In southern Florida, the pollen was suspected to cause serious allergic reactions and acute respiratory problems (Geary, 1988), though detailed studies proved that M. quinquenervia is not a significant source of aeroallergen and M. quinquenervia odour is not a respiratory irritant (Stablein et al., 2002). 10, 109-127.

Spotted gum is a tall tree with a straight trunk, growing up to 45 metres in height, or sometimes taller. M. quinquenervia in New Caledonia occurs extensively on well-drained slopes and ridges in the uplands, as well as on marshy plains (Gillison, 1983). The best-developed stands of M. quinquenervia occur as open-forest or woodland on favourable sites, but elsewhere are reduced to low woodland or tall shrubland. Not all herbicides work in the same way, and some trees are resistant to certain herbicides. Call a professional for stump and root removal if you do not have experience in the use of stump grinders or if the sweetgum tree is too large for successful removal with a small grinder.
