Global Survey of Ex situ Magnoliaceae Collections

The Red List of Magnoliaceae, published in 2007, called for action to ensure that the 89 taxa listed in the report as Critically Endangered or Endangered were conserved. The first stage of this action was to establish which of these threatened taxa are held in ex situ collections around the world by carrying out a global survey.

Published in 2008, this survey identified 2,274 Magnoliaceae records from 238 institutions in 47 countries. The survey identified that more than half of the Critically Endangered or Endangered taxa are currently not known to cultivation and therefore at great risk of extinction if threats that they are facing in the wild are not addressed.
