What is this tool

Freshwater AquaMaps is a tool for generating model-based, large-scale predictions of natural occurrences for species at a continental basin scale. The underlying model uses estimates of environmental preferences in terms of elevation, surface temperature, net primary productivity, soil pH, soil moisture, soil organic carbon, precipitation and compound topographic index.

Why use it

The Freshwater AquaMaps tool helps to identify areas for biodiversity conservation and provides an influential way forward for freshwater conservation. The Freshwater AquaMaps model has been standardised with input distribution maps for 69 European and 345 non-European species. The embedded Freshwater Checklist tool, for example, can generate a list of fishes reported in a given ecosystem, along with their corresponding native range and displayed as a biodiversity map.

Using this tool

There are a number of ways to make use of the AquaMaps tool:
