Environmental variables were used to assess the species distribution model of the blue mahseer.

These include: (<b>A</b>) annual mean temperature (°C), (<b>B</b>) annual total precipitation (mm), (<b>C</b>) elevation, (<b>D</b>) distance to rivers, (<b>E</b>) slope, (<b>F</b>) aspect, (<b>G</b>) flow direction, and (<b>H</b>) flow accumulation. The data for variables (A–H) were obtained from the Land Development Department (2021) and are free for use with no restrictions. Additionally, (I) NDWI and (J) NDVI were derived from Landsat 8 satellite images taken from January to April 2023. These images were accessed via the USGS Earth Explorer (2023), and Landsat data is freely available for use.
