Rank Reasons

Vernonia noveboracensis has a wide range in the eastern U.S. and over 300 occurrences estimated.

Range Extent Comments

The native range of Vernonia noveboracensis is from Massachusetts and New York south to Alabama and northern Florida (Flora of North America Editorial Committee 2006, Weakley 2023). It occurs as an exotic in New Hampshire, New Mexico, and Oklahoma (Haines 2011, BONAP 2014, Native Plant Trust 2023). Range extent was estimated using herbarium specimens, photo-based observations, and NatureServe Network occurrence data collected between 1992 and 2023 (GBIF 2023, iNaturalist 2023, NatureServe 2023).

Occurrences Comments

Based on NatureServe Network occurrence data, herbarium records, and photo-based observations documented between 1992 and 2023, there are over 300 occurrences rangewide (GBIF 2023, iNaturalist 2023, NatureServe 2023).

Threat Impact Comments

Highly threatened by land-use conversion and habitat fragmentation; human disturbance is reported to be a low-level threat (Southern Appalachian Species Viability Project 2002).

Ecology & Habitat

Habitat

Vernonia noveboracensis grows in abandoned fields, marshes, roadsides, pastures, bottomlands, streamsides, and wet ditches (Flora of North America Editorial Committee 2006, Haines 2011, Weakley 2023).
