The collection register is open to both private and public collections. SHBG is committed to preserving biodiversity, particularly through collections held both privately and in public gardens.

As nurseries limit stock available as economics becomes stronger than botanical interest, collections are forming an increasing importance in the world of biodiversity.

Housing development is one of the greatest threats to private plant collections. By registering your collection SHBG can lobby developers and local government to protect collections, either in or ex-situ.
