Camp Ripley and Arden Hills Army Training Sites Invasive Plants Invasive species are alien species, not native to the ecosystem, whose introduction does or is likely to cause economic or environmental harm or harm to human health. Invasive species have contributed to 42 percent of endangered and threatened species declines. In the United States 100 million acres (an area approximately the size of California) suffer from invasive plant infestations, and the annual cost of invasive species due to their impacts and control is five percent of the world‟s economy (The Nature Conservancy 2009). Federal agencies have been asked (Executive Order 13112) to prevent the introduction of invasive species, control existing populations, monitor populations, conduct research on invasive species, and promote public education of invasive species (U.S. Department of Agriculture 2009). In response to this Executive Order, Environmental Office staff contracted with St. Cloud State University (SCSU) in 2002 to begin an assessment of invasive plant species on Camp Ripley and AHATS. Sixteen and seventeen invasive plant species are found at Camp Ripley and AHATS, respectively (Table 7). Table 7. Invasive plant species on Camp Ripley and Arden Hills Army Training (AHATS) Sites (Babski 2002).

The goal of this project is to establish a comprehensive long-term control management program with minimal 2009 Conservation Program Report Page 24
environmental damage to native communities. Following are the 2009 accomplishments and 2010 work plan submitted by Jorge Arriagada, Alan Einck, and Jamie Hanson, St. Cloud State University. Camp Ripley Common Tansy Chemical Herbicide Treatments During the 2009 growing season, a large scale treatment of common tansy (Tanacetum vulgare) (one of the three major invasive species) was performed. The integrated treatment consisted of burning the plot area followed by an herbicide application approximately two weeks later. The chemicals used for this treatment were Escort ® and 2,4-D in combination. The large scale prescribed burn and herbicide treatment was done according to recommendations from the two-year tansy experiment completed in the fall of 2008 (Final results of the project are soon to be published). Preliminary results of the experiment are shown in Figure 13. There was a large decrease in the percent cover of common tansy as well as an increase in native plant species (Figures 14 and 15). Figure 13. Preliminary results of the two-year common tansy experiment. The combination treatment showed the largest decrease in percent cover as compared to the other variables.
