Your final plantation design plan should include acreage, species, number of trees ordered, spacing, arrangement, site preparation, and method of planting. Ideally, a plantation should be designed to provide financial return, aesthetics, wildlife needs, and diversity through proper design.
Height growth is reduced at extremely high and low densities.
Diameter growth is unaffected by spacing until competition begins. The period of fast, early diameter growth is longer at wider spacings. Wide spacing will also result in branch retention leading to knotty woods. Spacing may also be affected by which species you select to regenerate. Relative shade tolerance and the species growth pattern will affect initial spacing.
