Survival in the tundra

Survival in the tundra

The landmass known as the tundra is a true indicator of a Arctic climate.  It is a treeless barren area occurring south of the polar ice cap worldwide.  The tundra flora becomes progressively impoverished (sparser) the closer it is to the ice cap, creating bands of differing vegetation.  The tundra "trees" consist of dwarf willow (Salix), birch (Betula), and heaths.  The heath (Ericaceae) family-which includes familiar plants like rhododendrons, azaleas, heather, and mountain laurel (Kalmia latifolia)-is prepresented in this zone b dwarf shrubs such as Labrador tea (Ledum).  They are characterized by small, thick, evergreen leaves and shallow root systems that are particularly well adapted to the acidic, boggy conditions of low Arctic tundra.  Some  Vaccinium species occur throughout the Arctic Circle (the circumpolar north) in all but the highest Arctic areas, including lingonberry (V. vitis-idaea), blueberry (V. angustifolium), and cranberry (V. macrocarpon).

            As elevation of latitude increases, the scrub brush peters out and the flora now consists of sedges, grasses, and herbs.  This vegetative zone is considered to be sedge meadows.  The flora in these meadows belongs to two major genera only.  Eriophorum and Carex, and they are very variable in species: cotton grass (Eriophorum vaginatum) is the major, single most abundant plant in the low Arctic, closely followed by a true sedge, Carex aquatilis.  As climatic conditions vary, as one moves away from the Arctic, the genus remains the same with only the species changing.
