Special Study Areas 
Suffield - Jenner Area, Alberta 
This study area was selected as typical of the unirrigated short grass 
plains of southern Alberta. The area was laid out as a continuous transect, 
beginning at the town of Suffield and running due north thirty-three miles to Jenner. 
The southerly twenty-three miles passes through rangeland, grazed on the west, 
but ungrazed on the east. The northern portion of the transect is cultivated. 
Three runs were made in May to establish the breeding population, the 
results of which are given below. The U. S. Fish and Wildlife Service worked 
the area by air on May 13 and 26 for correlation with ground data of the same 
approximate dates. An intensive brood count was made on July 15 both by air 
and ground. * 
The area is typcial and will be retained as a permanent study area. Good 
counts of territorial pairs can be obtained up to the end of May after which time 
the emergent vegetation begins to interfere. Intensive brood counts can be made 
only on the west side of the road for the first twenty-three miles. The east side 
is controlled by the Canadian Defense Board and trespassing is forbidden. A 
July 15 brood count in this area has little significance since by that date most 
pintail and many mallard broods are flying and have departed. The brood count 
was made for correlation with the aerial coverage.
