Part 4. Growth and Yield Growth and Yield of Some Eucalypts of Interest to California1

For more than 100 years, eucalypts have been generally recognized around the world as among the fastest growing trees. Height growth of 10 m (32 ft) a year during the second or third year of growth has frequently been recorded. Yields 3 of 20 m per ha per year (286 ft/acre/yr) are generally considered as only better than average in Brazil and the Republic of South Africa. Even in California with its long summer drought, some remarkable yields have been measured. In addition, the trees will often grow reasonably well on impoverished sites where other species barely survive.
