Introduction to the Anzali Lagoon

The largest port in Iran on the southern coast of the Mazandaran Sea is the Anzali lagoon port in Gilan province. The people of this region consider the lagoon to be one of their city’s most famous natural attractions and call it “Anzali Sel” in their Gilaki language. Some believe that the name Anzali comes from the word Hamzali, which means proximity of water and land in Gilaki. Additionally, in Greek, words such as “Anzelios” and “Anzelia” are synonymous with the word lagoon.

According to studies, the formation of this International Lagoon was caused by the deposition of fine-grained sand with a thickness of approximately 450 meters on the coastal margin. This process surprisingly happened in the last 70 to 100 thousand years. The underwater sediments date back to about 15 thousand years before the new Caspian Sea sediments formed. Eventually, the seawater retreated, and the alluvial deposits in the coastal plain emerged from the water, forming a long strip.

The Anzali lagoon is widely recognized as one of the most stunning and significant lagoons in Iran, and it is a habitat for a variety of terrestrial and marine ecosystems. It was also one of the first international lagoons recorded in Iran and was registered in the list of international lagoons of the Ramsar Convention in 1975.

Did you know that Anzali Lagoon is related to Kushiro Lagoon in Kushiro Shitsugen National Park, Japan? Anzali Lagoon is a freshwater wetland that boasts unique landscapes and biodiversity. It contains several islands and locations, including Bandar Anzali and Abkenar, two coastal cities.

The size of Anzali Lagoon varies according to weather patterns and seasons. During the rainy season, it can span approximately 120 square kilometers, while it may shrink to roughly 80 square kilometers during drier seasons. These conditions also affect the depth of the lagoon, which reaches a maximum of 5.2 meters in the rainy seasons.

Due to its location, Anzali lagoon is different from other wetlands because of its humidity and water quality. As a coastal wetland, it functions as a natural purification system and connects to the Caspian Sea through a shipping channel. It is home to a diverse range of animals and offers breathtaking views throughout. Visitors to Anzali Lagoon can also enjoy the sight of beautiful water lilies, whose pink color adds to the lagoon’s dreamlike ambiance as they sway with the water’s movement.

The Marginal Plant Layer or Footing

Plants that grow at the edge of lagoons and rivers are known as marginal plants. Their roots are in the soil and lower part in the water, while their vegetative part, including leaves and flowers, is outside the water. Examples of marginal plants are Common Reed, Water Mint, Water-plantains, Longleaf Pondweed, Flowering Rush, Knotweed, and Lotus.

In the wetland area, reeds cover around two-thirds of the land. However, the most famous plant in the world-renowned Anzali Lagoon is the Lotus. This beautiful plant grows from the end of June through the end of summer. Before blooming, it’s called sea pistachio, and in the local language, it’s known as Thaale Baghli (Nelumbium). The Lotus has large flowers with thick and numerous pink petals, growing in layers of broad green leaves, which adds a specific attractiveness to this area. The plant’s green cap and little seeds are functional in traditional medicine due to their therapeutic and medicinal properties.

The Floating Plants Layer

Floating plants are plants that float on the water’s surface, and their significant parts, especially the leaves, are on top of it. The roots of these plants are in the wetland bed, and their flowers are floating or out of water. Shalween, Lemna minor, Sea Sage, Knotgrass, Water moss, Common Frogbit, Yellow Water-lily, and White Water-lily are among the floating plants of Anzali Lagoon. The Water-lily is a large flower with red, white, and blue colors, which keeps its roots in the water so that its gorgeous flowers decorate the water like a gem. In addition to its beautiful appearance, this flower has a sacred place in various religions, especially in Eastern schools. The Water-lily flower is pure and holy because it hardly comes out of the mud.

The use of this flower in the architecture of Taq-e Bostan and Persepolis indicates its importance in Persia. Also, the appearance of its name in the poems of Iranian poets shows its place among artists. One of the main places where Marsh Terns lay eggs and hatch is the area where Water-lily flowers grow. Marsh Terns lay their eggs on a plant called Water Chestnut, and their chicks are born there.
