Flying catkins that cause discomfort and fire hazards during spring, have been spotted in the central and southern parts of Beijing, as the city government announced the beginning of this year's catkin season on Sunday.

The Beijing Municipal Forestry and Parks Bureau and the city's meteorological service forecast that the northern districts will see catkins from Monday.
The catkins look like cotton clusters with seeds wrapped in fabric. While blowing about, the catkin seeds fall to the ground, where they will germinate and become new trees.
Even though willows and poplars are common ornamental trees in many regions, their catkins have become somewhat of a menace. Too many catkins can increase the risk of fire as they are very flammable. The floating catkins can also affect the air quality. They are also a nuisance for urban residents who have allergies.

Three high-incidence periods of poplar and willow catkins have been predicted in mid-April, late April to early May, and mid-May, affecting downtown areas as well as mountainous regions of the capital.
The public has been urged to wear dust masks, sunglasses, goggles or scarves to block flying catkins.
