It’s fast-growing and drought-tolerant, producing tons of biomass per acre. It thrives even in poor soil and is a self-propagating perennial, so it requires little investment once established.
To people in the renewable fuels industry, Arundo donax – also known as “giant reed” – is nothing short of a miracle plant. An Oregon power plant is looking at it as a potential substitute for coal, and North Carolina boosters are salivating over the prospect of an ethanol bio-refinery that would bring millions of dollars in investment and dozens of high-paying jobs to hog country.
But to many scientists and environmentalists, Arundo looks less like a miracle than a nightmare waiting to happen. Officials in at least three states have banned the bamboo-like grass as a “noxious weed”; California has spent more than $70 million trying to eradicate it. The federal government has labeled it a “high risk” for invasiveness.
Many are comparing Arundo, which can reach heights of 30 feet in a single season, to another aggressive Asian transplant – the voracious kudzu vine.
More than 200 scientists recently sent a letter to the heads of federal agencies including the Environmental Protection Agency and the Departments of Agriculture and Energy, urging them not to encourage the commercial planting of known invasives like Arundo.
Gee, maybe it’ll be obliterated from earth and we’ll all have to try a new profession. Ya think?
