Chapter 15 - Initial Spacing - How Many Trees To Plant
The best initial spacing at which to plant the southern pines is primarily a function of the product desired and is based on both biological and operational factors. Long-term spacing studies over a wide range of initial densities and tree species demonstrate that for rotations beyond approximately 20 years, initial density has little effect on total net wood yield. However, it has a pronounced effect on product size and distribution, value, cost and on harvesting and cultural treatments. Planting seedlings on 2.4 x 2.4 to 3.0 x 3.0 m or equivalent spacing provides good flexibility for plantation management under most landowner objectives and current market conditions.
