Biodiversity (4.2.1) Flashcards
What are the advantages of in situ conservation?
Both the species and the habitat are conserved
Larger populations protected
Less disruptive for the organisms
Why would you use systematic sampling?
If there is a clear change in the physical conditions across the area being studied.
e.g.altitude, soil pH or light intensity
What are the methods of in-situ conservation?
Protected areas
National parks and wildlife reserves restrict development and farming
Control or prevent the introduction of certain species
For example, the grey squirrel
Promote particular species by protecting food sources or nesting sites
Legal Protection
What are some methods of ex-situ conservation?
Relocation
to a safer area
Breeding in captivity and reintroduction to the wild
Botanic gardens
for conservation, research and education
Seed banks
protect against disease or natural disatsers
What are the advantages and disadvantages of ex-situ conservation?
You can protect individual animals in a controlled environment and things like
predation and hunting can be managed more easily.
Only a small number of individuals can be cared for and it can be difficult and expensive to create the right environment.
Animals are more likely to be habituated to human contact and less likely to show natural behaviour. Many species can not breed successfully in captivity.
Rio Convention on Biological Diversity (CBD)
Aims to develop international strategies for the conservation of biodiversity.
Made it part of international law that conserving biodiversity is everyone’s responsibility.
Provides guidance to governments on how to conserve biodiversity.
Convention on International Trade in Endangered Species (CITES)
An agreement designed to increase international cooperation in regulating trade in wild animal and plant specimens.
Member countries outlaw the killing of endangered species.
Helps to conserve species by limiting trade through licensing.
Designed to raise awareness of threats to biodiversity through education.
The Countryside Stewardship Scheme (CSS)
Aims to conserve wildlife and biodiversity.
10-year agreements with landowners. Paid to follow management techniques.
