Eucalyptus crebra predominates and forms a distinct but discontinuous canopy (16-20 m high). The influences of individual trees on herbaceous understory were aggregated into stimulatory and competitive effects which were represented as indices. ... sapwood band is likely to be wider in fast growing trees but this simply reflects the water demands of a large healthy canopy. This equates to one plant/10m2 and allows for approximately 25% mortality across the planting.
