Rank ReasonsSalix herbacea occurs in northern North America, Greenland, and Europe. There are estimated to be more than 5000 occurrences, most are in eastern and northern Canada, Greenland, Iceland, Norway, northern Sweden, Scotland, Switzerland, and Austria. It may be threatened by recreation impacts in some alpine areas, competition with other plants, including invasive exotic plants may become a greater threat with increasing warming of the climate.
Range Extent CommentsSalix herbacea occurs in northern North America, Greenland, and Europe. Most occurrences are in eastern and northern Canada, Greenland, Iceland, Norway, northern Sweden, Scotland, Switzerland, and Austria. It also occurs in mountain ranges in other European countries. Range extent was estimated to be about 20 million square kilometers, using herbarium specimens and photo-based observations documented between 1993 and 2024 (FNA 2010, GBIF 2024, iNaturalist 2024).
Occurrences CommentsBy applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, there are estimated to be more than 5000 occurrences of Salix herbacea rangewide (GBIF 2024, iNaturalist 2024).
Threat Impact CommentsSalix herbacea may be threatened by recreation impacts in some alpine areas, competition with other plants, including invasive exotic plants may become a greater threat with increasing warming of the climate.
