The neighbouring rural areas include Trembling aspen Populus tremuloides, White spruce Picea glauca, Jack Pine Pinus banksiana, Black Spruce Picea mariana and muskegs Specifically Meadow Lake is situated in the Meadow Lake plain of the Boreal transition ecoregion in the Boreal Plain ecozone.

Scouler's willow is the most common upland willow through most of its range. It invades quickly and abundantly after fires and logging.(Viereck and Little 1972) Mineral soil seedbeds are required for seedling establishment (Forest Practices Branch 1997). In northern areas, it occurs in muskegs, willow thickets, disturbed areas, and forests.

Closer to the Canada–US border, the rain decreases and the vegetation changes to stands of cottonwood. Cottonwood are also common on the many islands of the Stikine. The valley floor along the river is a combination of muskegs and dense alder and willow thickets. The Stikine River delta is approximately wide and consists of grass flats, tidal marsh, and sand bars.

Northern hawk-owls are unevenly distributed and highly variable throughout the boreal forest. They live mostly in open coniferous forests, or coniferous forests mixed with deciduous species such as larch, birch, poplar, and willow. They are found in muskegs, clearings, swamp valleys, meadows, or recently burnt areas, and generally avoid dense spruce-fir forests. Winter habitat is usually the same as breeding habitat.

Ledum latifolium drawn by William Miller It is reported from Greenland, as well as from every province and territory in Canada and in the northeastern and northwestern United States (New England, New York, Pennsylvania, Michigan, Wisconsin, Minnesota, Idaho, Washington, Oregon and Alaska). It grows in bogs, muskegs, and open tundra, as well as occasionally on wet shores and rocky alpine slopes.

The current surface expression of the Shield is one of very thin soil lying on top of the bedrock, with many bare outcrops. This arrangement was caused by severe glaciation during the ice age, which covered the Shield and scraped the rock clean. The lowlands of the Canadian Shield have a very dense soil that is not suitable for forestation; it also contains many marshes and bogs (muskegs). The rest of the region has coarse soil that does not retain moisture well and is frozen with permafrost throughout the year.

They can tolerate a wide range of soil conditions but grow most commonly in swamps, bogs, or muskegs, in wet to moist organic soils such as sphagnum, peat, and woody peat. They are also found on mineral soils that range from heavy clay to coarse sand; thus texture does not seem to be limiting. Although tamarack can grow well on calcareous soils, it is not abundant on the limestone areas of eastern Ontario. Tamarack sapling in a sphagnum bog Tamarack is generally the first forest tree to grow filled-lake bogs.

The "St. John Reserve" Agricultural Settlement By Dorthea Calverley. The region grew slowly as agricultural settlements spread westward to the foothills of the Rocky Mountains and northward to the muskegs of the Liard. In 1932 Pouce Coupe became the first community in the region to incorporate as a village, followed by Dawson Creek in 1936 after a rail line was extended there from Alberta. The 1941 Canadian Census recorded 8,444 people in northeastern BC but a year later the Alaska Highway was constructed by 10,000 US Army servicemen connecting Dawson Creek to Alaska via Fort Nelson.

Many different kinds of wetlands exist, all characterized by unique compositions of plant life and water conditions. To list a few, marshes, swamps, bogs, fens, peatlands, muskegs, prairie pothole (landform), and pocosins are all examples of different kinds of wetlands. Because each type of wetland is unique, the same characteristics used to classify each wetland can also be used to characterize the amount of methane emitted from that particular wetland. Any waterlogged environment with moderate levels of decomposition creates the anaerobic conditions needed for methanogenesis, but the amount of water and decomposition will affect the magnitude of methane emissions in a specific environment.

The Pas, Manitoba saw its first car arrive in 1916, yet it had been active with fur trading posts and explorers in the area since 1741. Settlers would not only haul gravel for the new roadways, but they also cleared brush for the road allowance. Early roads did not follow the road allowances of the Dominion Land Survey, but rather kept to higher ground, however due to the nature of the Boreal transition ecoregion, muskegs and swamps still needed to be traversed. The first pioneers filled these watery areas with branches and brush and proceeded along their trip.

A wintry scene in Chequamegon–Nicolet National Forest A barred owl along a highway in the Nicolet National Forest Remote areas of uplands, bogs, wetlands, muskegs, rivers, streams, pine savannas, meadows and many glacial lakes are found throughout these forests. Native tree species include Acer saccharum (sugar maple), Acer rubrum (red maple), and Acer spicatum (mountain maple), white, red, and black oaks, aspen, beech, basswood, sumac, and paper, yellow, and river birch. Coniferous trees, including red, white, and jack pine, white spruce and balsam fir are abundant due to a dense second growth. Eastern hemlock are also present as this is the westernmost limit of its distribution.

Several other reasons may cause the environment to be too extreme for trees to grow. This can include geothermal exposure associated with hot springs or volcanoes, such as at Yellowstone; high soil acidity near bogs; high salinity associated with playas or salt lakes; or ground that is saturated with groundwater that excludes oxygen from the soil, which most tree roots need for growth. The margins of muskegs and bogs are common examples of these types of open area. However, no such line exists for swamps, where trees, such as bald cypress and the many mangrove species, have adapted to growing in permanently waterlogged soil.
