Genetically Engineered Eucalyptus

They're trying to attract bigger contracts from paper and mulch companies.

I don't think they've stopped to consider the ecological context or the impact of eucalyptus oil. Koala bears are almost the only critter that CAN eat eucalyptus, along with a few well-adapted insect pests. The oil repels most herbivores and insects; even in Australia, not much eats that plant. Not much grows near it, either; eucalyptus groves tend to suppress many competing plants. Also, the oil is extremely flammable; if the trees catch fire, they can explode. The fallen bark remains flammable because it doesn't break down quickly; the oil discourages fungi.

Eucalyptus has been introduced to many warm areas outside of Australia because it's profitable. But it shows a pattern of becoming an invasive nuisance.
