Do you have a favorite place, species, landscape or natural phenomenon in Indiana? Share it with Dr. Clement Bataille through this Qualtrics survey and it may become part of the new Indiana Natural Resources and Wonders course in spring 2027.

The course will offer a broad survey of Indiana’s natural history and remarkable natural resources, highlighted by a series of case studies ranging from mastodons and glacial lakes to prairies, insect migration, freshwater mussels and more. The course will introduce the natural systems that make Indiana one of the most productive and biologically distinctive landscapes in the United States, from rocks to soils and water, to forests, wildlife and climate.

To flesh out course content and topics for conversation, Bataille is inviting all Indiana residents, FNR alumni, natural resource professionals and other members of the community to share a photo or short story about an Indiana natural resource, place or experience in the state that they find particularly meaningful, remarkable or inspiring.

The deadline for submissions is Nov. 30, 2026.

The Indiana Natural Resources and Wonders course will begin with a look at the Paleozoic bedrock beneath the state and the glacial ice that reworked its surface, then examine the soils that resulted and explain why Indiana supports both exceptional forests and exceptional agriculture. Students will then explore the hydrosphere, working through rivers, lakes, wetlands and groundwater along with their biodiversity and their long history of human interactions. From there the course turns to the prairies and forests of Indiana, then to wildlife and biodiversity, from resident species like white-tailed deer that are actively managed to migratory birds and insects. The course also will investigate how observed and projected climate change might reshape natural resources across Indiana and the conservation and management solutions needed to face this change.

Beauty is not necessarily an overriding virtue for the winged burning bush (Euonymus alatus). Also called winged euonymus or simply burning bush, it has gorgeous red fall color and has been a popular choice for landscapes since the late 1800s. However, we’ve known since the 1970s that this beautiful plant has demonstrated invasiveness in natural areas.

Purdue experts authored an Extension publication entitled “Invasive Plant Series: Winged Burning Bush.” Much of this article will highlight excerpts from the publication.

“Winged burning bush can tolerate a wide range of sites and soil conditions,” they said. “It grows in full sun and tolerates full shade under a forest canopy.” Its fruits are eaten by birds and dispersed elsewhere, such as from landscapes to neighboring natural areas. It can form dense undergrowth in woodlands.
As the name implies, twigs and branches of this shrub have corky ridges or “wings.” Leaves are arranged oppositely on twigs, from ¾ to 2 inches long, and tapering at each end. “Leaves turn a vibrant red in autumn for plants in full sunlight but may be shades of magenta or pink in shaded areas,” they said. A single plant can produce fertile seed.

Besides this invasive plant, Indiana has three native euonymus species that could be confused with their invasive relative. The most common is eastern burning bush or wahoo (Euonymus atropurpureus), which is a large shrub to the size of a small tree. Running euonymus or running strawberry bush (Euonymus obovatus) is a perennial groundcover that may only get from one foot to a few feet tall. Strawberry bush or brook euonymus (Euonymus americanus) is a small shrub found primarily in southern Indiana.

“The ability of winged burning bush to spread via seeds dispersed by birds, survive and produce seed in shaded environments, and gradually increase density and distribution in forests presents a threat to the native diversity and productivity of natural habitats in Indiana,” they said. “Besides seed production, winged burning bush stands can increase in density by layering, where a branch comes in contact with the soil and roots.” They said research has shown that high deer population levels promote the establishment and spread of some invasive plant species, including winged burning bush. Deer preferentially browse on desirable native plants while avoiding winged burning bush.

The authors urge prevention as the first step in preventing the spread of burning bush. This strategy is simple: don’t plant burning bush.

The authors discuss various control methods for burning bush in natural areas, including manual and mechanical methods, prescribed fire, and chemical controls. See the publication for details. Find it at the Purdue Education Store.

If you have burning bush in your landscape, please consider removing it and replacing it with a native alternative, like wahoo (previously mentioned), chokeberry, common ninebark, American cranberry bush viburnum, fragrant sumac, or winterberry. Research your potential replacement to ensure it is suited to your landscape location (size, site conditions, etc.).

Several things come into play when it comes to determining the colors that we find on leaves of our trees. As our days get shorter and our nights get longer there is a chemical change that happens in the tree. In this video Lenny Farlee talks about the several pigments that are found in trees and what changes from summer to fall that brings us the bright colors on leaves.

Explore IndyStar Story Behind Our Fall Colors
For more on what determines the specific colors our leaves turn and how weather and other factors influence the fall display check out this recent IndyStar article: What determines what color leaves turn in the fall? The story features insights from Lenny Farlee, Purdue Extension forester, who shares his expertise on the science and beauty behind Indiana’s fall foliage.

As the crisp autumn air settles in and campfires become a seasonal staple, October brings an important reminder: your firewood choices matter. That’s why October is officially Firewood Month, a nationwide campaign to raise awareness about the risks of moving firewood and the spread of invasive forest pests.

Why “Don’t Move Firewood” Matters
Transporting firewood, even just a few miles, can unintentionally spread destructive pests like emerald ash borer, Asian longhorned beetle and spongy moth. These invaders often hide inside or on firewood, threatening Indiana’s forests, parks and urban trees.

The Don’t Move Firewood website offers excellent resources to help you make informed choices. Whether you’re heating a cabin, heading out to hunt, or planning a backyard bonfire, they recommend:

• Buying firewood where you’ll burn it
• Choosing certified heat-treated wood
• Gathering wood on-site when permitted

You can also explore their Firewood Month Toolkit, maps of regulations and a webinar series designed for professionals and outdoor enthusiasts alike.

While October is Firewood Month, the risk of spreading invasive pests lasts well beyond the fall. Many forest pests remain a threat throughout the year. Adults may still be visible until the first hard freeze, and egg masses can be observed from now through June. The spotted lanternfly females lay egg masses in late summer through early winter, often peaking in October. These masses can survive through winter and hatch in the spring. Learn more about the Spotted Lanternfly from the Indiana Department of Natural Resources. This is why it’s important to practice safe firewood habits year-round.

Spotlight on ReportINvasive
Check out the latest post on the ReportINvasive Facebook which reinforces the importance of Firewood Month. ReportINvasive is a trusted source for updates on invasive species in Indiana, and their social media outreach is a great way to stay informed and engaged. Give the Facebook page a LIKE and FOLLOW for future webinars and workshops.

Concerned About Insects? Purdue Extension Entomology Can Help
If you suspect insect damage or want to learn more about forest pests, the Purdue Extension Entomology team is an outstanding resource. Their experts provide science-based guidance on insect identification, management strategies, and outreach materials to help protect Indiana’s ecosystems.

Let’s work together to keep Indiana’s forests healthy and resilient. This October, make the smart choice—don’t move firewood!

Following a recent tornado in Monroe County, an Indiana homeowner noticed something remarkable among the storm damage. More than 30 trees, including walnut and butternut, were either uprooted or snapped. Yet several mature shagbark hickory trees stood largely untouched amid the destruction.

This observation prompted an interesting question: Is there something about shagbark hickory trees that makes them more resistant to tornadoes and high winds than other hardwood trees?

Answer: While every storm is different and no tree species is completely tornado-proof, the observation aligns with what foresters and arborists know about hickory wood.

Shagbark, along with other hickory species, is among one of the stronger trees native to Indiana. Because of its strength and shock-absorbency quality, hickory is a prime choice for tool handles and baseball bats as well as solid wood furniture and flooring.

Shagbark hickory (Carya ovata) is famous for more than its distinctive peeling bark. The wood itself possesses exceptional mechanical properties.

Hickory wood combines:

• High strength
• Notable elasticity
• Superior shock resistance
• High density

Together, these properties give hickory exceptional toughness – the capacity to absorb and redistribute energy before fracturing. This means its stems and branches may bend under wind loading rather than fail as abruptly as wood with lower toughness.

For that reason, hickory has long been valued for products subjected to repeated impacts. Traditional axe and sledgehammer handles, drumsticks, and baseball bats have often been made from hickory because it can absorb shock and withstand repeated bending stresses without breaking as readily as many other hardwoods.

Healthy Trees:
Healthy trees with vigorous growth and little decay generally withstand stress better than weakened trees. This is one reason why it is important to evaluate your trees before severe weather and storm season arrives. Identifying structural defects, dead branches, decay, or other potential hazards early can help reduce the risk of tree failure during high wind events. The following Purdue Extension-Forestry and Natural Resources (FNR) blog articles can help you assess your trees and recognize common warning signs:

Jarred Brooke, Extension wildlife specialist, was honored with a Career Achievement Award at the Fire in Eastern Oak Forests Conference in June.

In addition to his extension work with wildlife, Brooke has been deeply involved in prescribed fire, serving as chair of the Indiana Prescribed Fire Council since 2018, working to implement prescribed fire policy in Indiana, and organizing more than 30 Learn-N-Burn and Prescribed Fire field days and workshops that provide landowners and professionals with practical experience in fire safety, timing, and ecological benefits. Jarred has also co-instructed the undergraduate FNR-333 Applied Fire Ecology course since 2019. He was instrumental in securing funding from the Sam Shine Foundation to hire Danielle Howard, the recently hired Extension prescribed fire specialist.

Brooke also was one of three main instructors and organizers of the Indiana Land Stewardship Leadership Academy, which graduated its first class this spring. He was honored in 2021 with the Early Career Award from the Purdue Cooperative Extension Specialists’ Association and PK-12 Council’s Staff Excellence Award for his work with youth audiences, expanding their interest in and preparation for careers in natural resource sciences.

“It’s an honor to have been given the Career Achievement Award from the Fire in Eastern Oak Forests Conference,” Brooke said. “Since I don’t have enough gray hair for a career achievement award, we’ll just call it an early-career award. I have enjoyed all the prescribed fire work I’ve been able to do through my Extension role at Purdue, but this award would not have been possible without all the partners I work with on fire. From leading Learn-N-Burns and serving on the Indiana Prescribed Fire Council board to working

on prescribed fire policy in the Hoosier state, it’s been a collaborative journey – and I’m looking forward to more in the future! Special thanks to Allen Pursell for presenting me with the award.”

At the awards presentation, Pursell, director of forest programs for the Sam Shine Foundation, Inc., said:

“Jarred served as president of the Indiana Prescribed Fire Council from its inception in 2016 through 2025, and remains active. Jarred was known for great ideas, energy, and leadership skills. One of the board members told me that Jarred really held the council together, especially during Covid, when it would have been easy for it to wither.

“As part of his accomplishments there:

• He spearheaded getting the Indiana Prescribed Fire Council incorporated as a non-profit entity.
• He was the key person shepherding the entire process that resulted in the new Indiana Prescribed Fire Law. Many people were involved in key roles, but Jarred made it come together.
• More recently, Jarred identified funds so that Purdue University could hire a Prescribed Fire Extension Specialist who will help to form and support Prescribed Burn Associations, Support the Certified Prescribed Burn Manager program, and Conduct prescribed fire outreach to local communities.

• In addition to these, Jarred has conducted many “learn and burn” courses for students and citizens who are interested in prescribed fire. He is a leader among his peers and an untiring advocate for prescribed fire in Indiana.

“For these accomplishments and many others, we are pleased to present Jarred Brooke with this career award.”

The Eastern Oak Forests Conference achievement awards are meant to recognize any significant contributions ranging from science, management, education and outreach, or training. Awards for the conference began during the 2019 conference playing and have ranged from one to six awardees per conference. Awardees are nominated by conference steering committee members.

Purdue Landscape Report: Espalier is a pruning and training technique that shapes a tree or shrub to grow in a flat, usually two-dimensional form, often against a wall, fence, or trellis. Rather than allowing branches to grow in every direction, espalier uses careful cutting and tying to guide stems into a planned pattern. The result can be both practical and beautiful, turning a fruit tree or ornamental plant into a living architectural feature.

This method has been used for centuries, especially in places where gardeners wanted to maximize growing space or use walls to create a

warmer microclimate. Espalier is especially popular with fruit trees such as apples, pears, and sometimes figs or stone fruits, because the open structure can improve light penetration and make harvesting easier. It is also valued in formal gardens and small urban spaces where a full-sized tree would be too large or unruly.

One of the biggest advantages of espalier is efficient use of space. A tree trained flat can fit into narrow courtyards, along property lines, or against sunny walls where space is limited. It can also make maintenance easier, since pruning, spraying, thinning, and harvesting are often more accessible than in a dense, free-growing tree. In fruit production, better sunlight and air circulation can improve fruit quality and reduce some disease problems. For many gardeners, espalier is also appealing because it adds a strong visual design element to the landscape.

Espalier does have challenges. It requires patience, regular attention, and a willingness to prune frequently during the training phase. The technique is not ideal for every species, and success depends on choosing a plant that responds well to bending and cutting. If neglected, an espaliered tree can lose its shape quickly and become difficult to correct. It also demands a level of planning that is greater than ordinary pruning, since the final form must be imagined and maintained over time.

The technique is most commonly associated with Europe, especially France, Italy, and England, where it has long been used in formal gardens, orchards, and along estate walls. Today it is also popular in North America among home gardeners, landscape designers, and urban fruit growers who want to combine productivity with ornament. While espalier is less about a single geographic region than pollarding, it remains especially visible in European garden traditions and in places where intensive use of limited space matters.

Espalier is both practical and artistic. It can help gardeners grow more in less space while creating a distinctive look that feels deliberate and refined. For the right plant and the right site, it is a pruning style that blends horticulture with design.

Purdue Landscape Report: Pollarding is a tree pruning method in which the upper branches of a tree are cut back to the same points on a regular schedule, creating a framework of knobby growth points from which new shoots emerge. The practice has been used for centuries and is especially common in landscapes where trees must be kept at a controlled height or width. Pollarding is not the same as topping, which is generally considered harmful because it removes branches without a long-term management plan. Instead, pollarding is a deliberate, repeated technique that can shape a tree into a compact, manageable form.

One of the main advantages of pollarding is size control. In urban areas, along streets, and near buildings or utility lines, trees often need to fit within tight spaces. Pollarding can reduce conflicts with overhead wires, streetlights, sidewalks, and traffic while still allowing a tree to remain in place. It can also reduce shade, which may be useful in courtyards, parking areas, and other sites where too much canopy cover is a problem. Some trees also respond by producing dense, attractive new growth, which can give them a distinctive architectural look.

Pollarding may also extend the usable life of certain trees when it is started early and maintained properly. Because the tree is kept smaller and more compact, it may be less likely to fail under wind or storm stress than a large tree with heavy limbs. In some settings, the regular cutting of new shoots can even provide a source of small-diameter wood or fodder, which helps explain why pollarding developed historically as a practical land-management method.

That said, pollarding has real drawbacks. It must be done correctly and consistently; if a tree is pollarded at the wrong age, on the wrong species, or after long neglect, the result can be stress, decay, weak regrowth, or structural problems. Not all trees tolerate the practice well, and some may decline if pollarded too aggressively. Pollarding also creates a very artificial appearance, which some people dislike. A freshly pollarded tree can look bare or severe for a time, and the repeated cuts require ongoing maintenance.

Pollarding is most strongly associated with Europe, especially Britain, France, the Netherlands, Italy, and parts of Spain, where it has a long history in both rural and urban landscapes. Today, it is still widely seen in European cities and towns, particularly on street trees and in managed public spaces. It also appears in some parts of North America, but it remains much more culturally visible and historically rooted in Europe. In many places, it is valued both for its practical function and for the distinctive form it creates over time.

Used thoughtfully, pollarding is a useful tool rather than a universal solution. It works best when matched to the right species, the right site, and a long-term maintenance plan. For the right tree in the right place, it can be both functional and visually striking.

Entomology Weekly Review: Purdue Forestry & Natural Resources (FNR) Extension would like to share a timely update from the Indiana Department of Natural Resources – Division of Entomology newsletter regarding a wood-boring insect that may be encountered in hardwood logs across the state. Will Drews, Entomology staff member located in south-central Indiana (Bloomington area), recently reported activity from one of the more common round-headed borer pests found in hardwood logs: the flat-faced longhorn beetle, Graphisurus fasciatus. Will shares in the Entomology Weekly Review how to identify the borer, their habitat and if we need to be concerned.

What to Look For
On the wing recently is one of the more common round-headed borer pests I find in hardwood logs, and that is the flat-faced longhorn beetle without a common name: Graphisurus fasciatus (Photos 2 – 5).  This longhorn beetle (in the family Cerambycidae) is quite large as far as longhorn beetles go, reaching up to 0.6 inches in length, and features two long antennae (aka “horns”) characteristic of most of its family (Photo 3).

Host Trees and Habitat
As a larva, Graphisurus fasciatus feeds on a variety of hardwoods and is reported to feed on pine trees as well. I generally find G. fasciatus larvae feeding between
the bark and sapwood of black walnut (Juglans nigra), white oak (Quercus alba ) and red oak (Quercus rubra) logs (Photo 6).

Identification Tips
There are several ways to differentiate this species from the less common but closely related Graphisurus despectus, but one of the surest ways is to examine the scutellum (aka the small shield-like plate at the top/between the elytra [wing covers]). In G. fasciatus, the scutellum has two small whitish patches of hair, not present on G. despectus (Photo 7). Another diagnostic characteristic of G. fasciatus is that it has elytra with emarginate (or notched) tips (Photo 8).

Should You Be Concerned?
This species can be alarming by its noticeable size and relative abundance but is not necessarily a major pest of concern as it does not usually bore into the sapwood and cause defects to the wood.

Stay Informed
FNR Extension encourages landowners and natural resource professionals to remain observant when working with hardwood logs and report unusual insect activity when found.

To stay up to date on forest health and insect alerts, consider subscribing to the  Indiana Department of Natural Resources – Entomology Weekly Review for regular updates on insects affecting Indiana’s forests and natural areas.
