Abstract: NATIVE POPULATION GROWING CONDITIONS Native population of radiata pine occur in California at Ano Nuevo, Monterey, and Cambria. There are also two island populations on Guadalupe Island and Cedros Island (Shelbourne et al. 1979). The climatic conditions of the mainland populations are (Offord 1964, Scott 1960 as quoted in Lavery 1986): typical Mediterranean climate; 400-800mm of annual rainfall, which is strongly seasonal in distribution with 70% of the rain falling in winter; limited frosts, with hard frosts restricted to the winter months; and no snow or hail. UPDATE WARNING: Significant parts of the Forestry Handbook were produced in 2005. The NZ Institute of Forestry is currently reviewing the future strategy and role for the handbook. In the meantime, some subject areas have been removed as they no longer provide accurate information. Remaining subject areas provide some relevance and/or guidance but users must take cognisance of the fact that information is now dated and in many places does not now reflect the entirety of modern knowledge and technology being applied to the management of New Zealand’s forests.
