Flora census

The 2021 Census of the Queensland Flora provides a published list of all the known native and naturalised species of plants, algae, fungi and lichens in the state. Formerly naturalised and doubtfully-naturalised flora are included in the full data set but species only known to be cultivated in the state are not included.

Our flora now has 14,778 known native species across all groups. That’s nearly double the number listed in 1913 (7,781 species). More than 20 species new to science are discovered in Queensland each year.

The current list is generated from the Queensland Herbarium specimen label information database as of 20 December 2021. These records are primarily based on the Queensland Herbarium specimen collections representing 240 years of verified specimen data.

The taxonomy of a number of plant families is evolving. This particularly applies in Orchidaceae at the generic level. Queensland Herbarium staff are working towards a consensus regarding the application of scientific names to orchids where the views of researchers vary.

2021 data

The census data is available through the Open Data website and presented in one spreadsheet, which can be filtered on any of the columns for subsets of the data (e.g. NCA status, Origin status, Name).

More information on the classification of the data is available in the census introduction (PDF, 1.4 MB) .
