Attributes of the Four-Tree-Cluster Seedling Seed Orchard Design

Characteristics of the four-tree-cluster seedling orchard design are described. Examples are given of possible spacings which could be used and resulting selection differentials. Suggestions are made as to how seedling seed orchard goals are affected by using a four-tree-cluster design rather than a four-tree row-plot design having approximately the same initial number of trees/acre.
