The territory of the Kerzhensky Reserve is a part of the Kamskoye-Bakaldinskoye group of wetlands of international importance.
On February 2, 2011, it was 40 years since the signing of the Ramsar Convention on Wetlands. The parties to the Convention are 160 countries; 1912 wetland complexes with a total area of 187 million hectares are included in the international list of wetlands.
One of the main conditions for joining the Ramsar Convention is that the government of the country declares at least one Ramsar Site on its territory. Resolution No. 1050 of the Government of the Russian Federation of 13.09.1994 approved a list of 35 Ramsar Sites of Russia with a total area of about 10 million hectares. Information on the status of all wetlands included in the Ramsar List is contained in the Wetlands International database and is continuously updated.
What are wetlands? According to the definition adopted by the International Convention on Wetlands (Ramsar, Iran, 1971), wetlands include a wide range of water bodies, shallows, and excessively wetted areas where the water mirror is usually on the surface. Everywhere in these areas, water is the main factor that determines the living conditions of plants and animals and controls the state of the environment.
