Plants are sampled using a quadrat.A frame quadrat is a square frame that can be placed on the ground to enclose a small area.A point quadrat is a frame containing a horizontal bar through which ten equally spaced pins can be pushed.The type and number of species which touches each pin is then recorded.
A frame quadrat consists of a square frame divided into a grid of equal sections. The type and number of species within each section of the quadrat is recorded.The quadrat should be placed at random to study the presence and distribution of organisms in an area.
