HOLYOKE, Minn. – Mike Dahl kicked leaves from the edge of the Little Net River in Nemadji State Forest, his workplace for 39 years.
A nearby ATV trail had washed out in a summer downpour, muddying the stream and threatening its brook trout. With the next big rain, still more soil would surge from the heavily used trail into the water.
"It's like a lava flow," said Dahl, a retired state forester who still lives on Nemadji's northern fringe, 32 miles from Duluth. "DNR doesn't always use its own best management practices to help protect stream corridors."
The Minnesota Department of Natural Resources is in the midst of a multimillion-dollar ATV trail building boom to accommodate the tens of thousands of new off-road machines sold to Minnesotans in recent years. Advocates vow to lace the North Woods with a network of forest pathways from the Iron Range to International Falls and the North Shore.
All this expansion comes with goals of getting more Minnesotans outdoors, pumping money into local economies and creating safer riding experiences. To intensify its ATV trail planning, including building two $1 million bridges, the DNR asked the Legislature this year for $250,000.
The spending spree is out of control, environmental advocates say, claiming the state's latticework of ATV trails destroys fish and wildlife habitat, crowds out hunters, birders and other outdoor enthusiasts, burdens already too-thin ranks of DNR conservation officers and costs too much to maintain.
"There's such a proliferation of trails now, you can't believe it," said Bob Djupstrom, a former DNR executive who has hunted grouse, deer and bear in Nemadji for decades. "This used to be a really, really wild forest. Now it's basically a big motorized trail system."
ATVs border to border
Minnesota ATV registrations grew to 323,956 machines last year, a 36% increase from 15 years ago, and associated fees and gas taxes have juiced the DNR's ATV Fund to $8.8 million — a 417% increase since 2000.
