This paper reviews current knowledge of the distribution, biology and management of blackberry in Australia, and the floristics of native vegetation susceptible to invasion. It also outlines the threat blackberry poses to native flora and fauna, including threatened species, and describes ways of minimizing the impact on off-target species when using herbicide for blackberry control in close proximity to native vegetation.
The revegetation of sites after the control of blackberry is also discussed. The paper explains the need to regenerate bare areas resulting from blackberry control in native vegetation, to prevent reinvasion of blackberry seedlings and those of other weeds, and to provide cover for native fauna.
Based on the information collated, important areas for research identified were:
i. comparison of growth of blackberry and competitive native species under various conditions,
ii. examination of native seed banks under blackberry thickets in native vegetation,
iii. the use of fire to stimulate germination of competitive native species in the seed bank.
