Restrictions to Slow Spread of NNIS
Non-native
invasive species (NNIS) are plants, animals, insects or other organisms
whose introduction to an area does or is likely to cause economic or
environmental harm or harm to human health. Other names for NNIS
include exotic species, noxious weeds, pests, etc. A few
examples of NNIS that occur in Minnesota include purple loosestrife,
gypsy moth, Eurasian waterfmilfoil, earthworms, rusty crayfish, and
common buckthorn.
Unlike
much of the U.S., the Arrowhead Region and the Superior National Forest
are fortunate because many of the species that are a problem in the
upper Midwest are not well established here yet. However, NNIS
can quickly spread once introduced into the environment. NNIS
can spread on the air, in the water, and on articles like campers, firewood,
boats, vehicles, even the mud on your boots.
Because
non-native invasive species do not respect property lines, we are working
with other agencies, non-governmental organizations, and citizens like
you to increase awareness of this resource management issue and take
action to stop the spread of NNIS in our area.
