NatureServe Status

Global Status: G5
Global Status Last Reviewed: 27Apr2016
Global Status Last Changed: 29Feb1984
Ranking Methodology Used: Ranked by inspection
Rounded Global Status: G5 - Secure
Reasons: Ceanothus americanus occurs in eastern North America from eastern Canada south along the Atlantic coast and west to Texas. This species is relatively rare in the northeastern portion of the range, but common elsewhere. C. americanus has been used for traditional medicine, but current commercial use is probably relatively minor. The roots are used in homeopathic medicine and entire plants are commercially available for landscaping. Should interest in this herb increase, wild populations should be monitored if wild-collection occurs, especially in the northeast where populations may be locally rare.

NatureServe Global Conservation Status Factors

Range Extent Comments: Eastern Canada south to Texas, including all of the eastern U.S.

Population Size Comments: Apparently relatively common in eastern North America, though relatively less common in the northeastern corner of its range. Rare in Delaware, Maine, Rhode Island, and Quebec. Throughout southern and western Wisconsin (Wisconsin State Herbarium Online, 2000). Common in Oklahoma, Missouri and Iowa and throughout Arkansas. Frequent in eastern and southern Ohio (Cooperrider 1995). Common in the Carolinas and Virginia (Weakley 2000, Draft). Throughout Tennessee. Present in Florida (Wunderlin and Hansen, 2000).

Overall Threat Impact Comments: This species is used for traditional medicine; however commercial use is probably relatively low (pers. comm. A. Bentley, December 2000, Foster and Duke 2000). However, some experts in the medicinal plant industry have suggested that trade is medium to large and demand has increased over the past ten years (Robbins 1999). Information regarding its use in homeopathic healing and its availability as a nursery plant is readily available. Populations in the northeastern portion of the range should be monitored since this species is considered rare throughout much of this area. Should its popularity as a medicinal plant increase, wild populations should be monitored; since both bark and roots are traditionally harvested, there may be potential for population decline, especially where the plant is locally rare.
