Service Notice

Recent taxonomic changes are not currently being reflected in Florabase, herbarium collections, or the census. Due to 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 May 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 Saturday, 2 May 2026 +08:00.
