Gros Morne National Park of CanadaNatural Wonders & Cultural TreasuresConnect with Nature!A Green InheritanceGros Morne National Park has quite a diversity of plant life, with over 700 species of flowering plants and 400 species of bryophytes (mosses, liverworts and hornworts), plus an estimated 400 species of lichens. This remarkable diversity is due to the wide range of habitats provided by bedrock types, soil development, exposure, altitude range, and proximity to the ocean. On the hills, conditions are cooler, windier, and moister than on the lowlands. Hiking from the seashore up onto the Long Range Mountains is a bit like travelling into the past, to a time when Newfoundland was covered with Arctic plants and animals. From seashore to highland tundra there are many unusual niches in the park for you to explore! Rare plants are usually found in rare habitats, and Gros Morne National Park, like the rest of the Great Northern Peninsula, has no shortage of either. Check out the information on rare plants found at Port au Choix and L'Anse aux Meadows National Historic sites! You can also read about the research project on the mountain fern on the Long Range Highlands of Gros Morne National Park. Please help us ensure that our nature and our past will always have a future by resisting the temptation to pick flowers. Rare plants become rarer if they are unable to produce seeds! Demonstrate respectable behavior by staying on established trails and stairways so as not to trample and kill our plants; recovery can take decades! Plant communities:Shoreline: Wind, Waves, and SpraySalt spray, wave erosion, and drying winds assault plants living along the seashore. Coastal plants protect themselves with waxy coatings, fleshy leaves, flexible stems, and compact growth. Sand dunes have developed at Shallow Bay and Western Brook beach.
Coastal TuckamoreBuffeted by storms and onshore winds, coastal white spruce and balsam fir trees develop into a contorted tuckamore forest. Salt spray and desiccation kill exposed buds. Growth occurs only on the protected side of these trees, so they seem to lean away from the sea as they grow. Krummholz und KampfKrummholz are trees dwarfed by climatic conditions. Treeline marks the highest point at which normal tree growth can occur. In Gros Morne, treeline is at about 500 metres above sea level. This is sometimes called the kampf or struggle zone.
Lowland BogsSphagnum moss builds bogs. The moss grows on wet soils, and pumps out acid to obtain nutrients. As the moss blanket spreads, the low oxygen content of the soil slows decay. Thick peat mats slowly accumulate. Riverine ThicketThe richest and deepest soils accumulate along streams. Spring floods deposit sand, silt, and organic matter on terraces and in beaver ponds. These become gardens of wildflowers. Thickets of speckled alder cling to river banks, and waist-high grasses sway in wet meadows.
Larch ScrubThis is an open forest of twisted larch trees rooted in mucky soil. Beneath the larch grow shrubby dwarf birch and sweet gale. Balsam Fir Forest - Wave ForestIn places, a wave-like pattern of dead and living balsam fir trees stand out. This wave forest is probably created by wind damage and subsequent fungal attack of roots. Over the years, waves of dead trees and regrowth progress slowly uphill. Balsam Fir Forest- LowlandsBalsam fir with white spruce and white birch, as mature stands and successional scrub after logging.
Balsam Fir - Highland ForestThis is a mountain valley forest of well-spaced, old balsam fir trees. Their tops are wind pruned, and their lower branches are bowed downward by the weight of snow. Heath BarrensDense tangles of shrubs such as sheep laurel, blueberry, Labrador tea, and rhodora blanket the lowlands. In Newfoundland, the term "barrens" is used to denote any land not covered in forest.
Sedge MeadowsSedges dominate these wet meadows. The soil is waterlogged peat, and the turfy expanses are punctuated with pools called flashets. Sometimes flashets form step-wise down a hillside, like terraced rice paddies. TundraWiry ankle-high shrubs are interspersed with mounds of diapensia and mats of creeping crowberry, bearberry, moss and lichens. A thin layer of black peaty soil overlies a veneer of sand on top of bedrock. Wind erosion is strong, causing soil blowouts.
FelsenmeerThese fields of frost-shattered rock are sorted into patterns by cycles of freezing and thawing. Colourful lichens encrust the rocks, and tiny shrubs grow in the sandy soil at the centre of the stone rings.
CliffsMany rare mosses grow on cool, north-facing cliffs in the Long Range. Small trees, shrubs, and other plants also struggle to live in the meagre soil of crevices. Serpentine BarrensRock barrens of peridotite rock with sparse dwarf trees and shrubs, cushion plants and unusual arctic-alpine plants of the Tablelands. Black Spruce Forest and ScrubBlack spruce and balsam fir forest, mainly on boggy ground of sphagnum mosses with a shrub layer of sheep laurel. Intertidal Salt MarshSalt tolerant herbaceous plants of intertidal mud flats. Samphire dominates the lower marshes and salt marsh sedges dominate the upper marshes.
