| dc.description |
The mountain pine beetle infestation existing on the Crow Indian Reservation
(IR) since the early 1970's, and later developing principally in the western
portion of the Northern Cheyenne IR, continued into 1984. Survey results
indicate the infestation is still building on both Reservations. To help
develop beetle management strategies appropriate for stands in eastern Montana,
studies to demonstrate the effects of several partial-cut regimes have been
initiated. That project and currently held management philosophies for
mountain pine beetle in second-growth ponderosa pine are discussed. |
