Rank Reasons
Solidago macrophylla is a perennial forb occurring in alpine and subalpine zones, in sandy and rocky soils, rocky ledges, open woods, and outcrops of eastern North America, from Ontario east to Newfoundland Island, Canada, south to Massachusetts, New York, and Michigan in the United States. There are over 400 estimated occurrences of this species, which are potentially threatened by development, rights-of-way construction and maintenance, invasive species, and other threats in some places. Little is known about threats and trends, but with a large range extent, large number of occurrences, abundant habitat, and broad habitat preferences, Solidago macrophylla is considered secure.
Range Extent Comments
Solidago macrophylla occurs in eastern North America, from Ontario east to Newfoundland Island, Canada, south to Massachusetts, New York, and Michigan in the United States (Kartesz 1996, FNA 2006, Native Plant Trust 2025). Range extent was estimated to be over 3 million square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1994 and 2025 (GBIF 2025, iNaturalist 2025, NatureServe 2025, RARECAT 2025, SEINet 2025).
Occurrences Comments
By applying a 1 km separation distance to herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1994 and 2025, it is estimated that there are more than 400 occurrences rangewide (GBIF 2025, iNaturalist 2025, NatureServe 2025, RARECAT 2025, SEINet 2025).
Threat Impact Comments
Although threats are not widely documented, Solidago macrophylla is potentially threatened by development, rights-of-way construction and maintenance, invasive species, and other threats in some places. However, their overall impact is likely negligible given the species' broad range, large number of occurrences, and affinity for typically abundant habitats.
Ecology & Habitat

Habitat

Solidago macrophylla occurs in "alpine or subalpine zones, forests, mountain summits and plateaus" (Native Plant Trust 2025), "sandy and gravelly soils, rocky ledges, and outcrops, [and] open areas in woods and thickets" from 0-1000 m in elevation (FNA 2006).

Reproduction

Solidago macrophylla produces flowers from August through September (FNA 2006).
