Rank Reasons
Silky Willow (Salix pellita) occurs in northeastern North America, in the United States in northern New England and the Upper Midwest and in boreal eastern Canada, as far north as the shores of Hudson Bay. There are estimated to be between 81 and 300 occurrences of Silky Willow rangewide, there are likely many occurrences with good or excellent viability. Most of the range of Silky Willow is in remote boreal areas of eastern Canada, threats may include competition from other woody plants, and insect defoliation which may increase with the warming climate in future decades.
Range Extent Comments
Silky Willow (Salix pellita) occurs in northeastern North America, in the United States in northern New England and the Upper Midwest and in eastern Canada. It occurs in Maine, New Hampshire, Vermont, Michigan, Wisconsin, and Minnesota in the United States, and in boreal Canada from Nova Scotia, Newfoundland and Labrador to the shores of Hudson Bay (Manitoba, Ontario, and Québec), west to Saskatchewan. Range extent was estimated to be 3.35 million square kilometers using herbarium specimens and photo-based observations documented between 1983 and 2024 (FNA 2010, GBIF 2024, iNaturalist 2024, POWO 2024, SEINet 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1983 and 2024, there are estimated to be between 81 and 300 occurrences of Silky Willow rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact Comments
Most of the range of Silky Willow is in remote boreal areas of eastern Canada, extending far north as Hudson Bay. Threats may include competition from other woody plants, and insect defoliation which may increase with the warming climate in future decades.
