Estimates of Pre‐Settlement Insect Damage in Australian and North American Forests
1989
Morrow, P. A. | Fox, L. R.
Herbivores insect damage to broadleaved evergreen trees prior to widespread European disturbance of the environment was estimated from herbarium specimens collected in western North America and Australia. These data were used to determine whether the current pattern of higher levels of insect damage on Australian Eucalyptus trees than on comparable North American trees of similar habitat and leaf type is an inherent ecological characteristic of these systems or a consequence of recent European disturbance. The historical data confirm present day patterns. Several features of Eucalyptus and of Australian forests and woodlands may predispose them to higher levels of damage.
