Jæren is one of the main agricultural districts in Norway, lying west and south of the city of Stavanger. The area is defined as the rectangle from Lake Søylandsvatn and Lake Lonavatn in the south (c.5 km apart), stretching about 27 km northwards to Hafrsfjord. The landscape is gently undulating, and the site includes several lakes, sand-dune shores, stone/boulder beaches and some shallow sea. The lakes have a rich aquatic vegetation.
This is the core breeding area for Crex crex in Norway, and one of the most important wintering and staging areas for inland waterbirds in Norway, with more than 10,000 occurring in winter. Notable wintering species include Gavia stellata (25), G. arctica (6), G. immer (20), G. adamsii (occasional) and Podiceps grisegena (110).
