If you remove a mature tree and replace it with a young one, you will actually increase uptake as the growing tree will absorb more CO2 than a mature one will.
However, I agree that it is complex because you need to take a long term view and there are always risks. For example a wild fire would offsetting the equation as the young trees are more vulnerable.
It’s probably more complex than this. For example, every tree you remove mean less carbon capture in the world.
it depends on whether that tree is re-planted.
