| dc.description |
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. |
