About Pallikaranai marshland: 

  • It is a freshwater marsh and partly saline wetland situated about 20 kilometres south of the city of Chennai,Tamil Nadu.
  • On its eastern periphery, the Marsh is flanked by the Buckingham Canal. 
  • The diverse ecosystem of the marshland supports some 115 bird species, ten mammals, 21 reptiles, ten amphibians, 46 fish, nine molluscs, five crustaceans, and seven butterfly species.
  • These include notable species such as Russell’s viper (Daboia siamensis) and birds such as the glossy ibis (Plegadis falcinellus), grey-headed lapwings (Vanellus cinereus) and Pheasant-tailed jacana (Hydrophasianus chirurgus).

  • It is one of the Ramsar sites from India.

 


Q1) What is Marshland?

Marshland, often referred to as a marsh, is a type of wetland characterized by the presence of water, primarily shallow and slow-moving, as well as the growth of emergent vegetation, which is plant life that is rooted in the water but extends above its surface. Marshes are transitional ecosystems located between open water bodies (such as lakes, rivers, or oceans) and dry land.
