Winds can be high throughout the year and are a major factor limiting plant growth near the upper limit of the subalpine zone (tree line). Wind limits vegetative growth chiefly in two ways: by physically battering plants, including blowing snow and ice, and by increasing evapotranspiration in an environment that is already water-stressed.

The alpine zone, or alpine fell-field, is above the tree line, generally at 11,000 to 11,500 feet (3,400 to 3,500 m) in the south, [4] [5]: 8 and 9,900 feet (3,000 m) [6]: 17 to 10,500 feet (3,200 m) [4] in the north. The plants are influenced by having to endure long and very cold winters, poor to no soils, constant high winds, intense ...
The Sierra Nevada are home to half of the vascular plant species of California, with 400 species that are endemic to the region. [16] Like many mountain ranges, the plant communities of the Sierra group into biotic zones by altitude, because of the increasingly harsh climate as elevation increases. [19]
Tree planting costs alone would cost around $1.5 billion. It’s also a race against the clock. Each year after a fire burns through an area, it becomes more costly and challenging to put trees ...
Of California's total plant population, 2,153 species, subspecies, and varieties are endemic and native to California alone, according to the 1993 Jepson Manual study. [4] This botanical diversity stems not only from the size of the state, but also its diverse topographies , climates, and soils (e.g. serpentine outcrops ).
