Enter the total number of species and the total area into the calculator to determine the species richness.

## Species Richness Formula

The following formula is used to calculate a species richness.

SR = TS / A
• Where SR is the species richness
• TS is the total number of species
• A is the total area

To calculate species richness, divide the number of species by the total area.

## Species Richness Definition

A species richness, also known as species density, is a measure of the total number of species in a given area of land. Species richness is also considered a metric of species diversity.

## Species Richness Example

How to calculate a species richness?

1. First, measure the total number of species.

Count up all of the species found in a certain area.

2. Next, measure the area.

Measure and calculate the total area observed.

3. Finally, calculate the species richness.

Calculate the species richness using the formula above.
