Quadrats: estimate the population size to two areas
A single ecosystem can be divided into two parts by a fence, etc. resulting in the difference of number of organisms between the grazed and ungrazed.
Quadrating are based on square grids, formed by any materials such as woods and metals, to isolate a sample.
The square is like a sample to the area. To find the overall estimate, count the number of species inside each square (repeat it several times) and find the mean of the whole ecosystem.
The square size of quadrats can range from 0.25-1 metre.
