Use quadrats to investigate the abundance of plants and/or animals in a habitat.

Quadrat - random sampling

Procedure

1. Divide the area to be sampled into a grid using measuring tapes placed at right angles to each other.
2. Use random numbers to generate coordinates within the grid on which to place the quadrats.
3. Place a quadrat at each coordinate.
4. Count the numbers/estimate percentage cover of each species in each quadrat.
5. Use a key to identify each species.
6. Record results in a table.
7. Calculate the average of each species.
