Question
Discuss the advantages of in situ conservation of endangered species, using examples.
Markscheme
in situ conservation is carried out in nature reserves/natural habitats;
named example of a species that is being conserved in situ;
in situ conservation reduces possibility that habitat disappears and the whole community is lost / may prevent the total number of species that become endangered from increasing;
allows species to live in an environment for which they are adapted / they are able to fit into their normal food chains;
threatened species in a reserve may be monitored for further deterioration in numbers / remedial steps can be taken;
offspring acquire skills from parents/peers around them / offspring acquire natural behaviour;
reserves and protected areas in various parts of the world can share experience on how to manage them successfully;
nature reserves are popular sites for the public to visit maintaining awareness/education/scientific study;
reserves are places to return endangered individuals from breeding programmes as they provide realistic conditions for re-adaptation / OWTTE;
Examiners report
This question was very poorly answered by the majority of candidates with many confusing in situ with ex situ conservation. Those that did understand the concept could not really "discuss‟ the advantages of it clearly and were vague in their responses; thus few received more than 3 marks.
