One thing has proved consistent in landscape and urban forest, that fast growing is on par with weak trunks and limbs. And storms hammer on the weak trees. Usually, the trees I kept track of that grew slower and were not fertilized to boost growth ended up with less damage.

In the wild, among groves, it may be a completely different resulte than isolated urban trees. It may take a second century to show what fast growth really means in forests around the world.

Hi All

Today we climbed and confirmed the 1939 regrowth tree at 90.69m tall. ... -news.html

The tree is a picture of health and vitality - it has this peculiar habit (for E. regnans) of healing over where dead branches have broken off in protruding cones .
With E. regnans, speed and size are everything. If you are suppressed, you die. Millions of seedlings per hectare pop up after a fire. Only the biggest,fastest and luckiest get to reach maturity. Around this tree are the remains of 1939 trees that couldn't keep up. The wood is very strong and flexible. This tree is nicely protected from prevailing winds by tall neighbors and its position near the gully. It also survived a scare many years ago when an old stag smashed down right next to it.

Has anyone dared try to calculate the carbon content of some of these monsters and rates of acquisition? The average height growth of the 78-year old eucalyptus is 1.163 meters. Do you have a feel for the height growth rate over time? Volume?

there have been a number of papers on Carbon storage in E. regnans forests. two of which are listed below:

Re-evaluation of forest biomass carbon stocks and
lessons from the world’s most carbon-dense forests
Heather Keith1, Brendan G. Mackey, and David B. Lindenmayer
The Fenner School of Environment and Society, Australian National University, Canberra, ACT 0200, Australia

Carbon in Trees in Tasmanian State Forest
M. T. Moroni, T. H. Kelley, and M. L. McLarin
Forestry Tasmania, 79 Melville Street, Hobart TAS 7000, Australia

Height growth rate slows down as the tree reaches 50-60 years of age. I expect the tallest regrowth trees to be adding a meter of growth every 3-4 years. The wood volume of the trunk would be in the range of 22-26m3 for 'the 1939 tree and 25-30 for the 1926 tree
