Freshwater Threatened Species Distribution Maps for New South Wales

Indicative distribution maps for a number of freshwater threatened species in New South Wales, Australia, modelled from recorded sightings and environmental conditions. The maps are provided by the NSW Department of Primary Industries and Regional Development and were last updated in May 2026. Modelled maps are not available for all listed species due to limited records or modelling constraints.

Use Cases

• Identify potential habitats for conservation planning based on modelled species distributions.
• Assess environmental impact on freshwater ecosystems by overlaying species distribution maps with other spatial data.
• Guide field surveys by highlighting stream segments with a high probability of species occurrence.
• Support species status reviews and reporting by providing spatial data on known and expected distributions.

Strengths

• Maps are based on the best available knowledge and understanding at the time of production.
• Distribution modelling uses recorded species locations and correlated environmental attributes.
• Data is provided under a CC-BY-4.0 license, allowing for flexible reuse.

Limitations

• The data and records are explicitly stated as not comprehensive.
• Maps are limited to NSW and may not reflect distributions extending beyond state borders.
• Modelled indicative distribution maps are not available for all listed freshwater threatened species due to data or modelling limitations.
