 At that stage, softwoods were still being imported in large quantities and it was also believed that softwoods could not only relieve the pressure on native forests but make Australia self-sufficient in timber resources.In addition to the more dominant Radiata Pine plantations, a number of small trial plots of different conifer species were tried in the Aire Valley during the 1930s including Sitka Spruce, Canary Island Pine, Bishop Pine, Corsican Pine, Western Yellow Pine, Douglas Fir and Coast Redwood.Six trial plots of Coast Redwoods, "Sequoia sempervirens", were planted between 1929 and 1936.
