Silver carp in the Illinois River jump in reaction to electrofishing. Credit: U.S. Fish & Wildlife Service The Illinois Department of Natural Resources has detected invasive carp in the Illinois River only 80 miles from Lake Michigan. That’s the closest the fish are known to have gotten to the Great Lakes, and hundreds were detected. Officials from the department also suspect there could be spawning grounds closer to the Great Lake and are monitoring the area further. They say floods and water t

LANSING -- The eastern massasauga rattlesnake is the only native venomous snake in Michigan -- but the state Department of Natural Resources says it has not killed anybody here in over a century.

Fisheries get one-time funding for whitefish restoration (opens the original)
Read excerpt
MARQUETTE -- The Department of Natural Resources Fisheries Division has received one-time funding of $350,000 for whitefish recovery. The ailing species has undergone a rapid population decline in recent years and for the first time, recovery efforts have landed a specific line in the state budget. But officials said while the money will help rescue some of the most vulnerable lake whitefish populations, it's not enough to address the systemic ecosystem issues causing the decline.
