There is a possibility to protect the environment of Kosice against the menaces of mistletoe, vermin birds and emissions

In our report we deal with the possibility of protecting the environment of the city of Kosice against white mistletoe, vermin birds, and emissions. The mutual interaction of all three factors damages mainly the trees of that environment, which are located predominantly around the highways, in the city parks and on the outskirts of the city Kosice. Trees damaged by white mistletoe parasitism are not able to realize their maximum vegetation, process of growth, and the satisfactory fulfilment of the sanitary function of the environment, in particular to produce oxygen, environmental moisture, and to form shadows. Among other trees that are very sensitive are poplars, birches, willows, appletrees, and some others. The transfer of the white mistletoe from one tree to the other is, realized predominantly by such vermin birds as crows, rooks, magpies, jays, etc.
