Cypress Trees, Allergic Reactions, and the City's Response

Beijing's Cypress Trees and the Pollen Problem

In Beijing, videos of large whirls of pollen being blown into the air from cypress trees have sparked widespread discussion. With pollen concentrations reaching high levels, many residents are concerned about the potential for allergic reactions.

The Temple of Heaven Park, home to 33,000 cypress trees, has witnessed strong winds causing large amounts of yellow pollen to scatter like a sandstorm. This phenomenon is attributed to the trees' natural reproductive cycle, combined with dry air and scarce precipitation.

Meteorological authorities have warned that the high pollen concentration is likely to cause allergic reactions, advising people to reduce outdoor activities and take necessary precautions. Many residents have reported symptoms such as sneezing, runny noses, and itchy eyes.

While some social media users have suggested cutting down cypress trees, experts argue that this is not a feasible solution. Cypresses are native to Beijing, offering low cost, easy maintenance, and high survival rates. They are also essential to the city's urban environment.

Instead of removing the trees, the city has implemented pollen control measures. This includes spraying water on cypress trees in key parks and forest areas to reduce pollen concentrations. Additionally, the city has revised its tree planting catalog, pledging to plant female cypresses that do not release pollen in future landscaping projects.

To prevent pollen allergies, residents are advised to limit outdoor activities, especially during peak pollen times. Wearing masks, glasses, and long-sleeved clothing can also help reduce exposure to pollen.

By implementing these measures, Beijing aims to address the pollen problem while preserving the city's valuable cypress trees.
