Rank Reasons
Meadow Willow (Salix petiolaris) occurs in central and eastern North America, in Canada and the northern United States. There are estimated to be more than 700 occurrences of Meadow Willow rangewide, and there are likely many occurrences with good or excellent viability. Threats include the loss of habitat due to conversion of its natural habitats for development or agriculture (such as for row crops or improved pasture), competition from invasive exotic plants, water management and impoundment with dams.
Range Extent Comments
Meadow Willow (Salix petiolaris) occurs in central and eastern North America, in Canada and the northern United States. It occurs in Canada from Nova Scotia, New Brunswick and Québec to Alberta and eastern British Columbia, and in the United States from Maine to Pennsylvania, Kansas, North Dakota, Colorado and eastern Montana. Range extent was estimated to be 5.3 million square kilometers, using herbarium specimens and photo-based observations documented between 1993 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 1993 and 2024, there are estimated to be more than 700 occurrences of Meadow Willow rangewide (GBIF 2024, iNaturalist 2024, SEINet 2024).
Threat Impact Comments
Threats to Meadow Willow include the loss of habitat due to conversion of its natural habitats for development or agriculture (such as for row crops or improved pasture), competition from invasive exotic plants, water management and impoundment with dams.
