association and provides grants of up to $50,000. Application for this grant program requires letters of intent to be submitted by March 1, with applications due by March 15.
Applicants for this cycle’s grant and scholarship offerings will also be the first to use TREE Fund’s new Application Portal, a new online application platform designed to streamline the process and help applicants keep all their information organized in one place.
“We are thrilled to launch this new application process, which will benefit not only our applicants but also our TREE Fund review committee volunteers, who dedicate countless hours to reviewing applications,” said Heath Hupke, TREE Fund Grants and Development Manager.
TREE Fund has six scholarships available this cycle for undergraduate students or high school seniors that are interested in pursuing studies and careers in arboriculture and related disciplines. The six scholarships- Bonnie Appleton Memorial Scholarship, Robert Felix Memorial Scholarship, Larry R. Hall Memorial Scholarship, Will Nutter Memorial Scholarship, Fran Ward Women in Arboriculture Scholarship, and John Wright Memorial Scholarship- all offer $5,000 scholarships to students. Applications for these must be submitted by March 15.
“We are very excited to be expanding our grant program offerings this year,” said Paul Putman, TREE Fund President and CEO. “We had a large increase in grant applicants in 2024 and the competition for these grants tells us that the demand remains high. We are proud to be able to fund some of the most useful and cutting-edge research out there for the tree care industry and those who work with and care about trees. As our number of grant programs grow, so does our ability to get new knowledge into the hands of tree care professionals and their communities.”

“Can we get this work scheduled before winter kicks in?” “Do you complete tree work during the winter?” These are questions that I am often asked as the hibernal or winter solstice has arrived. In many cases, winter is the only time we can complete certain projects. This is due to the fact that many diseases and insects are not active, canopy visibility is increased, impact on landscapes is lessened due to winter’s colder conditions, and wildlife regulations are not in effect. Winter can be the perfect time for tree work. Read more
