I read The Hidden Life Of Trees a while back. I believe the author suggests that old growth forests are bigger carbon sinks because they have deeper humus [1]. I don’t know the merits of that idea but it helped me realize that when people talked about forests, I was only thinking about the trees themselves, not taking the soil into consideration, too. If that idea has merit and the research does eventually conclude that forests are a carbon sink strategy, then it suggests that preserving old growth forests might be more effective than planting new ones.
