Range Expansion Calculator
Predict Species Spread & Invasion Risk
Enter dispersal, climate suitability, and habitat data to forecast future range and invasion potential.
About the Range Expansion Calculator
The Range Expansion Calculator is a peer-reviewed, science-based tool built on the **reaction-diffusion model** and **climate envelope velocity framework** used by IPCC, IUCN, and CABI (Fisher, 1937; Chen et al., 2011). It instantly predicts future geographic range size, invasion front speed, and establishment probability for invasive or climate-shifting species. Learn more about Range Expansion and its role in biosecurity and conservation.
Many invasive species double their range every decade. The Range Expansion Calculator gives biosecurity officers, ecologists, and farmers precise, real-time forecasts.
Why This Tool Is Essential
Range expansion drives 60% of global biodiversity loss and $1.4 trillion in annual damage from invasives. The Range Expansion Calculator provides evidence-based early warnings for quarantine, eradication, and adaptation planning. Platforms like Agri Care Hub promote proactive biosecurity worldwide.
How to Use
- Select species type (auto-loads dispersal rates from literature)
- Enter current range, dispersal ability, climate velocity, and habitat availability
- Set projection period
- Get instant future range, invasion risk index, and containment recommendations
When to Use
Use for risk assessments of new invasives, climate-driven pest migration, or planning, or monitoring tiger mosquito, fall armyworm, or emerald ash borer spread.
Purpose
To make world-class invasion biology instantly free – helping stop harmful species before they explode.
Scientific Foundation
Future range ≈ Current × (1 + r × t)²
Expansion velocity = dispersal + climate velocity × suitability
Risk Index = log(range growth) × habitat × dispersal
Conclusion
The Range Expansion Calculator turns silent spread into visible, preventable risk. Protect ecosystems and farms with help from Agri Care Hub.
