This is due to the wide range of habitats provided by bedrock types, soil development, exposure, altitude range, and proximity to the ocean. From seashore to highland tundra there are many unusual niches in the park. Although the dominant character of the flora is boreal, colonies of arctic-alpine and temperate species have become established as climatic conditions fluctuated since the last glaciation. Rare plants are usually found in rare habitats, and Gros Morne, like the rest of the Great Northern Peninsula, has no shortage of either. Please resist the temptation to pick flowers.
Rare plants become rarer if they are unable to produce seeds.
