WAUSAU, Wis. (WSAW) -- The DNR is teaming up with local law enforcement agencies to catch white birch poachers in the Northwoods.
Officers said harvesting these trees without a permit or on land that isn't yours, is illegal.
Thieves can earn hundreds of dollars harvesting the trees, all while damaging the environment.
The DNR said thieves are looking for the trees in parks, forests, and private land.
"Over the last couple of years, in the Northwoods and across all of northen Wisconsin, we've been seeing a few unscrupulous people out stealing the resources," said Conservation Warden Supervisor Dave Walz.
The DNR is also asking people to keep an eye out for any suspicious activity.
