The Orchids of Galiano Island, BC
Last updated December 2018
To date our community has documented 10 orchids (Family: Orchidaceae) for Galiano Island, confirming 91% of the historical records and adding 3 new species to the list. We have also documented a rare variety of coralroot orchid (Corallorhiza maculata var. ozettensis), which, outside of the southern Gulf Islands and southeast Vancouver Island, is only known from the northwest coast of the Olympic Peninsula. A total of 11 orchid species are now reported for the island. Of these reported species, the Alaska rein orchid (Platanthera unalascensis) remains undocumented on the project.
There are 39 species of orchid known to the Pacific Northwest (Legler 2018); 37 species known to British Columbia (E-Flora 2019); and 15 species known to the southern Gulf Islands (Janszen 2002). Our local orchid diversity thus represents less than a third of the broader regional and provincial diversity, and about 73% of the diversity reported for the southern Gulf Islands.
