Today in the staff conference Simon was asked the number of threatened plants that the RBGE is growing.
This is a dynamic figure as plants at the RBGE live and die and the IUCN assess more taxa for threatened status, but as of 23/01/2020 the number of threatened accessions alive in the living collection are given below.
| IUCN threat category | Num of living accessions |
| Extinct in the wild (EW) | 7 |
| Critically Endangered (CR) | 328 |
| Endangered (EN) | 855 |
| Vulnerable (VU) | 689 |
