Lenny Farlee, sustaining hardwood Extension specialist for Purdue’s Department of Forestry and Natural Resources (FNR), has been named a 2024 Fellow of the Society of American Foresters (SAF). The SAF Fellow Award, one of the highest honors bestowed on an SAF member by their peers, recognizes long-standing service to forestry at the local, state, regional and national levels.
Farlee was honored with the award during the 2024 SAF National Convention, which took place in Loveland, Colorado from Sept. 17-20.
Zhao Ma accepts the 2024 Family Forests Education Award on behalf of Lenny Farlee and the other project team members.
“Being named a Fellow of the Society of American Foresters is particularly meaningful to me since it originates from a nomination by my peers at the state level,” Farlee said. “I am very grateful that my colleagues in forestry here in Indiana considered my service worthy of recognition, and I owe much of the credit to them for their support of me through my career. It has been my privilege to serve the people and the profession as an Extension forester here at Purdue.”
Farlee educates people about forestry in many ways, including through the popular Extension YouTube series “ID That Tree,” which has over 100,000 views.
Farlee, Ronald Rathfon, Don Carlson, Jonathan Ferris,Dave Osborne and Phil Woolery worked together to develop the course. The course introduces forest landowners to the biology and management of forests and what resources and professional assistance are available. According to survey results from 2021 participants, “94.4% stated that the information was useful to help them make future decisions and 92.5% stated that the information was useful to help act to manage their property objectives.”
“We in FNR, along with forestry professionals in Indiana and the landowners who have communicated with Lenny and his colleagues through the ‘Forest Management for the Private Woodland Owner’ course, know how valuable this program has been to sustainable forest management in Indiana,” said Zhao Ma, interim department head and professor of forestry and natural resources. “So it is absolutely wonderful when others outside of our FNR community and beyond Indiana also recognize the excellent work that Lenny and his colleagues have been doing…, I would also like to share one more note about Lenny – not only has Lenny been a highly valued and respected member of FNR and the forestry profession for many years, but he is also one of the nicest people I have met. He is knowledgeable yet humble, effective yet gentle, serious about his work yet able to have fun, very busy yet always willing to help others and try to be present. We are lucky to have Lenny as our colleague in FNR.”
Morning AgClips — Nestled within the cool, flowing waters of Indiana’s Blue River, the elusive hellbender thrives under big, flat rocks, seeking refuge from predators and finding the perfect conditions to lay their eggs. But in recent years, they have become increasingly difficult to find.
Morning AgClips interviews Purdue hellbender team for details regarding Farmers Helping Hellbenders Project, aimed at restoring Indiana’s endangered hellbender salamander population by improving water quality in the Blue River-Sinking watershed. Learn more about this initiative by hearing directly from the people involved, with the two overarching goals being about improving hellbender habitat and also enhancing local farming operations. Particularly, the project engages farmers in adopting sustainable practices as well, while strengthening conservation efforts for hellbenders.
Hellbenders used to have a much larger range, occurring in most of southeast Indiana’s tributaries to the Ohio River and in the Wabash River. Sadly, its population has dropped drastically due to modification of stream habitats including the accumulation of sediment, agricultural and industrial pollution, warming waters and the channelization of streams and rivers. Because of their decline, these endangered ancient amphibians, with their large, unique flat bodies, have become the focus of an ambitious conservation effort led by Purdue University.
“The significance of the hellbender and its conservation extends beyond the species itself,” Purdue Extension Wildlife Specialist, Nick Burgmeier explains. “Hellbenders are an indicator species; their presence reflects the health of the water quality. Historically common and a top predator in streams, their decline has ecological repercussions, particularly on crayfish populations, which can disrupt food webs.”
Purdue Landscape Report: August was National Check Your Tree Month, but this is something that every tree owner/manager should be doing year-round. As the last hot days of summer are finishing up and we look forward to cooler fall days, we can look to our trees for different signs of trouble.
Most people tend to look up at the canopy before anything else in trees. Check leaves for dieback, discoloration, stickiness or signs of chewing. Check branches and the main stem for damage like splits and breaks, peeling bark, tunneling patterns under the bark, oozing wet spots, or sawdust around the tree. These could be signs of issues in the root system, pathogens like bacteria or fungal organisms, insect problems, or structural damage.
This is not an exhaustive list and if you notice these or anything else that seems off, it could be time for a deeper dive into what might be wrong. If you know the species of your tree the Purdue Plant Doctor is a great tool to narrow down a diagnosis. You can also contact your local Extension office or an ISA Certified Arborist.
On a more positive side, you don’t have to be on the lookout for damage, decline, or signs of pathogens and pests. It is also a matter of enjoying the trees in your landscape. Take some time out of your day to sit in the shade especially as we transition from hot summer temperatures into the cooling of autumn. Revel in the color changes as chlorophyll production slows revealing the carotenoids (that give us yellows, oranges, and browns) and anthocyanin (that produces reds and purples). In winter, not only can you better see damage in the canopy hidden by leaves in the growing seasons, but also the structure and architecture of the canopies in different tree species and the differences in bark textures. And in Spring, new growth of leaves and flowers shows us Winter is nearing its end, bringing warmer days.
So check your trees throughout the year. But not only for potential issues and risk management but also for enjoyment. Trees offer us no many benefits and sometimes it takes a little reminder. If you do see any signs of decline or damage, again, be sure to contact your local Extension office or an ISA Certified Arborist.
Purdue Landscape Report: As summer comes to a close, plants are rapidly releasing seeds and the most noticeable are the flying fluffy type. Thistles, asters and milkweed are just a few of the summer-flowering plants that depend on the wind to disperse their seeds, sometimes carrying them miles away to potentially suitable locations, though seeds typically land within a few meters of the mother plant. This may not be a concern if it’s a desirable plant, but can become extremely problematic when that seed comes from Canada Thistle (Cirsium arvense) (Fig. 1).
Figure 1. Canada thistle (Cirsium arvense), growing amongst common ivy (Hedera helix), produces a fluffy seed that is dispersed by wind.
Canada thistle is found on the list of Indiana Noxious Weeds (IC 15-16-7-2), which mandates that landowners take necessary steps to control and contain the spread of this highly invasive species. Formal enforcement of this Indiana Code falls to Township Trustees, though weed control is a responsibility that is often overlooked. Landowners and homeowners shouldn’t wait for a notice, or knock at the door, from a Township Trustee to begin controlling Canada thistle. It’s listed as a noxious weed for good reason.
Canada thistle is a perennial plant that can reproduce from seed or rhizomes making it difficult to control and contain. Each plant can produce thousands of wind-blown seeds that may remain viable for up to 20 years in the soil. Rhizomes are horizontal underground stems that can grow several feet and put out new shoots (Fig. 2). To add insult to injury, if a rhizome is cut or tilled, a separate plant may grow from each piece of rhizome.
Mechanical and cultural control options for Canada thistle are limited and may reduce plant density, but are not effective at eradicating large, established populations in a landscape. A new population, without an established root system, may be controlled with frequent mowing to deplete food reserves and prevent seed production.Small, isolated populations may be controlled with hand-pulling, but this will need to be repeated every few weeks.
Figure 2. Canada thistle (Cirsium arvense) reproduces by growing horizontal underground stems called rhizomes. Rhizomes can send up new shoots several feet from the mother plant.
Chemical control options include pre- and post-emergent herbicides and, in many cases, applications of both types are needed for complete eradication. A pre-emergent herbicide, with an active ingredient of dichlobenil, is effective at preventing seed from germinating, but will not control established plants. A post-emergent herbicide with the active ingredient of clopyralid is the most effective option for home gardeners. Clopyralid is a selective herbicide for broadleaf weeds, but most vegetable and ornamental plants are susceptible. Precautions should be taken to avoid off-target damage. Read and understand the herbicide label before use. The label is the law.
Regardless of the method used, complete control of an established Canada thistle population will take persistence over multiple seasons. If the fluffy seed is beginning to fly from your thistle patch, it will likely take many more seasons to rid the garden of this pest, but it is possible. To win the battle against Canada thistle, it takes serious grit and an effective herbicide, or a good realtor.
Purdue Landscape Report: There have been a significant number of questions and problems regarding triclopyr that have come up this growing season.

General Information about Triclopyr Triclopyr is a selective systemic herbicide belonging to the pyridine class. It is primarily used to manage woody plants, vines, and some broadleaf weeds. Unlike glyphosate, a broad-spectrum herbicide, triclopyr specifically targets the growth hormones in dicotyledonous plants, making it effective in controlling species that are difficult to manage with other herbicides. It works by mimicking plant hormones, disrupting normal growth processes, and leading to the death of the treated plant (Fig. 1).
What Triclopyr Controls Triclopyr is utilized in various settings to control unwanted vegetation. It is effective against species such as:
Woody Plants: Includes trees like tree of heaven and callery pear and shrubs like autumn olive and honeysuckle (Fig. 2).
Vines: Particularly those that can outcompete native flora, such as kudzu or English ivy (Fig. 3).
Broadleaf Weeds: Some herbaceous plants that pose ecological or agricultural problems.
Figure 2. Invasive plants, such as, Pyrus calleryana (callery pear) can be controlled by triclopyr.
Figure 3. Invasive vines, such as Hedera helix (English ivy) can be controlled via multiple applications of triclopyr.
Where and When Triclopyr is Used Triclopyr is applied in a range of environments, including:
Forestry: To clear invasive species and manage forest regeneration.
Agriculture: To control weeds and shrubs that interfere with crop production.
Aquatic Areas: Formulations that are safe for aquatic environments help manage invasive species near water bodies.
Rights-of-Way: To maintain clear paths and prevent the spread of invasive plants.
Timing of application is crucial. Triclopyr is most effective when applied during the growing season when plants are actively taking up nutrients and can transport the herbicide throughout their system.
Figure 4. Hack and squirt treatments with triclopyr is a common method to control invasive trees. Photo by Lenny Farlee.
Movement in the Plant Triclopyr is absorbed through foliage and roots and is translocated systematically within the plant. Once inside, it moves upward through the xylem and downward through the phloem (ambimobile). This systemic movement allows triclopyr to affect not just the treated areas but also parts of the plant that are not directly sprayed. This attribute makes it effective for managing large, established plants, specifically through hack and squirt treatments (Fig. 4).
MyDNR,Indiana’s Outdoor Newsletter: As a result of Indiana’s positive detection of chronic wasting disease (CWD) in LaGrange County in April, Indiana DNR has restricted moving deer from any CWD Positive Area for rehabilitation purposes.
With the change, an individual who finds an orphaned, sick, or injured deer in a CWD Positive Area may only surrender the deer to a DNR-permitted wild animal rehabilitator that is located within a CWD Positive Area. This restriction is to help minimize the spread of CWD to new parts of the state, as deer can carry this disease without appearing sick.
Currently, there is one CWD Positive Area in Indiana. It includes LaGrange, Steuben, Noble, and DeKalb counties. While no CWD positive deer have been documented in Steuben, Noble, or DeKalb counties, those counties are considered part of the CWD Positive Area because of their proximity to where the state’s first CWD-positive deer was found in LaGrange County.
During their first few weeks of life, fawns often hide by themselves and stay motionless to avoid predators while the mother is looking for food. If you find a fawn alone, you can help it by letting it be, giving it space, and leaving the area. Its mother is likely nearby.
The Indiana Natural Resources Teacher Institute (NRTI) is an annual multi-day conservation education workshop and tour of forest management, forest industry and forestry research in Indiana. The purpose of the institute is to provide an introduction to the impact sustainable forestry has on our state’s environment, economy, and quality of life, and to equip teachers to apply that knowledge in the classroom.
The 5-day workshop advances effective teaching and learning about Indiana’s forest resources and their management. Participants will learn how to approach the teaching of STEM (science, technology, engineering and math) concepts and principles from a natural resource perspective through exposure to professionals, researchers, and industry leaders and hands-on experiences in the field. Participants develop a curriculum project to be implemented with their students, bringing natural resource science and management topics and activities into the classroom.
Natural Resources Teacher Institute participants discuss natural resource issues as part of a Project Learning Tree activity session.
Several partners and many sponsors and supporters facilitate this program. The Indiana DNR Division of Forestry Project Learning Tree Coordinator, Lexi Eiler, serves as the lead on this project, and the Division provides housing for the participants at the Morgan Monroe State Forest Training Center. Donna Rogler, the originator of the Indiana NRTI, Lenny Farlee, Purdue Forestry and Natural Resources Extension Forester, and Mary Cutler, Tippecanoe County Parks and Recreation Naturalist, serve as Instructors/facilitators with Lexi for the week of activities and tours. Each of these individuals is also an alumnus of Purdue Forestry and Natural Resources!
Presenters from several agencies, organizations, and companies assist with field tours and presentations, including a tour and activities on the Hardwood Ecosystem Experiment site at Morgan Monroe State Forest. The connection with this long-term, large-scale research project provides a unique STEM application teachers can take back to their classrooms.
Participants experience forest science, forest management, and forest products processing at the Natural Resources Teacher Institute.
The NRTI program can accommodate up to 16 teachers, with emphasis on primary educators, but welcoming to educators from all ages and backgrounds. Many past participants have called this week the best professional development training they have attended. Some comments from our most recent class in June of 2024:
“It was amazing. I am grateful for the activities and all the fantastic materials provided.”
“I learned so much about forestry and forest ecology. I can’t wait to share my lesson with the students.”
“Loved my time at the Indiana Natural Resources Teacher Institute! I learned so much and can’t wait to share and do activities at school this year.”
Teachers meet with Indiana DNR foresters to learn about forest management techniques on state forests.
Quality of life encompasses individuals’ overall well-being, goals, expectations, standards, and concerns. Various factors shape a person’s perception of quality of life, such as physical and mental health, economic stability, social connections, education, and the environment. Access to healthcare, education, employment opportunities, and recreational facilities significantly influences a person’s ability to meet their needs and achieve their goals (World Health Organization, 2012).
Discover the power of quality of place and placemaking through this new publication by Kara Salazar, who is the Assistant Program Leader for Community Development for Purdue Extension along with being the Sustainable Communities Extension Specialist for Illinois-Indiana Sea Grant. Placemaking is the process of planning, designing, and managing public spaces to enhance quality of life and foster community. Effective placemaking, whether through tactical interventions like pop-up parks or strategic projects that reshape entire neighborhoods, revitalizes communities. By involving residents in the process, we create vibrant spaces that reflect local culture and values. These efforts not only improve quality of life but also attract investment, support local businesses, and promote sustainability.
Figure 1: Drought stress can cause decline and, in some cases, death in trees.
Purdue Landscape Report: With recent rain storms across the state, watering may not be at the forefront of everyone’s minds. But as we head deeper into summer it is food to remember most of Indiana is in a state of abnormal dryness to moderate drought, continuing similar conditions from previous years. With that in mind, we should be thinking about the health of our trees (Fig. 1).
Understanding what drought is and its effects on trees can help to bolster care plans. Drought is an extended time with little to no precipitation and can slow growth, reducing photosynthesis, and depleting energy reserves trees need to survive dormancy in winter. Drought conditions can stress trees, making them susceptible to pests and diseases, reducing their ability to produce defensive chemicals, and in severe situations resulting in death (Fig. 2).
One simple task to protect your trees is watering. This is especially important in young and newly transplanted trees. A good industry guideline is the 5-plus-5 rule.
Figure 2a: Wilting in leaves and dieback in parts of the tree can indicate drought stress.
Figure 2b: Wilting in leaves and dieback in parts of the tree can indicate drought stress.
Apply 5 gallons of water plus 5 gallons for every diameter inch of the trunk. For example, a 4-inch tree would require about 25 gallons of water as needed. A good tactic to reduce water runoff from the hose is to take a large bucket and drill enough small holes to create a slow drip watering system. Also check moisture levels in your soil to see if conditions are dry, moist, or saturated.
Another way to maintain soil moisture is to mulch around the tree. Mulch rings should be at least 3 feet in diameter and 2-3 inches deep with a 2–3-inch space between the base of the trunk and the inner mulch ring. Mulching up to the trunk is called volcano mulching and causes issues like stem girdling root production and decay. Mulching reduces evaporation from the soil and helps maintain moderate soil temperatures. It also reduces competition with surrounding lawn and landscaping plants while protecting the trunk from mechanical damage caused by mowing and lawn care practices.
These little steps can go a long way to protect your trees, extending their life spans and your enjoyment with a healthy canopy. For a more detailed look at drought and trees, please have a look at the Purdue extension store here.
