Hackelia bella

Hackelia bella is a perennial herb found in open habitats, such as openings of yellow pine and red fir forests, ridgetops, roadsides, and streambanks. It is endemic to the western United States in southwestern Oregon and northwestern California in the Klamath Ranges and High North Coast Ranges. There are over 21, but likely fewer than 80, occurrences rangewide, which face threats from cattle grazing, rights-of-way maintenance, logging and plantation maintenance, and other threats in some places. Monitoring of populations should be conducted to improve our understanding of reproduction, plant abundance, threats, and trends, as well as continuing conservation measures to protect the taxon.

Hackelia bella is endemic to the western United States in southwestern Oregon (Jackson and Josephine counties) and northwestern California (Humboldt, Mendocino, Siskiyou, Tehama, and Trinity counties) in the Klamath Ranges and High North Coast Ranges (Jepson Flora Project 2025). Range extent was estimated to be over 18,000 square kilometers using herbarium specimens, photo-based observations, and NatureServe Network occurrence data documented between 1994 and 2025, and increases to greater than 25,500 when potentially historic observations are included (GBIF 2025, iNaturalist 2025, NatureServe 2025, RARECAT 2025, SEINet 2025).

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 over 21, but likely fewer than 80, occurrences rangewide (GBIF 2025, iNaturalist 2025, NatureServe 2025, RARECAT 2025, SEINet 2025).

Although threats are not widely documented, this species is threatened by cattle grazing, rights-of-way maintenance, logging and tree plantation maintenance, and other threats in some places, though there is insufficient data, including anecdotal accounts, to understand scope and severity of threats for this species (NatureServe 2025).
