Simpson Diversity Index Calculator
The Simpson Diversity Index Calculator computes Simpson's dominance (D) and the widely used Gini-Simpson diversity index (1 - D) using the standard finite-sample formula from ecology. It quantifies evenness and dominance reliably for biodiversity assessment.
About the Tool
Input abundances to instantly get D, 1-D, richness, and interpretation. Ideal for agriculture, ecology, and soil/plant studies.
Importance of the Simpson Index
Highlights dominance/evenness in communities—key for resilient agroecosystems, pest control, and sustainable farming practices.
User Guidelines
- Enter comma-separated counts or name:count format.
- Example: 450,120,80,30 or Rice:450, Wheat:120
- Click Calculate for results.
- Higher 1-D = greater diversity/evenness (0–1).
When and Why to Use It
Use for comparing systems or evaluating impacts. Why? Standard, interpretable metric focused on evenness and dominance.
Purpose
