Uwe, it's a seasonal process, it is regrown during the colder months.
Jesito, it was taken with the 50 - 500mm.
These trees grow straight and tall and in the old days were used for ships masts, in coastal locations. When I lived near Melbourne, close to the southern coast, a road on the edge of our town had the name "Mast Gully Road".
Sincere regards, Jim Roelofs
