    As defined by the Invasive Species Advisory Council, an invasive species is a non-native species
whose introduction does or is likely to cause economic or environmental harm or harm to human, animal
or plant health.
    Non-native doesn't always mean from outside North America.  It could be that a certain type of oak
tree from California is going nuts in Florida throwing acorns everywhere, sprouting anywhere you look,
and doing just as well as, if not better than, the native species in the area. This too is an invasive
species.  Think of invasive species more as a non-natives of the local ecosystem.

How bad is the problem?

    The short answer is bad.  There are over 380 invasive plant species in the southeastern United States
alone.  Among the non-tree species, an aggressive vine called Kudzou, is spreading fast and causing
major damage to the forests.   Invasive species aren't limited to plants.  There are insects, animals and
invertebrates as well.  One of the most noteworthy tragedies due to an invasive insect was loss of the
American Chestnut tree, which was almost entirely wiped out.  You can read more about that and
reasons to stick with native species here.  Sadly, this issue isn't limited to the southeastern United
States, or even the United States, this is a global problem and is changing forests and ecosystems
world wide.

How did this happen?

    Invasive species arrived several different ways.  Some were brought in for landscaping purposes and
have escaped into the wild.  Others were brought unintentionally in contaminated seeds, in packing
materials,  with livestock and in soils with other imported potted plants. 

What are some common characteristics of invasive species?

    Aggressive reproduction, rapid growth rate, mature early, adaptive, tolerant to changes and
disturbances, and having no natural enemies are a few characteristics most invasive species share.

Please note- these state lists include both state declared invasive species and species which are
declared invasive elsewhere but present in one or more counties within the state.

Kentucky Invasive Tree Species

Tree species listed by the Kentucky Exotic Pest Plant Council and their defined criteria for placement:

1.  Severe Threat
Exotic plant species which possess characteristics of invasive species and spread easily into native plant communities and
displace native vegetation; includes species which are or could become widespread in Kentucky.

Tree-of-heaven, Ailanthus altissima
Autumn olive, Elaeagnus umbellata
Princess tree, Paulownia tomentosa
Callery pear, Pyrus calleryana

2.  Significant Threat
Exotic plant species which possess some invasive characteristics, but have less impact on native plant communities; may have
the capacity to invade natural communities along disturbance corridors, or to spread from stands in disturbed sites into
undisturbed areas, but have fewer characteristics of invasive species than #1 rank.

Mimosa, Albizia julibrissin
White mulberry, Morus alba
White poplar, Populus alba

3.  Lesser Threat
Exotic plant species which seem to principally spread and remain in disturbed corridors, not readily invading natural areas; also
some agronomic weeds.
