The sustainability of indigenous Monterey pine (Pinus radiata D. Don)at Ano Nuevo stands in the central coast of California was examined. The foremost management objective in these stands is to establish and maintain stand structures that ensure a sustainable presence of the species in terms of uneven-aged management.
