Classification, biodiversity and conservation: outline question

Outline6 marksChallenge

The Misty Mountain Forest Frog (Rana monticola) is endemic to high-altitude forests of Southeast Asia. The table below shows its estimated population size from 2000 to 2020.

Year	Estimated population
2000	12,500
2005	8,200
2010	4,600
2015	2,100
2020	850

The decline is attributed to competition from the introduced African clawed frog (Xenopus laevis), climate change reducing rainfall, deforestation for agriculture, and hunting for traditional medicine. Outline the reasons why the Misty Mountain Forest Frog is at risk of extinction and the conservation strategies that could be used to protect it.

How this question is marked

6 marks, so the mark scheme is looking for about 6 separate creditworthy points. Making the same point twice in different words earns it once.

Outline means: Give the main points briefly. Less detail than describe, but every key step has to be there. One short line per step, in order. The marks are for coverage, not depth.
