| dc.description |
Aerial and ground surveys to detect and evaluate forest insect and
disease conditions in North Dakota were made during June 1977 by
personnel from the U.S. Forest Service, Forest Insect and Disease
Management staff and the Rocky Mountain Forest and Range Experiment
Station.
A forest tent caterpillar outbreak in the Turtle Mountains was
estimated to cover 195,000 acres in this popular vacation area.
Siberian elm shelterbelts throughout the state were heavily defoliated
by the spring and fall cankerworms. Cottonwood trees along
the Missouri River near Bismarck were dying from a combination of
soil compaction and possible nitrogen poisoning in cattle feedlots.
Dutch elm disease was evident in six American elm trees near Lisbon. |
