| dc.description |
Dwarf mistletoes reduce tree height and diameter, and thereby cause a reduction
in volume production. We estimate that volume reduction in Montana is
about 33.2 MM cubic feet per year. Mistletoe effects are problems in some
areas because of the demands we have placed on the Forests for goods and
services. Much of their impact can be reduced to levels consistent with
resource management objectives through cultural practices. The resource
manager considers information on the stands, pest-caused losses, and
environmental and social considerations in deciding for or against cultural
control. |
