Rank Reasons
Acer negundo is a wide ranging deciduous tree occurring across much of the United States and southern Canada in it's native range. It is introduced and naturalized throughout Europe and Asia. With a large range extent, thousands of occurrences, broad habitat preferences and abundant habitat, and no intrinsic vulnerabilities, this species is considered secure.
Range Extent Comments
Acer negundo is a widespread taxon of the United States, Mexico, and southern Canada. Range extent was estimated using herbarium specimens and photo-based observations documented between 1993 and 2024 (GBIF 2024, iNaturalist 2024).
Occurrences Comments
By applying a 1 km separation distance to herbarium records and photo-based observations documented between 1993 and 2024, it is estimated that there are over thousands of occurrences rangewide (GBIF 2024, iNaturalist 2024).
