Not Listed
State Conservation Status Rank
S2
Imperiled in New York - Very vulnerable to disappearing from New York due to rarity or other factors; typically 6 to 20 populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines.
Global Conservation Status Rank
G3G4
Vulnerable globally, or Apparently Secure - At moderate risk of extinction, with relatively few populations or locations in the world, few individuals, and/or restricted range; or uncommon but not rare globally; may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors. More information is needed to assign either G3 or G4.

Summary

Did you know?

Goldenseal is highly valued for its medicinal properties and is now becoming more rare range-wide because it is being overcollected. Fortunately, it can also be grown in a nursery without disturbing wild populations.

State Ranking Justification

There are 20 existing populations and about 10 historical records. It is not expected that many more populations will be found and that the threat from collection and habitat destruction may increase in the future.

Short-term Trends

One site in eastern New York has been severely degraded but populations remain fairly stable throughout the rest of state.

Long-term Trends

Historical records show that this plant was never common in New York and the number of known occurrences has remained about the same over the last 100 years.

Conservation and Management

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.

Habitat

Habitat

Goldenseal colonies are found at the bottom or mid-slopes of rich woodlands, often near streams. Sometimes the slopes are deeply dissected by runoff or they may consist of limestone talus and cliffs. The forests are usually mature with old logs and an open understory with a diverse Spring wildflower flora. The underlying rock is usually limestone and the soils are rich in organic matter, sometimes with springs emanating from the slopes. (New York Natural Heritage Program 2007). Deep rich woods (Fernald 1970). Deep rich woods (Gleason 1952).

Associated Ecological Communities

  • Calcareous talus slope woodland (guide)
    An open or closed canopy community that occurs on talus slopes composed of calcareous bedrock such as limestone or dolomite. The soils are usually moist and loamy; there may be numerous rock outcrops.
  • Floodplain forest (guide)
    A hardwood forest that occurs on mineral soils on low terraces of river floodplains and river deltas. These sites are characterized by their flood regime; low areas are annually flooded in spring, and high areas are flooded irregularly.
  • Limestone woodland (guide)
    A woodland that occurs on shallow soils over limestone bedrock in non-alvar settings, and usually includes numerous rock outcrops. There are usually several codominant trees, although one species may become dominant in any one stand.
  • Maple-basswood rich mesic forest (guide)
    A species rich hardwood forest that typically occurs on well-drained, moist soils of circumneutral pH. Rich herbs are predominant in the ground layer and are usually correlated with calcareous bedrock, although bedrock does not have to be exposed. The dominant trees are sugar maple, basswood, and white ash.
  • Oak-tulip tree forest (guide)
    A hardwood forest that occurs on moist, well-drained sites in southeastern New York. The dominant trees include a mixture of five or more of the following: red oak, tulip tree, American beech, black birch, red maple, scarlet oak, black oak, and white oak.

Range

New York State Distribution

Goldenseal occurs from Rennselaer County south to Orange and Dutchess Counties and west to Niagara and Erie Counties. Most collections are from western New York.

Global Distribution

Goldenseal occurs from the Eastern United States northward into Ontario. It is common in Arkansas, Indiana, Illinois, Kentucky, Missouri, Ohio, and West Virginia and uncommon around the range perimeter. Hydrastis is presently cultivated to a limited extent within its historical range as well as in Oregon and Washington (Kauffman 1996).

Identification Comments

General Description

A small herbaceous plant usually growing in groups with one small leaf at the bottom and two large leaves at the top of the hairy stem. The leaves are heart-shaped with five-seven toothed lobes. There is one flower at the top of the stem composed of showy white stamens. This matures into a round cluster of showy red berries.

Best Life Stage for Proper Identification

It is best to search for this plant when the leaf is present with a flower or fruit. However, the distinctive leaves can be used for identification when flowers and fruits are absent.

Similar Species

This species may be confused for Mayapple, Podophyllum peltatum, or Canada waterleaf, Hydrophyllum canadense, when not in flower. Mayapple has a peltate leaf with lobes that are split into two smaller lobes at the tip and a single white flower blooms below the leaves. Canada waterleaf has lobes with larger teeth and a very rough surface and the light lavender flowers bloom in clusters just below the leaf blades.

Best Time to See

Hydrastis canadensis flowers in May. Its red fruits mature June through August.
