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

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.
