Thuja hosts caterpillars of 49 species
of butterflies and moths, in some areas.

On flat wet undisturbed land, this tree typically lives 80–90 years, before falling to strong winds or its own weight, or to a fungal infection.

On cliff faces, however, this tree is very slow-growing, and can be very long-lived.  E.g., the size of a bush, after 1,000 years.
