Definition | A square or rectangular rigid frame of known area, often home-made, with the total area divided into sub-areas by a graticule made up of threads or wires connecting opposite sides of the quadrat spaced at equal intervals. It is placed on the substrate to mark a fixed area for sampling flora or fauna. The subdivision by the graticule increases the accuracy of coverage estimates. | ||
