MyDNR: Annually, more than 14,000 deer-vehicle collisions are reported in Indiana. If you live where deer are found, especially in suburban areas or where field and forest meet, it is important to know ways to reduce the likelihood of a collision and what to do if you are involved in one. While you can’t eliminate the possibility of running into a deer on the road, you can minimize the risk of severe damage to you or your vehicle.

Deer movements are not random, and the likelihood of seeing deer near roads varies by time of day and month. Deer are most active when many people are commuting to and from work, resulting in increased collisions. While your chance of hitting a deer varies, in general, deer-vehicle collisions are most likely to occur during these conditions:

• At dawn and dusk when deer are most active.
• From September through December, particularly October and November during deer mating season as bucks cross roads more frequently and are less cautious when crossing.

As trees grow and reach heights which many consider to be unsafe, tree owners would often top their trees by reducing the tree size. This is by heading back most of the large, live branches from the tree. However, topping trees proves to be more damaging than beneficial.

Topping trees can cause decay, weak branch attachments, and an increased likelihood of failure. If we do not top our trees and leave them to develop naturally, the structural strength of the trees is stronger than those that are not topped. The extensive root system, when left undisturbed, provides adequate support for the trees.

This publication titled What’s Wrong with Topping goes in-depth on the implications of topping and provides better alternatives to topping.

Purdue Forestry and Natural Resources News & Stories: Vultures have a role to play as nature’s garbagemen, cleaning up animal carcasses, but what happens when a species goes from scavenging to harassing and even preying on livestock?

Pat Zollner, professor of wildlife science, along with PhD student Marian Wahl and their partners with the USDA Wildlife Services program are investigating black vultures in Indiana in order to better understand vulture ecology as well as to develop methods to mitigate future harm to Indiana livestock.

“Black vultures are relatively new to Indiana, they have been gradually moving in from the south, and right now there are a lot of unknowns that we need to figure out in order to make sound management decisions,” Wahl said. “Some of the pressing questions that we have are how many black vultures do we have here in Indiana, where are the birds located, how and where is conflict occurring, and how effective are different approaches to managing black vulture problems.

The aim of the research is two-fold. First, they are looking to see what causes some black vultures to become aggressive predators of livestock, instead of simply scavengers. Second, they are looking to learn signs that can determine whether an animal has been killed by vultures or simply scavenged, an important piece of evidence for livestock producers filing claims to the U.S. Department of Agriculture’s indemnity program hoping to recover compensation for their losses.

In order to achieve its goals, the research team is requesting the assistance of livestock producers through an online survey and also with the donation of calves believed to have been killed by black vultures. The qualtrics online survey is available now and will take only 15-20 minutes to complete. The survey is anonymous and data collected with be presented only in summary form and not via individual responses.

MyDNR Newsletter, Indiana Department of Forestry and Natural Resources (IDNR): Indiana residents are more likely to see coyotes during wintertime, but sightings are no cause for alarm. Coyotes become more active during winter as young coyotes leave their families to find a new home and coyotes begin breeding. Coyotes may look larger than they are due to their thick winter coats, but the average coyote only weighs 20-30 pounds.

General characteristics

• The coyote closely resembles a German shepherd dog in height and shape but it carries its tail below the level of its back instead of curved upward and is generally half the weight of a German shepherd.
• Coyotes have a long slender snout and large, pointed ears.
• The upper body is a grizzled gray or buff, with a reddish brown or gray muzzle and legs. The belly is white, cream-colored or reddish yellow.
• The coyote has a bushy tail, which it carries below the level of its back.
• Coyotes average 25 pounds (ranging from 20 to 50 pounds), and they measure 40 to 50 inches long from nose to tail tip.
• Coyotes are elusive and normally avoid humans.
• They can be active day or night, but are typically most active at dawn and dusk.
• The coyote communicates by barking, yipping and howling.

Distribution and abundance

Coyotes are present in all sections of the state. There are records of coyotes in Indiana as early as 1816, though they likely inhabited Indiana well before that time. Bounties were in place in Indiana on coyotes from at least 1849 through the late 1960s. Despite this persecution by early European settlers, coyotes persisted in Indiana. Historically, coyote populations were limited in range to the prairie regions of the state, and expansion may have partially been limited because wolves suppress coyote populations, and both red and gray wolves were once abundant in Indiana. However, with the eradication of wolves and conversion of habitat to farmland, coyotes have been able to expand and adapt to new habitats.  Statewide coyote abundance has slowly increased as coyotes continued to expand into previously unoccupied habitat.  Today, coyotes occupy all of Indiana, no matter the habitat type or amount of development.

Leaning trees can be a risk to neighboring property owners.

Purdue Landscape Report: I hear this complaint or issue more frequently, “what can I do about the neighbor’s tree?” or “my neighbor just butchered my tree!”.  Often, we see issues with a neighboring tree that may threaten safety or appears to be an elevated risk.  For example, from the view of your window, you see your neighbor’s tree dropping dead branches all over your driveway. Or, you can’t see a favorable view at all because of that tree or unruly hedge. Or you are certain that the neighbor’s tree will eventually fall onto your garage.

Before you take any action, establish ownership of the tree, and find out if you have rights to work on the offending vegetation. Otherwise, it can land you into a contentious legal situation.

Some questions to consider include:

When tree limbs or even the trunk of the tree crosses property line, are you within your rights to prune or remove it?

Check with local government websites for property maps which can help identify boundaries.

Boundary laws vary with every state. Often the boundary lines are uncertain or assumed based on local information. However, in contentious situations that may result in major modifications to a tree, it is advised to get a survey to establish exactly who owns the tree.

Rights are determined by who owns the tree. Check with your town, city, county and state municipalities for regulations about trees and property lines. The rights and responsibility for care and maintenance of trees are assigned to its owner, and ownership is determined by the location of the tree’s trunk. If the trunk is located entirely on the neighbor’s land even if its limbs or branches overhang onto your land, the neighbor is the tree’s owner. The neighbor has the sole right to preserve the tree or cut it down. This is true regardless of the neighbor’s motivation or the impact the tree removal would have on your land.

An ISA certified arborist can provide mitigation options that are best for the tree and helpful for the tree owner.

It is always best practice and considerate to first ask your neighbor if you can arrange to have it removed or pruned. They might actually appreciate it.

When tree work is required to remove or prune the tree and neighbor conflict exists, have a qualified tree care provider determine the work specifications on exactly how the tree issue should be mitigated. It is usually a bit more complex than simply stating, “cut limbs back to property line.” The work order must reference the ANSI A300 tree pruning standards to assure the procedures being proposed take into consideration the tree’s future health. Ensure that your tree care provider has a copy of their current liability insurance policy on hand. Check their references as well, not all tree care companies are guaranteed to provide the best results for you or your tree.

The best advice is to hire a tree care professional with the experience, expertise, and equipment to assess and safely prune, remove or otherwise care for your or your neighbors’ trees. Search for a tree care provider in your area. Also, consider hiring an ISA Certified Arborist which can be found here.

According to most attorneys, open-minded communications with the neighbor can result in an acceptable resolution for any situation. This will help to avoid contentious, expensive, time consuming, and unpredictable lawsuits.

Question: Can tree roots cause damage to a home’s foundation?, Got Nature? Blog, Purdue Extension – Forestry and Natural

Lindsey Purcell, Urban Forestry Specialist

The Nature of Teaching, a Purdue Extension signature program, was honored as the third place finisher in the central region for the Environmental Education Award presented by the National Extension Association of Family and Consumer Science (NEAFCS).

Question: Can tree roots cause damage to a home’s foundation? I have a 3’ in diameter pin oak tree that is within 10 feet of my house. A certified arborist took a look at it and said that he would like to use an Air Knife to expose the roots near the foundation (a walkout basement) to determine if the roots are causing damage and/or need to be pruned, or whether the tree needs to be removed since it is situated too close to the house. Before I spend $500 for them to use the Air Knife, I wondered if you thought it would be worthwhile or not necessary.

Answer: Tree roots can damage a house foundation, with an invitation to do so. Tree roots are very opportunistic and will only grow and penetrate where it is easiest to grow such as friable soils and mulch. Typically, when roots encounter solid, impervious surfaces such as pipes, sidewalks, curbs and foundations, they are redirected laterally or up and over. However, if there is a breach or a crack nearby, they can and will exploit those voids in search of moisture. Such as sewer pipes aren’t damaged by the roots, they are just very capable of finding those leaks and moving into the moist and often nutrient-rich pipe.

Roots normally grow horizontally and not very far beneath the soil surface. Sometimes when roots encounter the looser backfill soil near the foundation, they can abruptly start growing down. You may be able to locate these roots, if they exist, by excavating a foot or two down within a few feet of the foundation. If you find a suspect root, cut it off. Unfortunately, in some cases excavation down to the base of the foundation may be necessary. This may have to be done anyway to repair and stabilize it. Cutting the roots should prevent future problems, especially if a root barrier is installed to prevent re-growth.

September IDNR Wildlife Bulletin Newsletter: Indiana DNR is conducting targeted surveillance for chronic wasting disease (CWD) surveillance in northwest and northeast Indiana during the 2020-21 deer hunting season. Hunters may voluntarily submit samples for testing at select fish & wildlife areas (FWAs) and state fish hatcheries (SFHs) throughout the hunting season. Deer heads can be dropped into designated coolers at select FWAs and SFHs or hunters may make an appointment for their harvested deer to be sampled by a biologist during office hours. The 2020-21 sampling locations and their hours of operation are listed on the website. Indiana DNR biologists will intensively sample hunter-harvested deer at local businesses in the surveillance areas during three weekends: Nov. 7-8, 14-15, and 21-22.

Hunters interested in testing a deer for CWD that was harvested outside the CWD surveillance areas may take their deer to select FWAs and SFHs as well. Alternatively, hunters may independently submit their deer to the Purdue Animal Disease Diagnostic Lab (ADDL) for testing for a fee. Hunters should complete the submission form and follow the shipping instructions on Purdue ADDL’s website.

Hunters who submit a deer for CWD testing will receive a Deer Management Partner magnet and metal tag reminiscent of Indiana’s historical deer harvest confirmation process.

For more information, please visit the Indiana Department of Natural Resources website.
