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.

MyDNR, Indiana’s Outdoor Newsletter: Do you have bats roosting on your property? Help DNR by counting how many bats fly out during a few evenings this summer. Monitoring bats as they emerge from roosts helps us manage the reproductive health of bats across the state.

The Summer Bat Roost Monitoring Project uses volunteers to collect information on the distribution, occupancy and abundance of bat colonies throughout Indiana.

Participants must have bats roosting on their property or permission to enter property where a roost occurs. Possible roost sites include trees, bat houses, barns, attics, outbuildings and other structures. On each night of surveying, volunteers count the bats that exit the roost and record weather information. Each survey takes about an hour and is conducted on eight to 12 nights from mid-May to mid-July.

Newsletter can be found online May: DNR: Communications: MyDNR Email Newsletter (in.gov)

For more information please visit Summer Bat Roost Monitoring Project.

To sign up for the project, visit the Division of Fish & Wildlife’s volunteer page and select “Find an ongoing service project.” Wildlife Diversity staff also monitor bats using mobile acoustic surveys and acoustic monitoring stations.

Purdue Landscape Report: It’s that wonderful time of year again where temps are rising, life is coming back into the landscape, and people are thinking about how to improve the urban canopy around them.  Well, maybe not that specifically, but we have the urge to plant trees.  Whether it’s for Earth Day or Arbor Day or you just enjoy the act of planting, one of the hot topics is getting trees into the ground.  That’s not what I’m here to talk about today, though.

As much as I love assisting communities with their greening efforts, getting the right tree in the right place, planting is not the only way to help grow the canopy around you.  One of the topics that can be neglected is maintaining trees from previous plantings.  Often, trees get placed in the ground, they are mulched, watered, and staked, then left on their own to make it in the world.  New trees can take about 2-5 years to become established in their new homes and they could require assistance from us for much longer to thrive.  Luckily, there is a simple activity to do assist trees, young and old.

Just like when they were placed in the ground, trees still benefit from mulch.  Reapplying mulch benefits trees in multiple ways.  It’s a natural way to prevent weeds and grass competing in the root zone and adds a protective buffer against mechanical damage from mowers and weed eaters.  It will also help to maintain moisture levels in the soil as we transition into the hotter summer months.  When applying new mulch, don’t worry about removing the old layer.  It’s working its way into the soil around the tree adding organic matter, improving the quality of the soil.

Add enough mulch so there is a 2–3-inch layer sloping away from the tree with at least a 3–5-foot radius around the stem (older, larger trees can benefit from larger mulch rings).  No volcano mulching (Figure 1), make sure you also have around a 1-2-inch gap between the stem and the start of the mulch ring (Figure 2) to prevent unwanted root growth above ground and rot from excess moisture on the stem.   Continuing this practice every year can help maintain soil moisture levels, while enriching the soil around your tree, maintaining a safety zone, and adding a nice aesthetic.

Purdue Landscape Report: Pseudomonas syringae pv. syringae is an opportunistic bacterial pathogen that attacks a diversity of woody ornamental plants. The bacteria cause flower blights, cankers, shoot blights, and diebacks.

Symptoms
Symptoms often begin as expanding leaf spots. On lilac and viburnum, small spots expand to irregularly shaped brown lesions with yellow halos (Fig. 1). For most other hosts (cherry, pear, basswood, dogwood, hydrangea, high bush-cranberry, mountain-ash), infected leaves turn reddish brown or black and usually remain on the branch after they die (Fig. 2). As the bacteria spread into woody tissue, dark, sunken sections of the stem (cankers) expand, working their way back toward the trunk from infected leaves and flowers. Leaves attached to a cankered branch will wilt while the tip of the affected branch curls and droops like a shepherd’s crook (Fig. 3). Cloudy droplets of sticky fluid (ooze) may accumulate on leaf tips, leaf surfaces, stems, and even infected fruit.

Image of infected flowers result in blossom blast.
Figure 2. Infected flowers result in blossom blast. The continued growth of the bacteria can result in cankering and blight. Photo by George Sundin.

Life Cycle
The bacteria overwinter and persist in cankers, along with asymptomatic bud and twig tissue. In presence of water and warming temperatures, bacteria multiply and may ooze from infected tissue. Wind-driven rain, insect, or mechanical pruning spread Pseudomonas. Bacteria enter the plant through flowers or injury.

Management
All bacterial pathogens, including Pseudomonas, invade flowers or wounded tissue. To prevent or minimize the risk of infection:

• Use disease-free plants and budwood.
• Prune in the late winter/early spring.
• When pruning, do not mix pruning to shape woody ornamentals with pruning to manage disease.
• When pruning to remove infected shoots, be sure to disinfect shears between plants.
• Minimize overhead irrigation when possible to minimize splashing and pathogen spread.
• Avoid over-fertilization practices that drive excess succulent growth.
  

  Figure 3. Bacterial blight is a common scourge to common lilac. Using resistant varieties is the best way to protect against the disease. Photo by Janna Beckerman.

• Avoid late season fertilization practices that prevent plants from achieving timely dormancy and promote freeze damage and/or winter injury (Fig. 4).
• Choose zone appropriate plants to avoid freeze damage and/or winter injury.
• Choose disease resistant plants, when available. The following lilac varieties were found to be resistant over a four-year trial: Donald Wyman, Royalty, Superba, Miss Kim, Edmund Boisier, Victor Lemoine, Dwarf Korean, Mme. Antoine Buchner Isabella, Sensation, Anna Amhof, Krasavitska Moskvy, Michael Buchner, and Alphonse Lavallée.

Foliar sprays of some copper-based bactericides (e.g., Camelot, Kocide, and Nu-Cop) were found to reduce disease incidence in trials on lilac (Vey and Palmer, 2018). Avoid using copper under cool, humid conditions to reduce the risk of phytotoxicity and damaging plants. Copper resistant populations of Pseudomonas syringae have been reported in other crops (vegetables, stone fruit). Products containing acibenzolar have provided inconsistent control in multiple trials but is labeled for use. Use of quaternary-ammonium disinfestants (KleenGrow) have been found to reduce bacterial populations and disease incidence and should be considered as part of any rotation with copper products. Due to the diversity of copper products, be sure to test for phytotoxicity issues prior to large scale treatment of crops.

This exotic invasive tree species is commonly found in Indiana landscape, callery pear. Callery pear has been planted as an ornamental tree in the midwest for decades. The original selection bradford pear was actually infertile and would not spread from seed but additional varieties have been planted and have crossed with the original Bradford and those are producing fertile seed. Find out how the seed spreads and what we can do to help our forest.

Purdue Landscape Report: Asian jumping worms, a group of invasive earthworms, have gained a significant amount of media attention in the last several weeks, and for good reason.  Unlike the nightcrawlers and other earthworms we know, Asian jumping worms do not improve soil health to the benefit of plants.  Instead, jumping worms (also called crazy worms, snake worms, or ‘Alabama jumpers’) almost completely strip nutrients out of soil, altering the soil structure and severely impairing the ability to develop many kinds of plants. After they are done with an area, Asian jumping worms leave behind soil that has a texture similar to that of coffee grounds and very low nutritional value. On top of this, Asian jumping worms are capable of reproducing asexually, allowing their population to grow very rapidly and making them an invasive species of some concern.

Identification
The good news is that Asian jumping worms are not well-suited to Indiana’s environment.  They aren’t capable of surviving winters in any life stage except as an egg, meaning their activity periods are limited to late June to the first hard frost of the year.  If you see worms outside of this period, it’s highly unlikely an Asian jumping worm.  There are also a few traits the worms have that you can use to visually confirm their identity.  First off, Asian jumping worms are accurately named; when handled, they writhe and thrash similar to snakes, setting them apart from common earthworms and nightcrawlers.  Jumping worms also tend to have drier skin that has an almost iridescent appearance, as compared to the slimy, moist texture of the beneficial earthworms we need for good soil health.  The most consistent feature is an organ known as the clitellum, or the reproductive organs of worms.  On common earthworms, this looks like a saddle-shape that partially covers several segments, is normally reddish-brown, and is raised off the surface of the body.  On an Asian jumping worm, however, the clitellum is indistinguishable from other segments, save for their pale, milky color.
