The main pines at Pinsongqiu, Daliang County, Shunde in China were that of Pinus massoniana (马尾松) which are commonly known as the Chinese red pine, Masson’s pine or horsetail pine. They are a species native to Taiwan, central and southern China and Hong Kong plus northern Vietnam. In their natural environment they grow at low altitudes below 1,500 metres.

One key feature on researching the Pinus massoniana was that of a potential concern in pine woods of this species with nematodes and there is currently a survey to explore the concerns and impacts on this species by nematodes and the wider impacts on importing and exporting plus inspections and quarantine on bonsai and potted plants.
