Top ten Ramsar sites in India to visit for birding

What are the Ramsar Sites?

Concerned about the declining state of wetlands worldwide, nations came together to address this issue by signing a convention aimed at safeguarding and preserving internationally significant wetlands. The convention, which was adopted in the Iranian city of Ramsar in 1971 and became effective in 1975, has garnered participation from nearly 90% of UN member states. These countries, known as “Contracting Parties,” have committed to upholding the convention’s three fundamental principles:

  1. Work towards the wise use of all their wetlands.
  2. Designate suitable wetlands for the list of Wetlands International Importance and ensure their effective management.
  3. Cooperate internationally on transboundary wetlands, shared wetland systems, and shared species.

There are 9 criteria in two groups on which basis we can declare a site as a Ramsar site. Apart from the other factors, there are criteria based on species and ecological communities, waterbirds, fish, and on other taxa. You can browse our popular birdwatching tours in India.

 

The Ramsar Sites in India

India boasts a total of 75 Ramsar sites, encompassing inland wetlands, human-made wetlands, and marine or coastal wetlands. These sites are also classified based on the ecosystem services they offer, namely Provisioning services, Cultural services, regulating services, and Supporting services. These invaluable sites face various threats, such as climate change, pollution, invasive species, human intrusion etc.

In this article, we will share information about 10 wetlands that are of international importance and a breeding ground for many bird species.
