Terrestrial Invasive Species

There is no Calumet County staff to work on the issues related to terrestrial invasive species. Additional information can be found on the WDNR website, http://dnr.wi.gov/invasives/, the websites for the Invasive Plant Association of Wisconsin (IPAW) at www.ipaw.org or the Midwest Invasive Plant Network (MIPN) at www.mipn.org.

Many invasive non-plant species are in or near Calumet County as well.  This list includes the gypsy month, emerald ash borer, mute swans and wild boar to name a few.  For additional current information on these and other non-aquatic invaders, visit the WDNR website, http://dnr.wi.gov/invasives/.

Funding from the Citizen-Based Monitoring Network paid for the mapping of wetland and terrestrial invasive plants in Calumet County.  The mapping targeted species that are still in the stage of possible control or eradication in this county.  Some of the invasive plants in the county, such as buckthorn, honeysuckle, Canada thistle, reed canary grass and garlic mustard, are already so common that mapping would not have been productive. 

There are many terrestrial invasive species in Calumet County that are not described below, including dame’s rocket, soapwort, yellow and white sweet clovers, ox-eye daisy, crown vetch, reed canary grass, Japanese barberry, Russian olive and autumn olive to name a few. Listed are some of the plants that are of the greatest concern for this county at this time.
