Penn State Live - Researchers learn why invasive plants are spreading rapidly in forests
excerpt from above:
Quote:
University Park, Pa. -- Invasive plants are advancing into Eastern forests at an alarming rate, and the rapid spread has been linked by researchers in Penn State's College of Agricultural Sciences to forest road maintenance and the type of dirt and stone used on roads.

Perhaps predictably, according to David Mortensen, a professor of weed ecology who has been studying the spread of invasive plants for nearly two decades, humans are unwittingly accelerating the relentless march of invasives into even isolated forests...

That's not the only reason why they're spreading so fast. You should see some of the seed mixes approved for use for roadsides. What a joke.
