Cut branches off an ash tree

my neighbour has cut a large branch off the side of my ash tree that was over hanging his fence (which is fine ok with me) however I had told him I wanted to consult a tree surgeon before he went ahead as I was unsure what effect cutting such a large branch would have on the tree. He has cut most of one of three main branches off leaving about two meters of it, and cut all the smaller branches off it leaving it the two meter section bald pointing in the air regardless.
is this likely to cause any major problems for the tree?

many thanks

If your neighbour has not cut to a growth point then yes it could be a slight problem.

In order to help avoid colonization by decay organisms and pathogens the cut should of been made just outside the branch collar (if visible). This will minimise the chances of pathogens attacking the tree as its at the optimum point for the tree to cover its wound over time ( known as CODIT). Without seeing the tree it shouldn't cause any major problems. The tree will respond and if it wasn't cut back to a growth point or branch collar it will probably produce rapid new growth know as epicormic shoots which are usually straight.

If a large branch is cut back to a long stub without any healthy growth points (i.e side branches with leaves on) it's quite likely to die back, especially an Ash tree. The tree as a whole should be fine, but if the branch dies back, the dead wood can become a hazard to anything below that if might fall on.

Any species of tree ideally wants any branch/ limb cut back to appropriate growth points. This is a point on the limb where there is growth but minimum size of 30% of the size of the branch being cut. If it’s being cut to no growth points at all it can recover but will shoot out stress growth which isn’t great for the tree and can cause die back. People are within their right to cut back trees to their boundary but within reason and with consulting the owner of the tree. The larger the limbs being cut the more likely the tree will suffer so it would always be best to consult a professional before work being carried out.

Alot of hardwood trees are fairly resilient but good practice is always to prune branches back to a suitable growth point. When we talk about about a “suitable growth point” it means to prune the branch back to Something at least a 1/3 the diameter of what you have removed. This helps the wound ‘compartmentalise” and heal correctly.
