Quadrat

From Wikipedia, the free encyclopedia

A quadrat is an area in a particular forest with a certain amount of living species. In addition it helps to know how plants are growing in this field and it is often used for observing the natural behavior of animals.

A quadrat is a measured and marked square, used in field biology to isolate a sample area for the purpose of counting the population 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.
