Just to clarify, it is “big” trees, not “big, old” trees. Most of the trees in our study were from tropical forest plots for which we had little to no data on tree age. Big trees can be surprisingly young, and small trees surprisingly old...

in a recent paper in the temperate Colchic forest we found beech 250 years old can have diameter <20cm or >100cm (R2=0.33). Relationship of age vs height is even worse (R2=0.26) https://link.springer.com/article/10.1007/s10021-019-00462-x …pic.twitter.com/eZi120a4Vm

I would have thought that was obvious

You would think so but Sheffield council didn t think so when justifying felling thousands of street trees ! They told us planting 2 saplings for every mature tree felled was enough.Luckily residents stood up to their bullying ways tho many were arrested in the process.

Young Trees Grow Fast. Big Old Trees are growing Slower. Size Matters in this instance!! Big, Old Trees by their very Height, Diameter, Surface Area, Needles and Branchlets have way more wood that needs to be "Put On" Each Year For Each Growth Ring & the Expanding Bark!!!

All irrelevant unless there is a plan on what the trees are going to be used for. If coppiced and burnt it’s ultimately back in the atmosphere. In truth it’s just the soil that’s locking carbon up permanently

It has been and is for those of us managing woodland and you pretty much need the full age range for resilient woodland succession.

I always thought veteran trees were important!
-
Indeed they are, but maybe more as home, refugia or shelters for biodiversity (a lot of insects and epiphytes rely on veteran trees for their habitats) than as active carbon pumps. Young big trees should be more efficient than big old ones for pumping carbon from the atmosphere
