Development of botanical garden is what type of conservation

Ex situ conservation means literally, "off-site conservation". It is the process of protecting an endangered species of plant or animal outside of its natural habitat; for eg, by removing part of the population from a threatened habitat and placing it in a new location, which may be a wild area or within the care of humans. While ex situ conservation comprises some of the oldest and best-known conservation methods, it also involves newer, sometimes controversial laboratory methods. Seed band is also an example of ex-situ conservation.
