Diversity Index Calculator
The Diversity Index Calculator measures biodiversity using scientifically validated indices: Simpson's (Gini-Simpson: 1 - ∑p_i²) and Shannon (H' = -∑p_i ln(p_i)). Ideal for ecology, agriculture, and environmental studies, it quantifies species richness and evenness reliably.
About the Tool
Input species counts to instantly compute Simpson's and Shannon indices. Perfect for agronomists, researchers, and farmers assessing crop, soil, or ecosystem diversity.
Importance of Diversity Indices
Biodiversity supports resilient, productive agricultural systems. These indices reveal balance vs. dominance, guiding sustainable practices like intercropping and conservation.
User Guidelines
- Enter: species: count pairs or just counts (comma-separated).
- Example: 450,120,80,30 or Rice:450, Wheat:120
- Click Calculate for results and interpretation.
- Higher values = greater diversity/evenness.
When and Why to Use It
Use for comparing fields, evaluating practices, or research. Why? Standard, accurate metrics for evidence-based decisions in farming and ecology.
Purpose
To democratize biodiversity measurement for sustainable agriculture. Featured by Agri Care Hub. More at Diversity Index Calculator on Wikipedia.
These tools draw from decades of ecological research. Simpson focuses on evenness/dominance; Shannon on rare species and uncertainty. In delta agriculture, they help track resilience amid floods and intensification.
