So, will we ever get rid of these alien invaders?
That’s a tricky question, since cutting some species at the wrong time can just spread seeds and encourage growth. Others grow by spreading rhizomes underground, so cutting what is visible aboveground can just encourage more rapid spreading underground.
While we have little hope of getting rid of these species altogether, what we can do is keep them under control enough to allow our natives to survive and give nature a chance to come up with its own remedies.
In time, most species develop predators. A rust is already attacking multiflora rose. Some local haters of this prickly species have gone so far as to transplant infected plants from other areas into patches of the species on their properties to help nature along. Of course, trying to “help" nature is partly what has gotten us into this fix to begin with, so this style of warfare has its own potential to create problems.
And what do we do with ’ exotic plants once we cut them • or pull them from the ground? * Burning pollutes the air; and composting may help them
