The distribution, abundance and relationships with environmental variables of feral pig rooting were investigated in a mountain forest and woodland in south‐east Australia. Feral pig rooting occurred in 27 of 29, 1/km 2 grids and the observed feral pig density was I/km 2 . A significant correlation occurred between the frequencies of plots with pig rooting and plots with pig dung. The frequency of feral rooting was significantly correlated with altitude, and with the frequency of rocks, drainage lines, and vegetation type. The occurrence of pig rooting was accurately predicted in 13 km 2 by a power series function. A model of the dynamics of feral pig rooting during an eruptive fluctuation was formulated.
