  “Invasive BLACKBERRY

  It chokes out trees, it blocks the sun,
  and kills native plants one by one.

  Pull the roots, cut back the wall,
  And native life will start to sprawl.

  With open ground and sunlight clear,
  The ferns and flowers reappear.”

• What’s the problem with Himalayan blackberry?
  With berries so sweet and plentiful, how could Himalayan blackberry be a problem? Oh, let us count the ways:
  
  • Himalayan blackberry can smother native plants and steal their water and nutrients.
  • The dense, thorny thickets can restrict wildlife movement.
  • When blackberries take over an area and crowd out native plants, they kill food sources that are important for local wildlife.
  • Along rivers and streams, Himalayan blackberry can cause erosion and degrade salmon habitat.
  • Himalayan blackberries can attract rodents. Its dense thickets provides ideal shelter and nesting locations for rodents like rats and mice. And just like humans, they can’t resist the juicy berries.
