Wild Bulletin, Indiana Department of Natural Resources (DNR) Fish and Wildlife: Your contributions to the 2023 Turkey Brood Survey surpassed the goal of 3,000 observations. Between July 1-Aug. 31, you contributed a whopping 3,639 observations of wild turkey hens with or without poults. Thank you!

After DNR Division of Fish & Wildlife biologists removed duplicates and reports without exact locations, 2,203 brood observations are being factored into regional production estimates.

Because of your help, we can continue to track population trends and make important management decisions to foster healthy ecosystems in Indiana.

Why count turkeys?
Brood surveys provide useful estimates about annual production by wild turkey hens and the survival of poults (young turkeys) through the summer brood-rearing period. Summer brood survival is generally the primary factor influencing wild turkey population trends. Information on summer brood survival is essential for sound turkey management. Information gathered through the brood survey includes:

• Average brood sizes (hens + poults). For example, in the photo above there is one hen with seven poults, for a brood size of eight.
• Percentage of adult hens with poults.
• Production Index (PI) = total number of poults/total number of adult hens

What is a wild turkey brood?
A wild turkey brood is composed of at least one adult hen with young (poults). As the summer progresses, multiple broods may gather into what is termed a “gang” brood with several adult hens and multiple broods of poults of varied ages. During summer, adult gobblers (male turkeys) play no role in raising a brood and either form small male only “bachelor” flocks or are observed as a single gobbler.

Wild Bulletin, Indiana Department of Natural Resources (DNR) Fish and Wildlife: Join the fun this fall and hunt one of Indiana’s gorgeous grassland birds. Quail hunting in Indiana starts on Nov. 10 and requires a Game Bird Habitat Stamp and a general hunting license. These species are present in grasslands across the state, such as Goose Pond FWA and Glendale FWA. There are no equipment restrictions for quail, but we recommend a 12- or 20-gauge shotgun with 6 to 9 shot. Remember to wear your hunter orange!

Some DNR properties may have additional regulations for quail hunting. Check with the property you’re planning to hunt for more details.

General Characteristics:
Northern bobwhites are a ground-dwelling species that only rely on flight on rare occasions. They rely on cryptic plumage color combinations and contrasts that provide excellent camouflage. They are minimally sexually dimorphic, meaning males and females have different physical characteristics. In the case of the Northern bobwhite, males have a white throat and chin, along with a white stripe above the eye extending to the back of the head. Those same areas on a female, are buffy brown in color. Underparts are tawny and white, blending with chestnut and gray. Each breast feather sports a black chevron. Upper parts of the shoulders, back, and rump, are a mixture of warm brown, cream, and shades of black. In Indiana, adult Northern bobwhites weigh an average of 180 grams (~6.5 ounces) and are about 10 inches long from bill tip to tail.

To identify and learn more about this species, please visit DNR: Fish and Wildlife: Northern Bobwhite.

Seafood is more than just fish caught in the ocean. It includes a wide variety of product types, forms, flavors, and textures. One of the great things about using seafood is its versatility—it can be served as a main course or be used as an ingredient for appetizers, salads, and soups. Packed with important nutrients the human body needs to maintain good health, it is an excellent source of protein to include on your shopping list. Being informed about both the benefits and potential concerns with different types of seafood can help you decide which products to add to your cart or order at a restaurant.

This toolkit, designed specifically for nutrition and wellness professionals and educators, will provide you with information and resources to help you talk to your clients about the complex food category known as seafood. You will learn about the basics of seafood, nutrition benefits of including seafood as part of a healthy eating pattern, concerns about safety, tips for purchasing seafood, and ideas for cooking demonstrations. We’ve included simple and tasty recipes that you can use to introduce your clients to the many flavors of fish and shellfish, links to downloadable and printable handouts, and sample social media posts that you can use to inform and inspire.

This toolkit is geared toward extension staff who teach nutrition and wellness. It includes both printable and digital elements that can be shared with clients based on interest and need.

To receive the free download and recipe visit the Purdue Extension’s resource center: The Education Store – Seafood Basics: A Toolkit for Understanding Seafood, Nutrition, Safety and Preparation, and Sourcing.

Purdue Landscape Report: Temperatures are finally dropping and leaves are changing color. Autumn is progressing well in my opinion. Before you know it winter will be here, and some people will be wondering is there anything to be done to better protect the trees around you?  The answer is yes, and I applaud you for your initiative to continue caring for your trees. To give your trees the best chance to survive the winter and better thrive next year there is an assortment of activities available ranging from diy projects up to calling in an ISA certified arborist to help you out.

Mulching:
One simple task to better prepare your trees for winter is to add a new layer of mulch, which benefits your trees in multiple ways. Adding a 2-3 inch thick layer of mulch will better maintain moisture levels and buffer extreme temperature changes in the soil and will add some organic matter too. Mulching to the drip line will benefit the tree the most, but in the case of larger trees it’s not always feasible. Try for at least a 3-foot radius from the trunk and make sure to leave a 2 inch or so gap between the trunk and the mulch. Remember, no volcano mulching.

Fertilizing:
That mulch you just added will add some organic material to your soil as it slowly breaks down, but an autumn fertilization can benefit your trees too. Unlike trees in the forest that have a natural supply of nutrients from fallen leaves and twigs, trees around our homes are usually deprived as we rake and clean up our yards. Adding a slow-release fertilizer in the fall helps provide a nutrient boost over the winter, can promote root growth, and better prepare your tree for Spring.

Watering:
Water is still an essential part of your tree care plan, but as temperatures drop and trees begin to head into dormancy they don’t need as much water as is required in the hit summer months. If you have irrigation systems in your yard start to drop the frequency of watering. You can water up until the first freeze, but make sure soils are just a little damp and not soaked. Evergreens in particular will benefit from slow deep watering 1-2 times a week until the soil freezes. Winter winds and temperatures can desiccate the needles without an adequate supply of water.

Pruning:
Now is a good time to prune out any dead, damaged, or diseased limbs in your trees. If you have access to hand saws and pole saws or pruners, you can remove smaller branches or those closer to the ground. Make sure you are making proper pruning cuts though, and if there are large limbs, those at heights, or you are just unsure of how to make a good cut enlist the help of a professional arborist.

Trunk damage:
Sunscald or southwest damage occurs on young and/or thin barked trees in the winter. Wounds can occur between the south to southwest facing part of the trunk on sunny days in the winter as temperatures rise and suddenly drop. Over time these wounds can become quite large. Trees can also incur damage from deer during the rut. Bucks will scrape trees with their antlers, scraping off the bark and damaging the cambium. Both of these injuries can be reduced one younger trees by installing tree guards in the fall. Tree guards are plastic barriers you place around the main stem of the tree. I recommend using white corrugated drainage pipe that can be found at most home centers. You can make a cut lengthwise along the pipe for easy installation and make sure it has a large enough diameter to leave a space between it and the tree. Just remember to remove it come Spring.

Inspections:
Visual inspections can be done year-round, but this time of the year it might be easier to see changes in your tree as leaves are falling and the canopy becomes more visible. From the ground up to the canopy, some of the things you’re looking for include fungal growth around the base of the tree, any sort of damage on the main stem or branches, premature leaf drop or color change, and branches that are dead, cracked, diseased, or seem weak. Any concerns you find are also great information to share with an ISA Certified arborist which can be found using the Trees Are Good website.

Purdue Landscape Report: Many areas around the Midwest continue to creep towards an increasing drought situation.  Currently almost 80% of the Midwest is listed as being abnormally dry to exceptional drought.  Current soil moisture data indicates that most of the Midwest is very dry.  Going into the fall it’s very important to supply enough supplemental water (irrigation) to make up for the deficit prior to the landscape plants going dormant over the next six to eight weeks.

The fall is a very important time to limit stressors on landscape plants.  A stressed plant doesn’t produce as many secondary metabolites which aide in increased cold hardiness; so keeping your landscape plants irrigated during dry periods in late summer into fall is an important component of preparing plants for winter.

Remember some key steps concerning your landscape during extreme dry periods:

• Don’t wait until leaves begin dropping to start watering.
• Trees should receive the 5+5 rule.
  • 5 gallons, plus 5 gallons per caliper inch.

• Ideally watering should occur in the early morning to prevent foliar diseases.
• Mulching to 3” can conserve moisture and reduce temperature in the upper root zone.
• Watering during dry conditions will help prevent future insect, disease, and other stress issues going into the fall and the following year. In fact, plants going into the winter that are stressed due to water deficiency will reduce the cold hardiness and therefore will be more likely to suffer cold injury and/or death.
• If a plant isn’t receiving enough water, the amount of nutrient uptake will not be sufficient and will experience deficiency from nutrients the following year.

Illinois-Indiana Sea Grant Newsroom: Navigating the dos and don’ts of seafood consumption during pregnancy and breastfeeding can be quite challenging and even confusing at times. With a dozen or more seafood choices to navigate, making the right decision for you and your baby is not always easy. In the past, even medical professionals and dietitians offered conflicting advice, cautioning against seafood consumption during pregnancy.

However, things have changed significantly, thanks to the extensive efforts of experts like Charles Santerre, a former food toxicology professor at the Purdue University College of Health and Human Sciences.

Santerre, along with student researchers and a team of experts from across the United States, dedicated over a decade to unraveling the developmental benefits and risks associated with seafood consumption during pregnancy. Their research played a crucial role in establishing the foundation for seafood consumption standards that prioritize the health of babies and children.

Today, the Food and Drug Administration and the Environmental Protection Agency, along with university-created websites such as Fish for Your Health™, provide science-based seafood consumption advice that advocates for eating seafood rich in omega-3 fatty acids and low in mercury and PCBs twice per week.

Purdue Landscape Report: When I was a kid, if you’d asked me what my favorite season was it would always immediately be summer. No school, time for playing outdoors, swimming, hiking, and late nights playing flashlight tag. Now, if I ranked the seasons from worst to best, they’d be Summer in last, followed by Winter (yes, I choose winter over summer), and a tie between Spring and Fall.  With the best temperatures, a mix of sun and rain/snow, and an explosion of colors from new blooms in the spring to the reds, yellows, and oranges of leaves before they drop in the fall, Spring and Fall are by far my favorite times of the year.  Well, we are nearly to the autumnal equinox with temperatures beginning to drop and the onset of some fall showers as I write this article. With Fall on the doorstep, I’ve received a repeated question recently, “Is it ok to plant a tree in the Fall?”

The short answer to this question is, “Yes!” If you want to add some new tree canopy to your yard, then pick your spot, choose the appropriate species, call #811 before you dig, and get that shovel out. Fall has some excellent reasons to plant trees, two of which I’ve already mentioned, cooler temps and autumn rains. While Autumn tends to be the driest time of the growing season, evapotranspiration rates are generally lower than during the summer season. These conditions reduce heat and water stress on trees (but are not an excuse to not mulch and water your new tree). Another good reason to plant in the fall as opposed to Spring is that instead of amping up for growing, trees are powering down and putting resources into root growth and storage. This means better establishment for the root system and a head start on protection for next year’s summer heat and drought.

There are some points to take into consideration, though. Again, make sure to properly water and mulch your new trees. They need an average of 5 gallons a week per inch of stem diameter if weekly rain isn’t providing around 1” of water. Be aware of when the first freeze is expected. You want to make sure your new trees have at least 6 weeks in the ground before the first freeze/frost and can stop watering after the first freeze. Also, for tree selection/protection, avoid broad leafed evergreen trees as they can be damaged by cold desiccation and wrap the trunks of your new trees to protect them from sunscald and animal damage like rubbing from bucks during the rut.

If you keep these points in mind and continue caring for your tree for the next 2-5 years you should have a successful planting. If you have any questions feel free to contact me at bmccalli@purdue.edu or you can find an ISA Certified Arborist at the following link Find an Arborist.
