A canal runs through the middle of Ryaan Ranch. To help elephants move between the two sides without negotiating its steep banks, Ryaan Ranch Wildlife Trust built three bridges across it during 2025–2026. Once the bridges were in place, we wanted to observe how elephants used them and whether they continued to approach the open canal trench.
We installed green lights at all three bridges to mark the designated crossing points. Red lights were placed along sections of the open trench, where an elephant attempting to cross could slip or be injured. We also installed solar-powered cameras at the bridges to monitor elephant movement, including activity when our team is not present.
The cameras are an important part of this work. They allow us to see where elephants approach the canal, which crossings they use and how they move through the ranch. This helps the Trust assess the arrangements based on observed behaviour and identify anything that may need attention, such as a damaged crossing or a change in the route elephants take.
Our observations so far have been encouraging: elephants captured during monitoring have crossed by the bridges marked with green lights rather than through the open trench. Seeing them use the intended routes is a meaningful outcome for the team that planned and built the crossings.
We are continuing to study the footage. The observations show which routes elephants are taking, but they do not yet establish whether the colour of the lights itself influences their choices. The bridges may also be attractive because they provide easier ground underfoot. Continued monitoring will help us understand how elephants use these routes across different conditions and seasons.
The lights, cameras and bridges form one practical effort to reduce a known risk within the ranch. Ryaan Ranch Wildlife Trust will keep maintaining the system and watching how the elephants respond. Our aim is simple: to let elephants move through the land with fewer obstacles and less risk of injury.
