Quadrats are very useful tools as they focus your attention on a small section of the environment, allowing you to see more detail… a bit like binoculars. Quadrats are useful tools to subsample a large area to get a representative picture of number of different species found on the seashore (biodiversity) and how many there are in a measured area (abundance). To find out more about quadrats, and their use by scientists, see Science Learning Hub: Quadrat.
You can easily make your own 1 metre square quadrat to survey the seashore community. A 4-metre piece of string, with knots tied every meter works fine – or maybe 4 flax leaves tied together. Be creative with the materials you use! Cardboard, bamboo, plastic, wood can all be used to make a quadrat. If you have pipe and some bungee cord you can make a quadrat that is foldable and reusable (use our resource to help guide you, it can be found here). Science Learning Hub also has more detailed instructions here!
