The lodgepole pine type commonly occurs as an even-aged, singlestoried, and overstocked forest. Dwarf mistletoe is widespread throughout the type and causes growth and quality reduction, reduced seed production, and some direct mortality. The land manager has three alternatives where dwarf mistletoe occurs: (1) do nothing, (2) eradicate the stand, or (3) reduce the infestation to a tolerable level. The nature of the disease as an obligate parasite with a restricted potential for spread provides an excellent opportunity for effective control by removal of infected trees as an integral part of silvicultural management.
