Expert Answer:

A quadrat is an ecological sampling unit that consists of a square frame of known area. It is used to study the composition of vegetation and animal life in a survey of the selected area. By sampling many quadrats, biologists can create data sets for statistical analysis. The advent of the quadrat was a key development in the professionalization of ecology. The most frequently used size is 1 metre squared. A major quadrat
is usually 10 meters square. The purpose of using a quadrat is to enable comparable samples to be obtained from areas of consistent size and shape.
