All of the following are included in 'ex-situ conservation' except

Sacred groves are patches of forested areas that are protected by local communities due to religious or cultural beliefs. In many cultures, these groves are believed to be the abode of spirits or deities and are, therefore,
treated with great reverence and respect. They are a method of in situ conservation, since the conservation of biodiversity occurs within the natural habitats. 
Ex situ conservation refers to the conservation of biological diversity outside their natural habitats, and it involves relocating a species from its original habitat to a protected area. It is achieved through various means, such as zoos, botanical gardens, seed banks and wildlife safari parks.
