Conservation ranking in action
In this activity, students work in small groups to rank a number of native reptiles and amphibians according to their conservation threat status or risk of extinction.
By the end of this activity, students should be able to:
better understand key conservation terms including ‘extinction’, ‘endangered’, ‘threats’ and ‘habitats
better understand the importance of a recognised ranking system
describe typical criteria used by scientists to rank animals according to their conservation threat status
understand more about human impacts on living things and the most common threats to reptiles and amphibians in New Zealand
appreciate why it is a difficult job to assign a conservation ranking to a species and that scientists may not always agree.
Conservation rankings
Dr Phil Bishop talks about our native frogs and some of the reasons they are so vulnerable to extinction. He describes the process of assigning a conservation ranking or threat status to a species.

Nature of Science
Assigning a conservation ranking to a species is an important process that requires input from a number of scientific experts. Rankings are not fixed and may change as new information becomes available.
