Table 1: Data Collection from stream

Use the Simpson’s Diversity Index to determine the effect of pollution on the level of biodiversity.  Remember the formula is:  Diversity Index = 1-Σ(n/N)^2

Record that information here: 

Pollution Level 

Simpson’s Diversity Index

Species Richness

None

   

Moderate

   

Severe

   

Use this information to produce a graph comparing the biodiversity indices of the stream with varying levels of pollution.   Which level of pollution would you invest time and resources into restoring, and why?
