2. Transport, transfer or introduce any other restricted invasive species identified or listed under sub. (2).

(b) Paragraph (a) does not apply to a person who transports, possesses, transfers or introduces a restricted invasive species identified or listed under sub. (2) if the department determines that the transportation, possession, transfer or introduction was incidental or unknowing, and was not due to the person's failure to take reasonable precautions.

Note: Paragraph (b) does not apply to preventive measures set out in s. NR 40.07.

(c) If authorized by a permit issued by the department under this chapter, a person may transport, possess, transfer or introduce a restricted invasive species for research, public display, or for other purposes specified by the department in the permit.

The offspring of pets possessed under this paragraph may not be transferred except as a gift.

(e) Paragraph (a) does not apply to a person who transports, possesses, transfers or introduces a terrestrial invertebrate or plant disease-causing microo rganism that is regulated under a quarantine imposed by D ATCP under s. 94.01, Stats., or a United States Department of Agriculture Animal and Plant Health Inspection Service quarantine area declared under 7 USC section 7714 or 7715 if any of the following apply:

This paragraph does not apply to terrestrial and aquatic vertebrates or fish species.

Note: New populations of restricted aquatic plant species may be reported to the appropriate department regional aquatic invasive species coordinator. Visit the DNR website (dnr.wi.gov) keywords "reporting invasives" to view a list of waterbodies with known invasives and reporting contacts.

Note: Section NR 20.08(1) prohibits the use of goldfish as bait and the possession of goldfish in any form or manner on any water of the state.

Note: Section NR 20.20(73) (c) 1. sets a bag limit of 0 for nonindigenous detrimental fish, but allows one such fish to be taken by hook and line if it is killed immediately and delivered immediately to a department service center or regional office. All nonindigenous fish species are declared under s.

(2).

Note: The effective date of the listing of a species under sub. (2) is the effective date of the rule that adds the species under sub. (2). Plants added to the restricted list under sub. (2) after 2009 are indicated by a note following the listing in sub. (2) stating the effective date of the listing. All plant listings in sub. (2) without an effective date note have been restricted since 2009.

(4) CONTROL REQUIREMENTS. Any person who grows a restricted plant at a nursery shall make a good faith effort to destroy it upon closure of the nursery.

Any person who owns, controls or manages land where a restricted plant species is present in the pioneering stage, in an area otherwise not infested with that species or where there is a high priority resource threatened by a restricted plant species is encouraged to control the restricted plant or contain it to the already infested sites, to reduce its population, and to foster an increase in desired species.
