Abstract: The paper in the NZ Journal of Forestry, 61(1): 39-40 by Robin Trewin on ‘Forest establishment quality assurance’ plots understates their importance and usefulness. These plots should be established close behind planting gangs by an independent, experienced forester so that bad planters can immediately be identified and recalled for a re-plant (re-work). If the planting stock is not to specification (roots trimmed too short or long, stripped of soil and mycorrhizas or stem diameters too small) the supplying nursery is at fault.
