deerSeptember 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.

Purdue Landscape Report: Have you noticed large, messy webs on trees? You may have seen a colony of fall webworms. These caterpillars hatch in mid-July but tend to become more noticeable as the summer progresses. They often eat branches bare of leaves but are they a threat to tree health?

What do they look like?

Fall webworms are small, fuzzy pale-yellow caterpillars (figure 1) that build large, conspicuous white webs in trees in the late summer (figure 2). Their webs stretch over tree branches and grow over the course of the summer. When disturbed, the caterpillars will violently thrash back and forth in a bid to ward off predators.

Fig2. Trees will often have multiple fall webworm webs on them. This photo shows a typical number of webs for a large tree. Notice that the webs tend to be on the ends of branches and that the leaf damage is concentrated close to each web. Photo by Ken Gibson.

What kind of damage do they cause?
Fall webworms eat the leaves of many species of deciduous trees and bushes. This damage occurs late in the summer shortly before the trees normally drop their leaves for fall. Therefore, fall webworms very rarely do serious damage to trees. In most cases the trees will grow their leaves back the following spring. On rare occasions, a tree that is already highly stressed may be further weakened by fall webworm damage. However, most trees, even heavily infested trees, are minimally affected and show no signs of damage the following spring.

Do they need to be managed?
Fall webworm damage generally looks much worse than it is. In general, trees only need to be managed for fall webworm if the owner is concerned about aesthetics. In that case, the easiest means of management is pulling the web off the tree by hand and putting it in a bucket of soapy water or freezing it. Some people may be sensitive to the caterpillars’ hairs so gloves should be worn to prevent contact.

In cases where the webs are too high up to be reached, they can be managed through insecticides. Further instructions can be found here.

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.

vultureFlyerAcross 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.

ASABEIN-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.

Utility service providers can help select a tree which is compatible with nearby lines and reduce the need for excessive pruning to maintain safety and reliability

These powerlines could be “energizing” the tree creating a potential shock hazard for anyone touching the tree. Notice the burning on the new growth.

Trees growing into utility lines should be pruned by a qualified arborist.

 
 
 

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.
