Adder Vipera berus (Linneaus 1758) Distribution (Figure 10). Included records from Artportalen (N=1250): all reports have been included. Any confusion between melanistic Vipera berus and Natrix natrix would not affect the distribution pattern. Common and widespread in the Southern and Middle Boreal. Widespread and locally common in the Northern Boreal, where often found in areas of varied topography with south-facing slopes that offer early snowmelt and dependable hibernacula (Andersson 2003; Figure 20). Scattered observations have been made in the Subalpine and Low-Alpine zones (Curry-Lindahl 1975; Frislid & Semb-Johansson 1981; Elmberg 1995). The highest reported occurrences show a slightly decreasing altitude from south to north: 940 m in Härjedalen (Flatruet), 900 m in Jämtland (Oviksfjällen), 720 m in Lycksele lappmark (Kraipe), but 820 m in Lule lappmark (Aktse). Most of these concern south-facing sites in the upper Subalpine zone, but also above treeline in the Low-Alpine zone.
