Podocarpus species are evergreen woody plants. They are generally trees, but may also be shrubs. [1] The trees can reach a height of 40 metres (130 ft) at their tallest. [3] Some shrubby species have a decumbent growth habit. The primary branches form pseudowhorls around the trunk. The bark can be scaly or fibrous and peeling with vertical strips.
The world's tallest, thickest, largest, and oldest living trees are all conifers. The tallest is a coast redwood ( Sequoia sempervirens ), with a height of 115.55 metres (although one mountain ash, Eucalyptus regnans , allegedly grew to a height of 140 metres, [ 16 ] the tallest living angiosperms are significantly smaller at around 100 metres.
As with many Fagaceae, the nuts of many Castanopsis species are edible. The trees may be grown for their nuts, but more often they are used as forestry or ornamental trees and the nuts are collected opportunistically. Among many animals, such as tits, corvids, rodents, deer and pigs, the nuts are popular as food too.
The Douglas fir (Pseudotsuga menziesii) [4] is an evergreen conifer species in the pine family, Pinaceae.It is native to western North America and is also known as Douglas-fir, [5] Douglas spruce, [6] Oregon pine, [7] and Columbian pine. [8]
Among the animals for which live oak acorns are an important food source are the bobwhite quail, the threatened Florida scrub jay, the wood duck, yellow-bellied sapsucker, wild turkey, black bear, various species of squirrel, and the white-tailed deer. The tree crown is very dense, making it valuable for shade, and the species provides nest ...
A Global Trees Campaign project that planted 2000 trees found a 90 percent 10-year survival rate. [ 11 ] Another major threat to the survival of A. araucana , is the presence of non-native seed eating species, in particular mammals, which have been shown to severely restrict the reproduction of the tree in comparison to native seed eaters.

[7] In areas where there is a reason for being deciduous, e.g. a cold season or dry season, evergreen plants are usually an adaptation of low nutrient levels.
