These ”critical uptakes” are expressions of how much the forest can take up without depleting the soil. If the critical uptake is adjusted to management and inverted, the sustainable harvest can be estimated. Thus

Matters of biodiversity are as yet to be investigated. It is reasonable, however, to expect there to be better possibilities f
