The classic and trusted book “Fifty Common Trees of Indiana” by T.E. Shaw was published in 1956 as a user-friendly guide to local species.  Nearly 70 years later, the publication has been updated through a joint effort by the Purdue Department of Forestry and Natural Resources, Indiana 4-H, and the Indiana Department of Natural Resources, and reintroduced as “An Introduction to Trees of Indiana.”

The full publication is available for download for $7 in the Purdue Extension Education Store. The field guide helps identify common Indiana woodlot trees.

Each week, the Intro to Trees of Indiana web series will offer a sneak peek at one species from the book, paired with an ID That Tree video from Purdue Extension forester Lenny Farlee to help visualize each species as it stands in the woods. Threats to species health as well as also insight into the wood provided by the species, will be provided through additional resources as well as the Hardwoods of the Central Midwest exhibit of the Purdue Arboretum, if available.

This week, we meet the Virginia pine, or Pinus virginiana. In Indiana, this species is native to the southern part of the state, namely Clark and Floyd counties in the dry, hilly areas known as the Knobs near the Ohio River, but it has been widely planted across the state.

This native conifer has clusters of two needles, approximately two inches long, which are often twisted.

The Virginia pine has an open canopy. Bark on the Virginia pine is flaky, with a combination of gray and red-orange tones. The bark gets more orange higher up the trunk. Cones are one to three inches long and have very sharp thorns at the end of the scales. Cones typically stay on the tree for several years.

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

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.

This is the eighth in a series of consumer guides that describe fish and shellfish farmed in the Midwest region of the United States. The fact sheet also includes culinary characteristics, cooking tips and a recipe for Easy Baked Salmon.

Atlantic salmon, also known as sea-run salmon, kelts, and black salmon, are anadromous finfish in the Salmonidae family. Anadromous fish start their lives in freshwater and migrate to saltwater, returning to freshwater to spawn. Atlantic salmon are the only salmon species found in the Atlantic Ocean. They are native to the North Atlantic Ocean and coastal streams of North America and Europe and landlocked populations have been documented.1,2 They can be found in coastal waterways, freshwater streams, and lakes. They have long silver bodies with small black spots, appearing brownish from above. During spawning, males turn bronzish-purple with red spots and develop a hook-like lower jaw, known as a “kype.”

A rain garden is a green infrastructure project that can improve the quality of stormwater, minimize pollution, and enhance biodiversity and pollinator habitat. Purdue, Iowa State and Illinois-Indiana Sea Grant researchers explain how to site, size, design, install and maintain a rain garden, and provide advice on plant selection, too.

When stormwater runs off streets, driveways, roofs, and other impervious surfaces, it can move pollutants such as oil, fertilizers, heat, and chemicals to storm drains and eventually to natural bodies of water, such as lakes, streams, and rivers. These natural water sources are valuable resources for recreation, irrigation, and drinking water. Green infrastructure projects, such as rain gardens, can improve the quality of stormwater, reduce flooding, minimize pollution, enhance biodiversity and pollinator habitat, and create educational and recreational opportunities.

Green infrastructure includes a range of practices that allows stormwater to infiltrate into the soil or be stored for later use, thereby reducing flows to sewer systems and surface waters (U.S. EPA, 2022). A rain garden is one such practice. It is a small-scale landscape feature planted with native shrubs, perennial plants, or flowers in a shallow depression. It captures and stores runoff, allowing it to slowly infiltrate into the soil. At the property scale and when properly located, rain gardens lessen erosion in steeply sloped areas, reduce the potential for water to flow into basements, and minimize ponding in areas with poor drainage. The net effect of multiple green infrastructure practices can reduce streambank erosion and downstream flooding as stream flows decrease. Water quality is also affected as plants and microbes in the soil filter nutrients and some heavy metals as the stormwater soaks into the soil.
