Ex-situ conservation means the safeguarding of components of biological diversity outside their environmental area (Rands et al., 2010). It involves the safeguarding of flora and fauna out of their accepted habitation by cultivation and maintaining plants in botanical gardens. The approaches of ex-situ safeguarding also involve long term preservation of flora in seed bank, in-vitro maintenance, DNA storage, etc.
Distribution and Use (Ethnobotany and Trade) of Bergenia ciliata (Haw.) Sternb. in Nepal
Published in Mahendra Rai, Shandesh Bhattarai, Chistiane M. Feitosa, Ethnopharmacology of Wild Plants, 2021
As prescribed by the Forest Regulation 1995 and its third amendment 2005, the government royalty of rhizomes of Bergenia ciliata is NRs. 2 per kg (GoN 2005). Both ex situ and in situ conservation of the species are recommended; however, in situ conservation is extensively applied. Ex situ conservation as cultivation is recently introduced. For sustainable harvesting of this plant, the rhizomes are collected before flowering from the matured individuals; the collection was done by leaving immature rhizomes in soil (Khanal 2003). 10–15 cm long rhizomes should be left inside the soil while collecting (Shrestha and Shrestha 2004). The harvesting period is from September to March (Khanal 2003) and the harvestable amount is 70–80% of the mother stock (Bhattarai and Ghimire 2006). The place where Bergenia ciliata was collected should be divided into many blocks and a rotation system of the collection was done every year (Bhattarai and Ghimire 2006).

Ex situ conservation is the conservation of biological diversity outside their natural habitats in locations that imitate their natural habitats. This involves the conservation of genetic resources, as well as wild and cultivated species. The approach draws on a diverse array of techniques and facilities, including seed banks in vitro plant tissue and microbial culture collections, artificial propagation of plants, with possible reintroduction into the wild and botanic gardens (Maunder et al. 2004).

Agricultural expansion (45%), followed by deforestation (31%), fire (14%) and overgrazing (10%) were mentioned by THs to be the major threats to the MPs resources. Likewise, in Ethiopia, agricultural expansion is the main challenge in conserving MPs (Tefera and Kim 2019). Moreover, the THs established that the younger generations are unwilling to learn this traditional healing practice. Hence, a great deal of important information regarding MPs could be lost when THs and elders die without sharing knowledge with the younger generations. The THs recommended planting MPs, followed by soil and water conservation, provision of awareness and protection of nearby forests as suitable methods for conserving and protecting MPs. In addition, the study suggests that in situ and ex situ conservation, good agricultural practices, and sustainable harvesting solutions should be sufficiently considered for the sustainability of MPs resources.
