Endemic Species Ratio Calculator

Calculate the ratio of endemic species in a given ecosystem compared to total species

Endemic Species Ratio

--

Calculation Formula

Ratio = (Number of Endemic Species / Total Number of Species) × 100%

Where:
Total Number of Species - The total number of species in the ecosystem
Endemic Species - Species that are found only in this specific region

Interpretation

Endemic Species Ratio Calculator Usage Guide

Learn how to use the calculator to assess biodiversity uniqueness

How to Use This Calculator

  1. Enter the total number of species found in your study region (e.g., a specific forest, island, or watershed).
  2. Enter the number of species that are endemic to this region (found only here and nowhere else).
  3. Select the type of region and conservation status to help contextualize your results.
  4. Click the "Calculate" button to determine the endemic species ratio.

Understanding the Results

The calculator provides two key outputs:

  • Endemic Species Ratio - A percentage indicating what proportion of the region's species are endemic.
  • Interpretation - Contextual analysis of what your ratio means based on conservation status and region type.

Applications

This calculator is useful for:

  • Conservation planning and prioritization
  • Biodiversity assessments
  • Scientific research in ecology
  • Environmental impact studies

Example Scenario

Suppose you're studying a remote island with 500 total species, of which 150 are endemic. The calculator would show a 30% endemic species ratio, indicating a highly unique biodiversity that would warrant significant conservation attention.
