Description: Larch dwarf mistletoe (Arceuthobium laricis (Piper) St. John) is a common and damaging parasite of western larch (Larix occidentalis Nutt.) in the Pacific Northwest and southern British Columbia. Larch dwarf mistletoe occurs commonly throughout the range of western larch in British Columbia, northern and central Idaho, western Montana and east of the Cascades in Washington and Oregon (figure 1). Surveys of national forests in this "Inland Empire" indicated that about 35% of the western larch forests in this region are infested and that nearly 50% of the larch forests in eastern Oregon and Washington are infested with larch dwarf mistletoe. Because of its widespread occurrence, its high incidence in larch forests, and the impacts associated with high levels of infection, larch dwarf mistletoe is considered to be the most important disease of western larch.

Keywords: Disease, decline, mortality.
