We can estimate the age of young conifers by counting the levels or whorls of branches. Each new whorl represents a year’s growth.
It is less well known that we can see evidence of this growth in older trees that have shed these branches.
The image of a Monkey Puzzle tree’s bark below shows the rings on the bark where a whorl of branches once grew. The gap between the rings gives an indication of the growth that year and whether it was good or tough one for the tree.
My thanks to Mandy for this image of the tree from Cadiz, Andalusia, Spain.
