How Data was collected?
Techniques such as pitfall traps, opportunistic encounters, road kills encounters and nocturnal road cruising were used to collect data. Secondary information on snake rescue were also taken from NGOs like Wildlife Trust of India and Fauna Foundation of India.
Concerns over population
Rapid urbanization is the main cause of concerns for reptilian population, including snakes in cities. Green spaces are reducing with increasing urbanisation. Thus, future planning should include plans for preservation of green spaces and wildlife.
How Delhi is an important site for conservation?
Delhi is an important site for conservation because it is a part of ancient Aravalli mountains. Though, it has now fragmented either in the form of urban forests or urban parks. Despite that, it experiences regular snake occurrences across houses, gardens and industrial areas. Thus, Delhi still has good potential and provides an opportunity to conserve native flora, fauna and biodiversity.
