Mapping tool for biodiversity risk assessments

Supporting cost effective decisions for environmental risk management

A Simple Index

For a chosen area, the LEFT tool assembles relevant environmental data from global databases. Within minutes, it produces a map displaying a simple index of ecological risk.

World-Class Algorithms

The LEFT tool uses algorithms formulated by researchers at the University of Oxford to assess the pattern of ecological features across a chosen area. These algorithms calculate the ecological risk index.

Local Assessments, Global Data

Any landscape in the world can be assessed - up to approximately 100,000km2 at a time. Output maps include information on: risk assessment; biodiversity; vulnerability; intactness; connectivity and resilience.

The LEFT Process

LEFT assembles data, performs an analysis and generates a report.

A decision support tool for planning

The algorithms for LEFT have been developed by our team at the University of Oxford, UK.
