(3e)
A quadrat (square frame, usually 1m²) is placed randomly on the ground in the study area. All organisms within the quadrat are counted and recorded. This is repeated at several locations. The data collected is used to estimate population size, frequency, and distribution of organisms in the habitat. Results from multiple quadrats are averaged to represent the entire study area.
