The Indiana Tree Project has long been dedicated to expanding Indiana’s hardwood forests. They have partnered up with Natural Resources Foundation and the Division of Forestry to celebrate Arbor Day and Earth Day and help reforest Indiana. Limited edition tree shirts are now being sold. For each shirt purchased, two trees will be planted and you will be given an official tree certificate with a unique tree ID. This ID is used to pull the coordinates for the acre where the tree will be planted. The types of trees planted are native Indiana hardwoods and typically upland and bottomland oaks, walnut, black cherry, and other species that are in need of restoration. Please visit the Indiana Tree Project to learn more about how trees help wildlife, prevent soil erosion, and support our state’s largest agricultural industry.
If you are interested in participating in the next public tree planting, please email champton@dnr.IN.gov to receive updates.

Purdue University’s Tick INsiders program is looking for Indiana high school students and other Indiana residents willing to roll down their sleeves to get involved in a citizen science project.
Cate Hill, a Purdue professor of entomology, leads this effort to analyze the bacteria and viruses in Indiana’s ticks to build an understanding of what they are carrying and how that might impact human health. To do that, she needs volunteers to collect ticks from all over the state.
This year the Tick INsiders program will provide training for up to 50 students. Citizen scientists are also now welcome to collect and send ticks to Hill’s lab.
“It’s really important work. The Centers for Disease Control and Prevention reports that human cases of tick-borne diseases doubled from 2004 to 2016. If we’re going to get a handle on that and develop strategies for reducing tick bites and treating patients, we need to know where our ticks are and what our ticks are carrying around inside them,” Hill said. “That means we need a lot of ticks, and we need help collecting them.”
Three species of ticks – the blacklegged or deer tick, the lone star tick and the American dog tick – are found in Indiana. These ticks can transmit multiple pathogens, nine of which are known to cause human illnesses, though not all have been identified in Indiana. The Indiana State Department of Health reports more than 100 cases of Lyme disease each year and dozens of cases of Ehrlichiosis, anaplasmosis and Rocky Mountain spotted fever.
Research suggests that ticks can carry a cocktail of microbes – bacteria and viruses – that can sicken bite victims and may work in concert to affect the severity of an illness and human immune response.
“Not all tick bites are the same. We don’t know what is passed from a tick to a human each time someone is bitten, which means that health care professionals may need to consider multiple tick-borne pathogens in a person who has been bitten by a tick,” Hill said. “This program improves our knowledge so that we can improve our outcomes.”
Indiana residents interested in participating can collect ticks and send them to Hill’s lab for analysis. Videos on safe and proper collection techniques, as well as how to send ticks will be at Tick INsiders.

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.

This latest cold snap could kill some emerald ash borer populations in northern states like Minnesota. But in warmer states like Indiana, the invasive borer is one resilient bug.
“These guys are pretty good at burrowing in underneath the bark of the tree and that tree helps to insulate them from the bulk of the bad weather,” says Megan Abraham, director of the Indiana Department of Natural Resources Division of Entomology and Plant Pathology.
As a result, Abraham says it takes a long cold spell with really cold temperatures to kill off an emerald ash borer beetle. According to Purdue University, it would have to get down to about minus 28 degrees.
Kerry Bridges is an arborist with Tree Guy Incorporated in Bloomington. He says the emerald ash borer is not only used to Indiana winters, but it’s survived in much colder areas like Canada.
“I don’t foresee significant change or restriction of that bug’s reproduction and spread,” Bridges says.
What’s more, emerald ash borer and some other insects have a unique way of keeping warm.
Purdue entomologist Cliff Sadof says the reason your nose starts to run when it’s cold out is because your body is trying to keep it from freezing. Mixing mucus with water lowers the freezing point. Sadof says insects like the emerald ash borer do something similar.
“But they are changing the composition of the fluids inside their body, so they act like antifreezes,” he says.
According to the Indiana Department of Natural Resources, the emerald ash borer has devastated ash trees in every county in the state. Bridges encourages homeowners that are having problems with emerald ash borer to keep treating their trees…

Groundhogs are good at many things, said Brian MacGowan, Purdue University Extension wildlife specialist and Forestry and Natural Resources Extension coordinator, but predicting the weather definitely isn’t one of them.
The lore surrounding Groundhog Day originated in Germany where people used the reactions of badgers and hedgehogs to gauge weather patterns. When the tradition eventually migrated to America, Jarred Brooke, Extension wildlife specialist, said hedgehogs, which can be found throughout the United States, became the mammalian forecaster of choice.
“They’re crafty little critters,” McGowan explains, “which is why they’re found in so many different places. They’re habitat generalists and can live in open woodlands, grasslands, what have you.”
While MacGowan and Brooke agreed groundhogs don’t have a great track-record of weather prediction, other facts make groundhogs one of the more interesting members of the squirrel-family.

With winter upon us this is actually a good time to look for owls on your property. Most owls breed from January to March. You can either listen for calls in the evening, or use owl calls or recorded calls to get responses from owls in the area. We have three common species in Indiana and one rare species. All are non-migratory. However, each has different needs and habits. The following descriptions were written by Barny Dunning, professor of wildlife ecology at Purdue, and Jeff Riegel, field project supervisor at Purdue. These accounts were originally published in the Indiana Woodland Steward (www.inwoodlands.org).
Owls are among the most intriguing animals native to Indiana. They have been celebrated in story from the myths of the early Greeks to the books of Harry Potter. Owls are common across much of the state, but are relatively unknown, probably because of the nocturnal habits of these birds. But since they are efficient predators of mice and rats, among other things, owls are very useful birds to have around. Three species of owls are common year-round residents in Hoosier forests. The largest of these is the great horned owl, one of the dominant predators of our forests. Most people are surprised to learn that the great horned owl is as common as the familiar redtailed hawk even though the owl is much less likely to be seen.
Great horned owls hunt in open areas but nest in large trees, where they take over a nest abandoned by a hawk, crow or heron. They are common where both woods and fields mix. The owls start breeding in January and February, adding new sticks to an old nest and laying a clutch of three eggs. Most species of owls nest very early in the year so that there will be a lot of easily caught prey in the form of young mammals and birds when the owl chicks are learning to hunt on their own. Many nests of the great horned owl are in snags or trees with broken tops, therefore retaining some of these forest features will provide good nesting spots for this dominant bird.
A second species of large owl is found in the larger woodlands of Indiana. The barred owl is most common in the interiors of forests and spends less time along the woodland edge. One major reason for this is the presence of the great horned owls, which will kill and eat a barred owl. Barred owls usually nest in the cavities of deciduous trees, laying their eggs in deep winter. Their dependence on tree cavities means that barred owls are likely to respond well to land management activities that retain large trees on a property and increase the number of snags with cavities. They also do well when there are forest patches of a variety of ages on a property, in addition to the older trees that provide nest sites.
Eastern screech-owls are the smallest resident owl in the state. They nest in small tree cavities and readily make use of nest boxes made especially for them. More than the other two species, screech-owls are found in suburban backyards, urban parks and on college campuses – anywhere there is a variety of trees and shrubs. Screech-owls feed on small prey such as insects, songbirds and mice. They breed later than do the big owls, and have active nests in March and April. In addition to nest boxes, these owls willuse old cavities excavated by northern flickers, tree holes created by storm damage, and hollow trunksof snags. Their ready use of a wide variety of cavity types makes our screech-owls a prime beneficiaryof snag retention and other habitat improvement activities. Indiana’s smallest owl does not breed here, but its numbers during the fall migration can be in the thousands statewide. The northern saw-whet owlbreeds from the most northern states on into Canada and migrates from there when food becomes scarce. “Swets” are an irruptive species, meaning their populations rise and fall dramatically from one year to the next on a roughly four-year cycle. A group of volunteer researchers in Yellowwood State Forest began studying the movements of these owls in 2002 as part of the larger Project Owlnet (www.projectowlnet.org). Their first year produced 71 owls on just one ridge in Yellowwood. Since then, the annual numbers have averaged around 70, but nearly 200 owls were captured and banded on that same ridge in 2007. The low point in the cycle was in 2009 when only nine owls were captured. There are now eight such banding stations scattered around Indiana. Brookeville Reservoir had the largest number of captures in 2009 with 32; while an Indianapolis station tallied only six. Some northern saw-whet owls winter in Indiana where forests with an open understory provide good foraging opportunities throughout the winter months.
The rarest owl in Indiana is, paradoxically, the species with the largest geographic range. Barn owls are found across the globe, but in the Midwestern United States their populations have declined dramatically. The species is considered endangered in Indiana. Barn owls originally nested in tree cavities, but when early settlers built barns and other farm buildings, the owls were quick to adapt. They are not limited to barns however, as recent Hoosier nests have been found in old churches, silos, and within the walls of abandoned buildings. To be suitable, human structures must have openings that allow the owls to fly in and out and an interior area that is undisturbed and big enough for the nest. The biggest factor in their decline has been changing agricultural practices. Barn owls hunt in open areas such as pastures, but do not use rowcrop fields. As Hoosier farmers converted pastures to corn and soybean, the barn owl lost its hunting grounds. Farmers in the southern part of the state that still retain some open grassy fields on their land can contact the state Department of Natural Resources to have a barn owl nest box added to their outbuildings if they don’t have appropriate nest sites.

It all starts with providing some supplemental nutrition for small to medium-aged trees in the late fall when trees go into a state of dormancy. This is when trees stop active growth and begin to form terminal buds, drop leaves and develop cold resistance. Adding fertilizer to trees too early in the season can push new growth which will be prone to winter damage.
A fertilization program is used to maintain trees in a vigorous condition and to improve their immune system against pests. Fertilizing trees refers to the practice of adding supplemental nutrients (chemical elements) required for normal growth and development. However, you really can’t “feed” a tree, since trees are autotrophs. They use nutrients to feed themselves by making sugar in the leaves through photosynthesis.
Nitrogen (N), phosphorus (P), and potassium (K) are plant nutrients needed in the largest quantity and these are most commonly applied as a complete fertilizer. However, the addition of any soil nutrient is recommended only if soil or plant foliage tests indicate a deficiency. For trees and shrubs in most of Indiana, the two most common causes of nutrient problems are high pH (alkaline) soils, which can lead to chronic deficiencies of nutrients in some tree species, such as red maple and pin oak, and nitrogen-deficient soils. Typical symptoms include yellowing chlorotic leaves and reduced growth and smaller leaf size.
Trees in natural settings get nutrients from the air, organic matter, nutrient cycling, and microbial activity. In many cases, supplemental nutrition is not necessary in fertile soils which have enough nutrients in the proper amounts to support healthy growth, especially on established trees, but in the urban and suburban environment, often a little assistance is needed. The more challenging urban environment provides less opportunity for healthy growth due to poor, fragmented soils, reduced microbial activity and compaction. Trees needing fertilization to stimulate growth include those exhibiting the symptoms of pale green, undersized leaves, chlorosis, reduced growth rates and those in decline resulting from insect attacks or disease problems. Also, turf can be a serious contender for nutrients and trees surround by turf benefit from additional nitrogen applications every couple of years.
Trees which should not be fertilized include newly planted trees in the current year and those with root damage from recent trenching, construction or other disturbance. The root systems of these plants will need to re-establish before fertilizers are applied with cultural practices such as supplemental moisture and mulch. Older, established trees do not need to be fertilized every year and may never need supplemental feeding. In fact, serious pest problems can result on over-fertilized trees. Research indicates that young deciduous trees benefit from additional nitrogen in low-analysis, slow release forms. Conifers require less fertilization and are genetically adapted to low-nutrient soils.
