Morning AgClips — You have probably seen a cartoon or stereotypical TV show where someone sees a mouse and says, “Eek, a mouse!” Mice and rats around homes and farmsteads can be a problem. Have control methods improved on the typical snap trap of 50 years ago? In short, they have.

The adult house mouse is about 5½ to 7½ inches long, including the 3–4-inch tail. Norway rats are much larger, from 13 to 18 inches long, including the 6–8½-inch tail. According to the Internet Center for Wildlife Damage Management (ICWDM), mice eat many types of food but prefer seeds and grain. They sample new foods and are considered “nibblers.” Foods that are high in fat, protein, or sugar (e.g., bacon, chocolate, butter, nuts) may be preferred, even when grain and seeds are present. An individual mouse consumes about 1/10 of its body weight each day and up to 8 pounds per year. Mice contaminate far more food than they consume through their urine and feces.

In homes and commercial buildings, mice may feed on stored food items and pet foods. They contaminate food with their urine, droppings, and hair. On farms, they damage structures that store feed and equipment. Mice often act as reservoirs or vectors of diseases, such as swine dysentery, leptospirosis, salmonellosis, and other diseases.

ICWDM suggests several preventive and control methods people can employ. Proper sanitation around structures is helpful. This reduces sources of food, water, and shelter. Rodent-proof construction is recommended, along with proper storage and disposal of refuse and garbage. They indicate that ultrasonic frightening devices are generally not effective. Repellants and toxicants are options to consider. Trapping devices, such as snap traps, cage or box traps, and glue boards, may also be considered for use.

Invasive species are any plant, animal, insect or plant disease not native to a specific location that can cause harm to the environment, impact the diversity of native species, reduce wildlife habitat or disrupt important ecosystem functions.

Why should you care about invasive species? Invasive species limit land use, degrade natural resources and inhibit recreational pursuits such as hunting, fishing, bird watching, and foraging. They also negatively impact fisheries, agricultural and forestry industries, destabilize soil and alter water resources. Invasive species also out compete natives and are costly to control with estimates showing that the U.S. spends $137 billion/year to control/manage invasive species.

As spring approaches, many invasive plants will begin to leaf out in woodland areas. Spring is a good time to stop them in their tracks so they don’t overtake native plants, affect water availability or damage the quality of soil among other potential impacts.

Here are some resources to help you identify various invasive plants in woodland areas near you, to know when to report them and also what you can do help control their spread.

When and how do I report an invasive species?
The Purdue Invasive Species website will help you identify invasive species and explain how to send in your findings. If you notice something is killing an otherwise healthy stand of trees or shrubs, you will want to identify it and report it if it is on the invasive list. If you see a plant that is taking over an area where it doesn’t belong, you will want to identify it and report it if it is on the invasive list.

Wild Bulletin, Indiana Department of Natural Resources (DNR) Fish and Wildlife: Have you seen wildlife showing odd behaviors or signs of disease? DNR encourages you to report them using our online Sick or Dead Wildlife report system. DNR is especially interested in recurring deaths of wildlife in the same location over a period of time, deer showing signs that may indicate chronic wasting disease or epizootic hemorrhagic disease, or incidents involving threatened or endangered species.

Indiana DNR’s Sick or Dead Wildlife Reporting System collects information about wildlife that appear sick or appear to have died without an apparent cause (e.g. do not use this form for predation or roadkill). Reports of incidents involving common species and single animals are useful to help us understand baseline levels of sickness and death in wildlife populations.

Your reports help us track wildlife health over time and detect potential disease outbreaks in the state. Visit the Sick or Dead Wildlife Reporting webpage to learn more.

Tax preparation time usually brings with it questions about what is deductible, how to report this income and what you can do to save on your taxes in the future. Fortunately for woodland owners, there are several excellent resources available to help you find some guidance.

A national site addressing tax issues for woodland owners is the National Timber Tax Website. This site provides updated tax tips for the 2024 filing year, as well as many guides and references to help you effectively plan a tax strategy for your property.

The first link you will see on the National Timber Tax website is the recent timber tax tips by the U.S. Department of Agriculture (USDA), Forest Service:
Tax Tips for Forest Landowners: 2024 Tax Year (pdf 176KB)

Purdue Forestry and Natural Resources Extension offers some publications covering taxation issues for timber sales and tree planting.
How to Treat Timber Sale Income
Determining Tax Basis of Timber
Financial and Tax Aspects of Tree Planting

If you sold timber or planted trees for timber production last year, the references above may help you understand your options and possibly provide some tax savings.

Familiarizing yourself with the tax treatment of timber sales and tree plantings may help you more effectively plan for future tax returns.

When do you need to discard your real Christmas tree? What options are there in disposing the tree?
Check out these tips from our Purdue experts:

Lenny Farlee, Purdue Extension Forester with Forestry and Natural Resources, in interview with the WLFI news team shares the first steps is to remove all decorations. “Several municipalities here in the area will either take the trees for mulching or composting. So if you don’t want to fool with the tree anymore, that’s a great option. You can just take it to the curb, or certain locations, and they’ll take care of it for you and it gets reused or recycled into usable material,” explains Farlee.  Choosing to keep the tree in your backyard is a great wildlife friendly option. Lenny shares how important it is to remove your tree in a timely manner to avoid any fire hazards in your house. The video explains on how you can test your tree to see if it should be discarded. See video and full article for more options: Options for Getting Rid of Real Christmas Tree, wlfi.com.

John Woodmansee, Purdue Extension Educator-Agriculture Natural Resources (ANR), also shares tips in the Purdue Extension article Recycle Your Christmas Tree. If you have permission and/or have access to a private pond you can discard your tree in the pond to improve fish habitat.

A real Christmas tree is an important part of a holiday celebration for many Hoosier households. Consumers have several choices for purchasing a real tree, including pre-cut trees at retail outlets or seasonal sales locations, choose-and-cut trees at Christmas tree farms, or even live trees that can be replanted after the holidays. Purdue Extension offers two publications that can help you select and care for your tree: Tips for First-Time Buyers of Christmas Trees provides advice and direction on how to set up and care for your tree to improve safety and enjoyment. Selecting an Indiana-Grown Christmas Tree provides details on the characteristics of different species of real Christmas trees available in Indiana, as well as care instructions for cut and live Christmas trees.

Pre-cut real Christmas trees are available at many retail outlets like garden centers, supermarkets, or seasonal sales locations. If you are looking for local choose-and-cut Christmas tree farms you can consult local media and advertising outlets or the Indiana Christmas Tree Growers Association. Some garden centers and Christmas tree farms may also offer live trees for sale.

If you are considering growing your own Christmas trees for personal use or sale, the Extension publications Growing Christmas Trees and A Choose-and-Cut Pine and Fir Christmas Tree Case Study outline economic and management considerations for growing Christmas trees.

Check out the Ask an Expert: Holidays in the Wild as the experts answer questions regarding Christmas trees along with wildlife you may see while you walk in the woods this winter. In this Ask an Expert video they share resources about picking a real Christmas tree and how to access real trees locally in Indiana as well as collecting decoration materials like cones, seed pods and nuts form the wild for crafting and decorating. They also discuss how you can provide habitat and supplemental food for wildlife using Christmas trees and wreaths before, during and after the holiday season.

MyDNR, Indiana’s Outdoor Newsletter: Donate your harvested deer to feed hungry Hoosiers. In Indiana, you can enjoy a great day hunting and also help Hoosiers in need. In fact, one donated deer can provide 200 meals for a Hoosier family!

Follow these simple steps:

1. Enjoy a deer hunting experience.
2. Harvest a deer.
3. Drop off the field-dressed deer at a local participating processor.
4. Processing fees are paid for by Hunt for Hunger (at no cost to you).
5. The processor creates healthy venison burgers to distribute to food banks.

This is a part of the program Indiana Hunt for Hunger (also known as Sportsmen’s Benevolence Fund).  The Indiana Department of Natural Resources launched this in 2008 to provide an easy way for hunters across Indiana to help hungry Hoosiers in need. Since its launch, the program has grown across the state to collect thousands of deer donations, providing hundreds of thousands of meals for Hoosiers.

For more information, visit the Hunt for Hunger page.

Purdue Landscape Report: Dieback and canker diseases caused by Botryosphaeria, Sphaeropsis, Diplodia and other closely related fungal pathogens are exceptionally common on woody landscape plants. This group of diseases are often referred to collectively as Botryosphaeria diseases and this article will follow that convention to discuss them as a group. Examine any mature oak tree long enough and you’re likely to find at least some stems dying due to Botryosphaeria. Check the base of dying stems of cranberry bush viburnum and you’re likely to find a Botryosphaeria canker. Look closely at sunken cracked stems and dieback on redbud and, you guessed it, more Botryosphaeria.

Botryosphaeria is opportunistic and is often seen killing individual branches that have been wounded or attacked by other diseases, providing an entry point for the fungus. (Fig 1) Stress factors like drought, freezing or defoliation due to disease or insect attack increases susceptibility to infection, and reduces plant defenses so that existing infections often move faster down the stem. However, wounds are not required for infection. In susceptible trees and shrubs, the fungus may attack the smallest twigs and later spread to larger branches where they cause cankers.

Symptoms:
Discoloration and death of leaves on individual stems may point to Botryosphaeria canker at the base of the dying stem (Fig 2). As the canker girdles a stem, the portion of the stem above the canker gradually dies. Smaller twigs with immature bark may become discolored as the pathogen spreads. Symptoms may vary depending on the plant species infected. In many cases the infection fails to completely encircle the stem, resulting in stems with half necrotic and half living stem tissue (Fig 3).

Botryosphaeria cankers usually cause bark to be cracked, sunken and discolored (Fig 4). Fruiting bodies of the fungus appear as pinhead-sized black specks embedded in the bark, which may be raised in small bumps covering the cankers.

Management:
Prevention of infection depends mainly upon avoiding unnecessary wounding and minimizing environmental stresses that induce susceptibility. Avoid allowing trees and shrubs, especially those recently transplanted, to become drought stressed. Keep plants in good condition and in moderate growth. Avoid high fertilizer rates that induce rapid, succulent growth that may be more susceptible to infection.

Prune out and destroy any dead branches at least six inches below discoloration in the bark or sapwood. Be sure to clean pruning tools with a disinfectant after working on infected plants.

Fungicides have not been effective at preventing infections, and once the fungus is inside the wood fungicides can’t touch it, so they are generally not recommended in the landscape.

Avoid using highly susceptible plants, such as Viburnum trilobum or Salix spp., in drought prone sites.
