Beyond the tree line, trees cannot tolerate the environmental conditions (usually low temperatures, extreme snowpack, or associated lack of available moisture). [1]: 51 The tree line is sometimes distinguished from a lower timberline, which is the line below which trees form a forest with a closed canopy. [2]: 151 [3]: 18
Tule fog is a radiation fog, which condenses when there is a high relative humidity (typically after a heavy rain), calm winds, and rapid cooling during the night. The nights are longer in the winter months, which allows an extended period of ground cooling, and thereby a pronounced temperature inversion at a low altitude.
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 ...
Several majestic palm trees that usually flank the Refugio State Beach just north of Santa Barbara have come crashing down in recent days. Images show how the massive, 100-year-old trees were ...
Deciduous Shrubs and Small Trees: Some patio plants or trees that drop their leaves can be brought indoors for the winter. Place them in an area such as a unheated basement or garage.
Laurel forests occupy the humid tropical highlands of the Malay Peninsula, Greater Sunda Islands, and Philippines above 1,000 m (3,300 ft) elevation. The flora of these forests is similar to that of the warm-temperate and subtropical laurel forests of East Asia, including oaks ( Quercus ) , tanoak ( Lithocarpus ) , chinquapin ( Castanopsis ...
In early 2021, a potent combination of dry weather and a warming climate have produced fuels — grasses, shrubs, and trees — that can ignite in winter. Though the relatively small wildfires ...
Platanus racemosa is a species of plane tree known by several common names, including California sycamore, western sycamore, California plane tree, and in North American Spanish aliso. [1] Platanus racemosa is native to California and Baja California , where it grows in riparian areas, canyons , floodplains , at springs and seeps , and along ...
