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.

 Delhi 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.
