Question
Which method can be used to measure population size and density in static creatures like plants, as well as very small and slow-moving species?
- Mark–Recapture Method
- Quadrats Method
- Sample Counting Method
- None of the above
Hint:
Quadrat method
The correct answer is: Quadrats Method
The quadrat method is used to sample sessile organisms, using a square within which all individuals are counted; extrapolation of the data to the entire habitat results in a population size estimate.
For immobile organisms such as plants or for very small and slow moving organisms, plots called quadrats may be used to determine population size and density.
