The Wisconsin Department of Natural Resources (DNR) cautions hunters to avoid placing deer stands in or near ash trees this deer season as they start scouting properties.
Most ash trees in the southern half of Wisconsin, Door County and the Mississippi River counties are dead or dying from emerald ash borer (EAB) infestation. Although EAB is not as widespread in other parts of the state, the invasive insect continues to be found at additional locations throughout the state and unreported infestations are also likely present.
Tree stand accidents are the leading cause of serious injury to deer hunters. Research shows one in four bowhunters have experienced a fall or near-fall from an elevated stand.
It is important to place and maintain tree stands carefully, as trees infested with EAB may unexpectedly snap or drop large branches. Hunters should also be cautious around ash trees when on the ground, especially in windy conditions, as infested trees are susceptible to branch and stem breakage.
“Dead and dying ash trees are structurally weaker than healthy trees, so they are not safe places to put deer stands,” said Bill McNee, DNR Forest Health Specialist. “In many cases, it can be hard to tell if a tree has been infested by EAB, so hunters should place deer stands in other types of trees instead.”
Basic Rules Of Treestand Safety
No matter the type of treestand, follow these basic safety rules:
- Always wear a full-body harness also known as a fall-arrest system. Connect to your tether line and keep your tether line short. The tether is designed to keep you in the seat, not to catch you after you fall.
- Always have three points of contact while climbing into and out of the treestand, including two hands and one foot or two feet and one hand at all times.
- Always use a haul line to raise and lower your unloaded firearm or bow into and out of the stand. You can also use the haul for other things like a heavy backpack.
- Use a lifeline when climbing up and down, this keeps you connected from the time you leave the ground to the time you get back down.

How To Identify Ash Trees
Ash trees can be identified using two key features: opposite branching patterns where two branches come off the main stem directly across from each other and compound leaves with 5-11 leaflets.
More information on ash trees and how to identify them is available on the UW-Madison’s Department of Entomology EAB in Wisconsin webpage.
Avoid Spreading Forest Pests And Diseases
When traveling for hunting season, obtain firewood close to where it will be burned to reduce the chance of spreading tree-killing insects and diseases such as EAB, spongy moth* (formerly known as gypsy moth) and oak wilt.
Dry firewood with loose bark has the lowest risk of spreading harmful insects or diseases. Purchasing certified firewood is another option, as it is widely available and is seasoned or treated to eliminate pests and diseases. Bundles of certified firewood have a printed label showing certification.
More information about EAB, signs and symptoms of infestation and where this pest has been found is available on the DNR website.
*A new common name for Lymantria dispar, spongy moth, replaced the prior name of this insect, gypsy moth, in 2022. This change was necessary because the word ‘gypsy’ is an ethnic slur and the former common name equated people with insects. For more information, visit the Entomological Society of America website.
