Trees make our cities more livable for a variety of reasons. However, the amount of tree canopy in our cities has been declining for many years. When large mature trees near the end of their life, they are generally replaced with lesser species, if at all. Because of the pressures of their paved surroundings, these replanted trees struggle to establish and mature.
Many cities and urban communities worldwide are beginning to improve their “green infrastructure” because they know how important it is. Therefore, planting trees in cities could bring so many benefits. Below are a few facts to help validate the importance of urban trees and why professionals need to put suitable systems to nurture them.

(i) Trees assist in avoiding water pollution by minimizing runoff and enabling water to travel down the trunk and into the land beneath the tree. This keeps contaminants from entering the ocean via rainwater. Trees work like a sponge when mulching, naturally filtering the water and recharging groundwater sources.
(ii)Trees enhance air quality by filtering hazardous dust and pollutants from the air we breathe, such as ozone, carbon monoxide, and sulfur dioxide. A mature tree alone can absorb up to 48 pounds of carbon dioxide, while trees within street proximity absorb nine times more pollutants than those planted far from each other. Research also shows that ozone is improved by 3% to 7% every time urban tree canopy increases by 10%.
(iii) Trees provide health benefits. With their capacity to secure individuals from contamination and extraordinary climate, trees accommodate those enduring asthma, skin cancer, hypertension and other stress-related ailments.

(v). Trees clean the air. Trees retain scents and toxin gasses (nitrogen oxides, smelling salts, sulfur dioxide and ozone) and channel particulates out of the discuss by catching them on their leaves and bark.
Urban trees give various benefits that make cities greener, more maintainable and more beneficial. But to require full advantage, these trees must be competent in surviving and flourishing within the urban scene where room for development is ordinarily restricted.
