ABSTRACT
The article discusses the importance of initial spacing of radiata pine based on the evolution of approaches from the 1890s to 1960s and its implications on understanding radiata pine silviculture in New Zealand. Correlating proper initial spacing with a final crop stocking of high quality stems, initial stocking in government plantations began at a rate of 1.2 meters or 7,000 trees per hectare. This was later expanded to 1.8-2.4 meters in 1920 and 1.8-4.8 meters until the early 1950s. Experiments on rectangular spacing in the 1960s failed to show a significant difference from traditional square planting. Observations show that while radiata pine branches grow towards a more open space, initial spacing may vary from the specified spacing with little or no effect on tree growth and form.
