For a random quadrat sample, divide the area into squares, generate random coordinates to place at least 20% of 1m² quadrats, count organisms in each, and calculate the mean.
Per un campione casuale di quadrat, dividere l'area in quadrati, generare coordinate casuali per posizionare almeno il 20% di quadrati da 1 m², contare gli organismi in ogni quadrat e calcolare la media.
| Front | How is a random quadrat sample taken? |
|---|---|
| Back | - divide area into grid of 1m2 squares - use random number generator to generate co-ordinates - to place a number (enough to cover 20% of sample area) of 1m2 quadrats - count organism in each quadrat - calculate mean |
