Managed Ecosystems and Biofuels A Subject of Current Interest and Concern

Some vegetation classification schemes have developed algorithms to distinguish between wooded C4 grasslands, wooded C3 grasslands, and C3 grasslands. These categories may become particularly important in the future to assess the impact of grasses and woody species being considered for biofuel production. Several grasses and woody species have been evaluated for biofuel production, with perennial rhizomatous grasses showing the most economic promise. Arundo donax (giant reed; native to Asia) and Philaris arundinacea (reed canary grass; native to temperate Europe, Asia, and North America) are two C3 grasses being considered as biofuel species that are invasive in some US ecosystems. The former threatens riparian areas and alters fire cycles; the latter invades wetlands and affects wildlife habitat. The hybrid Miscanthus x giganteus (native to Asia) and Panicum virga-tum (switchgrass; native to central and eastern US) are C4 grasses being considered in Europe and the US. Several Miscanthus species are invasive or have invasive potential. Several traits that make these C3 grasses potentially valuable as a crop could also enhance invasiveness (ability to sprout from rhizomes, efficient photosynthetic mechanisms, and rapid growth rates). Thus, they have the potential to adversely impact local ecosystems while adding to fire susceptibility.
