Elephants were located from March 2000 to February
2002, two or three times a week. Locations
were aided by radio collars on one adult female
and an adult bull.Onsighting a Global Positioning
System (GPS) was used to record the position of
the group from a vehicle. Observations weremade
from the reserve’s extensive road and track network,
and off-road from a position that did not
influence the direction or rate of movement of the
elephants.
