Purdue Landscape Report: Each spring the PPDL receives several samples of oak trees showing curled, twisted, stunted and/or generally ratty looking leaves. When there are holes in the leaves or leaf edges are missing tissue, we add another symptom name to the mix: tatters.

Distorted new growth and tatters are most common on white oaks and may occasionally show up on red oak, hackberry and other trees. Upon initial inspection the leaves look as if they have been shredded or severely fed upon by insects. However, a closer observation of the leaves will reveal that the leaf tissue has not been removed, but rather, it never developed normally.  We have seen this problem on white oaks for many years in Indiana and it has been reported in other states throughout the Midwest.

Several possible causes for this symptom have been proposed, including poor growing conditions, insect injury, leaf diseases, late spring frost damage and herbicide drift; however, no single factor serves to explain all the cases. In 2020 we saw a distinct link between tattered oak leaves and a late spring frost that year but the connection is not always so clear cut. See PLR article: Oaks Will Persist After Ugly Summer Start.

Researchers have shown that acetochlor and s-metolachlor drift can cause tatters-like symptoms but results were variable, and in some treatments red oaks were more affected than white oaks, contrary to the expected results. In many instances there is no direct link to herbicide drift. We once had samples from a white oak tree that showed symptoms of tatters and leaf curl every year, yet was located in the middle of a heavily forested area miles away from any agricultural fields that might have been a source of herbicide drift. While the exact cause may not be clear, it does appear that conditions that lead to tatters occur while the leaves are still developing.

Agricultue Natural Resources (ANR) Newsletter: Dr. Brian MacGowan is an Extension wildlife specialist and Extension coordinator in the Department of Forestry and Natural Resources (FNR). Brian grew up in rural St. Joseph County and began his career in Extension in 1999.

Part of Brian’s Extension program focuses on professional development in cooperation with many agencies and organizations including the Indiana Chapter of the Wildlife Society, Natural Resources Conservation Service, Indiana Department of Natural Resources, and Fur Takers of America. For example, Brian works with the FTA and DNR to conduct the Professional Trappers College Furbearer Management Short Course held annually since 1980. Nuisance wildlife control operators, conservation officers, wildlife biologists, and trappers attend a week-long workshop.  Almost all participants report improved trapping skills (98%) and that the knowledge gained will help them in their professional career (87%).

Much of his Extension and research has focused on management on public and private woodlands. He served as a co-PI on the Hardwood Ecosystem Experiment (www.heeforeststudy.org) where he studied the effects of timber harvesting on movement and survival of timber rattlesnakes and box turtles. More recently, Brian worked with Dr. Linda Prokopy to evaluate the impact of the Forest Management for the Private Woodland Owner Course and its role in the landowner decision-making process.

Brian also co-instructs (with Dr. Rod Williams) FNR506 Theory and Application of Natural Resources Extension Programming. Since 2012, graduate students per department policy develop a logic model, an Extension plan and an Extension deliverable. In FNR506, students increase their familiarity with natural resource Extension programs, create a logic model based on their own research and Extension interests, develop a plan that outlines extension goals, and increase skills for communicating with non-scientific audiences. To date 270 students have completed the course and produced more than 400 Extension deliverables. A recent academic review showed that “integration of Extension training and activity into the graduate program has been a great success, helping students better understand the role of Extension and outreach into the land grant mission.” Based on data from course evaluations, student interest in Extension has increased 66 percent as a result of the class and 42 percent of students said they would consider a career in Extension.

MacGowan launched the Natural Resources Extension internship program in 2015. This program, which is funded through the Renewable Resources Extension Act (RREA), helps students develop leadership and decision-making skills, increase communication skills, build professional references, and clarify career goals while also enhancing the scope and capacity of the FNR Extension program. Proposals are submitted to a departmental committee, which selects up to three paid internships to be awarded each funding cycle. Eric Norland, the RREA National Program leader, described the internship program as “unique and innovative” and noted “how forward-looking and beneficial (this program is) to both the program and the intern.” Thus far, 21 students have participated in internships, producing 30 videos and 16 publications, helping organize 22 workshops, making 19 presentations, hosting booths at 12 events, and contributing to 15 demonstration areas. A survey following the internships showed a 64 percent increase in a student considering a career in Extension and a 52 percent improvement in ability to speak with non-scientific audiences.

According to Brian, he received some valuable advice early in his career. “One of the best things about working in Extension is you are only limited by time and your imagination. If you have an idea that is good enough, someone will work with you to see it through.”

Agriculture & Natural Resource (ANR) is comprised of many specialists from Purdue Extension and from departments at Purdue. The Purdue Extension Educators serve as research based, unbiased information source for county and state constituents on a variety of topics including: crops, ag business, livestock, natural resource, horticulture, small farms, urban ag, pesticide use, and land conservation.

Wild Bulletin, Indiana Department of Natural Resources (DNR) Fish and Wildlife: The Eastern box turtle (Terrapene carolina) is a species of hinge-shelled turtle that lives on forested land in Indiana. Box turtles are long-lived, slow to mature and have few offspring per year. This, coupled with the high mortality rate of box turtles being hit on roads, has resulted in Eastern box turtles being a species of special concern in Indiana.

Eastern box turtles are listed as a species of special concern in Indiana due to population declines involving habitat loss, road mortality, and collection for pets. If you see one this summer, be sure to keep these guidelines in mind:

• Eastern box turtles may not be collected from the wild; however, if you accidentally catch an Eastern box turtle from Indiana from the wild, please contact the Division of Fish & Wildlife at DFW@dnr.IN.gov; do not release it into the wild. Its chances of survival are low, and it could transmit diseases to other wild Eastern box turtles.
• Sick or injured Eastern box turtles should be left in the wild. Don’t fret—box turtles are surprisingly resilient to damage and disease. If left alone, they will likely heal on their own. If a box turtle appears severely injured, it can be given to a licensed rehabilitator or licensed veterinarian.

If you see a wild Eastern box turtle crossing a busy road, you can pick it up and move it to the other side of the road in the direction it was facing. DNR appreciates your efforts to conserve wildlife.

To identify and learn more about the Eastern box turtle, please visit the DNR: Fish and Wildlife: Eastern Box Turtle website

Illinois-Indiana Sea Grant Newsroom: During large rainstorms, many Illinois residents brace themselves for flooding in their basements, streets and neighborhoods. A new online tool, Illinois Groundwork, provides communities and stormwater professionals with resources on green stormwater infrastructure, which provides a way for rain to be absorbed into soil where it lands.

Green stormwater infrastructure offers a way to enhance traditional or “grey” infrastructure using a rain garden or permeable pavement but this approach doesn’t always work as well as it might. Improving access to, and use of, data, research and other resources can help increase the effectiveness of green infrastructure in addressing stormwater management challenges.

“The University of Illinois not only has relevant research and data across many departments, but also real-world examples of successful green infrastructure, along with other extension and education tools, such as the Red Oak Rain Garden,” said C. Eliana Brown, University of Illinois Extension stormwater specialist. “This new tool brings these resources together, providing a robust platform to access green infrastructure knowledge.”

Illinois-Indiana Sea Grant Newsroom: Last May, Illinois-Indiana Sea Grant (IISG) launched its third buoy in southern Lake Michigan—this one based in the busy waters off Navy Pier. This new buoy with its flow of in-the-moment data is helping the National Weather Service (NWS) Chicago develop more accurate forecasts and warnings, especially related to nearshore wave heights and wind speeds.

This third buoy, known affectionately as Chuoy, joins IISG buoys in the nearshore waters of Michigan City, Indiana and Wilmette, Illinois. Together, these three, along with two University of Illinois buoys closer to the Wisconsin border, paint a comprehensive picture of coastal lake conditions in the two states. In addition to meteorologists, the data is used by scientists, boaters, anglers and beach goers.

“Information from these buoys allows recreational water users to make better informed decisions when it comes to safety,” said Ben Szczygiel, IISG buoy specialist. “The data allows people to plan for current conditions and avoid the water when there are increased safety concerns.”

MyDNR, Indiana’s Outdoor Newsletter: The Indiana Natural Resources Foundation, in partnership with the Division of Forestry, is planning another busy year for the Indiana Tree Project. In 2022, more than 11,000 trees were added to Indiana’s public lands through Indiana Tree Project plantings, and this year is expected to be another successful year.

Through a partnership with the Division of Forestry, we are helping Indiana’s forests grow, one tree at a time, with the Indiana Tree Project. Healthy forests in Indiana promote wildlife habitats, clean air and an abundance of outdoor recreation opportunities. It is estimated that 85 percent of Indiana was once forested. Today, only 19 percent of the state is forested. The Indiana Tree Project is much more than just planting trees. Through this project we are adding new acreage to Indiana’s State Forests and we’re trying to add 1,000 acres of new forested land.

When you support the Indiana Tree Project, we provide you with an official tree certificate to demonstrate your support for the smart management of Hoosier forests. It includes the coordinates for the acre on which your tree is, or will be, planted.

MyDNR, Indiana’s Outdoor Newsletter: During the spring and summer please let us know if you think you may have seen spotted lanternfly by contacting us at 866-NO-EXOTIC (866-663-9684), or by email at DEPP@dnr.IN.gov. Please be sure to provide your contact information and detailed information about the location. Early detection is crucial to successful spotted lanternfly management efforts.

Spotted lanternfly is a major pest of concern across most of the United States. This insect is native to China and parts of India, Vietnam, Japan, and Taiwan. It was first identified as an invasive species in 2004 in South Korea and is now a major pest there. Spotted lanternfly was first detected in the United States in Pennsylvania in 2014.

In July 2021, a population of spotted lanternfly (Lycorma delicatula) was identified in Indiana in Switzerland County, near the Ohio River. A second population was found in Huntington, Indiana in July 2022. DEPP and USDA continue to conduct surveys to ascertain the extent and source of these infestations as well as determine what management strategies will be implemented.
