The vegetation of the Øvre Heimdalen valley

The catchment area of Øvre Heimdalsvatn reaches from the upper half of the subalpine birch forest zone to the lowermost part of the high-alpine subzone within the alpine zone. The units dominating the area include mountain birch forest, tall herb meadow, mire vegetation, bilberry heath, snowbed communities, chionophobous heath vegetation, and areas without a continuous vegetation layer. It is shown that the potential natural vegetation corresponds closely to the actual vegetation distribution.
