How to Read the Signs
Most trees don't fail without warning. The trouble is, the warning signs can be easy to miss or brush off, especially when a tree has been standing in your yard for years and seems perfectly fine. A slight lean, a few dead branches, some bark that looks a little off — these things can feel minor until a storm rolls through and suddenly they're not.
For property owners in Brandon and the surrounding area, knowing what to look for before a situation becomes urgent makes a real difference. South Dakota weather can be hard on trees. Heavy snow, ice, and strong winds put stress on branches and root systems that may already be compromised. A tree that looks stable in calm conditions can become a serious problem quickly when the weather turns.
This page walks through the signs that point toward a potential emergency, so you can make a more informed call about when to act and when to reach out to a qualified tree professional for an evaluation.
Symptoms That Suggest a Problem
- A sudden or noticeable lean. If a tree has started leaning at a new angle, especially after a storm or heavy rain, that's worth taking seriously. A gradual lean over years is different from one that appeared recently.
- Large dead branches in the upper canopy. Dead wood doesn't always fall on a calm day. Branches that are bare while the rest of the tree leafs out, or ones that have lost their bark and look brittle, can drop without much warning.
- Cracks or splits in the trunk. Deep vertical cracks, or spots where the bark has separated and pulled away from the wood underneath, suggest structural weakness. A tree with a split trunk near the base is particularly concerning.
- Roots that are heaving or visibly damaged. If the ground around the base of the tree is lifting, or if you can see roots that have been cut, rotted, or exposed, the tree may not have the anchor it needs to stay upright.
- Fungal growth near the base. Mushrooms or shelf-like fungi growing at or near the root zone often signal decay inside the wood. The outside of the tree can look fine while the interior is compromised.
- The tree is already in contact with a structure. A tree resting against a roof, fence, or utility line isn't just a future problem. That contact can cause ongoing damage and makes removal more complicated the longer it waits.
- Bark that looks hollowed out or shows insect galleries. Winding tunnels or channels visible under loose bark, along with small exit holes, can indicate a serious infestation that has weakened the tree's structure from within.
Triage: How Soon Should You Act?
Not every tree situation is a true emergency, but some are. The difference usually comes down to three things: what the tree is threatening, how structurally unstable it is, and whether conditions are likely to make things worse before help arrives.
A tree that has already fallen onto a structure, a vehicle, or a utility line needs attention right away. The same applies to a large limb hanging by a thread over a frequently used area, or a tree that has visibly split at the trunk after a storm. These situations carry real risk of further damage or injury, and the right move is to keep people away from the area and contact a qualified tree service professional as soon as possible.
Other situations are serious but allow a bit more time. A tree leaning more than it used to, a major limb that cracked but is still attached, or a tree showing signs of structural decay at the base are all worth addressing promptly, though not necessarily within the hour. A certified arborist can assess whether the tree is stable enough to wait a day or two, or whether removal needs to happen sooner.
The honest answer is that urgency depends heavily on what is nearby. A compromised tree in an open field is a different situation than the same tree positioned over a roof or driveway. When in doubt, keep the area clear and get a professional opinion before making any decisions.
When You're Not Sure
Not every damaged or leaning tree is a true emergency, and it can be genuinely hard to tell from the ground. That's where a professional assessment pays off. An ISA Certified Arborist has the training to look beyond what's visible on the surface, evaluating things like root stability, internal decay, and how the tree's weight is distributed relative to your home or other structures.
A written assessment is worth asking about specifically. Having the evaluation documented gives you something concrete to share with your insurance company and helps you make a more informed decision about next steps.
Credentials matter here. The ISA Certified Arborist designation means the person has passed a standardized exam and keeps their knowledge current. That's different from a general tree-trimming service that may not have formal training in risk evaluation.
One practical note: getting an assessment before a storm season, rather than after a tree has already shifted or cracked, gives you more options. Once a situation becomes urgent, your choices narrow quickly. A proactive evaluation can tell you whether a tree needs to come down now, can wait, or simply needs monitoring over time.
Common Questions
What signs tell me a tree needs emergency removal rather than just trimming?
A few things stand out. Large cracks running through the main trunk, visible root heaving around the base, or a noticeable lean that appeared suddenly are all serious warning signs. So is a tree that has already dropped major limbs without any obvious cause. If the tree is near your home, a vehicle, or a utility line, those concerns become more urgent. A qualified arborist can assess whether removal is genuinely necessary or whether other options exist.

How do South Dakota's severe thunderstorms affect whether a tree becomes an emergency?
Eastern South Dakota sees strong storm systems that can move through quickly and with little warning. High straight-line winds are particularly hard on trees with shallow root systems or existing structural weaknesses. After a significant storm passes through the Brandon area, it is worth walking your property and looking for split branch unions, partially uprooted root plates, or large limbs hanging in the canopy. A hanging limb is sometimes called a "widow maker" by arborists, and it warrants a professional look before anyone works beneath it.

Can the clay-heavy soils common in this part of South Dakota make trees more likely to fail?
Yes, soil type matters more than most homeowners realize. Heavier soils with poor drainage can limit how deeply and widely a tree's roots establish. When roots stay shallow, the tree has less structural anchoring. After periods of heavy rain followed by dry stretches, which are not uncommon in this region, the ground can shift enough to destabilize a tree that looked fine the season before. If you notice soil cracking or lifting around the base of a large tree, that is worth having evaluated.

Does emerald ash borer damage ever create an emergency removal situation?
It can. Emerald ash borer has been confirmed in South Dakota, and ash trees in various stages of decline are present across the region. As the pest progresses through a tree, the wood becomes brittle and structurally compromised. A heavily infested ash may look standing but lose the ability to hold its own weight, especially under wind or ice load. If you have an ash tree showing significant dieback, bark splitting, or heavy woodpecker activity, have a professional assess its structural integrity before the next major weather event.
Next Steps
When a tree comes down or a large limb is hanging over your roof, the next step is straightforward: get a qualified arborist or tree service professional on-site to assess the situation in person. Photos and descriptions only tell part of the story. A professional can check for hidden structural damage, identify secondary hazards you might not notice, and give you a clear picture of what needs to happen and in what order. That assessment also puts you in a better position when dealing with your insurance company. Don't wait on this one. The sooner someone with the right training takes a look, the sooner you can make an informed decision.
