Determining Diversity
In this activity, students use the Shannon-Wiener Function to determine diversity indices for 8 "study plots" and make "evenness graphs" using each plot's data. Students then respond to prompts about differences between plots.

Step 3: Use the plots in the document below to complete your Google Sheet. For each plot, determine the number of individuals for each species and enter the values in the corresponding cells for each species. When entering values, be sure that the identifying letter for the study plots and spreadsheet "tables" match.
