Trees are natural filters, as they are able to absorb toxic substances, which are so abundant in the urban atmosphere. Bringing great benefits to the city and its inhabitants, decorating courtyards, city streets, sometimes trees become unpredictably dangerous both for the life and health of people, and for the preservation of personal and public property intact. The "lungs" of the city require special attention to themselves.
Danger of falling big trees in the city
Lingering dry trees are very dangerous for the inhabitants of the city. Especially during a riot of elements - squally winds, thunderstorms, hurricanes, when they can collapse right on people, cars, roofs of multi-storey buildings, power lines. The weight of an average tree is 2-4 tons. If it falls, it can destroy a house, and any other building to the ground. Even with a sufficiently low wind force, a branch can break off a tree, fall and injure a passing person, and for a child this can be a mortal danger.
A large dry tree always carries a potential danger, since at any time, especially in inclement weather, it can damage nearby objects or cause human death.
Falls of large trees on power lines have serious consequences. They can not only cause damage to property, but also often lead to power outages, fires and other negative consequences.
The weight of the broken tree can sag the wires while continuing to conduct electricity. Such cases pose an additional threat. If the dangerous tree has not yet fallen, but only hung over the wires, then such a situation must be eliminated as an emergency.
Which trees are the most dangerous
Trees with a crown of more than five meters should be planted at a distance of at least 10 meters from the foundation of the house and pruned every year. Dangerous trees that carry a real threat include, first of all, dry, rotten and tilted trees - especially dangerous trunks with a slope of 5 meters, located at a distance of less than 5 meters from a house or any building, as well as those trees whose root system is damaged, or having large mechanical damage.
Very often, the trees that grow next to the house interfere with the passage of daylight into the apartments, huge crowns obscure the windows.
Many plants, especially birch, spruce, pine and aspen, need constant and regular pruning, as these species can create a danger in the city in windy weather. Overgrown tree roots can destroy the asphalt and sometimes the foundation of a building.
Regular sanitary felling is necessary to ensure that the streets and parks of cities are not only well-groomed, but also safe.
