The black poplar grows in low-lying areas of moist ground [Black Poplar. The Woodland Trust. Retrieved July 12, 2014] Ecology: Poplar can be called a record holder for environmental benefits. The broad and sticky leaves of this tree successfully retain dust, filter the air. In addition, the poplar is growing rapidly, actively gaining green mass and moistens the air around it. Oxygen, which allocates one adult tree per day, is enough for breathing 3 people during the same time. A particular advantage of poplar is its unpretentious and resilient. It survives along highways and close to fuming factories.
