Capital battles pollen with tree overhaul
As pre-monsoon clouds gather over the Margalla Hills, another kind of storm is unfolding in the capital — one driven by chainsaws, excavators, and urgent environmental action. The Capital Development Authority (CDA) is racing to remove thousands of paper mulberry trees from Islamabad ahead of their next bloom to prevent a repeat of springtime health crises.
Islamabad, long celebrated for its greenery, is now rethinking its urban landscape. The fast-growing Broussonetia papyrifera, or paper mulberry, was heavily planted in the 1960s to shape the city's verdant image. However, the tree has since become one of the leading causes of severe seasonal allergies.
"We're not just cutting treeswe're saving lives," said CDA Environment Director Irfan Niazi. "This is one of the most important environmental health initiatives in the city's history."
Each spring, male mulberry trees release immense quantities of airborne pollen, triggering asthma attacks and allergic reactions in thousands of residents. According to the Pakistan Institute of Medical Sciences (PIMS), over 12,000 allergy patients are treated annually due to mulberry pollen, with emergency rooms reporting a 30% spike in asthma cases.
"If we don't remove a critical number of these trees before the next flowering cycle, we'll face another health disaster next year," said Akhtar Rasool from CDA's Horticulture Department.
The CDA's tree removal drive, launched last year, has entered an accelerated phase. Targeted operations are underway in sectors such as G-6, G-7, F-6, and F-8, where the density of mulberry trees is highest. Each tree is GPS-tagged, assessed for size and location, and only male trees are removed. Removal activities are being documented for transparency.
Work crews, clad in safety gear, operate daily to cut, chip, and transport the trees. The campaign is supported by traffic and safety teams to maintain public order and protect infrastructure.
Critically, for every tree removed, the CDA is planting at least 10 native, low-allergen species such as phulai (Acacia modesta), amaltas (Cassia fistula), sukh chain (Dalbergia sissoo), and wild olive (Olea ferruginea). These species support biodiversity, provide shade, and do not release harmful airborne pollen.
"These trees are either insect-pollinated or produce heavy pollen, making them safer for public health," said CDA botanist Rana Kashif. He added that CDA nurseries are cultivating over 100,000 saplings this year, with mass plantation planned during the monsoon season.
At Polyclinic Hospital, where allergy cases have surged for years, Medical Officer Dr. Swaira welcomed the move. "We've seen patients develop chronic asthma from repeated exposure. With these removals, we hope for a measurable decline in cases by 2026."
Hospitals like PIMS and Polyclinic have established dedicated allergy clinics, expanded emergency capacity during peak pollen months, and are coordinating with CDA to monitor health impacts.

During his visit to the Federal Government Polyclinic Hospital and the Pakistan Institute of Medical Science (PIMS), the minister directed fast-tracking of cancer hospital construction with increased workforce and double shifts. In a decisive move to enhance diagnostic capacity, Kamal instructed the immediate installation of an MRI machine at Polyclinic Hospital. He reiterated his commitment to ensuring the provision of quality healthcare services to the public at all costs, stating, "Access to timely and quality medical care is a fundamental right of every citizen." During the visit, Kamal ordered comprehensive feasibility and master plan for old Polyclinic hospital building upgradation with modern Heating, Ventilation and Air Conditioning (HVAC) system integration. During the visit, the minister was accompanied by Federal Secretary of Health Syed Waqarul Hassan. The visit was aimed at reviewing healthcare facilities and service delivery at one of the capital's key public sector hospitals. The health minister conducted a thorough inspection of all hospital departments and evaluated the services being provided to the patients. He visited the medical wards, Intensive Care Unit (ICU), and dialysis centre, where he received briefings on the current infrastructure and operational status. The executive director of Polyclinic provided a detailed presentation on the hospital's facilities and areas requiring immediate improvement. While acknowledging the efforts of the staff, Mustafa Kamal directed that 20 additional beds be added to the dermatology and psychiatry departments located at G-7/3-4 to cater to the growing patient load. He also ordered the development of a comprehensive feasibility plan for upgrading the old building of Polyclinic Hospital, incorporating a modern HVAC.

NA body finds fault with hospitals lease
A parliamentary panel has called for reviewing the lease granted to big hospitals in the federal capital, stating that there is a need for the Capital Development Authority (CDA) to sign new agreements with the medical institutions in view of public interest. The National Assembly Sub-Committee for Health convened on Monday. During the meeting, the convener, MNA Amjad Khan, stated that the CDA has provided all relevant documents with regard to land leased to major hospitals in Islamabad. The convener suggested that all such lease agreements should be reviewed and renewed in the public interest. According to CDA laws, any agreement can be revised or canceled, he said. He said the Shifa International pays taxes to the Federal Board of Revenue (FBR) and also enjoys certain exemptions while it holds a lease valid until 2052. He said if this lease was signed in 2019, the committee wants to know under what terms it was done. Committee member Shazia Sobia stated that plots were allocated to the health institutions on a social, not commercial, basis, yet the leases were revised blindly. The convener proposed referring the issue to the Public Accounts Committee especially since leases were revised without thoroughly checking the status of services provided. Member Sabin Ghori raised a concern about Shifa International building parking on a green belt, asking the CDA for clarification. The CDA DG Land responded that only the directorate of municipal administration (DMA) could answer that. The convener stated that under Rule 227, the committee could request data from the FBR. "Until we have the data, we cannot reach a conclusion," he said. However, the FBR representative replied that sharing taxpayer data could create legal issues for him. Committee members then raised questions about the chairman and members of the Islamabad Healthcare Regulatory Authority (IHRA) board, arguing that if a private hospital owner chairs the board, it would result in a conflict of interest. The IHRA CEO told the panel that the board consists of seven members and two positions from the federal government remain unfilled. The Ministry of Health can provide more information on how board members are selected, he said. The convener asked how someone who owns a hospital and a medical college could serve the public interest while holding such a powerful position. He said the board has held only one meeting to date.
