Guys, this is a cut & paste but thought you might be interested.

Genetic engineering is coming to the forests.
While the practice of splicing foreign DNA into food crops has become common in corn and soy, few companies or researchers have dared to apply genetic engineering to plants that provide an essential strut of the U.S. economy, trees.
But that will soon change. Two industry giants, International Paper Co. and MeadWestvaco Corp., are planning to transform plantation forests of the southeastern United States by replacing native pine with genetically engineered eucalyptus, a rapidly growing Australian tree that in its conventional strains now dominates the tropical timber industry.
The companies' push into genetically modified trees, led by their joint biotech venture, ArborGen LLC, looks to overcome several hurdles for the first time. Most prominently, they are banking on a controversial gene splice that restricts trees' ability to reproduce, meant to allay fears of bioengineered eucalyptus turning invasive and overtaking native forests.
If such a fertility control technology -- which has come under fire in farming for fear seed firms will exploit it -- is proven effective, it could open the door to many varieties of wild plants, including weedy grasses, to be genetically engineered for use in energy applications like biomass and next-generation biofuels without fear of invasiveness.
The use of such perennial plants -- so named because, unlike annual farm crops, they live and grow for many years -- has long interested business and government, including the Energy Department, which has collaborated with ArborGen. The plants, which include many grasses targeted for cellulosic ethanol, can be harvested when needed and, given their hardiness, grow on marginal land.
Yet many questions remain about the effectiveness of the fertility system used by ArborGen, which, according to leading scientists, has never been rigorously studied in multiyear trials to prove that it can effectively control plants' spread. More research must be conducted before such systems are relied upon to restrict pollen and seed spread, they say.
Despite these calls, ArborGen has been seeking government deregulation of its eucalyptus, which is primarily engineered to resist freezing temperatures, since 2008. If successful, ArborGen would likely revolutionize the timber industry and the Southern landscape by becoming the first company to roll out bioengineered trees on a massive scale, observers say.
In its rosiest scenarios, growers using ArborGen's presumably expensive seeds would see huge gains in productivity and become the preferred tree stock for a new generation of bioenergy refineries. The South would become the new Appalachia; timber would serve as its coal. Inklings of such progress have already arisen, including recent word that the German utility RWE AG would build the world's largest wood-pellet plant in Georgia to supplement its coal habits.
By adopting eucalyptus as a tree stock, the United States would simply be catching up with countries like Brazil, which has leveraged vast tree plantations in recent decades to pivot from a net wood importer to an exporter. While the South saw a rise in pine plantations during this time, pine cannot compete with eucalyptus for sheer growth rate, the company says.
 
I dont wont shoot the messenger, but high rotation moncultural plantings are going to really pound the soil. They can get away with it for a couple of generations, but there are nutrients that get taken away from the soils everytime a tree is hauled away. If the slash is left in the woods it helps, but generally these plantations take the whole tree. There has been some interesting studies done in New England on former farm land that reverted to woods many decades ago and soils scientists can still distinctly see missing consituents of healthy soil compared to areas that were never farmed.

One of the other genetic manipulations is to make trees with weak lignin so they turn into pulp better, unfortunately when there is weak lignin, the tress tedn to fall over in the wind.
 
I can't find a BTU listing for eucalyptus........doesn't sound promising.
 
Just like any other wood, Eucalyptus will burn just fine if properly seasoned. I know that lots of folks in California burn it, and I would imagine lots more in Australia burn it. The following link is from a California based site, so keep in mind that the table of wood burning heat values includes only those woods commonly available to us west-coasters. Having grown up in California, I'm very familiar with the tree. For a softwood, it's dense. Up here in Oregon, we can't get Eucalyptus. After scoping out this chart, I wish we could. Rick

Did I misread your post? Sounds like this is all going towards biomass fuel. Of course it has btus, but will it be burning in your stove?

Well I do live in the southeast and a split or two could end up in my woodpile somehow. Good news on the btu value, it does sound promising.

I just thought the concept was interesting but I am a proponet of maintaining native vegetation where possible. This area is a longleaf/wiregrass/hardwood strand ecosystem in its native form.

We already have melalucka, brazilian pepper and kudzu.
