Securing ex situ collections of Critically Endangered and Endangered Maples
Why action is needed
Over a quarter of the world’s maples are threatened with extinction in the wild. The recent Red List of Maples, published jointly by BGCI and Fauna & Flora International (FFI), in November 2009 identifies 54 maples as being in danger of extinction, out of a global total of 191.
Based on the information presented in the Red List report, urgent attention is required for the 26 maples considered to be at most risk of extinction - Critically Endangered (CR) or Endangered (E) - according to the IUCN Red List Categories and Criteria.
Some of these threatened maples are reduced to a handful of individuals in the wild and it would be a tragedy if such species are needlessly lost. It is clearly important that all CR and EN taxa are represented in well-managed ex situ collections. At the same time, habitat protection and restoration should be reviewed and mechanisms put in place for local people to be involved in and benefit from the in situ conservation and management of these globally important trees.
BGCI is now undertaking a comprehensive survey of ex situ collections of globally threatened maples building on information held within our PlantSearch Database. The survey will enable us to identify precisely which CR and EN maples are currently held in ex situ collections, what is known about their cultivation and what related conservation activities are currently taking place.
How you can help
We would be very grateful for your help with this survey. For each maple (Acer or Dipteronia) in your collection, we would ideally like to know:

Global Trees Campaign
Over 8000 tree species, 10% of the world’s total, are threatened with extinction. The Global Trees Campaign is addressing the problems with help from botanic gardens and BGCI.
