Sudden Tract - Plant Inventory

 
Sudden Tract is a natural area in southern Ontario that harbours a very high diversity of species. The property is comprised of several ridges, in between which there are areas of marsh, shrub swamp, and swamp. I started maintaining a plant inventory of the area. Here is my list.
 
Introductory Notes
  • I use Newcombe's Wildflower Guide for common and scientific names (except for ferns, trees & shrubs I use Soper for shrubs, Farrar for trees, and the Owen Sound Field Naturalists fern book for ferns)
  • Please bear in mind that if there are obscure varieties of a species, I have not taken them into account. I use Newcombe's for 90% of my plant ID work.
  • This list is solely the result of my own work. I have not added species that others have found.
  • There is of course the possibility that I made some errors in identification. If there is a species listed here that is erroneously identified, I welcome corrections & advice -- please email me.
  • I have not updated the scientific names - the ones used here are from Newcombe's
