Ex Situ Conservation
Ex situ conservation is the conservation and maintenance of samples of living organisms outside their natural habitat, in the form of whole plants, seed, pollen, vegetative propagules, tissue or cell cultures.
Ex situ conservation has several purposes:
These ex situ collections of living organisms (living collections, seed banks, pollen, vegetative propagules, tissue or cell cultures) need to be managed according to strict scientific and horticultural standards to maximise their value for conservation purposes. Thus they need to be correctly identified, documented and managed and an efficient information management system put in place. Integrated conservation management can also ensure that ex situ collections can support in situ conservation, through habitat restoration and species recovery.

Overviews of the ex situ collections in botanic gardens.
The BGCI PlantSearch Database provides a central source of information about plants held in botanic gardens.
Specific Examples and Case studies
Many of our journal articles discuss the problems and progress that botanic gardens have made towards the ex situ conservation of certain plant taxa. Please follow the links to the articles in the green box to the right of this text, or browse our journal archive.
You can also download a presentation of the challenges in revising collection policy faced by Montreal Botanical Garden, presented by Michel Labrecque at the 2nd World Botanic Garden Congress, Barcelona, Spain, in April 2004.

You can also see a review of a recent book "Ex situ plant conservation supporting species survival in the wild" edited by by Edward O. Guerrant Jr., Kayri Havens and Mike Maunder, 2004.
Seed banks are essential for ex situ conservation, and many botanic gardens contribute and collect seeds for storage. However, setting up a bank, collecting and maintaining viable and representative stocks is very challenging.
Botanic Gardens Community Toolbar
BGCI has created a free community toolbar for people in botanic gardens around the world. You can add it easily to your internet browser. The toolbar gives you instant access to all our searches, gives the latest news on botanic gardens and there's even a chat facility for contacting colleagues.
