Which of the following is not a method of ex situ conservation? [2022]
In vitro fertilisation
National parks
Micropropagation
Cryopreservation
(2)
National parks are the method of in-situ conservation (Conservation in natural habitat).
In-situ conservation refers to [2022]
protect and conserve the whole ecosystem
conserve only high risk species
conserve only endangered species
conserve only extinct species
(1)
When we conserve and protect the whole ecosystem, its biodiversity at all levels is protected - we save the entire forest to save the tiger. This approach is called in situ (on site) conservation. However, when there are situations where an animal or plant is endangered or threatened (organisms facing a very high risk of extinction in the wild in the near future) and needs urgent measures to save it from extinction, ex situ (off site) conservation is the desirable approach.
The Earth Summit held in Rio de Janeiro in 1992 was called [2019]
for immediate steps to discontinue use of CFCs that were damaging the ozone layer
to reduce emissions and global warming
for conservation of biodiversity and sustainable utilisation of its benefits
to assess threat posed to native species by invasive weed species

Keystone
All of the following are included in 'ex-situ conservation' except [2018]
wildlife safari parks
sacred groves
botanical gardens
seed banks
(2)
Sacred groves come under in-situ conservation and represent the pristine forest patches around places of worship which are held in high esteem by tribal communities. Cutting of trees and branches is prohibited due to religious reasons. Wildlife safari parks, botanical gardens and seed banks come under ex-situ conservation.
Which one of the following is related to ex-situ conservation of threatened animals and plants? [2017]
Biodiversity hotspots
Amazon rainforest
Himalayan region
Wildlife safari parks
(4)
Ex-situ conservation is conservation of selected rare or threatened animals and plants in places outside their natural homes. It includes offsite collections like botanical gardens, zoological parks, wildlife safari parks, gene banks, etc.
The region of biosphere reserve which is legally protected and where no human activity is allowed is known as [2017]
buffer zone
transition zone
restoration zone
core zone
(4)
Core zone or Natural zone area of a biosphere reserve is undisturbed and legally protected ecosystem. No human activity is allowed in this zone. Little human activity is allowed in the buffer zone whereas in transition zone, an active cooperation is present between reserve management and local people for activities like settlements, cropping, etc. Restoration region is degraded area which is selected for restoration to near natural form.
