Answer 1

international union for conservation of nature

Question 2

what are the roles of the IUCN

Answer 2

• coordinate global data on biodiversity conservation
• increase the understanding of the importance of biodiversity
• develop nature based solutions to global challenges

Question 3

what does the IUCN do

Answer 3

categories species according to their vulnerability to extinction using the IUCN red list

Question 4

what are the IUCN red list categories

Answer 4

1) extinct
2) extinct in the wild
3) critically endangered
4) endangered
5) venerable
6) near threatened
7) least concern

Question 5

list the criteria used to select species for categorisation

Answer 5

1) if the species habitat is under threat
2) EDGE species
3) endemic species
4) keystone species
5) flagship species
6) degree of population dispersal

Question 5

list the criteria used to select species for categorisation

Answer 5

1) if the species habitat is under threat
2) EDGE species
3) endemic species
4) keystone species
5) flagship species
6) degree of population dispersal

Question 6

what is an EDGE species

Answer 6

an evolutionary distinct and globally endangered species= if there are few closely related species the existing species is often the last surviving genus such as the pygmy hippo- therefore it is important to preserve these species

Question 7

what is an endemic species

Answer 7

a species which isn’t found in any other area so if there are change to threats to its survival they are likely to die out

Question 8

what is a keystone species

Answer 8

a species which has an important ecological role in maintaining ecological structure of a community such as food provision or seed dispersal eg elephants

Question 9

what is a flagship species

Answer 9

a species which holds a high public profile there by raising support for its protection it will benefit conservation in general including species in the same habitat that are less likley to attract support eg polar bares

Question 10

why are habitats under threat used to categories select species

Answer 10

• their status may indicate the status of the rest of the community such as the decline of lemurs being used to predict the decline of many other species
