Biodiversity Step 4 / Data Compliation Form
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:
