[citation needed] Oil of Thuja contains the terpene thujone which has been studied for its GABA receptor antagonizing effects, with potentially lethal properties. [26]
The inland rainforest patches are habitat for a variety of tree species. Probably the first species to colonize the northern regions after the last deglaciation was the lodgepole pine (Pinus contorta). The oldest stands however are usually dominated by western red cedar (Thuja plicata), which are also the oldest individuals in these forests. [17]
For some of these species, age estimates have been made on the basis of extrapolating current growth rates, but the results are usually largely speculation. White (1998) [105] proposes a method of estimating the age of large and veteran trees in the United Kingdom through the correlation of a tree's age with its diameter and growth character.
It is by far the largest species of spruce and the fifth-largest conifer in the world (behind giant sequoia, coast redwood, kauri, and western red cedar), [3] and the third-tallest conifer species (after coast redwood and South Tibetan cypress). The Sitka spruce is one of only four species documented to exceed 100 m (300 ft) in height. [2]
