A few months ago, I came across this oak tree. It sat within a field grazed by cows during the summer months. It’s certainly a fantastic example of how retrenchment of the crown occurs, and it appears to have fully completed this retrenchment ‘spurt’ (it may well have more ‘spurts’ in the future). At the lowest extremity of the crown, we can also see the ‘grazing line’, which I find adds to the tree’s character. I’ll let the picture do most of the talking, here.
