The positive impact of trees on the Earth's climate, and on the condition of the biosphere as a whole, cannot be underestimated. Even in the smallest park, trees create shade on hot summer days and create an attractive sight with their fresh green leaves in spring and summer, and their warm yellows and reds in autumn. Their leaves help to clean the polluted city air, while their trunks and roots protect the ground from erosion, gather moisture and accumulate nutrients.
In windy weather, people feel comfortable and protected in the park, as the trees provide shelter from the gusts.
Walking through a park under the trees after rainfall can ease stress, while an evening stroll in the soothing, healing air guarantees sound and calm sleep.
Trees help us, but they also need our help:
- Every tree species requires certain environmental conditions for survival. Trees growing in a park often live in conditions far from their natural environment. They are affected by air pollution, acid rain, soil compaction and trampling, and even direct physical damage.
- Young trees require special care. During dry spells they need to be regularly watered, the ground around the trunk must be kept clear of weeds, and the soil around the roots must be enriched with nutrients (preferably organic fertilisers).
- Smaller trees may not always be noticeable. To prevent them from getting damaged, they should be protected by ornamental fences.
- The leaves of trees in big city parks can accumulate large quantities of toxins, so fallen leaves should be cleared from the park to protect the trees from disease.
- Removing dry branches will prolong the life of old trees and will help to preserve their attractiveness.
