# Species Richness Index Calculator

Margalef richness index calculator to find Margalef diversity index. Species richness index denoted by 'S' is the simplest measure of biodiversity. It is a count of the number of different species in a given area or community. However, complete inventories of all species present in practical applications is an unattainable goal. The species richness index calculator uses the margalef formula for the calculation of margalef richness index in biodiversity.

#### Formula:

Margalef Richness Index in Biodiversity = (S - 1) / Log (n)
**Where,**
S = Total Number of Species
n = Total Number of Individuals in the Sample
### Example:

Find the margalef richness index in biodiversity for total number of 25 species and 12 individuals in the sample.

#### Solution:

Species Richness Margalef Diversity Index = (25 - 1) / log(12)

= 9.6583
