The Ferns of Galiano Island, BC

Last updated July 2018

To date our community has documented a total of 10 species of fern for Galiano Island, confirming 91% of the historical records and adding 2 new species to the list. A total of 11 species are now reported for the island—with the moonwort Sceptridium multifidum still at large!

With 409 species known within the Georgia Depression and 859 species reported for British Columbia, our dataset represents a tiny fraction of the total spider diversity of our region. If you would like to contribute to our knowledge of Galiano Island’s spiders, please add your observations to the Biodiversity Galiano project. Because spider taxonomy often relies on the study of minute sexual characters, however, it is often necessary to collect specimens to identify them to species. Even then, they must be sexually mature! Spiders are also sexually dimorphic, so you can expect a fair amount of morphological variation in a given species. For more information on spider identification and collection, please don’t hesitate to contact the project curator.

Below you can explore a diagram showing the species reported for Galiano, organized by family (note the diagram does not show relationships between families, only species).

Our community is especially indebted to Robb Bennett, Darren Copley and Claudia Copley at the Royal BC Museum for their support of this project.
