Coniferous trees in the "Nicolae Titulescu" Park in Brașov.
In the Titulescu Park, governed by the temperate-continental climate and by the topoclimate specific for regions located at mountain foots (Rom. "Topoclimat piemontan") and intra-mountain valleys, the vegetation state of the 18 coniferous species, of which 12 exotic species, is unsatisfactory. The topping works done for the formation of the canopy structure are of low quality and done in an inconsequent manner. Out of 108 Taxus baccata specimens, only a few made the object of pollarding and thinning works, the rest of them being left in the understory, sprouting and branching in a for the vegetation state detrimental way. Such specimen are surely not going to reach the potential lifetime of 2000-3000 years characterising the Taxus baccata specimen in good health. Thinning works are being neglected. Thuja plicata has some specimen covered by birch, beech and magnolia trees. Chamaecyparis is left in the understory, dominated by Styphnolobium japonicum, Acer platanoides, Pinus nigra or Prunus cerasifera var. pisardi. In the high-density groups of Picea pungens, Chamaecyparis losses some of its typical silver colour. Pseudotsuga menziesii cannot reach its potential growth in height and basal area because of the shading by Styphnolobium japonicum. Three of the Picea pungens have their tops cut off as Christmas tree. One of the two specimens of the Cryptomeria japonica is underdeveloped under the canopy of an Acer negundo and a Pinus nigra tree. Besides hedges kept in good condition, there are also wild badly maintained hedges. Among the greatest impediments that hinder a good vegetation state of coniferous trees in the Park are: an excess in Na, Cu, Ca, Cl, S, Mg and an deficiency in P, K, Mn, N. Finally, it is recommended to introduce an individual record for every tree, a monitoring of the pollution and of the nutritional state, individually chosen measures of protection against pests before felling of wounded specimens.
