Above the tree line, extreme winds preclude tree-like growth. [6]: 17 Constant winds hitting the plants limits their size and flattens their shape. [10]Small size or dwarfism is therefore an adaptive feature to the extremes, and most alpine plants are just a few inches tall.
Some plants with a broader altitudinal range are found listed in their predominant habitat elevation. All the plant species listed are native to the Sierra's foothills, valleys, and mountains. In addition some are also endemic to here and elsewhere within California – (ca-endemic) ; and some are further endemic to and only found in the Sierra ...
Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. There are many different plant species and taxa that grow as a plant community in these alpine tundra. [1] These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [2]
The herbaceous plants need to flower and produce their seeds quickly during the short, frost-free period of summer. [3] Flora includes cushion plants , grasses, willows, and sedges . [ 9 ] The macrolichen flora in the Sierra Nevada alpine zone is not well developed as compared to neighboring alpine zones in the Rocky Mountains and mountains of ...

The soil there is frozen from 25 to 90 cm (10 to 35 in) down, making it impossible for trees to grow there. Instead, bare and sometimes rocky land can only support certain kinds of Arctic vegetation, low-growing plants such as moss, heath (Ericaceae varieties such as crowberry and black bearberry), and lichen. [6] [7]
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.

[1] [2] Like other mountains, the Appalachians have high rates of endemism because they create isolated "islands" of unique habitat conditions distant from other, similar habitats. The high elevations of the Appalachians functioned as refugia at the end of the last ice age , and house many relict taxa that were more widespread in Southeastern ...
