We can go for
1) ex-situ conservation.
In ex situ conservation the threatened species of plants and animals are taken out of their habitats and are kept in special settings such as zoological parks, botanical gardens and wildlife parks.
Advantages of ex situ conservation are:
(i) Offsite collection can be used to restock depleted population, reintroduce species in the wild and restore degraded habitats.
(ii) useful in maintaining a large number of genotypes in small area, rapid multiplication of even endangered species, through tissue culture, etc.
The gametes of endangered species can be preserved by methods such as cryopreservation and can be fertilised in vitro followed by propagation through tissue culture methods. Similarly, seeds can be preserved in seed banks. This can also be very helpful to prevent the loss of biodiversity.
