The vascular flora of Terra Nova National Park, Newfoundland, Canada: a biodiversity analysis from a biogeographical and life form perspective
Terra Nova National Park, located on the east coast of Newfoundland, has a vascular flora of 535 taxa, including 33 rare species and 94 introduced taxa. About 75% of the native flora of the Park is composed of hemicryptophyte and cryptophyte species. Phanerophytes and nanophanerophytes represent onl...
