Below is a photo of what’s called a bifurcated tree, where two co-dominant stems are competing to be the dominant trunk. Why this is something to look out for is because it is only a matter of time before one of the stems is likely to fall, if not taken care of soon.
Here you can see there is a lot of overlap of the two stems pushing up against each other, and the more the tree grows the more either stem has a tendency to fall.
While this should have been looked after when the tree was juvenile, there are still a lot of preventative measures that can be taken to minimise the risk of either stem falling, such as cable bracing or weight reduction pruning.
This other example shows the same tree with another bifurcation, however you can see neither of the stems are touching, which decreases the chance of potential failures. While this doesn’t eliminate the risk, it is still something to be wary of as most stems typically have all of their weight leaning toward one side.

A note on cable braces..
You may have a cable brace installed in one of your trees.. one thing to be mindful of is that they aren’t meant to be static or under tension - there should be a little bit of free play so the two stems can move about in the wind as they normally would without them (cable braces are designed to stop stems from reaching the point of breakage)
While they are designed to be installed this way, after a few years of tree growth, a lot of the time they are forgotten about and subsequently end up under lots of tension. This can be extremely problematic as trees get their strength from adding more wood to the parts where there is movement - if there is no movement (as a result of static cable braces) then the tree is no longer adding wood to where it is needed.. if that makes sense
Hope this helps :) if you have any queries, by all means reach out to us by calling 0478 896 636 or emailing us at firstname.lastname@example.org.
