Within the tundra, some dominant plant species include lichen, cotton grass, and Arctic willow. Lichens. Lichens dominate the tundra as the region's major primary producer. A symbiotic combination of algae and fungi, a lichen is able to survive in the harsh conditions of the tundra (Biodiversity Institute of Ontario et al. 2010).
Alpine tundra in the North Cascades of Washington, United States. Alpine tundra does not contain trees because the climate and soils at high altitude block tree growth. [26]: 51 The cold climate of the alpine tundra is caused by the low air temperatures, and is similar to polar climate. Alpine tundra is generally better drained than arctic ...
The tundra climate is a polar climate sub-type located in high latitudes and high mountains. It is classified as ET according to the Köppen climate classification . It is a climate which at least one month has an average temperature high enough to melt snow (0 °C [32 °F]), but no month with an average temperature in excess of 10 °C (50 °F ...
At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands and shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species.
The Arctic is rapidly changing from the climate crisis, with no "new normal," scientists warn. Wildfires and permafrost thaw are making the tundra emit more carbon than it absorbs.
While the taiga has a more moderate climate and permits a diversity of both non-vascular and vascular plants, [3] the tundra has a limited growing season and stressful growing conditions due to intense cold, low precipitation, [4] and a lack of sunlight throughout the winter. [5]
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra .
The ecoregion is a transition zone between the taiga forests to the south, and the treeless arctic tundra to the north. 50% of the territory is herbaceous cover, 18% moss and lichen, 6% shrubs, and about 1% tree cover in protected areas and along river courses. [ 3 ]
