Picea mariana
The bogs of the park are blanketed with sphagnum moss ("Sphagnum") from which grow black spruce ("Picea mariana") and Eastern larch ("Larix laricina"). Within the park’s Caribou Plain bog, three carnivorous plant species are found: pitcher plant ("Sarracenia purpurea"), sundew ("Drosera anglica"), and bladderwort ("Utricularia").
