Some trees can grow over a century. Some can't. Some trees growth top out by 50 years and then grow incredibly slowly (sequestering carbon at a much slower rate). Some grow for 300 years and sequester carbon at a constant rate. Which is why it's called woodland _management_.

"Having survived multiple forest fires" says a lot to me. Surviving a forest fire still invokes a huge release of otherwise captured carbon for no gain. Harvesting trees for timber means the bulk of the tree sequesters carbon into the structure, and the waste byproduct can be utilised to provide energy for the process.

With the correct tooling and processes, it's as close to carbon neutral as you can get.
