Service Notice

The Western Australian Herbarium’s collections management system, WAHerb, and DBCA’s flora taxonomic names application, WACensus, have been set to read-only mode since 1 October 2025. Recent taxonomic changes are not currently being reflected in Florabase, herbarium collections, or the census. Due to the rapidly approaching holiday season and associated agency and facility soft closures, along with the substantial work involved in data mapping, cleaning, and verification, the migration to the new collection management software is not expected to occur before 1 March 2026, when a further update will be provided. Please reach out to us if you have any questions or concerns.

The notice period started at 9:45 am on Friday, 12 December 2025 +08:00 and will end at 12:00 pm on Monday, 2 March 2026 +08:00.

Management Notes (for the Swan NRM Region)

General Biology. Growth form. Shrub/Small tree. Reproduction. Seed. Dispersal. Water, bird, ants, soil movement, garden refuse. Vegetative regeneration strategy. Produces root suckers. Seedbank persistence. Long, 5+ years. Fire response. Fire stimulates mass germination of soil stored seed. Adult plants can resprout from root suckers following fire.

Notes. Mass germination also triggered by mechanical disturbance.

Additional information. Origin. Eastern Australia. History of use/introduction. Garden escape.

Suggested method of management and control. Hand pull seedlings. For mature plants apply 250 ml Access® in 15 L of diesel to basal 50 cm of trunk (basal bark), or drill and fill with 50% glyphosate. Older plants can be ringbarked. Monitor site for recruitment from seedbank. 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.
