How to use it

For square spacing, divide 43,560 square feet by the area occupied by each tree. Real planting totals should account for roads, wet areas, boundaries, mortality, and operational spacing.

Planning estimate: Field conditions, sampling method, tree form, defects, and local forestry standards can materially change results. Use professional cruising and appraisal methods for timber-sale decisions.
