Cypress is any of the twelve species of ornamental and timber evergreen conifers constituting the genus Cupressus of the family Cupressaceae.Many resinous, aromatic evergreen trees called cypress belong to other genera of the same family, especially species of false cypress and cypress pine.
The conifers, division Pinophyta, are one of 13 or 14 division level taxa within the Kingdom Plantae. They are cone -bearing seed plants with vascular tissue; all extant conifers are woody plants , the great majority being trees with just a few being shrubs .
Giant sequoia. Silvics of North America (1991), [1] a forest inventory compiled and published by the United States Forest Service, includes many conifers. [a] It superseded Silvics of Forest Trees of the United States (1965), which was the first extensive American tree inventory. [3]
Araucariaceae is a family of conifers with three living genera, Araucaria, Agathis, and Wollemia.While the family's native distribution is now largely confined to the Southern Hemisphere, except for a few species of Agathis in Malesia, it was formerly widespread in the Northern Hemisphere during the Jurassic and Cretaceous periods.
The heartwood, bark and leaves are the tree parts richest in terpenes. [40] Some of these compounds are widely distributed in other trees as well, and some are typical for Cupressaceae family. The most known terpenoids found in conifers are sesquiterpenoids, diterpenes and tropolones. Diterpenes are commonly found in different types of conifers ...

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.
