Botanic gardens house over 105,000 plant species  (30% of all land plants), but keeping them alive requires significant effort, resources, and data management.

Using data from living collections, researchers created a tool to analyse  2.2 million records from 100 years of operations in 50 botanic gardens worldwide.

Researchers found that botanic gardens have stopped growing in size and plant diversity due to limited resources and restrictions around acquiring wild specimens.

Researchers stress the need for global collaboration to address climate change and protect species, but fear botanic gardens are losing the battle to prioritise biodiversity loss.
