Invasive species expert briefs congressional staffers on the benefits and risks of biofuel crops

A Virginia Tech invasive plant expert will be briefing congressional staff members on Monday on the best ways to increase the use of plants for biofuels without sewing an environmental nightmare in the process. 

While plants used for biofuels are a vital part of a growing need to create more forms of alternative energy, careless planting of them can lead to an unwanted invasion of exotic plants that can push out native species and create ecological havoc. 

“We hope to show our leaders in Washington how a series of simple procedures can maximize the benefit of the biofuel crops while mitigating their risks,” said Jacob Barney, an assistant professor in the College of Agriculture and Life SciencesDepartment of Plant Pathology, Physiology, and Weed Science

History has shown that crops that were meant to have a benefit can turn out to be a nuisance. Kudzu was introduced to curb erosion but now chokes out native plants in large swaths of the South. 

Barney is the leader of an international group of scientists who have been working on the proposal as excitement and concern surrounds biofuels. 


The excitement comes from farmers wanting to diversify their crops by planting biofuels, which can often be raised on marginal land with little inputs. But the fear arises if those crops could be deemed invasive, which is one of the top-five threats to biodiversity. Once an invasive plant takes root, it can be extremely difficult and costly to remove them. 

Barney and his colleagues are proposing a multi-step risk-evaluation system to determine if crops pose an invasive risk. It examines if plants are considered “weeds,” if it requires quarantining, and what laws exist or are needed to minimize risk. 

“We hope our time in Washington will help to move the biofuels market ahead in direction that helps the planet instead of harming it,” said Barney, who is also a member of the Fralin Life Science Institute.
