Ecological Methods

Quantitative sampling is used to estimate seaweed abundance and distribution. (And sometimes to estimate dispersal patterns!)  Some people quantify seaweeds destructively by collecting them. As a class studying in a biological preserve, we prefer to patiently count individual seaweeds in their natural setting or to estimate their per cent cover on the rocks. Choose your method after you:

  • Define your research question
  • Collect preliminary data on site and local seaweeds
  • Decide how to analyze final data
  • Determine how to randomize and replicate your sampling
