This category includes the Flora of Alaska, in Subarctic America. It includes flora taxa that are native to Alaska. Taxa of the lowest rank are always included. Higher taxa are included only if endemic. For the purposes of this category, "Alaska" is defined in accordance with the World Geographical Scheme for Recording Plant Distributions.
The adversity of soil and climatic conditions proves to low production levels, as well as little biomass accumulation due to slow rates of nutrient release in cold and wet soils, specifically as a result of limited nitrogen and phosphorus (Nadelhoffer et al. 1996) Additionally, there are low temperatures and strong winds in the tundra causing most vegetation to be dominated by woody plants ...
Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.

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 ...
Southeast Alaska has an unusual climate that allows a large number of edible plant and edible mushroom species to grow. The area consists primarily of the Tongass National Forest, which is a temperate rainforest. This rainforest has plenty of precipitation and the temperature remains relatively constant, therefore many plant and fungi species ...
This is a hilly area that lies between the boggier Arctic coastal tundra to the north and the Brooks Range to the south, and stretching from the Chukchi Sea east across northern Alaska to the border with Canada's Yukon Territory. The Noatak River valley is the only forested area. [2]
90% of natural habitat remains intact, except for the vicinity of Utqiaġvik, Alaska and the oil fields of Prudhoe Bay, Alaska and Kuparuk which are expanding along the coast and may in future spread into the Arctic National Wildlife Refuge, which is the only major protected area on this coast (see Arctic Refuge drilling controversy), and on ...
The slopes are covered with a variety of lichens and other tundra plants, depending on altitude and drainage. The low-lying, wetter areas are similar to the surrounding Beringia lowland tundra ecoregion but the uplands are generally drier and dominated by sedges such as Eriophorum vaginatum and scrub such as the ericas Arctostaphylos alpina, Vaccinium vitis-idaea or Empetrum nigrum or mountain ...
