Nestled on the eastern tip of Sobieszewska Island, the Mewia Łacha Nature Reserve stands as a testament to Poland's commitment to preserving its unique coastal ecosystems. Established in 1991, this protected area spans approximately 150 hectares, with 19 hectares situated on Sobieszewska Island itself. The reserve's primary objective is to safeguard the breeding grounds of various bird species and serve as a vital habitat for migratory and wintering avifauna.
Geographical Significance and Formation
Sobieszewska Island, located near Gdańsk, owes its insular character to both natural and human-induced changes in the Vistula River's course. In the 19th century, the river was redirected through an artificial canal known as the Vistula Dug-through (Przekop Wisły), leading to the formation of new estuaries and the eventual creation of the island. Mewia Łacha Reserve is strategically positioned at the mouth of this canal, encompassing dynamic landscapes shaped by riverine and marine influences.
Avian Diversity and Conservation
The reserve is renowned for its rich avian biodiversity, hosting nearly 275 bird species. It serves as a crucial nesting and resting site for migratory birds, including several rare and protected species. Notably, since 2007, Mewia Łacha has been the only place in Poland where terns have resumed nesting, highlighting the reserve's importance in avian conservation. The area is also frequented by various species of gulls and plovers, making it a haven for ornithologists and bird-watching enthusiasts.
Seal Population
Beyond its avian inhabitants, Mewia Łacha is distinguished by its seal population. The sandbanks and shallow waters at the river's mouth provide ideal resting spots for grey and common seals. Visitors often have the opportunity to observe these marine mammals basking in the sun, particularly during warmer months. This unique feature adds to the reserve's ecological value and visitor appeal.
Flora and Habitat Diversity
The reserve's dynamic environment, influenced by the interplay of river and sea, supports a diverse range of habitats. The coastline is characterized by sandy beaches, dunes, and periodically formed islets and shallow lagoons. This ever-changing landscape fosters a rich flora, including approximately 450 plant species, some of which are rare and protected. The presence of beavers further contributes to the habitat diversity, as their dam-building activities create additional ecological niches.

Mewia Łacha offers visitors a unique opportunity to immerse themselves in a pristine natural environment. A well-marked trail leads through the reserve, guiding visitors from the forested areas of Las Mierzei to the expansive sandy beaches and dunes. Along the way, observation platforms provide vantage points for bird and seal watching. The trail is generally considered easy, making it accessible to a wide range of visitors, including families and casual hikers.
