Ex-situ conservation dealing with the off-site conservation of the wild genetic resources/ genetic diversity in natural habitat. It includes the collection, preservation and maintenance of selected genetic resources from wild.
Ex-situ conservation of medicinal plants is a complementary action to conserve the genetic diversity, thereby reducing pressure on wild habitats and augmenting raw material availability. For many species of medicinal plants their wild population is on critical level and it is not suitable for dealing in-situ conservation action. It can be serve as field gene banks and also help to engaging the number of stakeholders in production and regeneration of medicinal plants.
