Description

Lakeside Daisy is a small perennial plant in the aster family that reaches up to 35 centimetres in height. Dark green, toothless leaves surround the base of the plant. They may be narrowly lance-shaped or narrow at the base and broader toward the tip like a spatula. The plant produces one to 10 flowering stems with a single flower head per stem. The flower heads consist of bright yellow ray florets and golden yellow disk florets. Flowers bloom in early spring and are stunning against the barren rocky landscape where Lakeside Daisy grows. The seeds are scattered by the wind and gravity.

Range

The Lakeside Daisy is restricted to the Great Lakes region of North America, and is present in Ohio, Illinois, Michigan and southern Ontario. In Ontario, based on information available in 2002, it is believed to be present at 38 places on southern Manitoulin Island and the Bruce Peninsula. This species is globally rare but locally common in Ontario, where some populations consist of thousands of plants.

Habitat

In Ontario, Lakeside Daisy is found in grassland and pavement alvars, which are areas of exposed bedrock with very little soil. This rare habitat is kept fairly open and sunny by natural disturbances, such as drought and fire, which remove trees and shrubs that would otherwise shade-out sun-loving plants like Lakeside Daisy.

Threats

The main threat to Lakeside Daisy is habitat destruction due to limestone quarrying and development in rural areas. This plant also lives in areas that are popular for hiking and recreation and it can be accidentally trampled and damaged.

Protection

Lakeside Daisy receives protection under Ontario’s Endangered Species Act and the federal Species at Risk Act.

What You Can Do to Help the Lakeside Daisy

  • The Ministry of Natural Resources tracks species at risk such as the Lakeside Daisy. You can use a handy online form to report your sightings to the Natural Heritage Information Centre. Photographs with specific locations or mapping coordinates are always helpful. nhic.mnr.gov.on.ca
  • Report any illegal activity related to plants and wildlife to 1-877-TIPS-MNR (847-7667).
  • Private land owners have a very important role to play in species at risk recovery. If you find Lakeside Daisy on your property, you may be eligible for stewardship programs that support the protection and recovery of species at risk and their habitats.
  • Volunteer with your local nature club or provincial park to participate in surveys or stewardship work focused on species at risk.
  • Pollinators, such as bees, are in steep decline across the globe and they play a key role in the survival of many of Ontario’s rare plants. For information on how you can help scientists monitor pollinator populations in Ontario visit: www.seeds.ca/proj/poll.
