The directions moved by rats on control and treatment sites were proportional with the directions available. On control sites, there were three rats that moved towards
North, three to East, five to South and zero to West, with no preference for direction moved (the association between the observed directions used and directions
expected was not significant : χ23 = 4.636; P = 0.2004).On treatment sites, there was one rat that moved towards the removal area and 10 rats that did not move towards
the removal area (1/5 rats in March and 0/6 rats in June),with no preference for direction moved (χ21 = 1.778; P =0.1824). Therefore, the direction of movements were
essentially random on both control and treatment sites.
