Sweden has a tradition of managing semi-natural pastures with a relatively high amount of trees and bushes. Some of the typical habitats also have low fodder value, but it is often not correlated with tree density. These pastures are mainly alvar grazing (habitat type 6280, Nordic alvar and Pre-Cambrian calcareous flatrocks) as well as forest pasture (partly habitat type 9070, Fennoscandian wooded pastures) and mountain pasture. These pastures cover a total of over 50 000 ha, approximately 10 % of all semi-natural pasture in Sweden.
