Documenting an occurrence of a new wildlife species for a region is usually good news. Unfortunately, with the number of non-native species that seemingly pop up this is not always the case. Extension Specialists across the U.S. often receive inquiries about identifying pictures of wildlife. We were recently contacted by an individual to identify the “white frog” pictured below. It was clearly not a native species from Indiana but rather a Cuban treefrog.

The Cuban treefrog (Osteopilus septentrionalis) is native to Cuba, the Cayman Islands and the Bahamas. These treefrogs were accidentally brought to Florida in the 1920s, probably as hitchhikers in cargo containers on ships. Cuban treefrogs are considered invasive in Florida (and elsewhere outside their native range) because they are likely to harm our native ecosystems and cause a lot of problems for humans. They are voracious predators and have likely caused declines of native treefrogs in many suburban areas of peninsular Florida. They get into people’s homes and sometimes end up in toilets. And they are even known to invade electrical equipment and have caused power outages in Florida.

Cuban treefrogs are much larger than Indiana’s native treefrogs with adults typically reaching lengths of 2 to 3 inches and large females may grow to about 5 inches. Body color is highly variable, ranging from whitish to gray, green, or brown, and may be marked with irregular, dark stripes or blotches that fade when the frog changes color. Their skin is warty (some warts quite prominent) and have large “bug eyes.”. The armpits and groin may be washed with yellow.

Native gray treefrogs, which occur throughout Indiana, look a lot like Cuban treefrogs. However, gray treefrogs have granular skin and normally do not have individual warts that stand out from the rest of the bumpy skin on their back. Gray treefrogs also have a light-colored blotch directly below each eye.

How did the Cuban treefrog get to Indiana? That remains unclear, and this a very rare event for the Hoosier State. We only know of two other times Cuban treefrogs have shown up here.  Both were discovered in ornamental plants shipped to Indiana from Florida. Cuban treefrogs spread by hitchhiking on ornamental plants, motorized vehicles, boats, etc. and it is also possible that this frog was someone’s pet that was either intentionally or accidently released. Cuban treefrogs are adapted to warm environments and it gets too cold in Indiana for this invasive frog to live here.

What can you do to help?
It is import to document the locations of Cuban treefrogs outside of Florida in the US and Canada. If you see a Cuban treefrog, or suspect you have seen one, outside of peninsular Florida please email Dr. Steve A. Johnson at Include your name, date you saw the frog, where you saw it (state, county, city, street address), and also attach a digital image so Dr. Johnson can positively identify the frog. It is also important to report Cuban treefrog sightings at EDDMapS, the online mapping system for invasive species in the US. Visit and click the “Report Sightings” tab. Thank you for being a community scientist!

Propeller with muscles attachedWild Bulletin, Indiana Department of Natural Resources: As you prepare your boat or recreational equipment to get back on the water this spring, remember to look for aquatic hitchhikers. Zebra mussels, aquatic plants like Eurasian watermilfoil or starry stonewort, and many other invasive species continue to be a threat to Indiana’s waters by degrading fish habitat and negatively affecting recreational boating and fishing. The most common locations where plants, mussels, and animals hitch a ride include:

  • Transom well near the drain plug
  • Axle of the trailer
  • Lower unit and propeller on the boat motor
  • The rollers and bunks that guide the boat onto the trailer
  • Anchor and lines
  • Bait bucket and live well

Boat owners are asked to drain water from bait buckets, live wells, and boats before leaving the boat landing; leave drain plugs out while travelling on land; clean and dry anything that came in contact with water; and dispose of unwanted bait in the trash. Learn more about aquatic invasive species and how to prevent their movement.

Learn how to stop aquatic hitchhikers.

State of Indiana Proclamation-Invasive Species Week Feb. 27th to March 5th, 2022.Governor Eric Holcomb has proclaimed February 27th to March 5th as Invasive Species Awareness Week in Indiana.

This serves as an important reminder for Hoosiers to be aware and report potentially devastating invasives.

This proclamation states “invasive aquatic, riparian and terrestrial species influence the productivity, value and management of land and water resources in Indiana and the costs to prevent, monitor and control invasive species costs Indiana millions annually and after habitat destruction, invasive species are a great threat to biodiversity and threaten the survival of native plants and animals and interfere with ecosystem functions by changing processes like fire, nutrient flow and flooding”.

It continues with “invasive species impede industry, threaten agriculture, endanger human health and are becoming increasingly harder to control as a result of rapid global commercialization and human travel; and invasive species are as significant threat to almost half of the native species currently listed as federally endangered.”

As Invasive Species Awareness Week starts Sunday, February 27th, the Indiana Department of Natural Resources (IN DNR), Purdue Extension-Forestry and Natural Resources and the Indiana Invasive Species Council will answer any questions you may have.

Purdue Landscape Report sharing resources on spotted lanternfly.The interdisciplinary faculty and staff behind the Purdue Landscape Report, which provides science-based, timely information regarding Midwest landscapes to commercial growers, garden centers, landscapers, arborists and the general public, has been named as the recipient of the Purdue Agriculture TEAM Award, which was created in 1995 to recognize interdisciplinary team achievements of faculty and staff.
Teams must consist of three or more Purdue faculty and administrative/professional staff members. Team projects should include activities in one or more of the College mission areas of teaching, research and extension, and must have made demonstrable impact.

Led by Kyle Daniel, nursery and landscape outreach specialist in the Department of Horticulture and Landscape Architecture, the Purdue Landscape Report is a collaborative effort between Purdue Extension specialists and diagnosticians in the departments of Botany and Plant Pathology, Entomology, Forestry and Natural Resources, and Horticulture and Landscape Architecture. Articles cover everything from urban forestry and tree maintenance to pest and disease problems and management to plant selection and turf science. In addition to an email newsletter and online blog, PLR staff also provide live interactive webinars in order to highlight content and respond to questions from the audience.

“I believe this team embodies the spirit of this award – working together across department in the College,” said Dr. Linda Prokopy, Department Head in Horticulture and Landscape Architecture. “This team has indeed achieved more and is a consistent source of reliable, science-based information for homeowners and the green industry. The PLR team is doing a phenomenal job meeting the needs of an important industry in the state and they are very deserving of being recognized for this work.”
In the nomination for the TEAM Award, the impact of the Purdue Landscape Report team was described as:
“The quality of life and livelihood of many Hoosiers is greatly improved when cities and towns have healthy trees, shrubs, and flower beds. The task of growing and maintaining these plants is complicated by conflicting, incomplete or inaccurate media reports about the arrival of new pests and diseases; or how landscape choices, or use of certain management practices can have a negative impact on the environment and public health. Tree owners, landscapers and the professional workforce need timely science-based information to keep plants healthy in an environmentally sustainable manner.”
Since launching in February 2018, the Purdue Landscape Report has included more than 200 articles. PLR is sent out in a bi-weekly email newsletter to more than 4,000 subscribers nationwide. The online blog brought in 180,376 unique visitors in 2020.

In response to the pandemic, the Purdue Landscape Report staff also began a live, to addresses articles and hot topics. That series garnered more than 2,000 views.
In a January 2021 survey sent to PLR subscribers, 88% of respondents said they believed that the newsletter improved their ability to diagnose a problem, while 76% said that PLR has had a positive economic impact on their business.

A local professional shared that “Sometimes when I open up the PLR, it is like you have been reading my mind. The problem I have been seeing or thinking about is there in your headlines.”

Lindsey Purcell sharing tree planting tips at outside workshop. Purdue Landscape Report receives TEAM award.One PLR subscriber said “The Purdue Landscape Report is a great resource for myself and my team members. Within each issue is one or more topics that our team has encountered or discussed recently and the information provided by a very reputable source gives us the material needed to provide the best service to our clients and increase our knowledge base. The virtual sessions are another great resource provided that give an opportunity to have specific questions answered by experts.”

The impact extends from landowners to industry professionals and beyond.

“Often we take for granted the information produced in the PLR and we forget the countless dollars we have saved from information in the PLR,” said Rick Haggard, Indiana Nursery and Landscape Association Executive Director.

“The Purdue Landscape Report provides timely information to the Indiana Arborist Association members and associated parties in a format that is easily accessed and understood,” Associate Executive Director of IAA Ashley Mulis said. “The collaboration that goes into providing this product demonstrates the cohesive nature of several departments within Purdue University and the open sharing and comparison of information. The Purdue Landscape Report is an excellent addition to the many publications offered within Purdue Extension  in helping resource professionals manage the ever-changing landscape of pests, diseases and best management practices.”

In 2020, the PLR received the Extension Division Education Materials Award for Outstanding Blog presented by the American Society of Horticultural Science and received also earned the Team Award from the Purdue Cooperative Extension Specialists’ Association (PUCESA).

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 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 trees, grasslandsenjoy 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 beetlespotted 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

  • Are the leaves yellow, red or brown?
  • Are they spotted or discolored?
  • Do the leaves look distorted or disfigured?
  • Is there a sticky liquid on the leaves?
  • Do the leaves appear wet, or give off a foul odor?
  • Are leaves missing?
  • Are parts of the leaves chewed?

Check the trunk and branches

  • Are there holes or splits in the trunk or branches?
  • Is the bark peeling from a tree that shouldn’t shed its bark?
  • Are there tunnels or unusual patterns under the bark?
  • Is there sawdust on or under the tree?
  • Is there sap oozing down the tree?
  • Does the sap have a bad odor?
  • Do sticky drops fall on you when you stand under the tree? You might have spotted lanternfly. Please report it right away!

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!

Confused but think something is TERRIBLY WRONG?  Contact Purdue’s Exotic Forest Pest Educatorreport online, or call 1-866-NOEXOTIC.

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.
