Some of the most commonly recommended species for biofuels production are also major invasive alien species. The quick growth and need for little maintenance that make some grasses attractive as biofuels also make them liable to spread where they're unwanted.

Invasion of the Spiny Water Fleas (May 6, 2008)
Queen's University (Canada).
