Quadrats and Transects

• Explain how a quadrat can be used to investigate the distribution of clover plants in two areas?


  Use a quatrat square to compare how common an organism is in two sample areas

  • put the square on the ground at a random point with the first sample area
  • count all organisms within the square
  • repeat steps 1 and 2 loads
  • do the mean
  • repeat 3 and 4 in second sample area
  • compare two means
• Suggest why you might use a transect when investigating the distribution of organisms

  You can use transects to help find out how organisms are distributed across an area

  • Mark out a line in the area you want to study
  • then collect date along the line by just counting all organisms that touch the line
