Extension programs attempt to control the cattail growth through various methods.
Normally, this involves control or eradication of 70 percent or less of the existing cattail in a wetland. Care is taken to assure that adequate winter cover for resident wildlife exists in the local area before these projects are undertaken. Since 1987, cattails have been controlled on 206 wetlands totalling 5,577 acres in North Dakota. Done in conjunction with other practices such as discing. Use only if there are other wetlands in the vicinity that also have adequate stands of cattail available for nesting birds and winter cover.
