Learn Why Invasive Plants are Spreading Rapidly in Forests (Dec 10,
2009) PennState Live. University Park.
Researchers at Penn State's College of
Agricultural Sciences have linked the rapid spread of invasive plants
in Eastern forests to forest road maintenance and the type of dirt and
stone used on roads. Perhaps the most startling finding of the research
"Forest
Roads Facilitate the Spread of Invasive Plants," (Invasive
Plant Science and Management (Jul/Sep 2009) relates to the nature
of dirt and gravel on forest roads that enables invasive plants such
as Japanese
stiltgrass to thrive.
