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 ...
Quercus douglasii, known as blue oak, is a species of oak endemic to California, common in the Coast Ranges and the foothills of the Sierra Nevada. [4] It is California's most drought-tolerant deciduous oak, [5] and is a dominant species in the blue oak woodland ecosystem.
The flora are arranged in several sublists with different organizations for the convenience of encyclopedia users with different purposes - alphabetically by scientific name, alphabetically by plant family then by scientific name, by growth pattern (e.g., tree, shrub, perennial, annual, etc.) then alphabetically by scientific name, by flower ...
It typically is multi-trunked, with a crown as broad as it is high. Trees are long lived, with an estimated lifespan between 250–280 (300 maximum) years. The leaves are dark green, palmately compound with five (rarely seven) leaflets. Each leaflet is 6–17 cm (2.4–6.7 in) long, with a finely toothed margin and (particularly in spring ...
The dominant trees are oaks, interspersed with other broadleaf and coniferous trees, with an understory of grasses, herbs, geophytes, and California native plants. Oak savannas occur where the oaks are more widely spaced due a combination of lack of available moisture, and low-intensity frequent fires .
In cooler, more exposed areas, scrub oak is usually a small, compact shrub, but in warm or sheltered areas the plant can spread out and grow several metres high. [ 4 ] It has oval to egg-shaped, sharply toothed, dull green leaves which are 1.4–3 centimetres ( 1 ⁄ 2 – 1 + 1 ⁄ 8 inches) long [ 3 ] and 1–2 cm ( 1 ⁄ 2 –1 in) broad ...
It is reduced to a shrub in extreme dry and hot habitats. [3] During the Miocene, oak-laurel forests were found in Central and Southern California. Typical tree species included oaks ancestral to present-day California oaks, and an assemblage of trees from the laurel family, including Nectandra, Ocotea, Persea, and Umbellularia.
