The forest industries of the Republic of South Africa depend heavily on introduced tree species such as the American southern pines, slash and loblolly (Pinus elliottii var. elliottii P. taeda.) Because only a very small area is available for high-quality plantations, South Africa has developed an intensive management system which aims for short rotations and high product quality, particularly for sawlogs and peeler logs.

世界林业：南非南部松树的造林

南非共和国的林业严重依赖引进树种，如美国南方松、湿地松和火炬松（Pinus elliottii var. elliottii P. taeda）。由于只有很小的面积可用于高质量的种植园，南非开发了一套集约化管理系统，旨在实现短周期和高产品质量，特别是锯材原木和削皮原木。
