What Signs Do Trees Have That They Are Dangerous?

What Signs Do Trees Have That They Are Dangerous?

If you live in an area with trees, chances are good that at some point you’ll need to know how to spot a dangerous tree. 

It’s always best to avoid this situation in the first place, but if you do find yourself looking up and wondering whether it’s safe to walk under that branch, here are some ways to tell and choose the right Tree Arborist Adelaide.

Basal cracks

Basal or root cracks are usually caused by poor soil quality, poor drainage, and root damage. These cracks can also be a sign of tree age.

If you have a tree that has basal or root cracks it is important to get them checked out as soon as possible. These types of cracks can cause major problems for the stability of your tree and could lead to failure if not taken care of properly.

Top die back

Top die back refers to the loss of a tree’s crown or upper branches. This can be caused by a number of factors, including:

  • Root rot or other phytotoxic diseases
  • Mechanical damage from lawn mowers and other equipment
  • Insect infestations like non-native species such as gypsy moth larvae (which feed on leaves) and bark beetles that burrow beneath the bark
  • Environmental conditions like drought, which can cause water stress to trees


Cavities are holes in the trunk or branches of a tree caused by decay. Cavities can be caused by insects, disease or decay. If you see cavities on your trees it could be a sign of a serious health problem and should be treated right away with the help of Arborist Adelaide.


Often times when trees have cavities they are weakened by this condition and could fall over if too much stress is put on them. This is why it’s important for homeowners to keep an eye out for any signs that their trees need help!

Dead limbs and branches

If your tree has dead limbs or branches, that’s a sign of decay. Dead limbs can pose a hazard to people and property, so if you notice any on your trees, it’s time to get them removed. The same goes for dead branches—they can fall off as easily as they grow back on, and there’s no use in letting them hang around if they have no purpose or future.

If you see signs of decay in the form of dead branches or limbs and you don’t feel comfortable removing them yourself, then consider using another service provider such as Lawn Love. They’ll provide fast, efficient services from expert tree professionals at an affordable price


Fungi are a common cause of tree decline. Fungi can be a problem for trees in urban areas, rural areas and arid areas.

Loss of foliage

If you notice your trees have lost their leaves prematurely or if the leaves are turning yellow and falling off, it is possible that they are suffering from a disease. However, this is not always the case. 

For example, certain insects can cause trees to lose their foliage as well. If you notice this happening on your tree or if you think there may be some type of pest infestation in your yard or garden area that could potentially damage your trees, contact an arborist immediately.
