Annual District Reports: Forest Insect and Disease Survey ... - NFIS

-6-
1.2.2 Detection Surveys:- Greater emphasis placed on general collections
of forest insects and diseases, particularly in permanent sampling
areas and plots established throughout the Region, was aided in the
northern sections by improved road systems and expanded aerial surveys.
The Rangers travelled approximately 143,600 miles by road and 275 miles
by boat. They also used about 165 hours of flying time of which 33
hours was provided by the Provincial Forestry branches of Manitoba and
Saskatchewan, and their assistance and cooperation in this respect is
gratefully acknowledged.
Aircraft travel is summarized by Province in Table 2, and
the areas covered are shown on the accompanying map.

1.2.3 Survey Sub-projects:- Some adjustments were again necessary
in the number and scope of Survey sub-projects owing to the staff shortage
and changes in project plans. Accordingly, "Foliage Production of
Tamarack Studies at Permanent Plots" and "Surveys for Spruce Stand
Openings" were discontinued entirely in all Districts; the number of
"Spruce Budworm Egg Population Sampling" plots was reduced from 96
in 1962 to 22 in 1963; "Boxelder Twig Borer Population Sampling" was
discontinued at 12 of the original plots; and "Larval Sampling of
the Fall Cankerworm" was continued in only 3 plots in the Southern
District of Saskatchewan. "Larch Sawfly Studies in Permanent Plots"
was continued, but "Cocoon Collecting for Parasite Recovery" (using
