According to David, by mimicking nature to reinvigorate or thin heavy canopies, the best method is to prune or lop at the points that would naturally snap and fall in high winds.
This process, he refers to as "tree morphogenus".
This makes perfect sense. Nature does reduce and thin tree canopies, as evidenced everytime we have high winds here in Ballarat. Good tree maintainance and knowledge of branches vulnerable to snapping can avert disaster and dangers in advance of the occurance, avoiding unnecessary danger and heartache through wind damage. This is especially true with our eucalypts, who shed branches when they get too heavy, often on warm, still days, as well as in high winds, adjusting to local variations in climate, water and soil conditions.
David endeavours to maintain the natural form of the tree, even when canopy reduction and lifting is considerable. In suburban backyards, making the most of available light and safety are important, particularly, if you have a large mature tree that dominates your garden. David advocates such trees should be maintained, thinned and undergo canopy lifts, rather than be removed.
David has written several books on trees and maintaining them according to the rules of nature. He has developed high quality courses and curriculum about trees that he runs in schools in England, as well as maintaining his Arbornaughts, arborist service and a timberyard, dedicated to supplying wood taken only from the trees he prunes, for construction and turning.
He credits trees with transforming his life. Clearly, David is a man passionate about trees and ensuring all timber he removes from the trees he tends is recycled into fine furniture and housing materials.
