A quadrat is a frame, traditionally square, used in ecology and geography to isolate a standard unit of area for study of the distribution of an item over a large area. Modern quadrats can for example be rectangular, circular, or irregular. The quadrat is suitable for sampling plants, slow-moving animals, and some aquatic organisms.
As nouns the difference between quadrant and quadrat. is that quadrant is quadrant (region of the cartesian plane) while quadrat is square.
