Terrestrial
Invasive
Species
11.1
Extent
and rate
of spread
Few (less than 10
percent) or no
populations of terrestrial
invasive species infest
the watershed. Those
that occur are small in
extent and scattered
in nature. The rate of
spread and/ or potential
for impact on watershed
resources is minimal or
unlikely.
Populations of terrestrial
invasive species are
established within (10 to
25 percent) the
watershed and/or the
rate of spread and/or
potential for impact on
soil, vegetation, or other
water resources is
moderate. Treatments
must be ongoing.
Populations of terrestrial
invasive species infest
significant portions
(more than 25 percent)
of the watershed, may
be expanding their
range, and widespread
impacts to soil, native
vegetation, or other
water resources have
been documented.
Treatments need to be
ongoing.

Forest
Health
12.1 Insects
and
disease
Less than 20 percent
of the forested land
in the watershed is at
imminent risk of
abnormally high levels
of tree mortality (25%
in a stand) because of
insects and disease.
Between 20 and 40
percent of the
forested land in the
watershed is at
imminent risk of
abnormally high
levels of tree mortality
(25% in a stand)
because of insects and
disease.
More than 40 percent
of the forested land
in the watershed is at
imminent risk of
abnormally high levels
of tree mortality (25%
in a stand) because of
insects and disease.
12.2 Ozone
Ozone causes a
decrease in biomass
growth in fewer than
20 percent of the
years evaluated.
Ozone causes a
decrease in biomass
growth in 20 to 40
percent of the years
evaluated.
Ozone causes a
decrease in biomass
growth in more than
40 percent of the
years evaluated,
and/or the watershed
area exceeds Air
Quality Standards for
ground-level ozone.

12. Ozone Damage
• Evaluate ozone levels (stressor)
• Identify sensitive tree species
• Identify species presence in watershed
• Evaluate ozone risk

15. Next Steps:
Collaboration and Citizen Science
Information is shared
among organizations
through the Midwest
Invasive Species
Information Network
(MISIN) Treatment
Tracking database

16. Next Steps:
Collaboration and Citizen Science
European Alien Species
Information Network
(EASIN) has mapping
services through data
partners, and includes a
citizen science
component.
