Extensive Definition

A quadrat is a measured and marked rectangle, often a square, used in ecology to isolate a sample area for the purpose of measuring the abundance of different species within that 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.
