Descrição

Monitor lizards, belonging to the family Varanidae and order Squamata, are ancient anguimorph reptiles found across Africa, South and Southeast Asia, and Australasia. They play a vital role as predators and scavengers in their ecosystems. The IUCN lists the Yellow Monitor (Varanus flavescens) as Endangered and the Bengal Monitor (Varanus bengalensis) as Near Threatened, while the Asian Water Monitor (V. salvator) and Desert Monitor (V. griseus) remain Least Concern. In India, all four species are protected under Schedule I, Part II of the Wildlife Protection Act (1972). These reptiles have drawn research interest due to their distinct morphology, behavior, and interactions with human settlements. However, their populations are declining due to urban expansion, habitat loss, pesticide use, and other human-driven threats.

With the continued support and enthusiasm, we’ve successfully conducted the Monitor Lizard (Varanus spp.) Count over the past two years. Following its initiation in 2022 and the overwhelming response received, we are excited to launch the 2024 edition. This initiative aims to assess the current population and distribution of monitor lizards across India while raising awareness by actively involving citizens in the process.
