An ecological survey is carried out to estimate the total population of sea campion (Silene uniflora) on a flat coastal plateau measuring 60 m by 150 m.
Describe a method using 0.5 m×0.5 m0.5\text{ m} \times 0.5\text{ m}0.5 m×0.5 m quadrats that could be used to estimate the total population of sea campion in this area.
