COSEWIC Status Reports

  • COSEWIC Assessment and Status Report on the Showy Goldenrod Solidago speciosa in Canada (2011)

    Showy Goldenrod (Solidago speciosa) is a perennial plant in the aster family. Plants have as many as 30 stems up to 1.5 m tall. These are typically unbranched, smooth, and usually reddish in colour with alternate, lance-shaped leaves. The inflorescence is large and showy, up to 30 cm long, consisting of many small, bright yellow compound flower heads arranged into a panicle. Its branches are erect, and do not curve downwards like those of other large goldenrods. Flowering in Ontario starts in late August to early September and continues into mid-October.

Response Statements

  • Response Statement - Showy Goldenrod, Great Lakes Plains population (2011)

    Two small populations of this showy perennial occur in remnant tallgrass prairie habitats in southwestern Ontario. Substantial declines in the number of mature individuals and the quality of habitat have been recorded and are projected to continue. Limiting factors include the encroachment of woody plants due to the lack of regular burning of the prairie habitats and other impacts such as the spread of invasive exotic plants, and seed predation that reduces the species’ ability to reproduce.         

COSEWIC Annual Reports

  • COSEWIC Annual Report - 2010 - 2011 (2011)

    Under Canada’s Species at Risk Act (SARA), the foremost function of COSEWIC is to “assess the status of each wildlife species considered by COSEWIC to be at risk and, as part of the assessment, identify existing and potential threats to the species”. COSEWIC held two Wildlife Species Assessment Meetings during the past year assessing the status or reviewing the classification of a total of 92 wildlife species.
