Quadrat sampling involves counting all individuals within a known area (or volume). Since density (D) and population size (N) are related, as N = D x area, we can estimate the density for the sample and from this compute the total population.
What is an example of quadrat sampling?
Sampling of plants or slowly moving animals (such as snails) can be done using a sampling square called a quadrat. ... For example, to count plants growing on a school field, one could use a quadrat with sides 0.5 or 1 metre in length. Choice of quadrat size depends to a large extent on the type of survey being conducted.

How do you calculate species density using a quadrat?
Calculate the population density using the number of organisms per quadrat and the quadrat size. For example, 10 organisms per 1 square metre quadrat would give a population density of 10 organisms/square meter. Calculate the total population by multiplying population density by the total sample area size.
