It occurs in over one-third of the ponderosa pine acreage in the region. Douglas-fir dwarf mistletoe occurs in roughly one-half of the mixed conifer acreage in the region.
Other species of dwarf mistletoe have more limited distributions see table. Aerial shoots of dwarf mistletoe plants vary by species in size, color, and pattern of branching. For example, southwestern dwarf mistletoe of ponderosa pine are often bright orange and conspicuous, and those of Douglas-fir dwarf mistletoe are often small and inconspicuous.
Host branches and stems are often swollen at the site of dwarf mistletoe infections. The size and extent of brooms varies among dwarf mistletoes and their host.

Dwarf mistletoes have separate male and female plants. Seeds are produced annually on female plants.
These are explosively released typically 1 to 12 metersand stick to host material. Upon germination, dwarf mistletoes produce an endophytic system, a specialized rootlike structure that is in contact with the phloem and xylem of host trees, from which the parasite obtains nutrients and water.

Aerial shoots appear 3 to 5 or more years after infection; the period before shoots are visible is known as the latent period. Spread of dwarf mistletoe occurs both from tree to tree and within the crowns of individual trees. Infections tend to build up initially in the lower half of a crown and gradually spread upward. Lateral spread of dwarf mistletoe through single-storied stands averages about 0.
Spread is relatively rapid from infected overstory trees to nearby regeneration.
