Angarnsjöängen in early summer

Angarnsjöängen (Swedish: Lake Angarn Meadow, also spelt Angarnssjöängen) is a nature reserve circa 3 kilometres (3.0 km; 1.9 mi) northeast of Vallentuna, in Southern Uppland, Sweden.

It is a wetland with a varying water level depending on the weather. The water rises dramatically each spring as the snow melts and becomes very low by late summer and autumn, creating a good resting place for wading birds. A wetlands restoration project carried out in 1992 markedly increased both the numbers and the variety of birds visiting the site and nesting there.[1] A total of 250 bird species have been observed there during a year.

Among the bird species known to typically nest in the nature reserve are western marsh harrier, northern lapwing, common redshank and western yellow wagtail.[1]

The Bronze Age Örstar petroglyphs[2] and Runestone U 211 are both in the immediate vicinity. Angarn Church, dating from the 13th century, also lies close to the nature reserve.
