Want to know Gum Trees? Part 2

So my first tip to identifying gums was to become familiar with an area. Walk and look at the trees until you can see which ones are similar. Before too long it won't look like a wall of green anymore.

So my next tip is to keep looking and walking and becoming familiar but now pay attention to the bark. The bark is a key identifying tip, especially when it comes to gum trees. I'll talk more about gum trees soon but for now start to notice the bark. I've added some photos below of what types of bark you may come across, particularly in the bush of Brisbane and surrounds. Again I wouldn't worry about taking out your ID book or trying to name any of the trees. I'd just look at the bark.


Smooth Bark
 
 
Iron Bark
 
 
Stringy Bark
 
 
Box Bark
 
 
Bloodwood Bark
 
 
Here I have introduced five bark types. Smooth, Iron, Stringy, Box and Bloodwood. See how each of the bark types are rather unique? Looking at the bark type is a key identifying feature, which can help you narrow down what type of tree you are looking at.
 
Now next time you go for a walk, have a feel of the bark on the trees. Does it come off in strings or flakes? Is it smooth or rough and difficult to pull off? The other thing to look for, is if the bark is rough or smooth over the whole tree or only some of the tree. Perhaps there is rough bark only at the base and it's smooth further up the trunk. The photo below is what a half bark might look like. Rough at the bottom but smooth further up the trunk. So take a few days and look at the bark of trees.
 
 


Half Bark

  1. I have noticed a lot of the smooth barked gums around here are dropping their bark everywhere. It looks like the tree is bursting out of its skin. The bark is cracking into pieces and flaking off. Is this just what those trees do or does it have something to do with the weather?

  2. Yes most eucalyptus trees will shed their bark yearly.

  3. What is the scientific name for the half bark gum tree?

  4. Half bark is the description of the bark type only. So the lower half will be rough bark and the top will be smooth. The tree in the picture is a Moreton Bay Ash Corymbia tessellaris.
