An individual tree is neutral, but a forest is carbon negative as long as it exists.

Untrue.
Just letting a forest grow wild is carbon neutral. The soil reaches a point of saturation. Eventually the dead trees get eaten by detritivores, releasing the captured carbon back into the air.
Keeping it sequestered long term requires burying it deep - the trees would need to be cut down and transported to where bacteria, fungus, and so on can't eat them.

  • forest does not exist. Carbon is in atmosphere
  • forest grows, carbon is bound up in whatever lives in the forest
  • forest reaches steady state, carbon emitted by decomposition is balanced out by new growth

It’s net negative as long as it exists. What I said is true.
