Abstract: Strong winds and shallow soils are the critical factors in the development of forests on the gravel plains of Canterbury. Studies of rooting systems in trees at Eyrewell Forest show that all roots are superficial and that, with employment of orthodox silvicultural systems, no degree of stand stability is likely to be achieved. Interlocking of root systems through development of a group structure in the stands does, however, offer some promise of greater wind-firmness
