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.

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.

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.

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.

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!

The Farmers Helping Hellbenders program is accepting applications for the second round of its Indiana Natural Resources Conservation Service’s Regional Conservation Partnership Program (RCPP) project. The project aims to assist with the conservation/recovery of eastern hellbender salamanders and improvement of aquatic resources in south central Indiana.

Eligible farmers and landowners, who wish to obtain funding to implement practices designed to keep nutrients and soil resources on fields and improve their watersheds, should contact their local NRCS office before May 10 to apply. Financial assistance is available for agricultural lands within the Blue River-Sinking Watershed boundary in Crawford, Floyd, Harrison and Washington counties, where the eastern hellbender can be found and is being actively managed.

Eligible practices for farmers in the project area include conservation cover, grassed waterways, wildlife habitat planting, nutrient management, riparian buffers and many others. Interested farmers and forest landowners who wish to implement conservation practices on their land should discuss their options with their district conservationist. Contact your local district conservationist by visiting Farmers.gov/Service-locator.

While NRCS accepts program applications year-round, Indiana producers and landowners should apply by May 10 to be considered for the current RCPP-Hellbender funding cycle. Applications received after May 10 will automatically be considered during the next funding cycle.

“The Farmers Helping Hellbenders RCPP project enables us to leverage partnerships to make a lasting positive impact on the habitat of the eastern hellbender salamander,” said Damarys Mortenson, state conservationist for the USDA’s NRCS in Indiana. “This project allows Indiana farmers and forestland owners to conserve the vital natural resources on their land while also protecting the habitat for hellbenders and other aquatic animals. It is a win-win.”

The eastern hellbender (Cryptobranchus alleganiensis alleganiensis) is a large, fully aquatic salamander, nicknamed the snot otter, water dog, devil dog, Allegheny alligator and water eel among other things. Their decline statewide has been documented as far back as the early-to-mid 1900s as a result of habitat loss and poor water quality. Hellbenders, which are listed as an endangered species in Indiana, play an important role in aquatic ecosystems and are indicators of clean water. Eastern hellbenders need clean water to survive as they breathe through their skin by absorbing oxygen from the river and stream water in which they live.

Hellbender populations are declining across their range, from Missouri to New York. This decline, which affects the hellbender population in Indiana’s Blue River, is likely caused by human influences such as habitat degradation and destruction. The stream-bottom habitat of hellbenders can be degraded by sediment from eroded banks and fields and destroyed when streams are dammed or dredged. Hellbenders are also captured inadvertently by anglers or purposefully for illegal sale in the pet trade. Finally, emerging diseases may be impacting some populatio​ns of hellbenders. Specifically, the chytrid fungus (Batrachochytrium dendrobatidis) and Ranavirus (family Iridoviridae) are considered to be major threats to the persistence of hellbender populations across their range.

For much of the last 17 years, Dr. Rod Williams and his team have been researching eastern hellbenders, spearheading regional conservation efforts and advancing hellbender captive propagation, or the rearing of this ancient animal in captivity and their eventual return to the wild. The partnership had a major breakthrough over the summer of 2023 with the documentation of a young hellbender salamander in the Blue River while conducting routine surveys. This discovery is significant because over the past three to four decades, only adult hellbenders have been documented in the Blue River. The presence of a young salamander suggests that conservation efforts and rearing programs are accomplishing their goals for the recovery of this endangered species.

The Farmers Helping Hellbenders RCPP project is made possible by $2.7 million in funding from the U.S. Department of Agriculture’s RCPP, Purdue and other partnering organizations. The project is led by Purdue with assistance from 14 collaborating public and private organizations on the state and local level including NRCS. The goal of the project is to improve hellbender habitat in a four-county region in south central Indiana by expanding the use of agricultural conservation practices that lead to decreased sediment in local river systems. The project aims to improve water quality, enhance aquatic habitat, increase aquatic wildlife populations, increase riparian and pollinator habitat and protect karst topography.

Deer are an important part of Indiana woodlands and represent a true conservation success story. Many Hoosiers spent time in the woods pursuing deer during hunting season or marveling at them during walks in their woodlands. But as recently as the 1930s deer were absent from Indiana woodlands. Restocking efforts led by the Indiana Department of Natural Resources helped reestablish deer populations across the state. However, deer populations have rebounded beyond what the land can support in many areas, leading to issues like crop damage, deer-vehicle collisions, and damage to woodlands.

Deer overabundance can pose a threat to the future health of many Indiana woodlands. Deer are considered a “keystone” species, which means their feeding habits (browsing) can shape our woodlands’ look and their plant and wildlife communities. This publication will outline some of the impacts deer can have on Indiana woodlands and what signs and symptoms to look for in your woods.

Learn more about the amount of impact in this new publication:
Low Impact: When deer have little impact on your woodlands, you often see a high diversity of plants. An abundance of preferred species like trillium (picture) can also be a sign of low deer impact.

Moderate Impact: When sprouts of preferred species are “hedged” or kept short by deer browse and browse on less preferred species is noticeable, then deer impact may be moderate.

High Impact: If invasive species like Japanese stiltgrass and garlic mustard are common in your woodland, it may be a sign that deer are overbrowsing native plants.

High Impact: If invasive species like Japanese stiltgrass and garlic mustard are common in your woodland, it may be a sign that deer are overbrowsing native plants.

Very High Impact: Browse lines indicate a severe deer problem and appear when deer browse all plants within their reach (<6 feet).

Deer are an essential part of our ecosystems, but the phenomenon of too many deer should be of concern to forest landowners and the public in general. Deer are a “keystone” species, meaning their browsing can impact forest and wildlife communities. It is clear that when deer become overabundant, their impact on the environment can be problematic. But by understanding the impacts deer have on our woodlands, their food preferences, and how to assess and evaluate impacts in your woodlands, we can begin to address the problems caused by overabundant deer.

Wherever deer exist, they will be impacting the ecosystem through browsing. But at what level is that impact considered harmful? Many ecologists consider deer impact harmful when deer begin to reduce plant diversity in a woodland through browsing. knowing the exact number of deer on a property is difficult to measure and unnecessary. There are relatively easy ways to estimate the number of deer on a property or track trends in population sizes over time. This publication is written to help woodland owners better understand how to monitor deer and their impact.

Monitoring deer impact is done by surveying what deer eat in a forest and how intensively they browse those species. Deer are browsers rather than grazers (like bison and cattle), preferring to eat forbs (broadleaf herbaceous plants), vines, shrubs, and trees rather than grasses. Deer also select specific parts of the plants (e.g., leaves, twigs, and young tender growth).

Monitoring Deer Impact Methods:

• Browse Surveys
• Indicator Plants
• Assessing Vegetation Impacts from Deer
• Ten-Tallest Method
• Twig-Aging
• Oak Sentinel
• Stump Sprouts
