Islamabad
is also known as the "Pollen Allergy Capital of the World". Every
year in the spring season, residents of the twin cities are afflicted by pollen
allergy and they have to adopt extra preventive measures.
The number of allergy patients goes up every year
especially during March and April. The
pollen count in Islamabad hovers above 30,000 particles per cubic meter during
the peak season. And that is not considered a record high. It regularly tops
40,000 and there have been years when it went all the way up to 55,000. In
March and early April, when the city blossoms with flowers and plants, nearly
one-third of the population is afflicted by pollen allergy.
What causes this world-record-setting
pollen count? In the 1960’s when Islamabad was being build, Broussonetia
papyrifera or Paper Mulberry, as it is commonly known was
imported and planted all over the city. The paper mulberry tree took to the climate and went wild. There are now
hundreds of thousands of trees throughout the city. Islamabad is
now a green city, as the city planners had envisioned, but most of the
vegetation is paper mulberry.
Paper Mulberry does not require any
external help to grow. You will find it growing in backyards, stream banks,
sidewalks, empty plots -- practically any open space. This non-native species
has also destroyed the native vegetation. These trees release high levels of pollen each spring.
Residents of Islamabad and Rawalpindi afflicted with
pollen allergy have been asked to adopt extra preventive measures during the
spring season when pollen count ranges highest in mid March in the twin cities.
The
main signs of pollen allergy include sneezing, running nose, itching and
watering of eyes, coughing, and difficulty in breathing.
According to Pakistan Metrological
Department the pollen concentration is higher in E – 8, F -8, G - 7 and H-8 as
these sectors have more paper mulberry trees.
There
have been drives in the past to cull this horrendous plant, but they did not
yield tangible results. It is a monster that is very hard to get rid of. But if
nothing is done, people will continue to suffer. These trees
should be chopped and can be replaced with a species that does not come with
the baggage.
