This week, I have provided my readers with three informative videos on invasive plants.  The first, from University of Pennsylvania, discusses the impacts of invasive plants in the Northeast region of the United States.  It provides examples of three species, Tree of Heaven, Autumn Olive, and Japanese Barberry and gives the best way to eradicate them.  The second is a video from a Vancouver, British Columbia Canadian news station that talks about some of the invasive plants affecting native Canadian ecosystems.  The third video is from UC Davis at the American River Parkway in California, which is very close to where I live.  It talks about a few of the invasives affecting California and how they are changing the native diversity there.  All of the videos are under five minutes long and illustrate how invasive plants are spread and what we as environmentally concious citizens can do to prevent this.  Please watch and enjoy!
