The camphor tree (Cinnamomum camphora), also known as camphor laurel, is an exotic that has been widely cultivated for more than a century as a shade and ornamental tree in Australia. This is the aromatic tree from which camphor was derived (used in medicines and mothballs), until camphor oil began to be made artificially in the 1920s. The camphor quickly grows into a good-looking shade tree which is frequented by berry-eating birds. Camphor laurel is native to China and Japan where it has been commercially used for its timber and essential oils for hundreds of years. 

Recently, land managers have come to realize that, outside China and Japan, camphor trees grow like weeds, infesting forests and displacing native trees. This is because camphor trees are prolific seed producers that do not have serious predators or diseases outside their native range. Camphor trees are taking over forests in Australia, where they were introduced in the early 1800s.

Roundup fact sheet
Roundup is a non-selective herbicide used to kill unwanted grasses and weeds. It is available in professional strength liquid concentrate and professional dry concentrate formulations. When Roundup is sprayed on plant foliage, it is absorbed and then moved — or translocated — throughout the plant’s tissues. Once inside the plant, Glyphosate (the active ingredient in Roundup) inhibits the production of an enzyme, called EPSP synthase, which in turn prevents the plant from manufacturing certain aromatic amino acids essential for plant growth and life. Glyphosate interrupts the metabolic process in plants, so its effect may not be visible for about four days in annual plants and up to seven days in perennial plants. After application, the plant wilts and turns yellow, and then turns brown as the plant tissue deteriorates. At the same time, Glyphosate decomposes the plant’s underground roots and rhizomes. Ultimately, the entire plant dies, is incapable of regenerating, and enriches the soil as it decomposes.
Tests have shown that Roundup, when used according to label directions, has no weed killing activity once in contact with the soil. Glyphosate will not move in or on the soil to affect non-target vegetation, and it does not move through the soil to enter other non-target plants by the root system. Glyphosate is only effective when it comes into contact with the green, growing parts of plants. Other tests have shown that Glyphosate binds tightly to most soil particles until it is degraded. This means that the likelihood of Roundup harming nearby plants is negligible, and there is an extremely low potential for Glyphosate to move into groundwater.
