North Dakota’s Aquatic Nuisance Species List

November, 2007

The North Dakota Game and Fish Department, with input and cooperation from other members of the joint Aquatic Invasive Species Committee, has created a statewide aquatic nuisance species (ND-ANS) list. The official list includes biota considered as a threat to the states’ waters as these ANS have caused known irreversible ecological and/or economical consequences elsewhere. The negative impacts ANS may have on native North Dakota biota are great given the following: 1) North Dakota’s climate and habitats are favorable to the nuisance species, 2) they have a high potential to establish viable populations in North Dakota waters, 3) the ANS are likely to spread within North Dakota waters if a pioneering population becomes established, and 4) there are existing populations close to North Dakota and in a few cases, listed ANS do occur in the state.

The ND-ANS list will be reviewed annually and adjustments will be made accordingly. This may include additions of federally prohibited species, deletion of species which are not relevant to North Dakota’s concerns, and placing species on the ND-ANS due to a change in that species status for establishment in North Dakota’s waters.

ND-ANS are classified for permitting purposes. The permitting system is based on the need to control movement into or within North Dakota and allows for traditional use of select aquatic species. See ANS Classification System and Associated Permitting for details of the permitting system.
