Purdue Landscape Report: It’s that time of year when we remind everyone to watch for spotted lanternfly (SLF) infestations. Spotted lanternfly is an invasive insect first detected in Pennsylvania in 2014, and has since spread throughout the eastern USA. Its preferred host is the invasive Tree-of-Heaven, but it also feeds on a wide range of important plant species, including grapes, walnuts, maples, and willows.

There are two known populations of SLF in Indiana. The first population was found in 2021 in Switzerland County, and the second population was found in Huntington County in 2022. The Indiana Department of Natural Resources (IDNR), Division of Entomology and Plant Pathology, has launched a delimiting survey throughout the two counties to delimit its range and monitor for activity.

Egg hatch was confirmed in Huntington County and Switzerland County in mid-May at the two known sites. A few adults have been caught about one mile south of the core infestation site in Huntington; however, there are not any new infestations reported as of July 2023. IDNR employees have completed several egg scraping events at the infestation sites, removing over 16,800 egg masses so far this year. That’s over 672,000 eggs!

Finding this invasive insect early is crucial to preventing its spread as long as possible. Currently, SLF nymphs are in their 1^st-3^rd instar, so watch for small, black, white-spotted bugs on Tree-of-Heaven. Later instars are black and red with white spots. The adults are about 1 inch long, with very brightly colored wings. The forewings are light brown with black spots, and the underwings are a striking red and black, with white band in between the red and black. When at rest, the adult SLFs appear light pinkish-grey.

Purdue Landscape Report: I think white pines are beautiful trees, especially at maturity, and they have the added advantage that they are one of the few conifers that don’t try to kill you with their needles. Besides working with the foliage, have you ever had to “rescue” a child who climbed too high in a spike-infested deathtrap of an evergreen? Did you develop the rashes to prove it? Not with a white pine!

My kids haven’t had the chance to climb a mature white pine. Many seem to decline at about 15-20ft. We have been describing this issue as white pine decline, but it isn’t entirely easy to explain. There are a number of factors that influence overall plant health and that can contribute to plant decline, but let’s focus on white pines here. White pine decline is typically attributed to root stress that can be caused by or exacerbated by high soil pH (chemically unavailable nutrients), heavy soil texture (clays), compaction, and excessive soil moisture.

Anything that affects the roots can affect the overall health of the tree, so if the roots are compromised and they cannot uptake water or nutrients, the tree will decline due to lack of nutrients or even lack of water. Needles on an affected tree will turn yellow and eventually brown and fall off prematurely (Figure 1). A symptom of white pine decline includes stems that have shriveled or desiccated bark because roots are not functioning properly cannot pull in enough water (Figure 2).

White-tailed deer are an important part of our Hoosier natural areas and a true conservation success story. Once extirpated from Indiana, deer now thrive in all 92 counties.

Deer can significantly impact the make-up of plants in our natural areas through the plants they eat (referred to as browsing). When the number of deer on the landscape is in balance with the available habitat and deer browsing is at a low intensity, deer can positively impact our forests’ plant diversity. When deer are overabundant, their browsing can impact forests in a variety of negative ways.

5 Steps to address deer impacts to Indiana Woodlands:
Understanding
Understand how deer impact Indiana’s forest ecosystems.

Identify
Identify signs and symptoms of deer impact in your woodland.

Monitor
Monitor how deer are impacting your woodland over time.

Manage
Decide how to manage deer and their impact on your woodland.

Evaluate
Evaluate if the management actions you took reduced deer impact on your woodland.

Check out the new Deer Impact Toolbox website for publications and more details to discover the steps landowners and land managers can take to understand, monitoring, and manage deer impacts to Indiana’s forests.

Wild Bulletin, Indiana Department of Natural Resources (DNR) Fish and Wildlife: Researchers at Purdue University are studying the willingness of hunters and nonhunters to help reduce the spread of chronic wasting disease (CWD) in white-tailed deer. CWD is a fatal neurological disease affecting deer and is caused by an infective protein (prion) that damages the animal’s nervous system. CWD is contagious to deer and can spread through deer-to-deer contact or through contaminated environments. To date, CWD has not been detected in Indiana. No cases of CWD have been recorded in humans.

Researchers at Purdue University are seeking volunteers to participate in this research study. Information collected may help inform Indiana DNR’s response to CWD. Participants will answer online survey questions and use a web app that shows how CWD may spread. The activity and survey questions take about 30 minutes to complete. The study is open to everyone 18 years or older. All that is required to participate is a computer or tablet. Follow this link to Purdue’s website to participate in the study.

Chronic wasting disease (CWD) is a fatal neurological disease affecting white-tailed deer, mule deer, elk, and moose. It is a member of a group of diseases called transmissible spongiform encephalopathies (TSEs), or prion diseases. For more information about this disease visit Indiana Department of Natural Resources – Chronic Wasting Disease (CWD).

For questions about this study, please email the research team at  cwdwebapp@purdue.edu and place in the subject line: “Web App Use and Intention to Reduce Chronic Wasting Disease Spread; Principal Investigator – Dr. Patrick Zollner; IRB Number – IRB-2023-1039″.

In this edition of ID That Tree, we’re going to introduce you to a very rare Indiana shrub that’s a relic of the ice age here, and that is Canada yew. It’s only found in Indiana on very steep slopes, rock faces, and cliffs. It’s an evergreen, so it is coniferous. It’s also very palatable to deer, so deer browse has been very hard on this particular shrub.

If you have any questions regarding wildlife, trees, forest management, wood products, natural resource planning or other natural resource topics, feel free to contact us by using our Ask an Expert web page.

MyDNR, Indiana’s Outdoor Newsletter: As spring has sprung, so has new wildlife. It may be tempting to cuddle cute, young wildlife, but it’s important to always assess the situation from a safe distance.

Young wildlife’s best chance of survival is with their mother, and your support can often unintentionally harm wildlife if that support is not needed. If young wildlife have fallen out of a den or nest, you can return them to their home and then leave the area. It is common for a mother to leave her young for long periods of time to forage for her and her young, so don’t linger around wildlife or their homes too long. Doing this can dissuade a mother from returning or alert predators to the young.

If you’re uncertain whether wildlife need assistance, contact a wildlife rehabilitator before picking up wildlife. If wildlife truly need assistance, they must be turned over to a permitted wildlife rehabilitator within 24 hours. Find a list of permitted wildlife rehabilitators on our website.

To learn more, please visit DNR: Fish & Wildlife Resources.

Spring is almost here and we get to wave goodbye to winter.  Temperatures are rising, the winds are blowing, and trees are waking up—one of the hot topics every spring is planting.  If you missed the chance to get a tree or two (or many more) in the ground this past autumn, then now is the time to start thinking about it again.  Look at your planting spaces to see what kind of tree would do well.  Think about the tree going in the ground now vs 10 years from now, 30 years, or even 50 years.  Will a full-size oak fit in your space or will a smaller redbud work better?  Do you have poorly drained soil where a willow or bald cypress will enjoy the excess water or well-drained soil that an American beech or black gum might fare better? Think about what you might want growing in your portion of the ecosystem.  Are you looking for spring flowers, shade in the summer, color in the fall, or even different bark types and branch architecture for the winter?  Also, once you’ve made your decision and got your new tree make sure you plant it properly to ensure a long happy life and lots of enjoyment.

Don’t forget about the trees you already have in the ground, too.  One simple act that you can do to help them out is to re-mulch your current trees.  Mulching helps to regulate soil moisture and temperature for the roots of your trees.  Grab a rake and work last year’s mulch into the ground a little, then apply enough new mulch to have about a 2–3-inch layer around your tree.  Depending on the size of your tree you might need to have a larger mulch ring, but aim for at least a 3-foot diameter, and DO NOT mulch up to the trunk.  This is volcano mulching and creates an area of decay in the trunk that can lead to failure.  Leave a 2-3-inch ring between the trunk and the mulch.

Observing the colors and patterns of blooming plants is an enjoyable spring activity that reinforces the plant world is becoming active after the long pause of winter. Most mature flowering plants produce some sort of flower structure, but some are more noticeable than others. Some of the earliest among native Indiana trees are red and silver maple, the elms, serviceberry and Ohio buckeye. Some of the showiest blooms are found on redbud, flowering dogwood, tuliptree and magnolias. Keeping a journal of when first blooms are sighted or taking date-stamped photos is a good way to track this sign of spring from year to year and give you a hint of when future blooms may happen.

There is also a substantial show on the forest floor. Early-blooming wildflowers emerge and bloom before trees and shrubs expand leaves, allowing them access to sunlight in early spring. Some plants to look for include spring beauty, trilliums, Dutchman’s’ breeches, and bloodroot. Tree, shrub and plant field guides as well as plant ID apps can help you learn the ID features and life histories of these native plants.

Check out our Purdue Extension YouTube Channel to learn from Lenny Farlee, Extension Forester.  In this Purdue Extension-FNR “YouTube Shorts” video below you will learn about early blooming trees in the spring time.
