There is increasing interest in managing Eucalyptus nitens plantations for sawn timber production. Shining gum is difficult to dry with moderate shrinkage and a high cell collapse necessitating reconditioning. Toxicological studies (in six laboratories) reported on the Australian Broadcasting Corporation's Australian Story program Feb 2010[14][15] found that the surface scum (foam) collected from a river supplying water to a Tasmanian town kills water fleas, mollusc larvae and human cell lines, and it was reported on the same program that "a large increase in cancer sufferers and a lot of people with rheumatoid arthritis, scleroderma, lupus" might have the same cause.
