Shrubs and herbs are usually sparse, but can be common in stands where snow melts earlier in the growing season. Diversity of herbs in the subalpine zone is usually less than lower-elevation zones such as upper and lower montane. Broad classifications of herb and shrub communities can be found in Sawyer and Keeler-Wolf. [7]
For example, Seattle, Washington, and the city of Austin, Texas, are both in the USDA hardiness zone 9a because the map is a measure of the coldest temperature a plant can handle.
The lowest-elevation biotic zone in the Sierra Nevada is found along the boundary with the Central Valley. [5] This zone, stretching in elevation from 500 to 3,500 feet (150 to 1,070 m), is the foothill woodland zone, an area that is hot and dry in the summer with very little or no snow in the winter. [5]
The climate of California varies widely from hot desert to alpine tundra, depending on latitude, elevation, and proximity to the Pacific Coast. California 's coastal regions, the Sierra Nevada foothills, and much of the Central Valley have a Mediterranean climate , with warmer, drier weather in summer and cooler, wetter weather in winter.
Alpine plants often have gray appearance from hairs covering the leaves, which reflect the intense sunlight, and protect from winds that cause high rates of water loss through transpiration. [4]: 224 Many Sierra Nevada alpine plants have reddish or whitish leaves to protect them from damage from intense ultraviolet radiation in the alpine zone.
Chaparral (/ ˌ ʃ æ p ə ˈ r æ l, ˌ tʃ æ p-/ SHAP-ə-RAL, CHAP-) [1] is a shrubland plant community found primarily in California, southern Oregon, and northern Baja California. It is shaped by a Mediterranean climate (mild wet winters and hot dry summers) and infrequent, high-intensity crown fires .
California is in one of the world’s 36 biodiversity hot spots and is home to more than 6,000 types of native plants, including hundreds of wildflower species. Only a few other places on Earth ...
Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.
