From your individual BIODIVERSITY MONITORING FORM for each sample and the CORRECTION FACTOR DETERMINATION FORM, (Biodiversity Step 2), complete the following.

 

  • Compile the inworksheetation from each replicate onto the DATA COMPILATION FORM
  • Add together the number of individuals found in each species
  • Divide the number of individuals found in each species by the number of replicates
  • Multiply each of your averaged the number of individuals found in each species by your calculated CORRECTION FACTOR
  • Compute the estimated percentage of individuals within each species in 1.0 m3 of water.
  • Rank your percentages according from most dominant species to the least dominant species

    The following is an example of a correctly filled in DATA COMPILATION FORM:
