Until they burn or rot and release the carbon back into the air
Also trees only grow where trees grew in the past, so growing new forests will only capture the carbon that was released when the old forest there was burnt or cut
If you want to capture the most of the carbon, you cook the wood in an oxygen free environment turning it to charcoal and liberating volatile components (which could be used as carbon neutral fuel to run the furnaces)
Nothing can eat charcoal, so it could be stored cheaply

Decomp still sequesters carbon.
Sure, burning them releases a portion back, but not most of it…
What do you think comprises ash?
