General Biology. Growth form. Shrub. Reproduction. Seed, stem layering, suckers. Dispersal. Birds, mammals, water, foxes. Time to first flowering. 2 years. Vegetative regeneration strategy. Resprouts, produces root suckers, stem layering. Seedbank persistence. Soil, short, days-1 year. Fire response. Can regenerate from roots following fire, cool fire will result in rapid regrowth from crown, hot fire will kill crown, but rapid regrowth will occur from root suckers.
Notes. In 2004/2005 herbarium collections of blackberry were made across the state as part of a NRM project to determine the overall distribution and incidence of weedy blackberry taxa. It identified WA has several weedy Rubus species, with no native Rubus species. For further information on identification refer to Barker and Barker (2005) Blackberry: an identification tool to introduced & native Rubus in Australia [CD-ROM] or CSIRO (2005) Field guide for the identification of WA blackberry. R. anglocandicans was previously misidentified as R. discolor in Western Australia and as R. procerus in south-eastern Australia. It is the most common, widespread and dominant weedy blackberry in WA. Occurs from Perth to Albany. Forms dense, impenetrable thickets that crowd out native plants and increase fire risk. Susceptible to the rust Phragmidium violaceum. At one site near Perth it co-occurs with R. laudatus and R. ulmifoloius, indicating the ability of all three species to colonise the same habitat.
Additional information. Origin. Central/eastern Europe. History of use/introduction. Garden escape. Similar exotic species. R. ulmifolius, R. laudatus.
Suggested method of management and control. Spray with metsulfuron methyl 1 g/10 L + the wetting agent Endose® at 30 ml/10 L, in summer-autumn. Will require follow up for a number of years. For small infestations or in sensitive areas hand pull small plants or seedlings. For larger plants cut and paint with 20-50% glyphosate or slash canes. Spray regrowth at 50cm with metsulfuron methyl 1 g/10 L + the wetting agent Endose® at 30 ml/10 L, in summer-autumn. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
