Practical B4 - Use quadrats to investigate a habitat

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

Quadrat - random sampling


  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.
