Answer:
Diversity of the community = 2.097
Explanation:
Given:
Number of pitch pines = 134
Number of douglas firs = 24
Number of red pines = 53
Find:
Diversity of the community
Computation:
Simpson's diversity index = N(N-1)/Σn(n-1)
Particular n n(n-1)
Pitch pine 134 17822
Douglas firs 24 552
Red pine 53 2756
Total N=211 21130
So,
D= [211(211-1)] / 21130
D = 2.097
Diversity of the community = 2.097
