Trees in urban environment are of great importance for the city population due to their positive impact on the environment, mitigating numerous negative factors present in urban area. One of the most important tree care procedure for trees in urban areas is pruning. The goal of tree pruning in urban areas is development and maintenance of natural crown habitus which ensures good biomechanical characteristics and vitality of the trees. Many trees in urban areas are in unnatural state due to improperly preformed and intensive pruning procedures. Consequence of tree pruning of that kind is presence of secondary crown that does not correspond to the natural tree crown habitus. The secondary crown of the analyzed trees is divided into 3 groups depending on the number of branching levels, i.e. the degree of development of the canopy. Trees of the 1st group: these are trees with random bifurcations on two levels that were pruned or pollarded in the past, and their current secondary crown deviates from the artificial forms of the crown and tends towards the (semi) natural form of the crown by directional pruning. Trees of the 2nd group: these are trees with random forks on three levels, the crown of which, after severe pruning intensity, develops to a certain extent according to its (semi) natural shape. Trees of the 3rd group: are trees with random forks on four levels, whose crown after severe pruning intensity develops to a certain extent according to its (semi) natural shape. Two species of trees were chosen for the research: Celtis australis L. – European nettle tree and Platanus x hispanica Munchh. (Platanus x acerifolia) – sycamore, hybrid sycamore. Field research on trees with a secondary canopy was conducted in three locations: Location 1 - European nettle tree alley in Murve Street (Novigrad), location 2 - Plane trees alley in Franje Markovića Street (Križevci) and location 3 - European nettle tree alley in Kolodvorska Street and Starih Statuta Street (Pula). By comparing the trees in analyzed alleys, it is evident that, those trees where smaller branches were pruned (group 1, group 2), where the intensity of pruning was less (group 2) and which have more underground growth space have better health and better callusing of wounds. In order to preserve trees in the urban environment, it is necessary to prescribe appropriate methods for future pruning goals of such trees with an aim to develop secondary crown that is favorable for the tree, but also enables better provision of ecosystem services of the urban tree. Therefore, the shape of the tree's natural habitus determines the direction in which the long-term development of the tree with the secondary crown should go, while the goal is determined by the limitations of the current state.
