The Beka Nature Reserve, established in 1988 on the Kashubian Coast at the mouth of the Reda River into the Puck Bay, protects unique salt meadows, wet sedge marshes, and the diverse flora and fauna of this area. The area of the reserve, initially 193.01 hectares, was increased in 2018 to include the waters of the Gulf of Gdańsk, expanding the area to 355.6 hectares and placing it under protection as part of two Natura 2000 areas: "Puck Bay" and "Puck Bay and the Hel Peninsula". The reserve includes unique halophytic plant habitats, including rare species such as Gerard's reed, sea milkwort, sea holly, and sea aster. In the northern part, fed with fresh water, you can find orchids such as marsh orchids and Loesel's twayblade, as well as other protected plants, including common butterwort.The Beka Reserve is a haven for many bird species, some of which, such as the common redshank and ruff, have ceased nesting here due to the overgrowth of reeds and tourist pressure. However, species such as the bittern, crane, oystercatcher, and lapwing can still be found, as well as the citrine wagtail, which nested here for the first time in 1995. The Reda River, which used to form a branched delta in the Puck Bay, has been regulated over the years, which, combined with the growing delta, continues to shape the character of the reserve. To preserve the open spaces of the meadows and restore habitats for waders, the Ogólnopolskie Towarzystwo Ochrony Ptaków (OTOP) implements conservation projects, including controlled cattle grazing and reed mowing.
