Gene banks, zoos, nurseries, botanical gardens, aquaria, etc. contribute to ex situ conservation of wild plant and animal species of foreign origin by ensuring long-term conservation of species outside their natural habitat (ex situ).

For cultivated plant species and varieties and for domesticated animal breeds, ex situ conservation centres make it possible to maintain a large gene pool to ensure future viability and improvement of qualities. Based on scientific knowledge, ex situ conservation centres will be encouraged to preserve species, varieties and domesticated animal breeds in a way that ensures their conservation. Due to the wide diversity of collections, there is a need to strengthen coordination among ex situ conservation centres, for example by sharing information and facilitating access to foreign data for countries of origin, to ensure long-term conservation and facilitate access to information and collections.
