Public Attitudes toward Monitor Lizards (Reptilia: Varanidae): A Conservation Challenge in the Human-dominated Ecosystems of Bangladesh

Abstract

The present study investigated the public attitudes toward monitor lizards in the human-dominated ecosystems of sub-tropical Bangladesh. In this regard, a total of 100 participants between the age of 15-65 were randomly selected from five different parts (20 participants from each part) of Bangladesh. Based on participants’ opinion, Varanus bengalensis is mostly known (58±2.20) and Varanus salvator is the least known (22±3.48) species among three monitor lizard species found in Bangladesh. Surprisingly, most of the participants (77±0.50) mentioned that monitor lizards are snakes. Though all the monitor lizards found in Bangladesh are non-venomous, a significant proportion (63±1.53) of the participants believe that monitor lizards are venomous and can attack and bite people. The participants' viewpoint throughout the country regarding the above-mentioned issues, however, were somewhat similar (χ2 test, p> 0.05). Despite their negative perception, most of the participants (71±1.27) agreed that monitor lizards play vital role in our ecosystems. The populations of monitor lizards are declining day by day at an alarming rate. Most of the participants (32±0.50) mentioned that retribution killing is the primary cause of the decline of monitor lizards. The highest proportion (56±1.35) of participants believe that there are no alternatives of awareness raising among local residents if we are to conserve monitor lizards in their natural environment that is shared by people.
