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 flora of the alpine tundra is characterized by plants that grow close to the ground, including perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [28] The flora is adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, and a short growing season.
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 ...
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.

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]
The lagoon that forms the heart of Izembek National Wildlife Refuge on the Alaska Peninsula has also long been recognised as an important staging ground for migrating birds. Other birds of the coastal wetlands include bristle-thighed curlew , dotterel , bar-tailed godwit , and Pacific golden plover while seabirds of include Steller's eider and ...
The Interior Yukon–Alaska alpine tundra ecoregion (WWF ID: NA1111) covers alpine, sub-alpine, and boreal forest areas along the cordillera (chain of mountain ranges) of Interior Alaska and south-central Yukon Territory. Geologically, they are the disjunct uplands of the Yukon–Tanana terrane plus a southern extension of the Brooks Range. The ...
