Virginia Mallow (Sida hermaphrodita, Malvaceae) at the Taquanyah Conservation Area, Ontario, Canada: biology and interspecies interactions.

Virginia Mallow (Sida hermaphrodita) is a rare perennial plant native to North America. There are only two known populations in Canada, the largest being located at the Taquanayh Conservation Area, Haldimand County, Ontario. The Ontario Ministry of Natural Resources recently released a recovery strategy, which highlighted the need for additional biological information with regards to this species. To further the biological understanding of this species and preliminarily ascertain the best strategy of recovery, we compared the germination rates of seeds collected in different years and analyzed the propagation and transplant success using either seeds or root segments with buds. In addition, we conducted a vegetation survey to determine the species that are associated with S. hermaphodita in such way that an interspecies interaction study can be conducted in the future. Seeds of the 2012-growing season exhibited significantly higher germination rates than seeds of the 2013 season. Plants grown from seeds showed an increased aboveground height compared to plants propagated from root segments. The highest association frequency of S. hermaphrodita at Taquanyah was with Solidago canadensis and Phalaris arundinacea. Both S. hermaphrodita and its associated species were mapped to allow a future monitoring of their population dynamics.
