The Grand Lake Meadows are home to over 480 vascular plant species. Vascular plants have an internal plumbing system that conducts water, minerals and nutrients through the plant. Included in this category are trees, shrubs, wildflowers, grasses, sedges,
horsetails, club mosses and ferns.
The plant communities in the Meadows contain an assemblage of species which are rarely found elsewhere in the province, making
this an exceptional and ecologically significant wetland.
A large number of provincially rare and uncommon species are in the Meadows, likely a factor of the unique climate and hydrology of this region. In fact, 20% of all vascular plant species
found are considered rare or uncommon in New Brunswick.
