Purdue Landscape Report: Spotted lanternfly (SLF) (Lycorma delicatula), a serious invasive plant pest, has been reported to be in Indiana. This federally regulated invasive species harms plants by slowing their growth and reducing fruit production, especially in vineyards and orchards. Finding this pest this far west of its previously known distribution makes it possible for SLF to be anywhere in Indiana. Knowing where this pest is located can help us respond more effectively to this pest.
Right now, the Indiana DNR is asking for all citizens to keep an eye out for spotted lanternfly. The bright color of late stage immatures and adults are easily recognized at this time of the year. Anyone who spots signs of the spotted lanternfly should contact the Indiana Division of Entomology and Plant Pathology (DEPP) by calling 866-NO EXOTIC (866-663-9684) or send an email (with a photo of the insect if possible) to DEPP@dnr.IN.gov. For more information about this or other invasive pests see the following link.
What is Spotted Lanternfly?
Spotted lanternfly is a planthopper that originated in Asia. It was first discovered in the United States in Pennsylvania in 2014. The Pennsylvania Department of Agriculture was unable to limit the spread of this pest because it is an effective hitchhiker and is often spread unknowingly by humans.
Adult spotted lanternfly has two sets of wings, and the underwing has a very distinct red color with spots on the outer wings. The fourth instar of the insect is bright red with black and white markings. The egg masses of this invasive insect look like mud and they can be spread by vehicle transport including recreational vehicles, cargo carriers (truck transport) and freight trains. They can also be spread through trade materials sold in infested areas that are shipped out of state including nursery stock, outdoor furniture, lumber, etc. Anyone receiving goods from the east coast should inspect for signs of the insect, especially if the commodity is to be kept outdoors.

Purdue Landscape Report: When was the last time you really looked at your trees? It’s all too easy to just enjoy their cool shade and the sound of their leaves, but if you don’t know what to look for you could miss deadly diseases or dastardly demons lurking in their leaves and branches. A quick check can help you stop a problem before it kills your tree or your local forest!
National Tree Check Month is the perfect time to make sure your tree is in tip-top shape! Our checklist will help you spot early warning signs of native pests and pathogens and invasive pests like Asian longhorned beetle, spotted lanternfly, and sudden oak death. You can stop invasive pests in their tracks by reporting them if you see them.
Is your tree healthy and normal?
Start by making sure you know the type of tree you have. Is it a deciduous tree like an oak or maple? Or is it an evergreen that like a spruce or a pine? Don’t worry about exactly what species it is. It’s enough for you to have a general sense of what the tree should look like when it’s healthy.
Check the leaves
Check the trunk and branches
Now what? If you answered YES to any of the questions above, there’s a good chance something is wrong. To decide if and how you should treat or report the problem, you’ll need to have a tentative diagnosis. Luckily, there are many ways to get one!
Know the tree species? Use the Purdue Tree Doctor to get a diagnosis and a recommendation on whether treating or reporting is needed. This app allows you to flip through photos of problem plagued leaves, branches and trunks to help you rapidly identify the problem. If you have an invasive pest, it will guide you how to report it.
Don’t know the tree species and still need help? Reach out to local experts. We’re happy to help!

Forest management in the eastern United States is faced with many modern challenges. Professional foresters have an innovative set of management options for the maintenance of healthy forest ecosystems. But some options raise public objections when applied to public lands (e.g., types of timber harvest, prescribed fire) and the effects of some management options on forests and their native inhabitants are poorly understood. Moreover, forest lands in the eastern and Midwestern United States primarily are in small privately-owned parcels that change ownership relatively frequently. These lands are often managed for short-term financial gains rather than long-term sustainability.
As populations of some forest organisms decline, restrictions on landowners may increase because species become classified as endangered or threatened (e.g., the Indiana bat), while increasing populations of other species (white-tailed deer, invasive plants) create economic and ecological challenges. These problems are compounded by the lack of scientifically rigorous research on the overall impacts of forest management on the effected ecosystems and their components. To address this set of issues, the Hardwood Ecosystem Experiment (HEE), a long-term, large-scale experimental study of forest management and its impacts, was initiated in 2006.
Many of Indiana’s forests have been dominated by oak and hickory trees for thousands of years. The historical conditions that shaped today’s forests have changed, altering forest composition and leading land managers to wonder what can be done to maintain oak and hickory forests for the future. The Hardwood Ecosystem Experiment: 2006-2016 provides an overview of findings for the first 10 years of the HEE, 100 year project.
To learn more about this 100 year forest management plan and see its impacts, check out the Hardwood Ecosystem Experiment website.

Having raccoon, groundhog, or other bothersome wildlife problems? Thinking about setting traps to catch these animals? There is much to consider when using traps. Take a look at the latest publication for best results.
Wildlife specialists Brian MacGowan and Rick Shadel have collaborated to bring you this new publication: Considerations for Trapping Nuisance Wildlife with Box Traps.
Homeowners commonly set traps to capture and remove wildlife from their home or yard. Setting a box trap improperly can decrease their effectiveness and even lead to safety risks to both people and wildlife. The purpose of this publication is to 1) outline the legal and ethical factors homeowners should consider before setting a trap, 2) review the basic procedure for effectively trapping wildlife, and 3) help you to determine the fate of the captured animal.
If you have a serious, dangerous, or a nuisance wildlife issue, you may want to consider hiring a professional. Consider reading this publication before deciding whether or not you need to hire a professional: Selecting a Nuisance Wildlife Control Professional.

Article published: Morning Ag Clips: Citizen Scientists — Report Invasive Species
Written by: Emma Ea Ambrose, Agricultural Communication Service, Purdue University
National Invasive Species Awareness Week kicked off on Feb. 25 (Monday) and runs through March 3 (Sunday).
The campaign is designed to enhance awareness about invasive species and encourage reporting of invasive species from what Purdue University entomology professor Cliff Sadof calls “citizen scientists.” This includes people who spend time professionally or recreationally in the outdoors and is interested in learning about invasive species. A major tool in the fight against these species is the Report Invasive website, hosted by Purdue College of Agriculture and the Indiana Invasive Species Council. The website includes several ways that people can report invasive species, including a smartphone app from the Great Lakes Early Detection Network.
“There are not that many specialists and experts covering the state,” Sadof said. “When there are concerned citizens reporting, however, we have many more eyes and a better chance of detecting and eradicating a harmful species early.”
Please report any invasive species you come across including insects, plants, and animals to Report Invasive Species.

As climate change and habitat destruction become more of a public concern, the popularity the Animal Planet channel has grown as it seeks to educate viewers about the importance of wildlife preservation and the role human interaction has in these habitats. The network now shows a variety of programming ranging from survival shows to conservation and management of wildlife.
Wildlife shows such as ‘The Crocodile Hunter’, ‘River Monsters’, and ‘The Zoo’ emphasize the efforts of biologists, wildlife researchers, and zookeepers involved with wildlife to the general public. More recent shows such as ‘Lone Starr Law’, ‘North Wood Law’, and ‘Rugged Justice’ show how Fish and Wildlife Game Wardens enforce laws (Federal and State) that protect aquatic, avian and terrestrial life.
The National Park Service mission, as directed by the Organic Act of 1916 is “to conserve the scenery, natural and historic objects, and the wildlife therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations.” Wildlife biologists/researchers and park managers require extensive information on the species within a habitat to best protect and conserve native wildlife. These data can then be used by managers to devise and implement strategies that will provide future protection of wildlife from invasive species as well as human-induced stresses (air and water pollution, deforestation and habitat encroachment).
Several methods for monitoring wildlife are employed by wildlife researchers in order to track animal movements and determine home range size within a particular habitat. For herding populations such as elk and deer, aircraft are used. For solitary animals such as bears and mountain lions, radio-telemetry can be used. A remote/trail camera (the most non-invasive tool for wildlife research) allows wildlife researchers to observe these animals in their natural habitat without disturbing them (our presence modifies the behavior of many species), answering the question of “What’s present when we are not there?” As an efficient and cost-effective way to supplement or replace human observers, remote wildlife viewing camera systems are used worldwide to document species presence and distribution addressing a variety of research and management objectives.
One of the most promising times to observe trail cameras is during the spring when many species have their young. A popular viewing request is to watch raptors, hummingbirds, and songbirds raise their young. Indiana and other nearby states have erected several high-definition cameras that allow real-time observations of some of these and other native species.
These cameras typically run 24/7 and allow viewers to see eggs hatching and parents feeding their young. There are also cameras within zoos nationwide, along waterways, and in fields to catch glimpses of other animals. If you are unable to venture into the field and want close-up views of some of our majestic wildlife. A host of different online sources are available for you to view animals in their natural habitat or those animals that may be housed in sanctuaries or zoos. Check out the cameras below to start or go to https://explore.org for more great species to watch.
As technology improves and operation costs decrease, use of trail cameras is becoming an increasingly more valuable tool as it gives a more definitive view of the pressures (both natural and human-induced) that wildlife face in their natural habitat. Information collected about wildlife in parks can be as simple as confirmation of the presence of a species or as detailed as the average number of young produced per female per year. If you come across a trail camera in a park or anywhere on public land, recognize the potential for sensitive wildlife habitat in the area and leave them undisturbed.

Zoos Work with Purdue University for Hellbender Conservation Efforts, Got Nature?, Purdue FNR-Extension

The Hellbender salamander is North America’s largest salamander. It is fully aquatic, living its entire life in rivers and streams throughout the midwest and southeast. Hellbenders require cool, clean rivers and streams with rocky substrates to thrive and reproduce. Unfortunately, over the past several decades the species has declined or disappeared from many of these areas. In Indiana, the species can only be found in the Blue River in south-central Indiana where there remains only a very small, geriatric population incapable of sustaining itself. In order to save the species in the state, Purdue University and its many partners have joined together to reverse the decline.
On November 1st and 2nd of this year, Purdue FNR’s Williams lab released 80, 4-year old Hellbenders into a site chosen as the best Hellbender habitat in the Blue River. Members from Purdue University, Mesker Park Zoo and Botanic Garden, Columbian Park Zoo, Fort Wayne Children’s Zoo, Indianapolis Zoo, the Indiana Department of Natural Resources, the Indiana Department of Environmental Management, Duke Energy, and more all helped in the task of releasing the individuals into their new homes.
The chosen Hellbenders had been raised in captivity at Purdue University. Unfortunately, captive-raised animals are often times not equipped with the necessary set of skills to survive life outside of an aquarium. However, these were not all aquarium-raised individuals more akin to pets than wild animals. Forty of the individuals were raised in specially designed tanks called raceways that incorporated water flow to mimic that found in a natural river setting. The remaining forty individuals were raised in standard, low-flow conditions. The idea behind raising the animals in these differing conditions is to compare whether or not the individuals raised in conditions that are more natural (i.e., higher flow rates) will be better able to survive the varying water levels they will encounter in the wild than those that are raised without flow.
In order to document success, all 80 Hellbenders were implanted with radio-transmitters. These transmitters emit a signal that allows biologists to detect them with antennae and locate the exact location an individual is hiding. For the next six to ten months, through rain, snow, and shine, Purdue biologists will follow these animals to document their behavior, habitat preferences, and whether or not they survive life in the wild.
The outcomes of this study could help solve two major problems facing Hellbender conservation. The first is that the addition of Hellbenders into the system could help spur natural reproduction and help to start stabilizing the system. This small step is important towards our eventual goal of repopulating the Blue River and other former Hellbender streams. The second problem this study will hopefully address is the issue of poor survival of captive-reared animals when released into the wild. If we find that raising animals in more natural conditions improves survival over those raised in the more common no-flow conditions, this technique could be easily adopted at captive-rearing facilities throughout the nation and help increase the overall success of Hellbender conservation in the United States.
