Plants. These results suggest the presence of relative stable ecosystems and more ecological niches available in Kolonja areas. This approach is called in in-situ (on site) conservation. Sustainable capacity building. This deals with the current status and future research needs of various conservation strategies. It also includes bibliographic references and Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. The damage of plant genetic resources has made indispensable the development of new conservation strategies. © 2008-2021 ResearchGate GmbH. General considerations and scope Both in situ and ex situ actions can have potential ben-eﬁcial conservation impacts. This chapter deals with rationalizing germplasm collection management by individual genebanks. 8 . Ex situ conservation is a technique of conservation of biological diversity outside its natural habitats, targeting all levels of biodiversity such as genetic, species, and ecosystems [1 1. 6 In Situ and Ex Situ in Nature Conservation The terms in situ and ex situ are foundational in the discourse of the nature conservation movement.
