conservation

Question 1

what is conservation

Answer 1

active management of habitats and species that live there
to maintain biodiversity and enable survival of endangered species
Involves human interaction

Question 2

explain conservation in situ
examples?

Answer 2

conserving species in their natural habitat

-marine conservation
-wildlife reserves = national parks

Question 3

how does conservation in situ achieve its goals to minimise human impacts and protect the natural environment

Answer 3

-legislation = laws stop hunting logging and clearing land

-establishing designated areas for conservation of habitats and species

Question 4

what are the advantages of in situ conservation

Answer 4

-conservation in natural environment
-permanent protection of natural and cultural heritage
-protection of biodiversity
-allows scientific research
-opportunity to improve and restore the ecological integrity (health) of an area

Question 5

what are the disadvantages of in situ conservation

Answer 5

-population may already have lost much of its genetic diversity
-fragmented habitats may mean the area may not be large enough for survival
-poachers and ecotourists will be attracted
-conditions that caused the habitat or species to be endangered may still be present

Question 6

what is conservation ex situ
examples?

Answer 6

-conserving an endangered species outside its normal habitat

-e.g zoos, botanic gardens, seed banks

Question 7

explain zoos, botanic gardens, seed banks

Answer 7

zoos= education programmes, scientific research, captive breeding programmes, reintroduction programmes

botanic gardens = plants actively managed

seed banks= store large number of seeds to conserve genetic diversity, large variety of species conserved as it’s cheaper and less space needed

Question 8

what are the advantages and disadvantages of ex situ conservation?

Answer 8

advantages;
-protects endangered species
-controls environmental conditions
-allows scientific research
-enables breeding rehabilitation
-preserves genetic diversity

disadvantages:
-expensive to maintain
-artificial environmental
-risk of disease transmission
-difficult to reintroduce species

Question 9

explain CITES

Answer 9

Convention of international trade in endangered species
aims:
-regulates / prevents trade in endangered species
-prohibits trade of wild plants
-ensures trade doesn’t endanger wild populations

Question 10

explain the aims of The Rio Convention of Biological Diversity

Answer 10

-sustainable use of organisms/ habitats / ecosystems

-share access to scientific knowledge

-promotes ex situ conservation methods eg seed banks

-raising profile of biodiversity with public / governments

Question 11

explain CCS and aims

Answer 11

Countryside Stewardship Scheme

-provides financial incentives for farmers and land owners to look after their environment by:
-conserving restoring wildlife habitats
-flood risk management
-encouraging educational access
-reducing water pollution from agriculture
