MyDNR, Indiana’s Outdoor Newsletter: Every May, wild turkey chicks (poults) begin to hatch in Indiana, and DNR needs your help counting turkey broods (hens with poults) and hens without poults.
Brood reports have been collected every year since 1993 to calculate the annual Wild Turkey Production index, which informs biologists about population status and guides management decisions for the species. Please share your 2024 observations with us online from July 1 until Aug. 31. Recording observations takes less than five minutes, and no login is required.
In 2023, DNR received more than 2,203 reports across all 92 counties in Indiana, and we’re hoping for even more this year. Our goal is to receive 3,000 total observations with at least 25 per county.
Why count turkeys?
Brood surveys provide useful estimates about annual production by wild turkey hens and the survival of poults (young turkeys) through the summer brood-rearing period. Summer brood survival is generally the primary factor influencing wild turkey population trends. Information on summer brood survival is essential for sound turkey management. Information gathered through the brood survey includes:
- Average brood sizes (hens + poults). For example, in the photo above there is one hen with seven poults, for a brood size of eight.
- Percentage of adult hens with poults.
- Production Index (PI) = total number of poults/total number of adult hens
What is a wild turkey brood?
A wild turkey brood is composed of at least one adult hen with young (poults). As the summer progresses, multiple broods may gather into what is termed a “gang” brood with several adult hens and multiple broods of poults of varied ages. During summer, adult gobblers (male turkeys) play no role in raising a brood and either form small male only “bachelor” flocks or are observed as a single gobbler.
The Indiana Department of Natural Resources – Department of Fish and Wildlife rely on your observations to calculate their Production Index, so every report counts! Indiana DNR appreciates your participation.
Jarred Brooke, extension wildlife specialist with Purdue Forestry & Natural Resources, shares how you can participate in the Indiana Department of Natural Resources’ annual turkey brood survey in a quick video.

Purdue Landscape Report: Recently a homeowner in Hamilton County posted on the Indiana Native Plant Society Facebook page with concerns about aphids, mites, and apple scab in her maple and oak trees. She asked for a second opinion and treatment options for these pests. I reached out to the homeowner and requested permission to collect samples from the trees. Let’s look at what I found (or didn’t find) and discuss when and if these issues should be treated.
Apple Scab on Maples?
First, we can eliminate the concern about apple scab because maple and oak trees are not hosts for this pathogen. Apple scab is caused by the fungus Venturia inaequalis, and hosts include apples, crabapples, hawthorn, mountain ash, firethorn, and loquat. There are other fungal diseases which cause leaf spotting in maples, such as Anthracnose, tar spot, and Phyllosticta leaf spot. To diagnosis these diseases, homeowners can submit a sample to the Purdue Plant & Pest Diagnostic Lab, or hire a certified arborist to assess the tree. However, all these diseases are primarily aesthetic issues. A healthy tree will not die from these pathogens and does not require treatment. You can find more information about maple diseases in this publication: Diseases in Hardwood Tree Plantings. You can also find a previous article on Tar Spot in Maple in the Purdue Landscape Report (Issue 18-12).

Spider Mites
The next pest concern on these trees is spider mites. Out of the dozens of leaves I collected, I found only two immature mites on a couple of maple leaves I examined. This is a very small mite presence, and it is not recommended to treat for spider mites unless the populations threaten the health or appearance of the tree. Limiting pesticide usage will conserve the natural enemies, which are vital to keeping mite populations in check. In fact, improper pesticide applications can kill these important natural enemies and worsen mite infestations.
When do you know if the mite population is large enough to merit intervention? Check your trees for signs of heavy feeding damage, such as leaf stippling (Fig. 1), or dense webbing on the leaves. Mites can also be monitored by placing a sheet of paper (8.5×11”) beneath a branch and striking the limb. Chemical treatments should be considered when you count ≥24 mites per strike. You can find detailed management recommendations and a full list of pesticide options in this Purdue Extension publication: Spider Mites on Ornamentals.

Aphids
The aphids I found on the homeowner’s maple trees are Drepanaphis acerifoliae, or the painted maple aphid (Fig. 2). This species only feeds on maple trees, and is not a threat to the oak tree on this homeowner’s property. Painted maple aphid is a very common aphid in our region. I found only a few aphids on one of the maple trees I sampled, which is not enough to require treatment. In addition, one of the aphids was a “mummy”, or a carcass left behind from a parasitoid wasp. This indicates that natural enemies are already at work managing the aphid population. Aphids may rarely require chemical control if their numbers grow large enough to produce significant amounts of honeydew, which can result in sooty mold outbreaks.
Fig. 3: White-marked tussock moth caterpillar. (Photo: John Obermeyer, Purdue University).
Tussock Moth
The only insect I found on the oak tree was a white-marked tussock moth caterpillar, Orgyia leucostigma (Fig. 3). This is the likely culprit for the minor feeding damage I noticed. These are not significant pests and do not require treatment. Don’t touch them, though! The setae of this caterpillar are irritating and may cause allergic reactions.
Overall, the pests I found were minimal and non-threatening to the trees. It’s normal to find some insect pressure in the landscape. Knowing when and if to treat requires accurate diagnosis and monitoring of pest levels. Check out PurduePlantDoctor.com for an easy-to-use diagnostic aid and treatment recommendations.

The long lifespan of many trees, which could be centuries or even millennia in the case of a few species, is a source of awe and inspiration for many. The bark of trees can often tell some stories about their life and history, if we know how to interpret what we see. Here are a few examples you may run across in Indiana.
Is this tree sick? That may be a natural question to ask when looking at the striking difference in the bark pattern on this white oak. In fact, it is an infection, but not a harmful one to the survival of the tree. This is called smooth patch and is caused by a fungus that infects the outer bark of oak and some other tree species. There are several species of fungus that may cause this appearance, but the most common is Aleurodiscus oaksii. The fungus gradually decomposes the outer layers of bark, producing the flattened and smooth surfaces which contrast with the rough bark that is uninfected. If you look closely during moist periods, you may see the small cup-shaped fruiting bodies of the fungus on the bark. It is not a threat to the health or integrity of the tree as only the outer bark is impacted.
This isn’t the same species of tree, is it? Yes, it is! Bark pattern differences in some species may reflect the growth rate or relative vigor of the tree. These photos show black walnut bark from two very different growing sites. The blocky, alligator-hide bark pattern is often an indication of slow growth and may result from a tree growing on a very difficult site, like the dry hilltop where this tree is located, or severe competition from surrounding trees. The strongly interlacing ridges of the bark in the second photo are from a black walnut growing in a plantation on a creek bench with deep, moist and fertile soils, resulting in more vigorous growth.
What happened here? The pattern in a horizontal line across these trees looks too perfect to be natural, but it was not produced by a human. This is the feeding activity of the yellow-bellied sapsucker, a species of woodpecker that migrates through Indiana. The sapsucker, true to its name, uses its sharp bill to create holes through the bark that ooze sap. The sapsucker feeds on the sap and may also feed on insects drawn to the sap. They tend to create straight lines of holes that leave this diagnostic pattern behind, even long after the birds have ceased their activity. This activity is usually not fatal to the tree, but does cause some damage to the wood beneath the bark, so trees that have been used by sapsuckers may have discolored spots or other blemishes in the wood revealed when processed for wood products. To see images and learn more about sapsuckers visit American Bird Conservatory Website.
Humans also may leave a history of our presence on trees. This American beech tree in a recreation area has recorded the comings and goings of visitors, with some apparent editing as well! I do not endorse this activity as it can be harmful to the tree by introducing avenues for decay and disease, and is generally prohibited on public property. Instead, enjoy reading the nature stories found in bark.

Familiar with surprise lilies? Indiana has a native surprise onion!
Many yards where I grew up in southern Indiana were graced with surprise lilies. These plants grew long narrow leaves in the spring, which faded and died by early summer. After a pause with no evidence of the plant, long stems with pink lily-like flowers emerged, with no leaves to be seen.
Ramps foliage is often found in clusters or patches in early spring. These leaves will die before summer.
While these plants are not a native species, we do have a native with similar habits that is a distant relative of the surprise lily. That plant is ramps, also known as wild leek and a variety of other local names. There are two species of ramps recognized now – the more common broad-leaved ramps, Allium tricoccum, and the narrow-leaved ramps, Allium burdickii. Ramps are related to onions and garlic and have odor and taste reminiscent of those plants. Ramps foliage emerges early in the spring and was one of the earliest green edibles available to First Nations people and early European settlers.
Many communities developed festivals or celebrations centered on the emergence of ramps as a sign of spring and some fresh greens to eat. The bright green leaves emerge before the tree leaves and fade before summer, but by the first half of June expect to see thin stems with a rounded cluster of small white flowers emerge – our surprise onion! It may take a ramps plant seven to ten years from seed to produce a flower, so this is a slow-growing and long-lived forest perennial. The flowers are pollinated by insects and produce round black seeds that may stay on the stalk through winter.
Newly emerged flower stem and buds and the blooming flowers of ramps.
Look for ramps in well-shaded forest areas with moist soils. They have a scattered distribution across Indiana, so you won’t find them in every woodland. The leaves and bulbs are edible, but absolute certainty of ID is essential as there are some toxic plants that look similar. Check ID references and spend some time with experienced foragers before eating any wild plants. The onion/garlic odor of ramps is a good indicator for positive ID.
Since this is a slow growing plant with a limited distribution, over-collection is a threat. A responsible harvesting technique is to harvest one leaf from mature plants, leaving the other leaves and the bulb. If you harvest the whole plant, take less than 5 percent of the plants in a patch, allowing seeding and bulb division to repopulate the area. Seed or bulbs can also be used to plant new patches. So keep you eyes open for our local surprise flowers this June – ramps!

In recognition of Pollinator Week 2024, let’s see what is blooming at Purdue FNR Tippecanoe County property, Martell Forest.
Wild petunia, Ruellia sp, are several species found in woodland and sunny edge habitats. The blooms do look like the familiar garden petunia, but it is a different genus of plants. I caught small insects inside the flower, evidence of its pollinator value, although I have read the individual flowers may only last one day.
I came upon a unique parasitic plant that does not have chlorophyll or true leaves, but obtains its nutrients by parasitizing oak trees. This is American cancer root, Conopholis americana, also called bear corn, because of the similarity of the plant structure to an ear of corn. Although it lacks chlorophyll, it does possess flowers that propagate the plant.
Not far from the cancer root I found fire pink, Silene virginica. This is one flower that would be hard to miss! This is about as red as any native flower encountered in Indiana forests. If you are wondering why pink is in the name instead of red, it is a member of the pink family of plants, which include carnations and a rare prairie relative, royal catchfly. An effort was made a few years ago to make this our state flower, but that has not been acted upon so far.
As I headed downhill I came across Virginia spiderwort, Tradescantia virginiana, with beautiful three-petaled violet to blue flowers clustered at the top of the plant. The flowers typically last only a day, but are rapidly replaced by the numerous buds below the current blooms.
Blue-eyed grass, Sisyrinchium sp. was encountered in a grassy area near a tree plantation. This is not a grass but several species that are members of the iris family. The tiny blooms and narrow leaves blend into the grass background.
Some woody plants are blooming in June as well. This is the bell-shaped flower of American persimmon, Diospyros virginiana. Persimmon trees tend to bear either all male or all female flowers on a single tree, but occasionally a tree will have both. Female flowers are solitary on the stems while male flowers tend to be in small clusters.
The final bloom I have included is rough-leaved dogwood, Cornus drummondii, a shrub relative of the flowering dogwood that provides a white blossom show earlier in the spring. As the name implies, this shrub has leaves with a slightly sandpaper-texture and clusters of small white flowers that are attractive to many pollinators. This blooms later than several other dogwoods, extending the flowering season.
More about Pollinator Week: this an annual celebration in support of pollinator health that was initiated and is managed by Pollinator Partnership. It is a time to raise awareness for pollinators and spread the word about what we can do to protect them. Pollinators include bees, butterflies, beetles, moths, wasps, hummingbirds, bats, flies, beetles, lizards, rodents and more.

Figure 1: Peach trees showing symptoms of peach leaf curl caused by Taphrina
Purdue Landscape Report: The past two months have been relatively wet and cool to warm. This prolonged period of overcast conditions, high humidity, and light to moderate rainfall is perfect for some of our foliar disease issues.
“April flowers bring May Leaf spots” doesn’t have the right ring to it, but we are seeing quite a bit of leaf curl and leaf blister. These are two disease issues caused by Taphrina spp. fungi. Like the common names of their diseases, the symptoms caused by a Taphrina infection include leaf deformation.
Figure 2: Oak leaf blister symptoms ranging from light green early infections, changing to yellow and then becoming necrotic as the season progresses.
In the case of Peach, the leaves turn light yellow, bright pink, or red where tissue puckers and twists leading to curled leaves. In oak, leaves develop localized blisters that are light green early in the season and are easy to miss since the color is not very different from healthy tissue.
However, the blisters will turn brown later in the season which makes them more noticeable. Maples also get a disease caused by Taphrina, but it does not cause as much distortion as it does on oak or peach. Severe maple leaf blister can lead to leaves becoming slightly contorted, but the primary symptom is brown necrotic lesions.
With cool wet weather over an extended period of time, we have been seeing more foliar disease issues than in the last few years.
Figure 3: Symptoms of leaf blister on maple trees.
Since disease problems can take time to develop, Taphrina is likely just the harbinger for some other disease issues we may see in early summer if moderate conditions continue. If the weather dries out as it heats up, it will halt many of these foliar problems in their tracks.

Oak-hickory forests, which are comprised of a variety of different tree species, shrubs, grasses, sedges and wildflowers, as well as wildlife, including songbirds, are important to Indiana’s biodiversity. Learn how you can support oak-hickory ecosystems on your property through a new publication, “Forest Stewardship for Oak-Hickory Ecosystems in Indiana,” produced by Let the Sun Shine In – Indiana.
“The goal of this publication is to provide woodland owners with information about the stewardship practices they can use to sustain and enhance oak-hickory ecosystems on their land,” said co-author Jarred Brooke, Purdue Extension wildlife specialist. “Having this information will help them make informed decisions about how to manage their land to meet their forestry and wildlife objectives.”
The publication discusses various methods landowners can use on their properties, from midstory removal to overstory thinning, prescribed fire, supplemental planting, controlling deer browsing, crop tree release and invasive species control. It also details options for timber harvest, which can be used to regenerate the next generation of a forest. Additional resources from forestry and wildlife professionals as well as other publications discussing current research and management tips also are included in this document.
“Oak ecosystem management is confusing,” said co-author Dan Shaver, state forester for the Indiana Natural Resources Conservation Service. “This publication provides easy to understand basic concepts to help landowners see where their property fits in the oak restoration process. It does not answer all questions or provide all the technical details, but it will help reduce confusion and foster better communication and understanding between landowners and foresters.”
The publication is co-authored by Brooke, Shaver and Kyle Brazil, Central Hardwoods Joint Venture coordinator for the American Bird Conservancy.
“The oak-hickory ecosystem of southern Indiana is incredibly important to birds, other wildlife, and overall biodiversity,” Brazil said.
“Unfortunately, it’s continued persistence isn’t a given. Lack of management, and specifically lack of fire, over the past century has left it in peril. Restoring the oak-hickory ecosystem will require a concerted effort and private landowners are a key part of the solution. This publication is intended to help landowners understand how to manage oak ecosystems on their properties, and give them a roadmap for getting started.”
Woodland owners who are curious about oak restoration or improving their woodlands for songbirds can reach out to their local IDNR forester, the Let the Sun Shine In – Indiana organization or Purdue Extension to find out how to get started.
Let the Sun Shine In – Indiana is a collaboration of several organizations with a shared goal of maintaining oak-hickory ecosystems for the benefit of the people and wildlife of Southern Indiana.
“The LSSI IN collaboration utilizes education and outreach opportunities for landowners, to inform them of the imperiled Oak-Hickory Ecosystem,” explained Judi Brown, coordinator of the Let the Sun Shine In – Indiana. “Part of this outreach includes providing the Oak Hickory Stewardship Guide to landowners. The Stewardship Guide explains common forest management concepts that they can utilize on their properties, and encourages the growth of oak and hickory trees from the acorn or nut into the forest canopy.”
The primary method of distribution of the Stewardship Guide is through the Indiana DNR district foresters, but the guide also is available online. LSSI IN is providing metal gate signs to recognize the stewardship of forest landowners who are actively managing their forest land.
Support for the stewardship guide was provided by the Central Hardwoods Joint Venture, the American Bird Conservancy, the Indiana Department of Natural Resources Division of Forestry, Let the Sun Shine In – Indiana, Purdue Forestry and Natural Resources Extension, the United States Department of Agriculture Natural Resources Conservation Service and the United States Forest Service.
