Thank you very much.
I'm going to move to Dr. Lewis.
You mentioned towards the end of your presentation about the different ways that we harvest forests, such as partial cuts versus clear-cuts.
Can you take a couple of minutes to expand on that? If we're talking about harvesting mature forests or even if we're talking about salvaging forests after a pine beetle infestation, for instance, what are the advantages of not using the clear-cut model?
