How to Read the Signs
Most trees don't fail without warning. The trouble is, the warning signs can be easy to miss or dismiss, especially if you're not sure what you're looking at. A crack in the trunk, a lean that seems slightly off, a few dead branches after a rough winter — these things can look minor until they aren't.
Brookings gets its share of heavy weather. Ice storms, strong spring winds, and wet snow can stress trees that were already struggling, sometimes pushing a borderline situation into a genuine hazard. Knowing what to look for before something goes wrong gives you more options and more time to respond thoughtfully.
This page walks through the signs that point toward emergency tree removal, what makes a situation urgent versus something you can evaluate over a few days, and when it makes sense to call a professional for an on-site look. The goal is simple: help you make a clear-headed decision about the trees on your property.
What to Watch For
Some tree problems can wait a few weeks for a scheduled appointment. Others really can't. Here are the signs that put a tree in the "call now" category:
- Severe leaning after a storm. A tree that has suddenly shifted its angle, especially if the soil around the base is heaving or cracking, may have a compromised root system. That kind of lean is different from a tree that has always grown at a slight angle.
- Large hanging or partially broken limbs. Branches that are cracked but still attached are sometimes called "widow makers" in the trade, and for good reason. They can drop without warning, particularly when wind picks up again after a storm.
- Visible root damage or exposed roots. Construction work, erosion, or ground disturbance can sever or crush the roots that keep a tree anchored. A tree with significant root loss is far less stable than it looks from above.
- Hollow or extensively decayed trunk. Soft spots, visible cavities, or sections of bark that sound hollow when tapped can signal that the internal structure holding the tree upright has been compromised.
- Cracks or splits in the main trunk. Deep vertical cracks or splits where two major limbs meet are structural red flags. These often indicate the tree is already under stress it may not be able to handle.
- Tree making contact with power lines. Any situation where branches or the trunk are touching or growing into utility lines needs professional attention quickly.
- Heavy fungal growth at the base. Mushrooms or shelf fungi growing from the roots or lower trunk often point to internal decay that isn't visible from the outside.
How Urgent Is It?
Not every tree situation is a true emergency, even when it feels like one. Taking a moment to assess what you're dealing with can help you make a clearer call about how fast to act.
Start with the most obvious hazards. A tree or large limb resting on your roof, a vehicle, or a utility line needs attention right away. Don't go near downed lines yourself. Contact your utility provider first, then a tree service. Those situations genuinely can't wait.
A tree that has fallen into your yard but isn't touching any structure is a different matter. It's still a job that needs handling, but you usually have a little more time to get multiple opinions and plan the work properly.
The harder calls involve trees that are still standing but look compromised. A trunk with a fresh split, a tree leaning noticeably after a storm, or one with large hanging limbs overhead all deserve a prompt professional assessment. The risk isn't always obvious from the ground.
A few questions worth asking yourself:
- Is the tree or any part of it touching or directly threatening a structure?
- Is anyone at risk if it moves or falls further?
- Has the root system shifted or heaved out of the ground?
If the answer to any of those is yes, treat it as urgent. When you're genuinely unsure, a qualified arborist can give you an honest on-site read of the situation.
The Value of an Inspection
Not every tree situation calls for an emergency call at midnight. Sometimes a tree looks bad after a storm but is actually stable, and other times a tree that seems fine is carrying serious structural risk. That uncertainty is exactly where a professional assessment earns its value.
An ISA Certified Arborist can look at the full picture: root health, trunk condition, canopy structure, and how close the tree sits to your home, vehicle, or utility lines. They're trained to spot problems that aren't obvious to the untrained eye, like internal decay, root failure, or a compromised branch union that could fail under the next heavy wind or ice load.
Many certified arborists will provide a written assessment after their visit. That documentation is useful if you're weighing removal against other options, or if you need to share findings with your insurance company.
Hiring someone with ISA Certified Arborist credentials gives you a baseline of confidence that the evaluation is grounded in recognized professional standards, not just a sales pitch for a job. If you're genuinely unsure whether a tree needs to come down now or can wait, that conversation with a qualified arborist is a reasonable first step.
Common Questions
What signs after a South Dakota storm mean a tree needs emergency removal?
After a severe thunderstorm or straight-line wind event, look for these red flags: large limbs hanging by a thread of bark, the trunk visibly cracked or split near the base, or the root plate starting to lift on one side. A tree leaning at a new angle after a storm is not stable. Any of these conditions near a home, driveway, or utility area warrant a call to a qualified tree service professional rather than a wait-and-see approach.

How does Eastern South Dakota's freeze-thaw cycle affect tree stability?
The repeated freezing and thawing that Eastern South Dakota sees through late winter and early spring can quietly damage a tree's root system and trunk tissue. Soil that heaves and settles repeatedly may loosen the root anchorage of older or already-stressed trees. If you notice a tree leaning slightly more each spring, or soil cracking around the base, those are worth having a professional evaluate before the next wind event creates an urgent situation.
—
Can a tree look healthy on the outside but still be an emergency risk?
Yes, and this is a common reason homeowners are caught off guard. Internal decay from fungal rot does not always show on the bark. Visible clues include mushrooms or conks growing at the base, soft or hollow-sounding wood when knocked, and bark that peels away in large sections. A tree with significant internal decay near a structure or high-traffic area may need prompt attention even if it still has full leaf cover.

Does emerald ash borer damage ever create an emergency removal situation in this area?
It can. Ash trees weakened by emerald ash borer infestation become structurally compromised over time, making them more prone to sudden branch failure or whole-tree collapse, particularly during ice storms or high winds. Eastern South Dakota has seen emerald ash borer spread into the region, and ash trees that have lost significant canopy or show heavy dieback in the upper crown should be assessed by an arborist. A heavily infested tree near a building or road may reach a point where removal becomes urgent rather than optional.
When in Doubt
Some situations give you time to think. A tree that's leaning slightly, or one you're keeping an eye on after a storm, might be fine to monitor for a day or two. But if a tree has already fallen on a structure, a large limb is hanging over a place people use, or you can see the root plate lifting out of the ground, that's not a situation to sit on. Trust what you're seeing. A qualified tree service professional can assess the situation quickly and tell you what needs to happen and when. Getting an on-site evaluation costs you very little, and it gives you a clear answer instead of a lingering worry.
