A ground-based survey of 400 Eucalyptus tereticornis trees revealed a relationship between the incidence of hollows and spacing between neighbouring trees. When the distance between trees is 0.3 times total tree height, it is more likely for a tree to suffer branch breakage and subsequent hollow formation. This finding offers management opportunities for regrowth forests and restoration plantings.
A ground-based survey of 400 Eucalyptus tereticornis trees examined the incidence of visible hollows suitable for hollow-dependent fauna. As well as the expected relationship with stem diameter, data analysis revealed a relationship between the incidence of hollows (with entrance diameter >= 10 cm) and spacing between neighbouring trees. When the distance between trees is equivalent to 0.3 times total tree height, a tree is more likely to suffer branch breakage and subsequent hollow formation. This influence of spacing, likely due to branches clashing during storms, appears to contribute a twofold difference in the incidence of hollows. This offers opportunities for the management of regrowth forests and restoration plantings, especially where one of the objectives is to encourage the formation of hollows.
