Invasive species – NISIC definition
(quote from www.invasivespeciesinfo.gov)
‘An "invasive species" is defined as a species that is
1) non-native (or alien) to the ecosystem under
consideration and
2) whose introduction causes or is likely to cause
economic or environmental harm or harm to human
health. (Executive Order 13112).
Invasive species can be plants, animals, and other
organisms (e.g., microbes). Human actions are the
primary means of invasive species introductions.’

The state quarantine officer may declare by regulation the weeds

designated as noxious which is already introduced and
established in the state to such an extent as to make its control
or eradication impracticable in the judgment of the state
quarantine officer.
