Sampling Techniques
1. Identify as many as possible features of the environment around you. Eg. Sun, students
etc.
2. Measure one side of your quadrat __________cm
3. Area is worked out by multiplying the two lengths of the two sides.
4. What is the area of your quadrat? __________cm2
5. How many different organisms can you see in your quadrat? __________
6. Do you think there are any organisms present that are not visible? __________
7. Explain why or why not you think there are other organisms present

9. The squares below indicate percentage cover.
In the open box, show the percentage cover that the grass has in your square. What
percentage cover do you think the grass has? __________%
Explain whether you think that it is more accurate to count the number of organisms
present or to estimate the percentage cover as you did above? Explain your answer.
