Quercus agrifolia, the California live oak, [3] or coast live oak, is an evergreen [4] live oak native to the California Floristic Province.Live oaks are so-called because they keep living leaves on the tree all year, adding young leaves and shedding dead leaves simultaneously rather than dropping dead leaves en masse in the autumn like a true deciduous tree.

Chart illustrating leaf morphology terms The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets ). [ 1 ]
Fagus grandifolia is a large deciduous tree [6] growing to 16–35 metres (52–115 feet) tall, [7] with smooth, silver-gray bark.The leaves are dark green, simple and sparsely-toothed with small teeth that terminate each vein, 6–12 centimetres (2 + 1 ⁄ 4 – 4 + 3 ⁄ 4 inches) long (rarely 15 cm or 6 in), with a short petiole.
The leaves appear relatively late in spring, and turn a clear pale yellow in autumn. The leaflets fold together in wet weather and at night , as some change of position at night is a habit of the entire leguminous family. Young trees are often spiny, especially on root suckers and branches near the ground; mature trees often lack spines.
Quercus gambelii trees differ in size from one location to another. The average mature height is from 3–9 metres (10–30 feet), but occasionally reaches heights of 18 m (59 ft) in some locations. The average mature height is from 3–9 metres (10–30 feet), but occasionally reaches heights of 18 m (59 ft) in some locations.
Griselinia littoralis is a hardy evergreen shrub that grows up to about 10 metres tall. [2] Griselinia littoralis is round in shape and has dense foliage. The leaves are alternate, leathery, glossy yellow-green above, paler and matte below, 6–14 cm (2–6 in) long, oval with a smooth margin.
Pinus, from a Latin plant name [39] [40] [41] 11 genera, [42] scattered widely in the Northern Hemisphere [43] Evergreen and deciduous conifers, mostly trees and some shrubs, with heavily scented resin. Leaves are needle-shaped or linear. Pinus pinea is grown commercially for pine nuts. Many species are grown as ornamentals, especially for ...
The foliage is browsed by ungulates such as black-tailed deer, mule deer, elk, and horses, as well as by mountain beavers and other rodents. [ 20 ] [ 21 ] A western Oregon study found that 60% of bigleaf maple seedlings over 25 cm (10 in) tall had been browsed by deer, most several times.
