Hydrastis canadensis L.

Threats [-]
This plant is collected for medicinal purposes but so far there is no evidence that it is being over-collected in New York. There is a moderate threat from habitat destruction, especially in the Lower Hudson area. Exotic species like garlic mustard and bush honeysuckle threaten its understory habitat.

Conservation Strategies and Management Practices [-]
The woodland areas where this species occurs need to be protected from disturbance that could introduce too much sunlight or invasive species to the site. If there are invasive species they need to be removed.

Research Needs [-]
Some research has been done on habitat preference by the College of Environmental Science and Forestry but there have been no results as of 2007. Research needs to be done on whether populations could be augmented at existing sites.
