May IDNR Wildlife Bulletin Newsletter: Do you know what to do if you find an injured wild animal? The first step is determining if it is actually injured. Clear signs of distress include:

• Bleeding or clear signs of injuries such as bruises, cuts, punctures or broken bones
• Looks thin, weak, cold or soaking wet
• Signs of diarrhea
• Flies, fly eggs, maggots, ticks, lice or fleas have infested the animal

If a wild animal shows any of these signs and is unable to move or run away effectively, it may be time to call a licensed wildlife rehabilitator (PDF) for help. You can find a list of wildlife rehabilitators on IDNR Orphaned & Injured Animals website.

Please note that the Indiana DNR does not provide services for injured or orphaned wildlife. We rely on licensed wildlife rehabilitators to assist with these situations.

Across the globe, most vulture species are declining dramatically. This is concerning because vultures provide valuable ecosystem service by cleaning the environment of carrion, thereby reducing disease risk for humans and livestock. In contrast to most other vulture species, populations of the American black vulture have grown and expanded into new areas during the past several decades. This has created the potential for conflict because black vultures have been documented to kill weak or newborn livestock.

The Purdue Forestry and Natural Resources’ research team seeks to better understand vulture ecology to inform conservation of other vulture species, as well as to understand how best to minimize conflict between vultures and producers by investigating what factors place some farms at greater risk.

What to do if you lose an animal:
• Take lots of pictures from every angle.
• If scavengers are around, move the carcass somewhere they cannot access.
• Call or text Marian Wahl at (317) 647-5294 as soon as you can. Marian is a graduate research assistant working with Pat Zollner, professor of wildlife science.

Thank you for your help as we gather livestock loss due to vultures in the states of Indiana and Kentucky.

IN-PREPared: The American Society of Agricultural and Biological Engineers (ASABE) recently awarded the Purdue Rural Emergency Preparedness program (IN-PREPared) with The Blue Ribbon Award for their efforts to provide disaster and emergency resources and training to Indiana residents, especially through their specially created website.

Founded in 1907, ASABE is an educational and scientific organization dedicated to the advancement of engineering applicable to agricultural, food, and biological systems with members in more than 100 countries.

Shawn Ehlers, Assistant Clinical Professor of Agriculture and Biological Engineering and IN-PREPared Program Leader said many members of ASABE are involved with Extension outreach in their focus area.

“Part of ASABE’s Pillars of Practice involve ergonomics, safety and health, as well as education outreach and professional development,” Ehlers said.

“The Blue Ribbon Awards are the society’s way of acknowledging impactful contributions and this year, IN-PREPared was chosen to receive the honors for Extension Websites and its impact on the community,” he added.

Previous university efforts to serve Extension educators, rural communities, and first responders stemmed from three primary sources which included Purdue Agricultural Safety and Health Program (PUASHP), Purdue Extension, and the National Extension Disaster Education Network (EDEN) materials and training. Each entity produced and distributed valuable resources and training, but the separate efforts lacked cohesiveness.

“The IN-PREPared program and website provide a publicly accessible and unified home for appropriate resources, and also serves to enhance the visibility, awareness, and usage of programming and resources offered by state or federal government agencies and non-profit organizations dedicated to rural emergency preparedness and response through partnerships and resource sharing,” Ehlers explained.

Ehlers also said this new program, launched in August 2019, was prompted by the need to be instrumental in bringing relevant material together on emergency preparedness for their specific audience – a key he believes to the successes of the IN-PREPared program.

“The past several months have demonstrated how our society can adapt to a situation to meet the needs of communities across the state and nation, because making informed decisions is at the heart of preparing for unexpected or emerging circumstances,” he said.

IN-PREPared has categorized content to be conveniently accessed by users with topics that include weather events, disease prevention (a COVID-19 specific resource page), rural specific hazard response, and links to online trainings, and PREP-Notes which are used by Extension Educators, teachers, and volunteers to craft news releases and share information on multiple platforms.

Other cohorts in this award-winning effort include former extension educator and staff member at the Indiana State Department of Agriculture Ed Sheldon, who assisted in the overall resource development and website management. Sheldon also works with the National AgrAbility Project, the Ag Vets program, and IN-PREPared.

Bill Field, Professor of Agricultural and Biological Engineering, leader of the Purdue Ag Safety and Health Program, and Project Director for the National AgrAbility Project, and served as the co-developer and instructor of three Homeland/Agrosecurity graduate level courses at Purdue.

“Above all else, IN-PREPared is focused on collaborating with experts in our federal and state agencies, as well as universities and non-profits so we can bring collective knowledge to our rural Hoosiers so they can be “PREPared” for the unexpected—not possible without the reach of the Extension system in all 92 Indiana counties,” Ehlers emphasized.

Purdue Landscape Report: Homeowners can easily become injured – often fatally – while attempting to trim trees near overhead electrical wires. Though it is tempting to try to save money with this “do-it-yourself” approach, the potential for electrocution is not worth the risk. It is important to recognize when to call a professional arborist.

Terrible accidents can happen when a homeowner uses any type of cutting tools and/or ladders when attempting to trim backyard trees and shrubs. Overhead wires are often unnoticed and is touched by directly or indirectly, causing injury or death.

Examples include:

• A homeowner climbed a ladder to trim a tree branch that was dropping leaves into his above ground swimming pool and causing a nuisance. A branch came in contact with the power line, shocking the man with a jolt of electricity and sending him into cardiac arrest. He fell 20 feet to the ground but was revived by medics at the scene.

• MATTHEWS, N.C. — A man trimming trees in a neighborhood was shocked Wednesday morning after a limb fell on power lines, authorities said. Nearby resident Margie Owens knows the man and said he does odd jobs around the neighborhood. According to officials, after the limb fell from pruning, the tree continued to be energized by the power line, leaving the man stuck.
• A Charlotte County man was electrocuted trimming trees in a backyard. The victim was part of a landscaping crew and came in direct contact with a utility line.

Preventable Accidents
Tree limbs can conduct electricity. When trees grow near overhead wires, they can contact the wires and become energized. Trees and wires are dangerous, full of electrical power that can injure or kill humans. How do we know which lines are energized?  WE DON’T! Assume all are carrying dangerous electrical current and should be avoided when working around them.

A common house switch carries 120 volts, but the electric flow is usually limited to 10, 15 or 20 amps. A common “house drop” (service wire) contains 240 volts and up to 20 amps or more. Given the right set of circumstances, even the shock a person gets from a common light switch can kill, but at the same time, it is easier to break electrical contact while standing inside a house. If a person is climbing a ladder or is in the tree, it may be more difficult to break contact with the energized wire. This means that the service line over a typical yard could easily kill a person.

 

Here are a few tips to avoid trees in wires:

• Look for power lines before pruning trees and large shrubs. If lines are anywhere near the tree within 10 ft. don’t attempt any tree work. Tree care professionals have the training and equipment needed to perform these tasks safely.
• Never climb a tree in order to prune it. Even if the wires aren’t currently touching the tree, remember that the tree’s branches will shift once you begin climbing or removing limbs.
• Don’t move ladders or long-handled pruning tools around the yard without first looking up. Always read and heed ladder-use safety labels.

Find a professional
Be sure to always hire an insured, tree care professional, preferably and ISA Certified Arborist with the experience, expertise, and equipment to safely take down or prune trees in wires. Require proof of liability insurance to protect yourself as well.

Another easy way to find a tree care service provider in your area is to use the “Locate Your Local Tree Care Industry Association Member Companies” program. For more information refer to the publication Trees and Utilities at the Purdue Education Store.

Find a certified arborist in your area by going to Trees are good website.

Purdue Landscape Report: Now that we’ve reach midsummer, many people tending to small plants and bushes may notice small odd round grey objects attached to their plants that are made by potter wasps. Do you need to do anything about them? Do these nests help or harm your plants? And are they dangerous to people?

What do they look like?
You are more likely to notice the nests of potter wasps than the adults. Potter wasp nests often look, like the name suggests, like a small grey pot (figure 1). They are rounded with a small opening that looks like the neck of a vase and are about the size of a cherry tomato. These wasps will attach their nests to many different surfaces but tend to prefer plant and bush stems. Potter wasp nests are often found hidden behind foliage in bushes.

Potter wasp adults come in a variety of colors but all of them look like small hornets. The most common species found in Indiana are mostly black with pale yellow bands around their abdomen (figure 2).

How do they help plants?
Each “pot” that the wasps build is a tiny nursery for a single wasp. Adult potter wasps lay a single egg in each “pot” and then fill it with paralyzed caterpillars and small beetle larvae. When the wasp egg hatches it has all the food it needs to develop into an adult contained in the pot. Each wasp does a small part to keep down the number of caterpillars in the landscape which can reduce the amount of leaf damage on nearby plants.

Will they hurt me?
Probably not! Potter wasps don’t defend their nests and are generally not aggressive. Unless you actively try to bother them they will probably not bother you. If you need to remove one of their nests, you can simply pull it off the plant or object that it’s attached to. However, since they help with pest control, you may want to either leave the nest be or relocate it to a different section of the landscape.

Does anything else look like the “pots”?
Although the “pots” have a very distinct shape there are a few other things that could be confused with them at first glance. Mantis egg masses (ootheca) and some types of galls are both about the same size as potter wasp nests and also often grey. However, they both lack the vase neck-like opening that potter wasp nests have.

What should I do if I see one?
Let it be! Since these wasps rarely sting and help keep caterpillar populations down leave them alone so that they can continue to act as biocontrol agents. If you think you’ve seen a potter wasp or one of their nests and would like help identifying it, take a picture and either upload it to a community science project like iNaturalist or send a picture to the author of this article.

Across the entire United States, and into Canada and Mexico, coyotes can be found just about everywhere. But what would you do if you encountered a coyote while out all alone? Would you feel comfortable knowing how to act? How about how to keep your children or pets safe in such an encounter? 

In our June 11th Ask the Experts series, “Coexisting with Coyotes,” Purdue researchers Brian MacGowan and Bee Overbey talked about these topics and more. As a keystone species in their ecosystem, coyotes play an extremely important role in maintaining population levels of other animals, such as deer, rabbits, raccoons, and voles. By keeping these populations in check, plants and trees are better able to grow, and this creates greater biodiversity and healthier habitat. And coyotes are not going anywhere! This resilient, intelligent species has learned to adapt around humans and every change that we bring.

Check out the video below to learn more about coyotes, how important they are to the lands where they are found, and tips on how to coyote-proof your property and keep yourself and your loved ones safe in coyote encounters. By working together, we can easily and safely coexist with this vital native species.

Question: We live in eastern Tippecanoe county and have a couple of adult squirrels that seem to be sick. They act like they are drunk — falling over frequently. We have two apple trees in blossom, and they come and nibble on fallen branches/blooms. As they sit on their hind legs to eat, they fall over on the ground like they are dead. Then after a few minutes/flip around and get up again, only to fall over “dead” again. This has been going on for a few weeks. We also have a baby that is not afraid of people – does not run away from me or our dog. This baby appears to have missing hair/or possible mange? We also had a raccoon in early March that came toward my husband in the yard – was not afraid of him. It did not appear rabid, but did not run away either. We do have several bird feeders, one of which squirrels and chipmunks sit on and eat the bird food. Is what they are eating making them “sick/drunk” or is this something else? I googled and found possible raccoon roundworm? What do YOU think this is — and could these cases be related? How should I dispose of any dead animals, and should I be concerned for us or our dog?

Answer: What you describe could be a number of wildlife diseases. The clinical signs of many of these diseases are often similar and infection can only be determined through specific examinations, tests or lab work. It may be canine distemper. Both squirrels and raccoon can carry canine distemper. The disease is spread by direct contact with body fluids or droppings of an infected animal. Humans cannot get distemper. However, it may also be another disease or a separate disease for each species. Your choices are really to 1) do nothing or 2) contact a wildlife rehabilitator (see below). In Indiana, wildlife rehabilitators have necessary state and federal permits to house and care for sick or injured wild animals. No federal or state agencies will provide care for sick and injured animals.

Since wild animals can carry diseases that are dangerous to people, direct contact with wildlife is discouraged. Just as the case with people, you can’t tell if an animal is sick just by looking at them. Expression of clinical signs of diseases are not the same for every animal. It may also take a period of time for clinical signs to present themselves. An animal that appears perfectly healthy may have a disease, and may be able to transmit the disease.

I could find no specific guidelines for the disposal of dead wild animals. The Indiana State Board of Animal Health lists allowable methods of dead animal disposal, but these do not apply to wildlife, which they specify as creatures not under someone’s care. This is guidance on the DNR website for:

Dead Birds: “According to Indiana State Department of Health guidelines, if you need to dispose of a dead bird, do not handle it with your bare hands. Use gloves or a plastic bag turned inside out over your hand to pick up the bird and dispose of the bird/bag in the trash. You can follow these recommended disposal procedures regardless of the cause of death, if testing is not available.”

Dead Bats: “Do NOT pick up a bat with your bare hands. Any wild animal can carry disease, therefore precautions should be taken if an animal needs to be moved. Wear heavy-duty leather gloves and scoop up the bat with a shovel or container. If the bat is alive move it to a tree branch, away from nearby buildings if possible. To dispose of a dead bat, scoop it into a plastic bag. Place it into another plastic bag, close it securely, spray with disinfectant, and dispose of it in your trash.”

The Purdue Extension and Illinois-Indiana Sea Grant Rainscaping Education Program was highlighted in the National Oceanic and Atmospheric Administration’s Education Accomplishments Report (pdf) for fiscal year 2019.

This report highlighted all of NOAA’s greatest accomplishments related to education in five main goal areas: science informed society, conservation and stewardship, safety and preparedness, future workforce and organizational excellence.

The Rainscaping Education Program was featured in the Conservation and Stewardship section of the report. The Purdue Rainscaping Education Program offers state-wide training for Purdue Master Gardeners, conservation agencies and organizations, stormwater professionals and landscape companies and consultants. Through two-day workshop sessions, the program provides an introduction to rainscaping and rain gardens, including segments on site selection, plant selection, garden design, installation, maintenance and community engagement.

“It is wonderful to have the innovative and collaborative work of the Purdue Rainscaping Education Team recognized for its efforts,” Kara Salazar, assistant program leader and extension specialist for sustainable communities said. “The team has been working together since 2013 to develop and implement the interdisciplinary program addressing the need for community education on sustainable landscape practices to prevent polluted runoff.”

Salazar and John Orick, Purdue Master Gardener State Coordinator, are co-leads on the project. View  the full Rainscaping Team.

The featured segment on the Rainscaping program from the NOAA annual report is below.

Unmanned Aerial Systems and Burn Management Strategies

On September 19, 2019 a controlled burn was conducted on the Doak grassland and forest property, owned and managed by the Department of Forestry and Natural Resources at Purdue University. Burn events such as this one present a unique opportunity to demonstrate how UAS can be utilized as an effective tool to both monitor the burn events in real time, but also to effectively gather data before and after the burn to map and better manage vegetation. This collection of maps, videos, and images provide a narrative on how UAS can be used as an effective tool in controlled burn management practices. Beyond controlled burns, the story should demonstrate how UAS can be used to better monitor and inventory other disturbance events, whether they are planned or unexpected.
