What it looks like
Gillman’s Goldenrod is an herbaceous perennial plant that grows to 30-120 cm in height. It has tiny yellow flowers clustered into heads. It can be easily mistaken for Hairy Goldenrod (Solidago hispida) and Bog Goldenrod (Solidago uliginosa), which can occur in the same habitats.
Where it lives
This plant is only found in open Great Lakes sand dunes with sparse vegetation and patches of bare sand on the shores of Lake Michigan and northern Lake Huron in Wisconsin, Michigan, Indiana and Ontario.
Where it’s been found in Ontario
In Ontario, Gillman’s Goldenrod is only known to occur in two locations on Great Duck Island in northern Lake Huron, south of Manitoulin Island.
What threatens it
Gillman’s Goldenrod has been impacted by a decline in habitat quality due to invasive species. A significant threat to Gillman’s Goldenrodis the invasive Glandular Baby’s Breath (Gypsophila scorzonerifolia). This species is now established at one of the locations where Gillman’s Goldenrod occurs in Ontario.
Action we are taking
Endangered species and their habitat are protected under Ontario’s Endangered Species Act, 2007.
A recovery strategy advises the ministry on ways to ensure healthy numbers of the species return to Ontario.

What you can do
Report a sighting
Submit your observations of species at risk to the Natural Heritage Information Centre (NHIC), which is Ontario’s conservation data centre. Join the “(NHIC) Rare Species of Ontario” project in iNaturalist to make submitting your observations quick and easy.
Volunteer with species at risk programs, such as community science surveys, through your local nature club, a provincial park or other conservation organizations.
Be a good steward
- Individuals, communities and organizations across the province who undertake stewardship or research activities that benefit species at risk and their habitats may be eligible to receive funding through the Species at Risk Stewardship Program (SARSP). The SARSP was created to encourage people to get involved in protecting and recovering species at risk in Ontario through stewardship actions.
