Trees in the City
Why do we need trees in the city? A higher number of trees in Bratislava means a higher quality of life.
They mitigate the heat in summer
The number of trees planted also affects the microclimate. In summer, trees provide shade and cool their surroundings better and more efficiently than any air conditioner, preventing asphalt and concrete surfaces from overheating. The temperature measured under the trees can be as much as 30°C cooler than in the surroundings. In the night, however, the temperature can be 3 degrees higher.
They create a more beautiful and pleasanter environment
They improve the environment and provide natural scenery that can calm us down and lift our spirits. At the same time, trees in the city provide a closer contact with nature and enable life such as birds, insects or mammals to come into the city.
They improve air quality
They act as a filter that binds dust, sulphur and nitrogen oxides, carbon monoxide and other pollutants in the air. In cities, deciduous and coniferous trees trap up to 27% and 28% of dust respectively.
They mitigate the effects of torrential rains
Trees retain water in the surrounding area during heavy rains and prevent street flooding. They bind water in the soil with their roots. They function like a sponge, absorbing water when it rains and then slowly releasing it again.
They reduce noise levels
Trees and shrubs also act as a noise barrier. A 10 m wide line of trees reduces noise by 1-6 dB.
They increase biodiversity
They are the bearer of different life forms - birds, mammals, insects and others.

Greenery Planting Map
On the map you can find information about where specific types of trees are planted, or who supported this planting as part of the 10,000 trees initiative. The tree planting map is full of greenery, and not just any greenery. Each of the most planted types of trees has its own assigned color.
