BGCI’s recent gap analysis has identified 20 Angiosperm families and almost 7,000 threatened tree species that appear to be completely missing from botanic garden living collections.


Download the lists here, and let us know if you have any of these plants in your collections.

If any of these species do feature in your collections, please update your PlantSearch records.

If they don’t and you would be interested in discussing ways in which BGCI could provide support in order to get these into your collections, please get in touch.


Please help us to ensure these plant species are protected from extinction!
