The inventory carried out in the 19th century historic park in Swadzim near Poznań recorded the total of 1886 trees, bushes and climbers deriving from 64 species. At the present time, the park is neglected and a plan for its revalorization is badly needed. Tree composition is dominated by Quercus robur, Robinia pseudoacacia, Acer pseudoplatanus, Carpinus betulus, Q. rubra and Fagus sylvatica, while that of bushes – by Sambucus nigra. The height of trees ranges from 16 to 20 m and their circumferences – from 45 to 114 cm; the health condition of the majority of trees is good or even very good. Single specimens of rare and threatened species were found to occur. The total of 101 splendid trees from 26 taxons were inventoried among which A. pseudoplatanus, A. platanoides, Aesculus hippocastanum, R. pseudoacacia and C. betulus dominated. In comparison with the Rataj’s inventory from 1976, transformations are apparent in the dendroflora of the park towards its naturalisation. The tree stand requires cutting and tending intervention.
The research presented in this paper concerns the diversity and spatial structure of town green areas. Its goal was to compare the dendroflora of the “Wschód” estate in Świdnik with similar urban architectural complexes that have been analysed thus far. The purpose of this research was also to compile an inventory and to determine the species diversity of trees and shrubs that grow within the estate, as well as to indicate their composition and spatial function.
This paper presents the results of a detailed inventory of the historic manor park in Łęczna in the Lublin Voivodeship, conducted in the year 2011. This object is an example of combining elements of the eighteenth-century Italian garden with the nineteenth-century landscape park. The park area is 12 hectares. A user of the area is the King Casimir School. A detailed dendrological inventory of the park revealed 932 items, including 852 trees and 25 large groups of shrubs. Tree stand of the park in Łęczna is represented by 32 species and varieties of trees. In terms of numbers prevail: Tilia cordata Mill., Acer platanoides L., Fraxinus excelsior L., Carpinus betulus L. and Robinia pseudoacacia L. Rare species of the foreign origin are Acer platanoides ‘Schwedleri’, Acer saccharinum ‘Wieri’, Cladrastis lutea Rudd., Gleditsia triacanthos L., Platanus ×hispanica ‚Acerifolia’, Quercus macrocarpha Michx. and Pinus nigra J. F. Arnold. The possibilities and directions of restoration presented in this work are based on the collected data.
The article presents the composition of the dendroflora in a historic park surrounding the castle in Szamotuły. In total 465 specimens of woody plants were inventoried (51 taxa of 37 species in 21 families). Most of them were native, angiospermous trees of the apophyte and spontaneophyte groups. In the park there are three specimens of Taxus baccata, registered as natural monuments. The age of more than 100 trees was estimated at over 100 years. The trunk circumference of more than 60 trees exceeded the minimum value assumed as a criterion of categorisation as a natural monument.
The occurrence of polyprenols in leaves of over 340 species of dendroflora in natural habitats in the regions of Hanoi and Hue in Vietnam was studied. Plant material was collected in the late autumn (October/November) during the end of a vegetation season. Leaves of about 200 plant species did not contain detectable amounts of polyprenols in contrast to few systematic families, e.g. Moraceae,Euphorbiaceae, where polyprenols were highly abundant and their pattern could be used as a chemotaxonomic criterion. Most often dominating polyprenols were prenol-11 and prenol-12. In several angiosperm species prenol-13 and detectable amounts of prenol-14 were also found. The incidence of prenol-13 and -14 was not restricted to a specific taxonomic group since species exhibiting domination of such longer chain polyprenols belonged to various systematic families. In some plants (e.g. Ceiba pentandra) α-cispolyprenols were accompanied by α-transcounterparts. This report describes several new plant species that may serve as natural sources of long chain polyprenols
In order to understand the environmental variables that may impact more on the distribution of species of trees and shrubs, a correlation analysis applying the Covariation (C) of Gregorius was conducted among 14 variables of climate and physiography, and the number of individuals of 72 species, which were found in 1804 sampling plots (covering about 123,317 km²) of the National Forests and Soils Inventory (INFyS) developed by the National Forest Commission in Mexico (CONAFOR). Among the studied species there are several of the genera Quercus, Pinus and Junniperus, which are mainly distributed in the Sierra Madre Occidental, where they stand out for their abundance. The results show that the density of 88% of the studied species have a significant correlation (P <0.025) with at least five of the 14 variables analyzed. Seven of the variables showed significant correlation (P <0.025) with at least 74% of the studied species: ‘Julian date of last spring frost’ with an average value of covariation (C) equal to 0.71, ‘average duration of the frost-free period’ with average value of C = 0.71’, degree days above 5℃’ with covariation of 0.69, ‘altitude above sea level’ with C = 0.66; ‘mean temperature in the coldest month’, ‘mean temperature in the warmest month’ and ‘mean annual temperature’, with average values of C = 0.65 for each of these last three variables. The ‘geographic orientation of the ground’ was the least correlated with the density of the species, since only 10% of them showed significant correlation with this variable.

Ex-manor parks of the Slowinskie coast

72%
This paper presents results of a field studies in ex-manor parks of Słowinskie Coast which were made during two vegetation seasons, from May2004 to September 2005. The studies covered six ex-manor parks located in the communes of Darłowo, Sianów, Ustka and Wicko. Two of them were entered into the register of monuments (Bukowo Morskie, Osieki Koszalinskie II) and four of them were in evidence (Gabino, Machowino, Machowinko, Szczenurze). The main purpose of research was to the current status of presevation of the chosen ex-manor parks of the Słowinskie Coast and especially taking into consideration the most precious specimen of dendroflora. Many old trees, trees alleys, trees lines, foreign dendroflora taxa and protected herbaceous plats were found on the parks’ areas. The most precious specimens are: protected trees of Taxus baccata L., from Machowinko and Szczenurze; Aesculus pavia L. and Castanea sativa Mill. from Szczenurze; Liriodendron tulipifera L. from Gabino and Machowino; Fagus sylvatica L. ‘Purpurea’, Tilia cordata Mill. from Bukowo Morskie. Herbaceous plants under full and partial preservation are: Galanthus nivalis L., Leucoium vernum L., Ononis spinosa L. and also creeper Hedera helix L.
Dendroflora of Złakowo Park comprises 36 taxons. The total of 1465 trees was inventoried. The dominant tree species in the park are those associated with the communities of fertile broad-leaved forests. Trees of Carpinus betulus are the most numerous, whereas common species include: Fagus sylvatica, Fraxinus excelsior and Quercus robur. The total of 203 trees was classified as valuable of which 77 trees were included in the group with monumental circumferences, 35 trees – were classified as trees with circumferences close to monumental and 91 trees – as splendid. Trees which frequently attained considerable circumferences comprised: Carpinus betulus, Quercus robur, Fagus sylvatica, Alnus glutinosa, Fraxinus excelsior and Acer platanoides.
