Arenaria

Above this and up to the permanent snow line at about 5,750 m, plant life is restricted to lichens, mosses, dwarf grasses and sedges and alpines, such as Arenaria polytrichoides and Tanacetum gossypinum.

Species such as red knot ( '' Calidris canutus '') and ruddy turnstone ( '' Arenaria interpres '') are inferred to have had much larger populations and more extensive breeding areas during glacial stages, although others, such as dunlin ( '' C. alpina ''), exhibit evidence of range fragmentation during glacial stages leading to the evolution of distinct geographically restricted infraspecific taxa.

However, there is no doubt that mangroves of this ecoregion are crucial to several long-distance bird migrants including ruddy turnstone (Arenaria interpres), spotted sandpiper (Actitis macularia), and whimbrel (Numenius phaeopus) that utilize them as feeding and resting places from August through April during their extraordinary intercontinental journey.

Several migratory wader species are regular visitors to the island, principally are double-banded dotterel Charadrius bicinctus, eastern golden plover Pluvialis dominica, turnstone Arenaria interpres, whimbrel Numenius phaeopus and bar-tailed godwit Limosa lapponica.

These include pelts (snow leopard, wolf, serow, leopard, and black bear) and many medicinal plants, including a number of taxa like the cushion plant Arenaria spp. and the thickly tufted Saussurea spp. that come from the high alpine areas.

Some cushion plants and woolly alpine forbs like Leontopodium, Saussurea, Arenaria bryophylla, and Thylacospermum caespitosum also grow here and owe their distinctive morphology to the rigors of the alpine environment, including a short growing season, persistent winds, high potential evapotranspiration, and intense solar radiation.

Where hills extend above 5,000 m, Kobresia pygmaea and cushion plants like Arenaria, Androsace, and Oxytropis dominate stable slopes.

Kobresia meadows occur in the higher, drier locations, with cushion plants (Arenaria musciformis and Androsace tapete).

Therefore, the ecoregion boasts the record for a plant growing at the highest elevation in the world: Arenaria bryophylla, a small, dense, tufted cushion-forming plant with small, stalkless flowers, was recorded at an astonishing 6,180 m by A.F. R. Wollaston.

Godwits (Limosa lapponica baueri), knots (Calidris caanutus), and turnstones (Arenaria interpres) are the most commonly seen species.
