3.1.2.3.4 Habitat Conservation: Creation

Question 1

Habitat area

Answer 1

• must be large enough to support viable populations and their inter-species relationships

Question 2

Which species need large habitats?

Answer 2

• species high up the food chain (tigers) as they have low population densities

Question 3

Which species benefit from small habitats?

Answer 3

• frogs and toads need ponds that are too small for predatory fish
• so they can breed successfully

Question 4

Habitat shape

Answer 4

• a combination of conditions at the edge habitat is needed

Question 5

Vegetation age structure

Answer 5

• similar conditions to an old woodland are needed
• selective felling to create suitable conditions for smaller plants
• provision of dead wood to provide habitats for species

Question 6

Biological corridors

Answer 6

• allows for mixing of gene pools which reduces inbreeding risk
• allows recolonisation from other areas if a species dies out

Question 7

Habitat design factors

Answer 7

• Habitat area
• Habitat shape
• Age structure
• Biological corridors
