JARMAN'S "STANDING STEM HARVESTING" technique does seem a cleat improvement in helicopter logging. How can it make the best contribution to forestry over-all? Zero-impact logging doesn't exist. Positive-impact logging can, at least sometimes. Merve Wilkinson (personal communication) found that as he managed his "Wildwood" the stand quality and in particular, the stocking pattern, improved toward optimum from the near-old-growth conditions with which he began. No-intervention, nature-only "management" produces, although not ideal, a result so much better than clearcut-and-wait, or even clearcut-plant-seedlings-release-twice-and-wait.
