THOUGHTS ON YIELD TABLES
The author examines the recently published Forestry Commission Recored Revised Yield Tables for Conifers in Great Britain and shows how the standing volume, basal area, numbers of tress, and mean quarter girth vary with the mean top-height irrespective of age and quality class. By analogy with the Indian Forest Record Multiple Yield Tables for Deodar (Cedrus deodara, Loudon), he concludes that treatment does not materially affect this relationship. A modified yield table for Sitka spruce (Picea sitcbensis(Bong.)Carr.) based on mean top-height only is given.
