Purdue Landscape Report: Most people these days have, at the very least, heard of Callery and Bradford pear trees and know something about the invasiveness of this ornamental street tree.  But I still get questions about what it is and why it’s so bad. So, I’d like to offer a little history of this infamous tree.  Where did it come from, why is it so popular, why is it such an awful tree to plant, and some suggestions for better species to plant in its place.

Pyrus calleryana, the Callery pear (Fig. 1), was originally introduced from Asia to the United States in 1908.  This was done in an attempt to breed pear trees that were resistant to fire blight, a bacterial disease that can spread rapidly causing leaves and branches to blacken as if burnt by fire, eventually resulting in death.  Along with its resistance, the Callery pear was tested as a rootstock for the edible European pear (Pyrus communis) and its vigor in growth.

Callery Pear grows to a height of 30 to 50 feet with a spread up to 30 feet wide.  Thick leaves grow alternately, are dark green, grow with sharp spurs along branches, and turn reddish-purple in the fall.  They are one of the first trees to bloom and begin to grow in the spring and one of the last to drop their leaves in the fall.  They produce a beautiful show of white flowers in the spring that have an unfortunate odor and an abundance of small fruits in the fall that are spread by birds and other wildlife.  In fact, invasive European Starlings are one of the primary species that feed on and spread the fruits and seeds.  Stems are smooth with light-colored lenticels while more mature stems are light to medium grey with fissures along the bark. Branching is usually upright in structure leading to poor branch unions that are weak and prone to failure.  They grow quickly and tolerate a wide variety of planting locations and conditions, which led to the widespread use as both street and ornamental trees in urban plantings.

The Bradford pear tree is a variety of Callery pear cultivated in the early 1950s as a sterile tree without sharp spurs.  Unfortunately, it cross-pollinated with other varieties leading to the rapid spread and out-competing of native species that we see in fields, along roadsides, and in forests today (Figs. 2 & 3).  As awareness of the environmental issues of Callery pear spreads, local and state governments are working on removing them from the landscape.  It is often joked that pruning these trees is extremely simple, involving a single cut at the base of the tree.

Due to the extensive use of these trees over the past 7 decades though, removals can lead to a large loss of existing canopy, especially with mature trees.  This loss is worth negating the ecological damage they cause and with patience can be replaced with more appropriate species.  Suggestions include serviceberry (Amelanchier laevis), flowering dogwood (Cornus florida), redbud (Cercis canadensis), and crabapple (Malus sylvestris).

For more information on invasive pear trees or on how to remove them see the links below.

With storm season just around the corner, one topic of concern on many minds is damage to and from trees. Depending on the intensity of the storms and the condition of the trees, damage from high winds, heavy rainfall, and lightning can be quite severe. Cracked or broken branches, stem failure, and root failure are some of the main concerns, but also the risk and liability of damage to people and property.

If your tree is damaged, there are some steps to deal with the situation. First and foremost, consider the safety of yourself and others around you. Inspect the tree from a distance first looking for the following:

• Heaving of the ground indicating potential root failure
• Damage to limbs and/or the trunk of the tree
• Hanging branches can fall to the ground resulting in injury or death
• Be aware of utility and power lines. Trees can become charged by coming in contact with live wires. All utility lines should be considered energized and dangerous.

If you find your trees damaged from a storm hiring an International Society of Arboriculture (ISA) Certified Arborist to perform a risk assessment will help guide your decision of how to manage your tree. To find an arborist near you and verify credentials use the link at Find an Arborist, Trees are Good, International Society of Arboriculture (ISA). For more information, you can also view the publication, Trees and Storms, located in The Education Store, Purdue Extension’s resource center.

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) 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.

MacGowan’s impressive portfolio spans a wide variety of topics from human-wildlife conflict, wildlife damage management, reptile response to forest management, youth natural resources education, and evaluating the impact of extension scholarship. He has been honored for his extension programs and deliverables throughout his career. He won the Agricultural Communications in Education Gold Award twice: for electronic publications “Snakes of the Midwest” in 2005 and for website “Everything Wildlife” in 2003. He also received the Association of Natural Resources Extension Professionals (ANREP) Gold Award for mixed materials “Wildlife CSI Unraveling the Mysteries of Wildlife Crop Damage” in 2007. He also earned the ANREP Silver Award for video/DVD/CD and for web-based courses for “Wildlife CSI Unraveling the Mysteries of Wildlife Crop Damage” in 2007.

MacGowan has been a member of the Indiana Woodland Steward Editorial Board since 2007, is the editor of the Indiana Woodland Steward newsletter and has served as the project investigator for the Renewable Resources Extension Act (RREA) in Indiana. He also organizes the yearly Ohio Valley Woodlands and Wildlife Workshop, conducts professional development workshops for the Natural Resources Conservation Service (NRCS) and other conservation partners and shares his knowledge at many extension events throughout the state.

MacGowan was instrumental in producing the Woodland Stewardship for Landowners video series. He also shared his knowledge on several editions of FNR Ask An Expert and provided instructional assistance regarding protecting plants and shrubs from wildlife, how to stop woodland animals from digging in your flowerpots, deer fencing, hummingbirds and more.

“I’m overwhelmed, especially knowing who has received this honor before me,” MacGowan said. “It’s one of the highlights of my professional career.  Working at Purdue, and really in the wildlife profession, has put me in the position to work with some outstanding individuals. You hope that you have made a difference in people’s lives during your career. I got into the wildlife profession because I loved the outdoors. But, it’s the people you work with every day that makes it special. I’m extremely appreciative and humbled by this honor.”

Previous Purdue Forestry and Natural Resources affiliated winners of the Hoosier Wildlife Award include current or emeritus faculty members Dr. Rob Swihart (2016), Dr. Harmon “Mickey” Weeks (2006) and Dr. Russell E. Mumford (1996).

MyDNR, Indiana’s Outdoor Newsletter: Indiana DNR has confirmed the state’s first positive case of chronic wasting disease (CWD) in LaGrange County. CWD is a fatal infectious disease, caused by a misfolded prion, that affects the nervous system in white-tailed deer. It can spread from deer-to-deer contact, bodily fluids, or through contaminated environments.

There have been no reported cases of CWD infection in people, but the Centers for Disease Control and Prevention (CDC) recommends that hunters strongly consider having deer tested before eating the meat. The CDC also recommends not eating meat from an animal that tests positive for CWD.

CWD has been detected in 33 states including the four bordering Indiana (Ohio, Michigan, Illinois, and Kentucky). Because CWD had been detected in Michigan near the Indiana border, a detection in LaGrange County was likely.

If you see any sick or dead wildlife, deer or otherwise, please report your observations on the DNR: Sick or Dead Wildlife Reporting page.

For more information visit DNR: Chronic Wasting Disease (CWD).

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

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.
