Why is the American Chaffseed important?
American chaffseed is a hemiparasitic herb that parasitizes the root of a host plant by a specialized organ called the haustorium. Through the haustorium, it acquires nutrients and water from the host plant.
How many American Chaffseed are there?
Currently, 51 populations are known, including one in New Jersey, one in North Carolina, 43 in South Carolina, four in Georgia, and two in Florida.
Is the American Chaffseed endangered?

Is American chaffseed an endangered species?
American chaffseed was listed as an endangered species under the Endangered Species Act in 1992. Download the recovery plan. Protect existing populations and manage habitat with a high fire return interval (1-3 years). Reintroduce American chaffseed into the northern and southern portion of the current range.
Is American chaffseed a hemiparasite?
American chaffseed is a hemiparasitic herb that parasitizes the root of a host plant by a specialized organ called the haustorium. Through the haustorium, it acquires nutrients and water from the host plant. Because American chaffseed retains chlorophyll and can undergo photosynthesis, it is a hemiparasite – only half parasitic.
Is the population of chaffseed decreasing in South Carolina?
Population monitoring reports in South Carolina appear to suggest a trend of sharp population decline and/or extirpation following five years of fire suppression or exclusion for small populations. American chaffseed has a tolerated fire frequency range of 1-6 years and a pre-settlement fire frequency range of 1-3 years.
