Plants of Petrie Island

by Christine Hanrahan (2003)

 

An initial list was compiled by Albert Dugal during a one-day visit in 1977. Additional observations were made by other naturalists in the 1980's and 1990's. This has resulted in an impressive but preliminary list of plants. Twenty-eight significant native plant species occur here. Significant species are those regarded as regionally or provincially rare or sparse.  These species are shown in boldface.
