In Situ & Ex Situ Conservation

Question 1

What are the two types of conservation?

Answer 1

in situ & ex situ

Question 2

What is in situ?

Answer 2

it is on the site conservation of species in their natural habitat e.g. wild life reserves and marine conservation zones

keeping them on their natural habitat in a
natural enviroment e.g. wildlife reserves and marine reserves

Question 3

What is ex situ?

Answer 3

it is the off site conservation of species in a location outside their natural habitat

take species away from its habitat and conserve it another location
e.g. seed banks, botanic gardens, zoo, etc

Question 4

What is insitu conservation?

Answer 4

e.g. wildlife reserve and marine conservation zones

habitat and species are conserved/saved at the same time
control population of invasive (non-native species) e.g. rats in New Zealand
legal protection e.g. trade in ivory (elephant horns)
supplementary feeding / resting boxes - helps species

limitations -
hunting is hard to control
habitat can be destroyed - unavoidable if habitat cant be saved e.g. climate change

Question 5

What is ex situ conservation?

Answer 5

e.g. seed banks, botanic gardens, and zoos

health of individuals can be monitored
reduce mortality rate of young e.g. eggs can be artificially incubated
protection from hunting
reduce interspecific intraspecific competition
mates can be selected to maintain genetic biodiversity

limitations -
few breeding individuals - genetic biodiversity decreases
some species dont breed well in captivity e.g. panda
expensive and long term
