Practical 5: Workbook
These are questions to help guide you for your methods & results section
Part 1: Data Analysis in R
1. Abundance refers to the amount of a given species in an area. Which three invertebrates have the highest abundance in Centennial Park and Randwick Environment Park?
2. Based on your graph "Invertebrate Abundance" which park had the greater abundance?
3. Do the summary statistics for “Invertebrate Abundance” match what you see in the graph? Why might they not match?
4. Based on your graph "Invertebrate Richness" which park had the greater abundance?
5. Do the summary statistics for “Invertebrate Richness” match what you see in the graph?
6. Now that you know the Abundance and Richness, which park do you predict will have the higher Shannon H index?
7. After graphing and calculating the mean and standard error of the Shannon H index, which park has the higher biodiversity? Was your prediction from Q6 correct?
Part 2: Spatial Mapping in Google Earth Pro
1. Label the images below based on the geometry types we can create:
2. What were some of the dryer years for REP? Do we see the same in CP? Why?
3. Is Centennial Park classed as urban or recreational?
Is Randwick Environment Park classed as urban or recreational?
