At global, national and regional government scales, many Guioa species have been threatened with extinction, as officially recognised by the
International Union for Conservation of Nature (IUCN) and by continental, national and local governments. Twenty five species, or more, have official IUCN global conservation statuses of either "critically endangered", "endangered" or "vulnerable" (to global extinction).
The Australian species are known to the
logging industry as cedars, though they have no direct relationship with true
cedars or the Australian members of the
Meliaceae which are known as cedars.
