White pine blister rust (Cronartium ribicola J. C. Fisch) (WPBR) was discovered on Ribes L. in New York in 1906, although it was accidentially introduced from Europe on pine (Pinus L.) seedlings. The spread of this destructive fungus has changed the focus in North America. After decades of reduced planting because of the concern over the impact of WPRB, white pine (Pinus strobus L.) is now being restored in the lake states of Minnesota, Wiscconsin, and Michigan. Although the potential for growing white pine is high on many sites, the disapperances of a seed source because of logging and fires means that reestablishment of white pine to these areas will require active management. A series of planting have been established on three national forests in Minnesota and Michigan to evaluate various silviculture treatments intended to minimize the incidence of WPBR and to compare the performance of seedlings selected for disease resistance to nonselected planting stock.
