Ex situ surveys

Ex situ surveys

Following publication of a taxonomically focused Red List, the Global Trees Campaign then undertakes a survey of ex situ collections to determine how well represented these species are in conservation collections. Information is collected from botanic garden, arboreta and other ex situ collection holders around the world.

Threatened species that are reported as lacking from ex situ collections, or represented only in a small number of collections are highlighted as priority species for conservation action and recommendations for their conservation are made.
