MADISON, Wis. (AP) — A group of former Department of Natural Resources secretaries are urging Wisconsin Gov. Scott Walker and legislators to reject a proposal to divide the agency and spread its responsibilities across state government. Republican Rep. Adam Jarchow has proposed splitting the DNR into a new Department of Fish and Wildlife and a new Department of Environmental Protection. Three existing agencies would assume forestry, park and land acquisition duties. The former secretaries sent a letter Tuesday to Walker and legislators warning the move would confuse the public, create a coordination nightmare and a number of new supervisors that would need compensation, force environmental groups and outdoor clubs to deal with five agencies rather than one.
