Agricultural & Natural Resources (ANR) Newsletter: On May 5, Natural Resources professionals gathered at the Davis Purdue Agricultural Center (DPAC) in Farmland, Indiana, for a forestry and wildlife management training led by Purdue Forestry and Natural Resources’ Brian MacGowan, wildlife extension specialist and extension coordinator; Don Carlson, forester; Jarred Brooke, wildlife extension specialist; and Jessica Outcalt, natural resources training specialist. The program combined classroom updates with field-based learning focused on active land stewardship, habitat management and conservation planning.

During the field tour of DPAC and Herrmann Properties, participants explored topics including native warm-season grass management using prescribed fire, Sericea lespedeza control in native grass plantings, prairie restoration, young forest management, and oak forest management for multiple objectives. Don Carlson discussed the history and management goals of DPAC, emphasizing how tree spacing, mowing and the use of crop and nurse trees influence tree establishment and growth. Jarred Brooke highlighted challenges such as rabbit damage to young trees and invasive species management. Participants learned key wildlife habitat principles, including a practical guideline for quail habitat: If a baseball tossed into the grass rolls, the habitat structure is suitable for quail; if it does not roll, the vegetation is too dense. The day concluded with updates on the NR Training Hub, prescribed fire and evaluation efforts.

If you’re interested in bringing a program like this to your area, we’d love to hear from you, submit a request at fnrextension@purdue.edu.

Most of us have probably heard or seen a lot about pollinators in the media recently. The reason why is that pollinators are really, really important. We simply can’t live without them. Researchers estimate that one out of every three bites of food we eat is made possible by pollinators. More than 100 food crops in the U.S. depend on pollinators, including almost all fruit and grain crops.

There are many different types of pollinators including native bees, butterflies and moths, beetles, flies, wasps, and of course hummingbirds. But perhaps one of the more interesting pollinators is the Monarch. Millions of Monarchs congregate in a relative small area in Mexico each winter. In March they start their journey north which has occurred over several generations. Unfortunately, the number of Monarchs counted in overwintering colonies has declined over the past 25 years.

In response, many states including Indiana have developed a state Monarch Conservation Plan. With input from many stakeholders over several years, the Indiana Monarch Conservation Plan was released in December 2020. One goal of the plan was to create an online resource that would act as a clearinghouse for Indiana monarch and pollinator conservation data, research, best management practices (BMPs), and events. I invite you to visit the Indiana Monarch and Pollinator Conservation Hub at indianawildlife.org/monarchs.

You might be asking yourself, ‘Why is a wildlife specialist writing about pollinators?’ It turns out that quality habitat for wildlife is often quality habitat for pollinators. The diversity of wildflowers and structure that native grasslands, trees and shrubs benefit them all. Trees such as eastern redbud and Ohio buckeye provide early nectar sources. Native grasslands that have a diverse mixture of wildflowers provide food, bare ground, and structure desirable for a wide variety of pollinators.

With storm season just around the corner, one topic of concern on many minds is damage to and from trees. Depending on the intensity of the storms and the condition of the trees, damage from high winds, heavy rainfall, and lightning can be quite severe. Cracked or broken branches, stem failure, and root failure are some of the main concerns, but also the risk and liability of damage to people and property.

If your tree is damaged, there are some steps to deal with the situation. First and foremost, consider the safety of yourself and others around you. Inspect the tree from a distance first looking for the following:

• Heaving of the ground indicating potential root failure
• Damage to limbs and/or the trunk of the tree
• Hanging branches can fall to the ground resulting in injury or death
• Be aware of utility and power lines. Trees can become charged by coming in contact with live wires. All utility lines should be considered energized and dangerous.

If you find your trees damaged from a storm hiring an International Society of Arboriculture (ISA) Certified Arborist to perform a risk assessment will help guide your decision of how to manage your tree. To find an arborist near you and verify credentials use the link at Find an Arborist, Trees are Good, International Society of Arboriculture (ISA). For more information, you can also view Trees and Storms: Understanding Damage, Risk and Recovery, an informational Got Nature? Blog article from Purdue Extension.

You know Spring is around the corner when the days get longer and the temperatures rise. While the weather has pleasantly been warm this year so far, perhaps my favorite harbinger of Spring is the annual arrival of the American Woodcock, also known as the Timberdoodle. Their unique “peents” and the spectacular aerial flights of males looking to attract mates can be very entertaining.

Woodcock are migratory and spend their winters in the southern U.S. They arrive in Indiana in the early spring. Male woodcock typically set up their singing grounds in open fields and forest openings and recently logged areas. However, they can often be seen in urban areas including parks and even residential communities. The best time to observe them is at dusk. Woodcock will spend time on the ground “peenting” for a while, then fly high into the air to perform their “dance” only to return to the ground where they will repeat the process. This will go on until it gets dark. You can sometimes hear them peent in the morning before sunrise.

If you’re outside around dusk in early spring, keep an ear out — you just might hear the peent of a timberdoodle nearby.

Hummingbirds are a popular attraction in any backyard and we receive questions on when they will be coming to Indiana and how to attract them to your backyard. Our Purdue professor emeritus of wildlife ecology Barny Dunning in this interview for CBS4 Indianapolis titled “How to attract hummingbirds during peak migration,” shares how planting a variety of plants that bloom will help draw them in along with a simple hummingbird mixture.

The ruby-throated hummingbird is the only species of hummingbird that nests in the Hoosier state. These colorful visitors are migratory and arrive from their wintering grounds around mid-April.

Dr. Brian MacGowan has a publication titled Attracting Hummingbirds to Your Yard that is a great resource to share along with this video showing how to prepare your hummingbird feeders and how to find out when they will be migrating to your area. Hummingbird Central also tracks spring and fall migrations. Anyone can submit sightings on their website and view up-to-date sightings.

MyDNR, Indiana’s Outdoor Newsletter: While temperatures were frigid, conditions were perfect for DNR mammalogists to conduct surveys for rare and endangered bats. About half of the bat species found in Indiana avoid the cold by seeking out climate-controlled caves where they can hibernate.

During this time, biologists count bats to get a snapshot of roughly how many of each species are present. Conducting surveys regularly provides a better understanding of population trends over time and conducting them at the same time every other year helps to minimize disturbance. The surveys primarily target the Indiana bat, but also include counts for the gray bat, little brown bat, tricolored bat and big brown bat.

Donations to the Indiana Nongame Wildlife Fund help the DNR purchase equipment needed for surveys. One critical tool is digital cameras which enable biologists to spend less time in caves disturbing the bats and more time in the office viewing photos to obtain a more accurate count.

While the data is still being tallied for the 2026 winter bat count, the impression DNR mammalogists have from this winter’s surveys is that multiple bat species continue to show signs of population growth.

Want to help bats? You can give them the best chance to thrive by growing native plants, installing bat houses, protecting forested habitat and minimize disturbance to bats.

Indiana joined 22 other states in 2025 when it launched its state-level Certified Prescribed Burn Manager (CPBM) Program. This program resulted from HB-1557, which went into effect on July 1, 2025. For more information about the new prescribed fire law in Indiana and what it means for burners, check out the Indiana Prescribed Burn Law Factsheet.

This article will walk through the steps to complete all stages of the program. The Indiana DNR CPBM Policy can be viewed by visiting the Indiana Prescribed Fire Council website.

The CPBM program consists of three parts:

• Online Training
• In-Person Training
• Prescribed Burn Experience

Indiana CPBM Requirements At-a-glance

1. Online Training
   1. S-130
   2. S-190
   3. L-180
   4. IS-100
2. In-Person Training
   1. S-130 Field Day (no pack test requirement)
   2. Indiana DNR Prescribed Fire for Managers
3. Burn Experience (Minimum of 5 total burns for experience)
   1. Participate in 5 prescribed fires
   2. At least 3 in woodland at least 1 in grassland
   3. Ben an Apprentice Burn Manager for 2 burns
   4. 1 woodland and 1 grassland burn
4. Paperwork and Documentation
   1. IN CPBM Application
   2. IN CPBM Experience Log
   3. IN CPBM Task Book
   4. Burn Plans for Apprentice Burns

Online Training Requirements

The online training required for the CPBM program includes many of the same courses as are necessary for Basic Wildland Firefighting.

• S-130 Firefighter Training
• S-190 Introduction to Wildland Fire Behavior
• L-180 Human Factors on the Fireline I
• S-100 Introduction to the Incident Command System

These are self-paced, free online courses available through FEMA, the National Fire Academy (NFA), and the Wildland Fire Learning Portal.

• FEMA – IS-100
• National Fire Academy Registration Page – S-130, S-190, L-180
• Wildland Fire Learning Portal – S-130, S-190, L-180

*Before taking any courses through FEMA or registering for the NFA, you need to obtain a FEMA SID#. You can do that at FEMA: Student Identification System.

In-Person Training Requirements

The two requirements for in-person training are:

• S-130 Field Day (1-day; no pack test required)
• Indiana DNR Prescribed Fire for Managers (2-day)

How to complete the in-person training?
In-person S-130 Field Days and Indiana DNR Prescribed Fire for Managers courses are offered 1-2 times per year, often offered in the spring (Feb-Mar) and in December.

*To take the S-130 Field Day, you need to complete the required online training before the field day. To take the Prescribed Fire for Managers Course, you need to take the S-130 Field Day.

You can find information about upcoming trainings by visiting the Indiana Prescribed Fire Council (INPFC) website and the Indiana DNR Fire Headquarters Training Portal.

Prescribed Burn Experience

To be an Indiana CPBM, you need the following prescribed fire experience:

• Participate in 5 prescribed fires across the 2 major fuel model groups in Indiana (grass and hardwood timber litter)
  • At least 3 of the burns shall be in the hardwood timber litter fuel model
• Serve as an Apprentice Burn Manager on 2 of the 5 prescribed burns – 1 from each of the two fuel model groups (grass and timber litter)

Serving as an “Apprentice Burn Manager” means you need to lead burns under the guidance of an existing CPBM, RxB1, or RxB2 (RxB1 & RxB2 are Burn Boss qualifications through the National Wildfire Coordinating Group) and complete a Certified Prescribed Burn Manager Task Book related to preparing for and managing a prescribed burn.

How do I receive prescribed fire experience?

To get experience as a crew member on prescribed fires, here are a few steps:

• Meet Common Training Requirements: Many organizations (but not all) require burn crews to have basic wildland fire training courses, many of which are needed for the CPBM program. Having these trainings will open the door for more opportunities.
  • Basic Wildland Firefighter (FFT2) Requirements (bolded are required for CPBM)
    • S-130 (Online and Field Day)
    • S-190
    • L-180
    • IS-100
    • IS-700B
    • Arduous Work Capacity Test (Pack Test)
• Attend a Learn-N-Burn: these half- or full-day events can help you get your feet wet with prescribed fire and are offered by groups like the Indiana DNR Division of Fish and Wildlife and Purdue Extension. Generally, prior experience or training is not required for these events.
  • Upcoming Learn-N-Burns can be found under Events on the INPFC events website.
• Find Volunteer Opportunities: Many organizations accept volunteers for prescribed fire, but may require Basic Wildland Firefighter Training (see above).
  • Volunteer on burns with The Nature Conservancy
    • To be a TNC fire volunteer, you need to be a FFT2 or complete the Prescribed Fire Crew Member (RxCM) standard, which is similar to FFT2 standards but does not require IS-700 and requires a moderate pack test. View the TNC Fire Manual for more information.
  • To learn more about helping TNC on prescribed burns, contact Stuart Orr, Indiana Fire Program Manager at sorr@tnc.org.
• Volunteer with your Local Land Trust
  • Indiana is home to over 20 land trusts, many of which utilize prescribed fire.
  • Each land trust may have different requirements to volunteer for prescribed fire.
  • Visit the Discover Your Land Trust page on the Indiana Land Protection Alliance website to find a land trust in your area.
• Find landowners in your area who are using prescribed fire and volunteer to help
  • Several landowners across Indiana use prescribed fire and may be seeking help.
    • You may be able to find landowners who burn through existing conservation networks, such as local NGOs (NWTF, NDA, PF, or QF Chapters) or landowner groups such as the Indiana Forest and Woodland Owners Association.
  • Join or start a Prescribed Burn Association, which is a collection of landowners who help each other burn by pooling resources, equipment, knowledge, and crew through a “Neighbor Helping Neighbor” model.

How do I receive apprentice burn manager fire experience?

The first step in finding opportunities is building relationships with current prescribed fire practitioners. By volunteering as a crew member, you start to learn about prescribed fire and build relationships with existing burn managers. This may lead to opportunities to apprentice in the future.

The Indiana Prescribed Fire Council is piloting a Prescribed Fire Opportunity Sharing Network to help connect those seeking burn experience with experienced burners. You can use the links below to sign up for this network as either a Mentor (have experience) or Mentee/Apprentice (need experience). Register on the Mentor sign-up or the Mentee sign-up.

Poison hemlock is native to Europe. It is a biennial plant, meaning that it has a two-year lifespan. Last summer, it went through vegetative growth and largely stayed out of sight as a basal rosette. This summer, a long stem (up to 3 to 10 feet tall) will bolt and produce small white clusters of flowers. Poison hemlock is a member of the parsley family and can sometimes be confused with wild carrot. However, its distinguishing feature is its hairless hollow stalks with purple blotches.

The biggest risk with poison hemlock is ingestion. Lethal doses are fairly small, so it is important for animal owners or parents of young children to identify it in their area and remove it if possible. The toxins can also be absorbed through the skin and lungs, so be sure to wear gloves and a mask when handling these plants.

Symptoms of hemlock poisoning include dilation of the pupils, weakening or slowing pulse, blue coloration around the mouth and eventually paralysis of the central nervous system and muscles leading to death. Quick treatment can reverse the effects, so act quickly.

It is considered highly invasive and is listed on both Indiana’s noxious weed list and the terrestrial invasive plant rule list, Indiana General Assembly IC 14-24-12, IC 15-15, IC 15-16-7 to 10, Indiana Department of Natural Resources, Terrestrial Invasive Species – Plants. Thus, its occurrence may have legal implications for landowners. Some Indiana counties aggressively monitor and spray poison hemlock, particularly along county roads. It primarily invades disturbed and early succession sites such as roadsides, stream and ditch banks, vacant lots, and field borders. However, it can spread into pastures, hay fields, and other grassland habitats.

Its sap contains alkaloid toxins which are highly toxic to humans and animals. Although humans would not normally purposely or accidentally ingest poison hemlock (Socrates was a notable exception), care should be taken when mowing or cutting to avoid dermal and respiratory inhalation exposure. Livestock farmers should control poison hemlock in pastures, feed lots and holding pens and ensure it is not baled in hay.

Poison hemlock spreads via seed, so effective management must prevent new seed production, prevent spread of existing seed, and exhaust the existing seed supply in the soil seed bank.

Poison hemlock seed is often inadvertently spread by mowing, road maintenance or agricultural equipment. Mow infested areas along roadsides, ditch banks and field edges before seed develops. A single mowing may delay but  not stop poison hemlock from growing another shoot and ultimately flowering and producing seed. Multiple mowings are likely required to prevent new seed production.

Herbicide control should focus on the first-year basal rosette. Herbicide control can still be achieved in the early stages of flower stem development. However, as the flower stem grows so grows the amount of herbicide required to provide full coverage and thus full control.  A 2% solution of glyphosate (41% active ingredient) in water with a non-ionic surfactant will provide good control of poison hemlock basal rosettes. If the poison hemlock is growing among desirable grasses, broadleaf-specific herbicides such as triclopyr and 2,4-D are also very effective on poison hemlock and will not harm the grasses. AS always, read the pesticide label for proper, safe handling and use.

For more information see Purdue Cooperative Extension Invasive Plant Fact Sheet Series FNR-437-W, Poison Hemlock.  For further guidance on poison hemlock control, contact your county Purdue Cooperative Extension office.
