To solve this problem, we need to identify which option is not included in 'Ex-situ conservation'. Let's analyze each option:$\newline \bullet$Botanical gardens:$\newline$ - Botanical gardens are places where plants are grown for scientific study and conservation.$\newline$ - They are a form of ex-situ conservation as they involve maintaining plant species outside their natural habitats.$\newline \bullet$Sacred groves:$\newline$ - Sacred groves are tracts of forest that are conserved in the name of religion or tradition.$\newline$ - They are a form of in-situ conservation as they preserve species within their natural habitats.$\newline \bullet$Wildlife safari parks:$\newline$ - Wildlife safari parks are areas where animals are kept in large enclosures for conservation and tourism.$\newline$ - They are a form of ex-situ conservation as they involve maintaining animal species outside their natural habitats.$\newline \bullet$Seed banks:$\newline$ - Seed banks store seeds as a source for planting in case seed reserves elsewhere are destroyed.$\newline$ - They are a form of ex-situ conservation as they involve preserving genetic material outside the natural environment.$\newline$Based on the analysis, the correct option is:$\newline$Option 2: Sacred groves, as they are not a part of ex-situ conservation.
