Indiana Forestry & Woodland Owners Association (IFWOA) News: If you live in Indiana and own more than ten acres of woodlands, then you may want to enroll in the Classified Forest and Wildlands Program offered through the Indiana Department of Natural Resources (DNR), Division of Forestry. This program encourages timber production, watershed protection, and wildlife habitat management on private lands in Indiana. Program landowners receive a property tax reduction in return for following a professionally written management plan. In addition to the tax incentive, landowners receive free technical assistance from DNR foresters and wildlife biologists, priority for cost-share to offset the cost of doing management, and the ability to “green” certify their forests. The minimum requirement for program enrollment is 10 acres of forest, wetland, shrubland, and/or grassland.
“Once enrolled in our program, you get a reduced property tax assessment,” says Gretchen Herbaugh, District Forester with Indiana DNR serving southwestern Indiana.
“Property can be anything from forest ground to native grasses to pollinator habitats to wildlife food plots—we span a large range of habitat types and management styles,” Herbaugh says.

Wild Bulletin, IN DNR, Division of Fish & Wildlife: Epizootic hemorrhagic disease (EHD) is a naturally occurring viral disease commonly seen in the Indiana deer herd. Each year, typically in late summer, Indiana DNR receives reports of deer displaying signs of EHD throughout the state.
This year, DNR confirmed a significant EHD outbreak that began in the northern region of the Hoosier State. In some years, EHD can affect a larger-than-normal portion of the deer and becomes widespread across a county. In those instances, DNR lowers the County Bonus Antlerless Quotas (CBAQs) in the impacted counties to offset the effect of the counties’ EHD outbreak on the deer herd in that region.
EHD is transmitted by biting midges, also known as sand gnats or “no-see-ums.” Deer infected with EHD may display unusual behaviors such as lethargy, excessive salivation, or disorientation. EHD also causes fever in deer, which can cause deer to seek water. As a result, many deer that die from EHD are found in or near open water sources like ponds and rivers. Anyone who finds a deer showing signs of EHD or dead in water is asked to report it at on.IN.gov/sickwildlife.
County bonus antlerless quotas reduced in three counties for 2024-25
Due to the number of reported deer mortalities and extent of EHD in the region, DNR has lowered the County Bonus Antlerless Quotas (CBAQs) in Wabash, Porter, and Allen counties from two bonus antlerless deer to one to help offset the effects of EHD on the deer herd in that region. During the winter, DNR biologists will fully evaluate the effects of EHD and will propose changes to bag limits as required. Hunters can stay informed about CBAQ changes at on.IN.gov/EHD-quotas.
To find out more view the Indiana Department of Natural Resources EHD Antlerless Bonus Quota Reductions.

Purdue Landscape Report: We have received a few elm tree samples this year with a disease we do not often see, but which is relatively common: black spot of elm. This disease, also called elm anthracnose, is caused by the fungus Stegophora ulmea and can affect most species of elm with American elm varieties being more susceptible.

Figure 1. Elm foliage with chlorotic spotting and black fungal structures caused by Stegophora ulmea.
The fungus becomes active in the spring at temperatures of 45 deg F or above. It can release spores that will infect newly unfolding leaves leading to chlorotic leaf spots or blotches on the upper leaf surface. Black fungal fruiting bodies will develop within the affected tissue, making it seem like the leaves have been dotted with tar. These fungal structures are raised and will give the leaf a bumpy texture. As more spots develop and coalesce, they will create white areas of dead tissue that can eventually turn brown.
The black fungal stromata can produce asexual spores (conidia) which can cause new infections during the growing season. Conidia are produced in a mucilage which becomes loose in humid conditions and can be spread by water splash (rain or irrigation). While leaf infections are the most commonly observed symptom, Stegophora can also infect leaf petioles and twigs. Premature leaf drop due to severe leaf spotting can occur, but significant defoliation may also develop when petioles are infected. Stem infections can lead to shoot blighting and small limb dieback.
Black spot is generally worse when the weather is cool and moist over an extended period of time. The fungus can reinfect the tree throughout the season during rainy. When the summer turns hot and dry, disease development will slow down and trees with twig blighting may show some recovery by pushing out new growth from dormant buds below affected shoots. Please note that twig blighting may look similar to flagging branches associated with Dutch elm disease (DED), so we recommend pruning off the branch and looking for internal vascular streaking to rule out DED.
Fungicides are not normally recommended to manage this disease for mature trees in landscapes since it is impractical to get full coverage of the foliage and damage is not usually severe. However, preventative applications may be warranted in nursery settings when the disease is severe to protect new growth and slow down disease spread until drier weather occurs, especially where overhead irrigation is used. Raking up leaf litter and pruning out infected stems will remove inoculum for the following season and help prevent existing infections from spreading.

The USDA Natural Resources Conservation Service, shares news article announcing the December 6, 2024 deadline for the Southern Indiana Sentinel Landscape Regional Conservation Partnership Program (RCPP).
Funding Available to Landowners Through the Southern Indiana Sentinel Landscape Regional Conservation Partnership Program
October 8. 2024
Damarys Mortenson, State Conservationist for USDA’s Natural Resources Conservation Service (NRCS) in Indiana announced today the deadline to apply for funding through the Southern Indiana Sentinel Landscape Regional Conservation Partnership Program (RCPP) is Dec. 6.
RCPP is a partner-led program, with NRCS directing technical and financial assistance to priorities identified by partners. Led by the Conservation Law Center, and the Southern Indiana Sentinel Landscape Partnership (SISL), this RCPP is part of a larger initiative to address pressing environmental concerns in the region.
“SISL is a great example of public, private and non-profit organizations working together to solve local concerns,” said Mortenson. “The partners are building on years of successful collaborations focused on natural resource protection, making a greater environmental impact within the focus area.”
Beginning about 20 miles south of Indianapolis, SISL comprises a unique patchwork of land uses. It is anchored by four critical Department of Defense installations and ranges and also contains state parks, state forests, state fish and wildlife areas, state-dedicated nature preserves, the Hoosier National Forest, and National Wildlife Refuges.
These natural and working lands provide an opportunity for partners and stakeholders to sustainably manage forests, build soil health and resiliency on agricultural lands, improve ecosystem health and maintain areas compatible with the military mission. SISL’s overarching goals are to preserve and protect military missions, support sustainable farming and forestry, restore and sustain ecosystems, ensure thriving human communities, and improve climate resiliency. Combined, these efforts have the potential to mitigate the effects of existing encroachment threats or avoid them altogether.
“Protecting Indiana’s oak-hickory ecosystems is essential not just for preserving our natural heritage, but also for safeguarding biodiversity, water quality, soil health and wildlife habitats,” said Mortenson. “The Southern Indiana Sentinel Landscape plays a major role in helping to maintain ecological balance, support countless species and provide clean air and water for southern Indiana communities.”

For more information regarding the Southern Indiana Sentinel Landscape view The Sentinel Landscapes Partnership website, Southern Indiana Sentinel Landscape.
The Sentinel Landscapes Partnership is a coalition of federal agencies, state and local governments, and non-governmental organizations that work with willing landowners and land managers to advance sustainable land use practices around military installations and ranges. Founded in 2013, the partnership aligns the objectives of the U.S. Department of Agriculture, Department of Defense, Department of the Interior, and Federal Emergency Management Agency to strengthen military readiness, conserve natural resources, bolster agricultural and forestry economies, increase public access to outdoor recreation, and enhance resilience to climate change.

Purdue Landscape Report: The elm zigzag sawfly (EZS), Aproceros leucopoda, is a non-native insect recently detected in several midwestern states. Originally from eastern Asia, this insect is rarely considered a problem in its native range, having several natural enemies and environmental factors able to keep it in check.
However, when in new landscapes, aspects of this insect’s life cycle enhance its ability to spread across new habitats and do significant damage to its host plant, the elm tree. EZS was first detected outside of its native range in Europe in 2003. Then, in 2020, it was found in North America for the first time in Quebec. It has since been detected in several states in the US, spreading first through the Northeast before entering the Midwest. It has not yet been detected in Indiana, but has been in the surrounding area.
Elm zigzag sawfly is a member of the insect order Hymenoptera, which includes bees, ants, and wasps. More specifically, sawflies belong to a suborder known as Symphyta, whose members are noted for a broad-waisted appearance and a saw-shaped ovipositor. Sawflies are a fairly common group of insects, though observers will often overlook them or confuse them for other insects. Adult EZS are generally small, darkly-colored insects that are easy to write off as ‘just another black bug’ you see around the garden or yard (Fig. 1).

Figure 2. Elm zigzag sawfly larva feeding, Gyorgy Csoka, Hungary Forest Research Institute, Bugwood.org
They resemble wasps, but possess a broad waist with no narrowing of space between the thorax and abdomen, and they lack a stinger. EZS larvae closely resemble caterpillars in both form and feeding habits, with pale green coloration, a black stripe that runs down the length of the body, and dark T-shaped markings on the legs (Fig. 2). The larvae, like moth and butterfly caterpillars, will also possess six pairs of fleshy prolegs that are lost upon reaching maturity. While the larvae bear chewing mouthparts to consume the leaf material of many kinds of plants, the adults are nectar and pollen-feeding. It should be noted that EZS larvae chew zigzag patterns into elm leaves, thus the common name of the insect. Like bees and wasps, sawflies also possess wings, but are typically lazy fliers, choosing to fly only during warm, sunnier periods of the day.
