Biological wildfire. The green cancer. For invasive plants, scientists say, these labels may even be understatements since, over time, non-native plant invasions can spread to unmanageable levels, often leaving extinctions and altered ecosystems in their wake. And, they cost the U.S. billions of dollars annually while presenting an ecological threat that researchers say is second only to habitat d
