Conservation assessments - GIS tools 

Sampled Red list Index New

Red Lists are widely used to indicate species at risk of extinction. Presented here are GIS tools that integrate with specimen data, to firstly produce preliminary conservation assessment and to help any assessors support their assessments. 

These tools are to be used with specimen data or sighting data in latitude and longitude and have been primarily designed to work with herbaria data which provides an important source of data relevant for Red List assessments. 

The tools below follow the IUCN red listing guidelines, and produce data for Area of Occupancy, Extent of occurrence, number of sub-populations, number of locations and indicators of fragmentation.
