Although the exact experimental design will determine where and how many samples are taken, the procedure always involves measuring plant characters of only those plants inside the quadrat. Quadrat sampling usually attempts to define plant community characteristics for an area much larger than the actual area sampled.

At the end of each of 20 successive weeks, the total number of individuals of Chthamalus present in each area was counted, using EcoBeaker's placed-quadrat sampling technique. The experiment was then repeated three times in order to provide replication.

Quadrat sampling for sessile organisms ... Recording data is straight-forward for quadrat sampling. Write down the counts or area covered for each quadrat, along with the size of the quadrat, habitat description (if there is more than one), and position of the quadrat in the sampling scheme (coordinate numbers, for example).
