Wildlife Forever is one group leading the charge against invasive species posing a threat to the fertile fields and fisheries of the United States. Wildlife Forever President and CEO Doug Grann recently reported back from the front lines of one such battleground: the Illinois River, beleaguered by an overabundance of Asian silver carp.

The battle for the Illinois River

The Midwest Association of Fish and Wildlife Agencies, representing 14 Midwestern state departments of natural resources, recently presented A silver carp jumps out of the Illinois River near Peoria, Ill.Wildlife Forever with its President’s Award. During the trip to Peoria, Ill., to accept the award, Grann took a time-out for wildlife to experience firsthand what conservationists are up against in the fight to stop the Asian silver carp in the Illinois River. His experiences were captured in a photo essay by Nathaniel Grann (some of the images are presented in this article, or the essay can be viewed in its entirety).

Asian carp are one of the few invasive species that are not only displacing native species – walleye and sauger among them – but they are dangerous as well. Known for their ability to leap many feet in the air, the sound of a boat engine can send whole schools airborne, sometimes landing in boats and posing a risk to passengers. During a short ride down the Illinois River, Grann said he saw airborne Asian carp nearly everywhere – 43 silver carp landed in his boat.

Asian carp are the most visible invasive species, but it is their destruction of habitat and the food chain that they have in common with all other invasive species. No matter how people like to enjoy the outdoors, invasive species are impacting camping, wildlife watching, hunting and fishing. It is the hope of Wildlife Forever that outdoor enthusiasts will take the time to educate themselves about the dangers of invasive species and the potential loss of America’s wildlife heritage.

Education is making a difference

Wildlife Forever has undertaken extensive work to stop the spread of invasive species. Much of the effort has focused on educating the hunting and fishing community on what they can and must do Doug Grann, CEO of Wildlife Forever, holds up a silver carp as Rob Hilsabeck, Illinois DNR, steers the shock boat down the Illinois River near Peoria, Ill. Silver carp have been known to grow to over 40 pounds in prime conditions. Unfortunately, the Illinois River just happens to host such conditions.during their time outdoors to avoid accidentally spreading non-native species.

Wildlife Forever’s Threat Campaign is now in its fourth year. During that time, the organization has used targeted messages in almost every media format available: television, print, billboards during fishing openers, the Internet, even free DVDs for local sportsmen’s clubs to show during their meetings. According to Grann, research reveals such efforts making great strides to turn the tide in the fight against invasive species.
