Recently a reader expressed dismay with efforts to remove Mute Swans from the lake where he lives. The exotic swans cause problems and death for native ducks and geese by preventing their nesting. I know of at least one instance where a Mute Swan killed an elderly man in his boat. Mute swans compete with native Trumpeter Swans being restored in the Great Lakes ecosystem where this native species was near extinction.
The reader told me that management to safeguard native ecosystem species is genocide of Mute swans. I stated that exotic Mute Swans of European origin are causing genocide of native wildlife populations. Wildlife biologists are working to prevent genocide of native species. He said he is also of European origin and killing exotic swans equates with killing people of European origin that settled North America.
I commented that social and political aspects for sustaining native ecosystems are often driven by emotions and/or short-term personal and economic interest instead of ecological health. We were present for a conservation fundraising banquet and the program was about to begin. We did not get to continue the conversation. I would like to know how he felt regarding efforts to kill and eliminate other exotics species that cause ecological and economic havoc in native community nature niches.
Environmental groups and governmental units are working to prevent Asian Carp from entering the Great Lakes where they will cause major economic, ecological and genocide problems for native species and will result in billions of dollars in environmental damage. Exotic species replace native plant and animal species and reduce biodiversity. Native species eliminated by exotic species is also genocide. Human efforts strive to protect native species evolved in ecosystems from genocide caused by exotic species. Native species help maintain the “Triple Bottom Line” of social, economic, and ecological integrity of the natural world that sustains our human culture.
We often choose beauty over ecological value. Purple Loosestrife is a beautiful exotic plant in wetlands that eliminates food and habitat for native species. Like the Mute Swan, its beauty makes it difficult for us to want it removed. The tall feathery seed headed grass called Phragmites (Common Reed) is replacing cattails and associated native wetland birds, mammals, insects, and plants. Removal of native species by Phragmites disrupts nutrient cycles and energy flow in ecosystems essential for sustaining breeding habitat or fish, birds, mammals, insects, and other life forms. Many eliminated native species have direct economic and social importance for human communities and businesses.
Many exotics lack the emotional appeal of Mute Swans and might fail to raise the genocide concern of the reader that spoke with me. Zebra Mussels cost Grand Rapids millions to prevent clogging of water intake pipes in Lake Michigan. I wonder if the reader is concerned about mussel genocide.
Exotics like Gypsy Moth, Quaga Mussels, Garlic Mustard, Emerald Ash Borer, Autumn Olive, Oriental Bittersweet, and swallow-wort are more than direct economic problems. They cause ecological disruptions and genocide in native plant and animal communities. Most exotic species arrive accidentally. We have quarantine inspectors working 24/7 to safe guard our livelihoods by preventing additional exotic species from disrupting native communities, agricultural timber, and food crops.
Exotic Garlic Mustard pulls are sponsored to prevent it from causing genocide to native wildflowers, associated insects, birds, and mammal that evolved locally over expansive time. How should we address difficult issues? “Triple Bottom Line” management addressing social-economic-ecological problems becomes a means for maintaining and sustaining a healthy society.
