THE VALUE OF AERIAL INVENTORIES IN MANAGING MOOSE POPULATIONS
Extensive moose (Alces alces) aerial inventories were conducted in northern Ontario from January to March, 1976. The study: (1) looked at the efficiency and accuracy of a Piper PA 12 aircraft, (2) compared results between plots and transects among 9 periods of the winter, (3) tested a method of stra...
