There has
been much speculation over the health risks associated with Plane Trees
particularly at this time of year and last Sunday’s wind and pollen event was
the last straw for those traders who are particularly allergic to airborne
irritants.
Of course
customers are also impacted and when our market is surrounded by Plane Trees,
including those on our doorstep in Queen St. the problem is magnified.
Apparently not everyone is affected by Plane Trees, in fact the population is
less likely to be affected by these trees than say Rye Grass, but when the
pollen and irritating fibres accumulate like they did last Sunday, the impact
can be severe. Our photo overstates the level of pollen and fibres but the need for face
masks was very real.
In a report a few years back, Sydney
academic, Professor Euan Tovey, said - “that while plane tree pollen doesn't cause as many
allergies as most people presumed, their trichomes were a powerful irritant.” ''Those white hairy things,'' he said, pointing at
microscopic fibres on the back of the plane tree's leaves, ''are very sharp.
They're trichomes. They come off and float off in the air. '' The report said that “more research was needed
but it was very likely it was the trichomes that were causing the bulk of the
problems, especially given intense exposure could make symptoms worse. That
could explain why arborists often complained about plane trees. Another problem was the trichome season, running
for about 12 weeks from September to November, was twice as long as the pollen
season for six weeks from late August.”
Another report said – “Last year complaints from members of the public and
business owners on Melbourne's popular Lygon Street coffee strip prompted the
local council to trial hormone injections and sprays to try to reduce the
amount of pollen the trees produce. It had little impact, so some Melbourne and
Sydney councils have opted to phase out plane trees altogether.”
We understand that CoM have a policy of replacing
damaged Plane Trees with other varieties but maybe they need to be more
pro-active, at least around Queen Victoria Market where such a large number of
people are gathered in a small area. A deliberate cull of let’s say 100 PlaneTrees
per year should be manageable in the city budget.

They are the curse of Melbourne city. No wonder Melbourne has been found to be the worst city in the world for allergic seasonal ailments." Andy
Thanks for your input Andy. It is a good time for replacements to be installed.- Ed
