> Additionally timber likes to make claims like "we plant 2 trees for every 1 harvested." What they don't tell you is that half the trees won't make it to the next clear, and often smaller/weaker/sick trees are culled before a full clear to make room for better ones to grow.
Sure, but the number of trees doesn't matter so much -- the amount of carbon sequestered by those trees is more important. Presumably, thinning out the weak trees allows the stronger trees to grow larger.
The US timber industry is actually pretty good for sequestering carbon because their economic incentives lead them to:
- Select fast-growing species of trees
- Harvest the trees before they reach their terminal state (when they stop acting as a carbon sink), then replant new trees.
- Promote the use of timber products as substitutes for carbon-intensive building materials, like concrete.
There was an interesting life-cycle analysis of this published a few years back:

- dexwiz 4y agoThinning out weak to let the strong grow is standard forestry practice. No one expects 100% of saplings planted to mature into fully grown trees. I am just saying, don't believe timber industry numbers on face value. The 2 or 3 trees planted for each tree harvested does not translate into a net increase of forest size. If you compare forest numbers in the USA now to 50/100 years ago, we have seen tremendous growth. However, the number has stabilized in the last few decades.
