Description:
Alpine plants are plants that grow in the alpine climate, which occurs at high elevation and above the tree line. Alpine plants grow together as a plant community in alpine tundra.

Alpine plant diversity

Relative to lower elevation areas in the same region, alpine regions have a high rate of endemism and a high diversity of plant species. This taxonomic diversity can be attributed to geographical isolation, climate changes, glaciation, microhabitat differentiation, and different histories of migration or evolution or both. These phenomena contribute to plant diversity by introducing new flora and favoring adaptations, both of new species and the dispersal of pre-existing species. Common plant life-forms include prostrate shrubs, graminoids forming a tussock, herbaceous perennial plants, cushion plants, and cryptogams, such as bryophytes and lichens.

Adaptations

Surviving low temperature extremes

Most alpine plants are faced with low temperature extremes at some point in their lives. There are a number of ways that a plant can survive these extremes. Plants can avoid exposure to low temperature by using different forms of seasonal phenology, morphology, or by variable growth form preference. They can also avoid the freezing of their exposed tissues by increasing the amount of solutes in their tissues, known as......
