Walory przyrodnicze, stan obecny i zagrożenia wybranych alei gminy Lubin

A lot of beautiful lanes can be found in Lubin commune in Lower Silesia. Six of them, selected in the way that enables showing the trees differentiation resulting from localization, species composition and age, were analyzed. Quercus petrea, Populus x canadensis, Quercus rubra, Acer platanoides, Aesculus hippocastaneum, Tilia cordata, Tilia platyphyllos, Salix alba, Prunus avium and Alnus glutinosa were used for planting. Trees were set in one-species alleys, multi-species alleys with mixed individuals of particular species, and also in a more decorative manner, so that each of the species created a separate espalier. The most interesting one in respect of the arrangement and adaptation for performer function was a three-part lane in Liściec, regarding its decorative values - two-species (chestnut-maple) stand densely situated along the road from Chojnów to Karczowiska. Just there Acer platanoides and Aesculus hippocastaneum create separate espaliers on both sides of the road. The preservation state of plants is not the same. Cherry (in Chróstnik) and willow (in Bukowno) lines are slowly disappearing from the agricultural landscape, which is most upsetting. Well-kept lanes, where all gaps caused by falling trees are refilled up-to-date, are met relatively rare; the trees planted along the estate road to a palace in Krzeczyn Mały are such a praiseworthy exception. Not the health status of trees, but the fact that they are growing too close to roadways is the reason for anxiety as to the future of some lanes. Trees were planted along the roads which looked different than nowadays, and fitted for different road traffic. Old trees are especially amazing. For that reason, many trees that reached dimensions qualifying them as nature monuments can be found there. It is worth trying to give them legal protection, and especially care about those species that are more and more seldom found by the roads, such as cherry and willow.
