The problem has <br /> now reached epidemic proportions and demands our urgent attention. To address this <br /> situation, the Minnesota Departments of Natural Resources and Agriculture, in <br /> cooperation with the University of Minnesota, are initiating a cooperative suppression <br /> project to be conducted on private and public lands in the state. Initially, this program <br /> will focus in Anoka County where the Oak Wilt problem is most serious, but is <br /> intended to quickly expand to all known Oak Wilt infested areas in the state. <br /> All oak species in Minnesota are susceptible to Oak Wilt, but species in the red oak <br /> group are most susceptible. Red oaks normally die in a few weeks, but white and bur <br /> oak survive infection for many years. A recent survey of the problem in the northern <br /> portion of the Metropolitan Region found 3,000 infection centers covering over 5,000 <br /> acres. Almost half of the infection centers and over two thirds of infected trees are in <br /> Anoka County. Most of these infections occurred in the past decade. <br /> MINNESOTA DEPARTMENT OF AGRICULTURE <br /> Plant Industry Division • 90 West Plato Boulevard • St.Paul,Minnesota 55107 <br /> AN EQUAL OPPORTUNITY EMPLOYER <br />
