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
