Quadrat Method Flashcards
1
Q
What does the quadrat method involve?
A
- involves counting the number of individuals in small measured areas (quadrats)
- and then using these numbers to calculate the population size of the total area with the aid of the quadrant formula
2
Q
What is the formula for the total population when using the quadrant method?
A
[numbers in sample x size of whole habitat] ÷ size quadrat
3
Q
What is the purpose of using a quadrat?
A
- to enable comparable samples to be obtained from areas of consistent size and shape
4
Q
What is important to do when using quadrats?
A
- quadrats should be distributed at random
5
Q
Why is random sampling important?
A
- as the distribution of individuals may not be uniform throughout the area
- it is important to sample as many quadrats of the total area as possible
- to achieve a true reflection of the distribution
