Freeze Tolerant Eucalyptus

Our freeze tolerant tropical Eucalyptus product combines the fast-growing and high-fiber quality characteristics of Brazilian Eucalyptus with the ability to withstand freezingtemperatures. Brazilian Eucalyptus is widely regarded as the fastest growing hardwood fiber and is particularly well-suited for the production of high-quality pulp and paper.  Brazilian Eucalyptus is typically harvested after seven years of growth, yielding an average of 17 green tons per acre per year, as compared to a hardwood tree from a naturally regenerated forest in the United States, which is typically harvested after 40 to 50 years of growth and yields an average of two green tons per acre per year. Our first-generation freeze tolerant tropical Eucalyptus, targeted at the Southeastern United States, is designed to have growth and quality traits comparable to Brazilian Eucalyptus and to grow in areas significantly farther north than the areas in which conventional tropical Eucalyptus is currently grown. Field tests of these trees have survived temperatures as low as 15 to 19 degrees Fahrenheit (minus 6 to 8 degrees centigrade) and therefore allows the tree to be planted in a corridor south of I-10, including in all of Florida, southern parts of Alabama, Mississippi, Georgia, Louisiana and the southern half of Texas.  This product will expand the potential geographical scope of tropical Eucalyptus in the United States by nearly four times, from 15 million to 56 million acres.  While our subtropical Eucalyptus products can also be grown in these areas, based on our field tests, the yields for our freeze tolerant tropical Eucalyptus are 15% to 28% higher than our best-performing subtropical Eucalyptus. Our freeze tolerant tropical Eucalyptus product will have a very large and positive impact on the U.S. commercial forestry industry since it would allow tropical Eucalyptus to be planted over a much greater area in the United States, enabling more land owners and managers to benefit from its beneficial growth and yield characteristics.

These are the results of exposure to freezing temperatures in a laboratory setting. This aerial photo shows the results of freezing temperatures on a field trial of control Eucalyptus and Freeze Tolerant Eucalyptus. The control trees have lost all of their leaves. The surviving trees are Freeze Tolerant Eucalyptus.
