Silver birch Betula pendula is a characteristic tree with a white trunk and a light, airy crown. It is a native species, growing on dry and sandy soils, also as a pioneer plant in degraded areas, and can grow to a height of 30 m and live about 100 years. The birch is a wind-pollinated plant and blooms in April. Alleys of trees, as well as single trees in the agricultural landscape, perform many important functions (we encourage you to check the educational boards at the Station). One of them is lowering the temperature of the air while increasing its humidity. This happens due to evaporation (transpiration) of water from the surface of leaves, and the amount of such evaporated water per day may reach several hundred liters.
