Answer 2

Control measures include appropriate equipment, clothing, footwear and means of communication.

Question 3

Question 4

What should be considered when carrying out sampling?

Answer 4

Consideration must be given to rare and vulnerable species and habitats that are protected by legislation

Question 5

What techniques can be used for sampling?

Answer 5

Point count
Transect
Remote detection

Question 6

What does a point count involve?

Answer 6

A point count involves the observer recording all individuals seen from a fixed point count location. This can be compared to other point count locations or with data from the same location gathered at other times.

Question 7

What techniques are used for plants or slow moving organisms?

Answer 7

Quadrats or transects of a suitable size.

Question 8

What techniques are used for mobile species?

Answer 8

Capture techniques

Question 9

How are elusive species sampled?

Answer 9

They can be sampled directly using camera traps or an indirect method
Scat sampling.
