Invasive species represent major environmental and economic costs to the State of North Dakota. By putting our native flora and fauna at risk, invasive species threaten to drastically alter our immediate surroundings in urban and rural areas.
Invasive species affecting trees already established in North Dakota, such as the Dutch elm disease fungus, have had a major destructive influence on natural and urban environments, costing North Dakota communities millions of dollars. Some invasive tree pest species that are not yet in North Dakota pose an additional serious threat to tree resources across the state.
Invasive species can be plants, animals, and other organisms (e.g., microbes). Human actions are the primary means of invasive species introductions.
