Simpson Index

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
