Slow Worm Anguis fragilis Linneaus 1758 Distribution (Figure 8). Included records from Artportalen (N=360): as there are not any confusion species all reports have been included. Common and widespread in the Southern Boreal and the coastal southern part of the Middle Boreal. From Medelpad and northwards all records have been made within 60 km of the Baltic coast. The vast majority of records is from coastal areas or low altitudes in river valleys. Nevertheless, there are several records from above 300 m altitude in Hälsingland and Ångermanland, and a photo-documented occurrence at 425 m in Medelpad (15 km SW of Stöde). Although most common near the coast, the total lack of records from offshore islands in North Sweden indicates poor dispersal capacity over brackish water. There are no indications of changes in distribution during the last 50 years. Note, though, that the northernmost occurrence presented in the map (Figure 8; lower Byske River valley and the adjacent Tåme area to the north (Västerbotten)) ... : Published as part of Elmberg, Johan, 2023, Amphibians and reptiles in North Sweden: distribution, habitat affinities, and abundance (Classes: Amphibia and Reptilia), pp. 301-335 in Zootaxa 5301 (3) on page 319, DOI: 10.11646/zootaxa.5301.3.1, http://zenodo.org/record/8030434 ...
