The Vancouver Island marmot (Marmota vancouverensis) is a small rodent that is only found on Vancouver Island and is listed as critically endangered. Captive breeding and release programs for this species began in 1997 to attempt to restore population numbers on the island. The graph shows the causes of death of the marmots born in the wild and of those marmots released after being born and reared in captivity.
Distinguish between ex situ and in situ conservation of endangered species.
[1]
ex situ is in artificial environment, in situ is in natural environment ✔
Accept examples as long as it is clear one is natural and one artificial
Many candidates were able to achieve the mark distinguishing between in situ and ex situ. It should also be mentioned more students appear to be comfortable with questions that ask them to “compare,” “contrast” and “distinguish,” and this may be due to comments in previous subject reports. The most common mistakes had students reversing the two concepts and focusing on etymologies can help here.
