• Relative species abundance

• Species percentage frequency

• Percentage cover

Percentage cover is useful when

• species are difficult to count (such as grass)

• species are easy to count (such as rabbits)

• quadrats are unable to be used

• species move around a lot

A value closer to _____ denotes good biodiversity (from the Simpson's Diversity Index)

• 1

• 100

• 10

• 0

Site 1 has a Simpon's Diversity Index of 0.81 and site 2 has 0.43. Choose the correct statement.

• Site 1 is more biodiverse than site 2

• Site 2 is more biodiverse than site 1

• You cannot compare the biodiversity of two different sites

• These numbers are qualitative and therefore more data is required to compare both sites
