NR 40.02 Definitions.
For purposes of this chapter:
“Algae" means a predominately photosynthetic eukaryotic organism ranging from unicellular to macroscopic forms, lacking true roots, stems, leaves, and embryos.
“Animal" means all vertebrate and invertebrate species, including but not limited to mammals, birds, reptiles, amphibians, fish, mollusks, arthropods, insects, and their eggs, larvae or young, but excluding humans.

“Category" means a grouping of species designated by administrative rule for which there are specific legal requirements or restrictions.
“Cave" means any naturally occurring void, cavity, recess or system of interconnected passageways beneath the surface of the earth or in a bluff, cliff or ledge, including pits and sinkholes, but does not include a rock shelter.
“Commercial cave or mine" means a cave or mine that has more than 1,000 visitors per year and charges a fee.
“Contain" or “containment" means to prevent spread beyond a designated boundary.
“Control" has the meaning given it in s. 23.22 (1) (a)
, Stats. In addition, “control" includes activities to eliminate or reduce the adverse effects of invasive species including decreasing or eradicating their population or limiting their introduction or spread, and includes destroying the aboveground, and when necessary, the belowground portions of a plant in a manner and at the proper time to prevent the development and distribution of viable seeds or other propagules. For plants that reproduce vegetatively, “control" includes the use of methods that contain or reduce the vegetative spread of the plant.
NR 40.02 Note
Section 23.22 (1) (a)
, Stats., states that “control" means to cut, remove, destroy, suppress, or prevent the introduction or spread of.

“Department" means the Wisconsin department of natural resources.
dumping or placing of any invasive species
water in a manner that prevents the establishment, introduction or spread
of the disposed species, or the consumption of the species as food.
“Eradicate" means to remove an entire population of an invasive species and all its propagules from an area of infestation.
“Established" means, for algae and cyanobacteria,
plants, terrestrial invertebrates and plant disease-causing microorganisms, aquatic invertebrates except crayfish, and terrestrial and aquatic vertebrates except fish,
present in an area as a self-sustaining population that is dispersed to the extent that eradication is either infeasible or will take a significant effort over a period of several years.
“Established nonnative fish species and established nonnative crayfish species" means alewife (Alosa pseudoharengus

“Feral" means existing in an untamed or wild, unconfined state, having returned to such a state from domestication.
“Genetically modified" refers to an organism whose genome, chromosomal or extrachromosomal, is modified permanently and heritably, using recombinant nucleic acid techniques, and includes the progeny of any genetically modified organism.
“Identified carrier of an invasive species" means any material identified in a department infestation control designation under s. 26.30 (7)
, Stats., a DATCP quarantine under s. 94.01
, Stats., or a United States Department of Agriculture Animal and Plant Health Inspection Service quarantine declaration under 7 USC section 7714
as potentially carrying an invasive species.
“Import" means to bring into Wisconsin or to arrange for another person to bring into Wisconsin.
“Incidental" means something is done inadvertently when performing an otherwise legal activity.
“Introduce" means to stock, plant, release or otherwise put an invasive species into the outdoor environment or use an invasive species in this state anywhere except within an indoor facility which is designed to physically contain the organism, including but not limited to a laboratory, greenhouse, growth chamber or fermenter.
“Invasive species" has the meaning given it in s. 23.22 (1) (c)
, Stats. In addition, “invasive species" means nonnative species including hybrids, cultivars, subspecific taxa, and genetically modified variants whose introduction causes or is likely to cause economic or environmental harm or harm to human health, and includes individual specimens, eggs, larvae, seeds, propagules, and any other viable life-stages of such species. For fish, “invasive species" includes all nonnative species.
NR 40.02 Note
Section 23.22 (1) (c)
, Stats., states that “invasive species" means nonindigenous species whose introduction causes or is likely to cause economic or environmental harm or harm to human health. The department does not consider dead specimens or organisms that are dead, not revivable, and no longer capable of living, growing, developing, reproducing, and functioning as “invasive species".
“Management action" means limiting the spread of established populations or abating harmful ecological, economic, social and public health impacts associated with invasive species introductions.
“Mine" means any artificial excavation, shaft, underground passageway, slope, tunnel or working from which ore or mineral is or was extracted, but does not include an open pit mine. However, caves or mines may be located adjacent to open pit mines.
