Service Notice

The Western Australian Herbarium’s collections management system and census were set to read-only mode on 1 October 2025. Taxonomic updates published since this time are not being reflected in Florabase, herbarium collections, or Western Australia’s taxonomic names census (Nomos). Conservation listings displayed on Florabase may also be out of date. Please refer to DBCA’s Threatened species and communities webpage for the most recent Threatened and Priority Flora List, noting that recent taxonomic updates are similarly not included. Our database migration is moving to a staging phase. We thank you for your patience as we ensure the integrity of our biodiversity data, develop new workflows, and train staff to use the new systems. Please reach out to us if you have any questions or concerns.

The notice period started at 12:00 pm on Wednesday, 1 October 2025 +08:00 and will end at 12:00 pm on Friday, 1 January 2027 +08:00.

Management Notes (for the Swan NRM Region)

General Biology. Growth form. Grass. Life form. Perennial, caespitose. Reproduction. Seed. Dispersal. Wind, ants. Photosynthetic Pathway. C3.

Notes. Also naturalised in South Australia. Most common in disturbed or open sites, including remnant grassy woodlands. Often occurs in much higher densities than native grasses, resulting in reduction or complete loss of the inter-tussock spaces.

Additional information. Origin. South Africa.

Suggested method of management and control. Cut out small plants, avoiding excess soil disturbance. Spray with grass selective herbicide or glyphosate when actively growing. For large infestations slash/brushcut in mid spring/early summer before seed matures to reduce seed set. 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.
