Southernmost Sweden contains a varied landscape with both plains and hilly terrain. A characteristic chain of elongated hills runs across Scania from northwest to southeast. These hills are horsts located along the Tornquist Zone. Some of the horsts are Hallandsåsen, Römelåsen and Söderåsen. The plains of Scania and Halland make up 10% of Sweden's cultivated lands and are the country's main agricultural landscape. Productivity is high relative to the rest of Sweden and more akin to that of more southern European countries. The natural vegetation is made up of broadleaf forest although conifer plantations are common. Southern Sweden has Sweden's greatest animal and plant diversity.
