Trees are lost every year from storm-related events. Major damage to parts of the tree or even the entire tree can result from high winds, snow and ice. Historic, specimen and significant trees provide value to the landscape and the community, and these trees can become aesthetic, financial and social losses in storms. In addition to physical damage or loss, risk and liability can become a concern to people and the surrounding property. Seasonal storms can cause extensive damage depending on timing and intensity. Deciding what to do with damaged trees is an important process.
Over time, trees swaying in the wind develop extra strength to withstand directional forces. If conditions are consistent, trees will initiate changes in their development to compensate for these loading patterns. They are biologically engineered to adjust to external loading, under normal conditions. This fiber strength can minimize the impact of external forces, unless they are excessive, such as during a storm. Typically, these loads come from wind. However, ice and snow also can cause damage from excessive weight on branches.
Typical weather events are not an issue for trees. They are engineered to withstand normal conditions. However, some storms can exert extreme forces, resulting in injuries of varying degrees. It is at this point that a tree owner or manager must make an informed decision based on the extent of the damage. The assistance of a trained arborist can help determine if a tree can be saved from sustained injuries, or if it requires removal
The response to storm damage should be based primarily on two concepts: risk and sustainability. If the tree is an imminent or likely danger to people, property or activities, the decision leaves little room for options. However, if the residual risk from the damage is determined to be of an acceptable level and the injury to the tree not life- threatening, mitigation may be possible to save the tree and reduce the danger.
There are several types of tree damage that occur from violent weather. Each has its own specific assessment considerations. All parts of the tree should be inspected during a post-storm assessment.
Some common damage found includes:
Wind Throw
The entire tree is “pushed over” by high winds. The loading forces on the aerial tree portions are too great for the developed root system. Previous harm from activities such as construction damage, lack of maintenance and attacks from pests predisposes the tree to damage with poor anchorage or health. Inspect the root plate of each tree on a regular basis to determine if there are any root health issues. Look for fungal fruiting bodies, exposed roots, lifting or other damage. Larger or more mature trees that have been completely uprooted are typically not salvageable
Stem Failure
Trees will fail at their weakest point. Typically, failure is caused by the combination of a defect and external forces. Old injury sites or wounds are common on tree trunks, and these damaged areas can lead to tree failure under excessive loads. Also, trees newly exposed to prevailing winds from development or removal can be at greater risk. Trunks can snap or buckle if the tree is unable to withstand the wind forces. Damage from stem failure usually cannot be repaired. Trees with major defects on the trunk should be examined carefully to determine the degree of risk for that location. Look for decayed areas, cavities, nesting holes and fungal fruiting bodies for indicators. The extent and location of these defects will help the arborist determine the potential for failure.
Crown Twist
The tree canopy contains an array of leaves, twigs and branches that make up the crown portion of the tree.
Many times, the crown can have an uneven geometry from competition or poor pruning, leaving an unequal appearance. The result of this situation in high winds can be trouble. Uneven wind loading on the lopsided crown produces a damaging twist on major branches and the stem. This twisting causes torsional stress, much like twisting a rope backwards, resulting in splits and cracking. This is especially damaging around old wounds or other defects, which can lead to failure. Close investigation is necessary to spot these often-subtle cracks. Often this damage can be mitigated in branches; however, take caution with damaged trunks.
Root Failure
Stability and anchorage are important roles of the root system for keeping a tree upright.
Both the structural, woody roots and the fine absorbing roots create an effective network of strength to withstand wind-loading forces. As the tree becomes larger, increased stress is put on the roots to maintain stability.
Roots that are restricted, diseased or damaged can cause trees to lean and fall. Careful examination of the root plate is needed to determine if anchorage is compromised. Look for heaving soil and roots around the tree trunk, which can present a high-risk situation. The presence of pulled or broken roots, as well as any mushroom development around the root system, also can be indicators of defects in the roots. Depending on the age, size and degree of exposure, mitigation may be possible. Young trees with healthy roots systems can be up righted and staked or guyed with success. However, if more than 30 percent of the roots are exposed, removal may be the better option.
Branch Failure
Tree branches are easy victims of loading forces. Whether it is axial loading from snow or ice accretion or lateral, side loading from wind, damage is frequent. Because branches can sometimes be poorly attached to the main stems, they can easily experience injury. However, this structural arrangement allows the branches to be flexible and disposable, and easily shed in times of stress to help dampen the impact of wind, minimizing damage to the larger, structural branches.
Poor architecture and development, such as codominant stems and included bark in branch junctions, predisposes branches to failure and often are the first to experience damage. Branch failure can be easily repaired and not lethal to the tree unless more than half the crown has been destroyed. However, they can create high-risk situations in the wrong places. Learn to recognize dead, broken, hanging limbs or other signs of damage to reduce risk. Often twisted and cracked branches are difficult to see and may need closer inspection by an arborist to identify. Be sure to use pruning best practices when correcting damage in the crown.
There are other forms of damage, such as lightning damage, which can be detrimental and even lethal to trees. A certified arborist or qualified consulting arborist can help provide a prognosis.
Storm Damage Prevention
It is impossible to protect a tree from storms or prevent damage from weather events. However, there are some actions that can minimize injury to trees.
The best preparation begins when trees are young or newly planted. Do not stake or guy trees unless absolutely necessary. This prevents development of internal adjustments to wind with response wood growth. Let the tree adjust to local conditions by allowing natural movement.
Functional pruning helps trees form a healthy, more wind-resistant crown. Inspection and corrective pruning of newly planted trees produces a stronger structure. Eliminate codominant stems by pruning these weak- forked branches. Choose a good, strong central leader for young trees. This will prevent losing the whole crown in the future. Choose branches with even spacing, radially around the tree for balance and symmetry.
Inspect trees for broken, dying, diseased and dead branches each year. Also, conduct a visual assessment after a storm event. Look for crossing branches, which lead to problems where rubbing produces damage and decay. Always favor branches with a “U” shape or greater than 45° angle, which forms an optimal connection. These branches will have fewer tendencies to split or break from wind or ice loads. Eliminate branches with bark inclusion and tight or narrow branch junctions.
Branch training is essential for sustainable, long-term tree plantings.
Under no circumstances should a tree be “topped” to prevent wind or ice damage. Topped trees produce many small, poorly attached sprouts and as they grow, the canopy weight and density is actually increased. In addition, topped branches often develop decay and diseased stems, which further weakens the tree and makes the branches more susceptible to breakage. Topping may seem to make a tree safer, but it actually increases the potential for storm damage with unhealthy epicormic sprouting and additional decay in the stems.
When mature trees develop unequal crowns, prune to improve symmetry. However, remember pruning best practices and never remove more than 30 percent of the crown at one time. It may take several years for crown restoration. Good pruning techniques also promote faster healing of the cuts.
Do not try to “wind-proof” the tree by thinning out branches. Trees rely on proper branching habits and placement to dampen the wind energy affecting them. Excessive and unnecessary pruning creates wounds and additional stress on tree health. Allow the tree to develop fully and naturally by pruning only when needed. However, proper health care includes pruning for vigor. This includes removing dead, dying or diseased branches, poor branch attachments, crossing branches and narrow branch angles. After this functional pruning, some thinning is achieved to reduce drag or sail in the canopy.
A healthy tree is the best defense to any challenge the tree may face in its lifetime. Appropriate watering and fertilization improves root growth and structure, making the tree more stable. Monitor for pest problems and treat when needed to prevent insects and diseases from weakening tree health. Remove diseased branches, as needed, to minimize spread and potential damage.
Risk Assessment
Following a severe storm event, not all trees will need to be pruned or removed, and many will need little or no treatment. After identifying the type of damage, risk assessment is the priority. One of the more critical tasks for the property owner is determining an acceptable level of risk. It is the responsibility of a tree owner or manager to maintain and manage their trees to protect the safety of others. This usually requires assistance from a well-qualified arborist.
Post-Storm Response
Damage assessment is the next step. Review the affected tree or trees to determine the level of injury. Some trees may not require any action and can recover on their own. The challenging part of the assessment is deciding which trees can be pruned properly to a healthy state and which trees should be removed. Many factors are involved in the decision, and damage may be hidden or difficult to determine. It is critical to get a professional arborist with credentials to conduct the assessment and the work required to mitigate the injured parts of the tree.
Hire a Certified Arborist
One key to dealing with the challenges of storm damage is to consult a qualified tree service. Finding a qualified tree care professional is important protection for the property owner. Sometimes less credible companies follow storms to take advantage of a bad situation. Knowing how to hire a reputable arborist can protect a property owner from being victimized. A professionally trained arborist can determine if a tree can be saved. Even if the tree must be removed, safety and training are needed to prevent additional damage or injury from the removal. An International Society of Arboriculture Certified Arborist can help save a tree or improve the risk situations that follow storms. Also, choosing an accredited company brings the highest level of standards for client satisfaction and safety.

In the past few years, prescribed fire has caught on in Indiana. Government agencies and land trusts have increasingly used it as a tool to create wildlife habitat, manage for rare and endangered species, and promote ecosystem health. On these properties, fire has been reintroduced to landscapes it shaped for thousands of years.
However, while fire is being used to improve our public lands, 96% of Indiana is privately owned. If fire is
truly going to spread, private landowners need to start burning as well. One means to that end is the formation of Prescribed Burn Associations.
Prescribed Burn Associations (PBAs for short) are, at their most basic level, groups of people who burn together. By burning as a group, members of the PBA can share expertise, equipment, and labor to get more fire on the landscape. They can also pursue training and funding opportunities that may not be readily available to individuals. In Missouri, the formation of 18 PBAs has led to prescribed fire on more than 11,000 acres across the state in the past 10 years. The model for success is already out there.
Indiana is just getting into the PBA game. One PBA based in Daviess County already exists, and interest meetings for two more in Brown and Harrison are on the calendar for fall of 2026. More meetings are in the works across other parts of Indiana.
So, how does one get involved with a PBA? If you happen to be in one of the counties mentioned above, it’s as simple as contacting the leader or attending a meeting. Fire experience is not a requirement, only enthusiasm and a willingness to learn. Members don’t have to be landowners either – many PBAs include professionals, students, and folks who are simply interested in learning new land management skills.
If there isn’t a PBA in your area, consider getting one started. Find a few other people who want to be involved, hold an interest meeting to share information and sign folks up, then elect a board. From there, the board guides the organization and helps create its rules, and the larger membership decides on a coverage area and name. Then, all that’s left to do is inventory available equipment and expertise, line up some burns, and start getting good fire on the ground.
Still not sure how to start? That’s where we can help. If you are interested in starting or joining a PBA, you can fill out this PBA Interest Form, and we will reach out to help you get started.
With the formation of PBAs across the state, fire can be more broadly used as a management tool, benefiting the natural world and humans alike. For more information on PBAs, including formation tips and upcoming meetings, visit the Prescribed Burn Associations website.

Description of Bovine Tuberculosis:
Bovine tuberculosis (bovine Tb) is a disease found in mammals caused by the bacteria Mycobacterium bovis (M. bovis). In North America, bovine Tb is most commonly found in domestic cattle and captive and wild cervids (white-tailed deer, elk, etc.) and less commonly in other mammals such as raccoon, opossums, coyotes, and wild boars.
Bovine Tb has been greatly reduced in the cattle industry since the National Cooperative State-Federal Bovine Tuberculosis eradication program began in 1917. Currently, most states are accredited as “Bovine Tuberculosis-Free” by the United States Department of Agriculture, however, sporadic outbreaks do still occur throughout the United States.
Cattle, captive cervids, and wild white-tailed deer are considered reservoir hosts for bovine Tb. A reservoir host is a species in which bovine Tb can persist and be transmitted among individuals within a species or be transmitted to another species. Wild white-tailed deer may pose the greatest threat to the establishment of bovine Tb on the landscape because they move freely across the landscape and may contact multiple domestic cattle herds.
In Indiana, bovine Tb was detected in domestic cattle in 2008, 2010, and 2011 and most recently in April 2016 and a captive red deer and elk herd in Franklin County in 2009. The first case of bovine Tb in a wild white-tailed deer in Indiana occurred in August 2016 in Franklin County. All confirmed cases of bovine Tb in Indiana have been from the same strain of M. Bovis.
As of Dec 14th, 2016, 2,024 white-tailed deer samples have been collected, 2 exhibited lesions consistent with bovine Tb; 1,897 samples have been tested and 0 samples have tested positive for bovine Tb.

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. A new DNR tool allows individuals with bats roosting on their property (or a property where they have access) to report the roost to DNR mammalogists.
This data allows biologists to learn how and where bats and humans coexist. Over time, the data will contribute to a map of these locations. The information will also guide outreach efforts and allow DNR biologists to contact property owners who submit reports for additional survey opportunities.
Data collection projects and many of the outreach and conservation efforts that result from them are made possible largely thanks to donations to the Nongame Wildlife Fund.
