Do you have a sudden urge to jump in the tractor and mow your fields, field borders or road ditches?
You might have RMS.

Do you enjoy spending your weekend in the cab of the tractor with a mower in tow in search of places to mow across your property?
You might have RMS.

Do you get queasy at the sight of a “weedy” unkempt field?
You might have RMS.

What is RMS you ask? RMS stands for Recreational Mowing Syndrome, a condition that afflicts many rural landowners during the summer months. And if you answered yes to any or all of the questions above, then you have RMS.

What is it?
RMS is the sudden urge many landowners get to ‘clean’ up their property by mowing the ideal fields, field borders, and road ditches around the farm during the summer months. While a mowed field may look attractive in the eyes of a landowner, in the eyes of wildlife, this is a serious problem.

These prime mowing spots provide habitat for a suite of birds, mammals, herpetofauna, and pollinating insects that inhabit our rural landscapes. Many of these species are actively nesting or raising young in these areas during peak mowing season – April through September. And the weeds coming up in these fields like common milkweed, tall ironweed, common ragweed, and many others provide food and cover for wildlife.

How to treat it?
The easiest way to treat RMS is by going cold-turkey – park the tractor for the summer. If you are not ready to give up mowing all together, then restrict your mowing to just the lanes around the fields, instead of the whole field. If you are ready to give up mowing, but still want to enjoy time in the tractor, try these options.

Instead of hooking up the mower, hook up the sprayer and go control some invasive species on the property, like bush honeysuckle, autumn olive, or sericea lespedeza. Or try hooking up the disk and disking around the field to prepare firebreaks for a late summer or fall prescribed fire.

You can still spend time on the tractor during the summer months without eliminating wildlife habitat through mowing. In fact, you can improve it!

Next time you look at your window and see a “weedy” field, don’t cringe and give into the urge to mow it. Instead, just smile and listen to all the quail whistling, songbirds singing, and bees buzzing in the habitat you improved by not mowing.

The Invasive Terrestrial Plant Rule was signed by Governor Holcomb and published on March 18, 2019. the rule goes into effect 30 days after publishing, so it will be effective in April.

The Rule States that a person must not:

• sell, offer or grow for sale, gift, barter, exchange, or distribute a species;
• transport or transfer a species;
• introduce a species

with respect to the 44 invasive plant species (see full list in the Landscape Report).

Note: Selling, offering, distributing and transporting doesn’t go into effect until April of 2020, so nurseries will have some time to sell down their stock. This is an important component of the rule to minimize economic loss to nurseries that grow and/or sell the few commercially available species that are on the list. Currently there is no mandate to eradicate existing plantings in nurseries, landscapes, or forested areas

To learn more about what an invasive species is, what damage they do, what Indiana is doing, and more please read the Landscape Report, Terrestrial Invasive Species Rule Signed by Indiana Governor.

This looks to be shaping up as a tough winter for us and our trees. Lots of snow and ice are predicted for the Hoosier state and this can be a challenge for our trees and shrubs.

After a heavy snowfall, protect your trees and property with these simple tips:

Do not shake limbs to try to remove snow or ice.
When you find your trees are bending or drooping as a result of ice or snow accumulation, your first instinct is probably to shake the branches or knock the weight off with a broom or something similar. This may cause worse damage or actually cause the branch to snap off. Stop right there! Healthy tree branches are flexible, so knocking off the accumulation of snow or ice accretion may cause them to “snap” back, potentially damaging their food and water transport system. The results of the damage may not be evident until next spring.

Trees that tend to suffer the worst damage as a result of snow and ice are upright evergreens, like arborvitae and juniper, and clump trees, like birch. And, when it comes to ice, age does not make a tree stronger; younger trees are better at actually overcoming damage in ice storms.

Hire a Professional.

Safely remove broken limbs.
Broken and hanging branches can be a threat to people and property. If a limb breaks off from the weight of ice or snow and remains in the tree canopy, have it removed and the remaining stub properly pruned to the branch collar as soon as weather allows. The tree will recover better when properly pruned. For undamaged limbs bending under the weight of ice or snow, don’t prune as a means of correcting the situation. Be patient. It takes time for wood fibers in the limbs to return to its natural position.

Always be mindful of walking or parking under branches loaded down by snow or ice as they may snap and fall, causing injury or damage. If a limb breaks and becomes entangled in power lines, notify your utility company immediately. Never approach a downed power line or a branch touching a utility line.

If there is substantial damage to your tree, have an arborist examine damaged branches and limbs for signs of weakness and injury for reparations. It is best to always hire an ISA Certified Arborist. To find an arborist in your area, visit the website, www.treesaregood.org

How can you help prevent ice damage to trees? Proper pruning is one way. Particularly important is the removal of poor branch attachments and weak branch structure in the tree, prior to winter. For more information on pruning, download the publication, Tree Pruning Essentials.

How do I remedy poor branching? Is my tree at risk of splitting, and how can pruning prevent that? Corrective pruning has many implications for tree structure, health, and longevity. Developing a strong, central branch structure in a deciduous tree is critical for preventing structural failure caused by storms, wind, and ice. This 8-page publication explains the problems resulting from a co-dominant stem structure and addresses pruning strategies for correcting poor structure.

People have been catching wild turtles and selling them as pets, leading to many species becoming endangered.  This is very dangerous for the health and survival of the turtle as well as being highly illegal in Indiana. We highly discourage you from taking turtles from their natural habitat and turning them into pets (or any animal for that matter). Here’s a list of reasons why it is not good to make a pet out of a wild turtle and what you can do if you see any turtle miss handling and turtle wrong doing.

Turtles DO NOT make good pets!

Reasons why turtles aren’t good pets:

• Turtles require time and money for proper care, and some species can live up to 50 years.
• Pet turtles do not like to be held and are loners; therefore, they can become boring pets for children.
• Turtles are cold-blooded and need a source of heat. They also require an ultraviolet light for proper growth and health.
  • Without this special light, many health issues arise such as metabolic bone disease.
• It is very important to know what kind of species you want and the care it needs before you acquire a pet turtle. Many need special food and tanks.
  • Each species has different feeding requirements, with some being strictly carnivores or herbivores. Map turtles, for example, have restricted diets that must include snails, aquatic insects and crayfish. Some species of aquatic turtles, such as the red-eared slider, map turtle and soft-shell, grow up to 12 inches long, requiring a large tank for swimming and basking.
• Land turtles need a large pen, with sufficient substrate, properly sized water bowl, a hide area, as well as heat. Some require more humidity than others.
• If you no longer want your pet turtle, you cannot release into the wild because it is not likely to survive.
  • It will have to find its own food, deal with the elements and deal with predators.
  • These once-captive turtles are also likely to transmit diseases to wild turtle populations.
• Turtles can carry salmonella bacteria.
  • The Centers for Disease Control and Prevention recommend that children, pregnant women, and persons with compromised immune systems avoid contact with reptiles to avoid getting Salmonella.
  • The DNR does not encourage the keeping of turtles as pets, but does allow it if the turtle species is obtained legally with a hunting or fishing license.

 

It is illegal to sell wild turtles

Many native, wild-caught turtles are still sold as pets, even though this practice is illegal in Indiana. The collection of wild turtles has caused many species to become endangered, especially when combined with habitat loss, water pollution and predators. Predators such as raccoons eat a large number of turtle eggs each year, and some species do not even breed until they are several years old, meaning that it can take many years for a population to become established. You can help protect Indiana’s turtles by helping to preserve turtle habitat, especially wetlands, through local conservation organizations or the Indiana Nongame and Endangered Wildlife Program.

Help our endangered turtle species and report any wrong handling, contact DNR Customer Service Center.

At different times of the year, I get questions about bats in structures.  Bats are a timely issue towards the end of summer because young bats will soon be able to fly.  Excluding bats from structures is limited to this time.  This process is typically called “venting” where access points (both in use and potential) are identified, most are sealed off, and the remaining points are fitted with one-way doors that allow bats to leave but not reenter. If only the opening they use is sealed off, they will simply use another entry point. Think of it this way – our houses have multiple points of entry, but you may only use one. You will use another if necessary.

Bats can make their way into a house in a number of ways – gaps between siding and chimney, gaps between roof sheathing and fascia board, etc.  New and old construction alike. Eliminating access to all of these small, potential points of access can be a challenge. The bodies of some bat species are as small as your thumb. Even though you don’t have an attic, there are still spaces inside a structure where bats can live.

Bats are one of the most difficult wildlife conflicts to deal with because of the nature of their habits. They can pass through extremely small openings, move throughout the inside of a structure, and often entre/occupy hard to reach areas. Bat exclusion is not an activity I recommend for most homeowners.  There is a skill necessary to find and seal all possible access points. Since most of these are located high above ground and accessing these points can require special ladders, lifts and other safety equipment.

Having bats in the attic isn’t simply a nuisance issue, but also can be a safety issue. Like Most wildlife carry diseases. With bats, histoplasmosis and rabies are the two that are the ones most concern for people with bats in their homes.  The Center of Disease Control (CDC) has good information on these and other diseases. Fleas that live on bats can also be vectors for disease. It is always a good idea to limit exposure to wildlife animals as much as possible. For bats, venting in the end of summer and fall and preventing reentry is a logical first step.

If you have bats and want to solve the problem now is the time to contact professionals who can help. Unfortunately, most nuisance wildlife control operators don’t do bat work because it requires specialized equipment and the difficulty of it.  Because of that, control will not be cheap for the customer.  Many people construct bat houses to attract bats. While beneficial, artificial bat houses will not attract bats from an attic.
