Sensor-Based Lights Installed in Sundarbans to Prevent Tiger Straying into Villages
Patharpratima/Kultali, South 24 Parganas:
With the onset of winter, incidents of tigers straying out of forests and entering human settlements in the Sundarbans have been a growing concern. Between 2021 and 2023, such incidents were reported frequently, posing risks to both villagers and wildlife.
To prevent tiger intrusion, forest authorities had earlier installed protective nets along forest areas adjacent to villages. However, tigers often managed to slip through gaps and reach nearby human settlements.
In early 2024, the Forest Department introduced a pilot project by installing sensor-based special lights in the Thakuran-I and Thakuran-II forest compartments in Patharpratima. These lights function automatically after sunset and resemble the blinking red navigation lights seen on river buoys.
According to forest officials, the initiative has shown positive results. The movement of tigers towards villages, including Upendranagar and surrounding areas of Patharpratima, has reportedly reduced since the installation of these lights.
Encouraged by the success, the Forest Department has now started installing similar sensor-based lighting systems in forest areas adjacent to villages in Kultali. The primary objective is to restrict tiger movement within forest boundaries.
Authorities have planned to install around 300 sensor-enabled lights along protective nets and tree branches. Work has already begun. These lights will emit red, yellow, green and other colours after dark to deter tigers from moving towards inhabited areas.
Officials confirmed that a portion of the Ajmalmari 11th compartment forest area has been selected for the installation. The villages of Nagenabad and Deulbari, located near this forest, have previously witnessed multiple tiger intrusion incidents.
Forest officials believe that the brightness of these lights will discourage tigers from entering human settlements. If the project proves successful, similar systems may be installed in other vulnerable areas of the Sundarbans.
