Fig. 2

Map of the Kathmandu district showing the individual sampling sites and approximate areas in which sampling sites were visited. Shows a map of the Kathmandu district in which the locations of sample acquisition are indicated. Sampling sites that could be localised are shown as dots with connected boxes (continuous frame). Hatched areas with connected boxes (dashed frame) each represent one sampling site for which only the area could be localised. The boxes contain the corresponding priority number of the sampling site. The orange colour indicates that the sampling was done by Team C, whereas the red colour indicates sites that were visited by Team D. The source of the map data was Google Maps ©2023 (Mountain View, CA, USA). The base map was extracted from this using Microsoft Snipping Tool version 2022.2410.21.0 (Microsoft Corp., Redmond, WA, USA). Sampling locations and areas were marked using Microsoft Paint version 11.2410.28.0 (Microsoft Corp., Redmond, WA, USA), and lines and text fields were added using Microsoft Word MSO 365 version 2411 (Microsoft Corp., Redmond, WA, USA). (a): localised sampling sites and (b) localised sampling sites and hatched areas corresponding to one sampling site each, which were documented as area only.
