In consideration of the geographical position of Samobor and its environs
where the parks are situated — and with regard to the ecological characteristics


i. c. the climate, soil and natural vegetation cover — there were found different
exotic species at a dendrological inventorying. These species are of scientific
interest for botany, silviculture, horticulture and landscape gardening, as well
as regarding recreation, tourism and cultural history.
When planting the exotics belonging to the coniferous and broadleaved tree
species and shrubs, we should primarily take into account the mosaic of the
sites in the town and environs of Samobor as well as the biological characters
of each individual species. On the basis of his observations and experience so
far, the author considers it necessary to carry out a certain grouping of individual
exotic species according to their adaptability and possibility of growing at Samobor
and its environs. In this connexion attention should be paid that each of the
exotic species is to be planted and grown on the soil exhibiting the highest number
of favourable factors for the thriving of the respective species.


Therefore the author classified the most important coniferous and broad-
leaved exotic trees and shrubs into several groups.


In the area of parks, of Samobor there occur according to a dendrological
inventorying a total of 152 species, varieties and forms, of which conifers number
45, and broadleaved species 118. Considering the source of the species in question
their share is as follows:


Coniferous trees include 38 species, of which: 12 from North America, 1U
were obtained through improvement, 9 from Asia, 4 from Evrope and Asia Minor.
Coniferous shrubs include 7 species, of which: 4 from Asia and 3 from Europe.


Broadleaved trees comprise 55 species, of which: 19 from North America, 19
were obtained through improvement, 9 from Asia, 4 from Europe, and 4 from
Asia. Broadleaved shrubs contain 48 species, of which: 23 from Asia, 9 from North
America, 8 were obtained through improvement, 2 from Eurasia, 1 from Europe,
1 from South and North America, 1 from Europe and Asia Minor, and 1 from
circumboreal species.


For forestry and forest practice these various different species, varieties, forms
and crosses represent the seed sources and parent material for cuttings and scions.
In parks and house gardens are found individually very wellformed stems
which represent a very valuable material for improvement.


In parks can be observed and studied the ecological relations with regard
to the biological characters of individual species. It ds especially interesting the
study of acclimatization of particular species growing in the warmer parts of
this country and which adapted themselves to the conditions of climate and
microclimate of the sites of the Samobor region.


Individual species of exotics, their varieties, forms and crosses have also a
great importance for horticulture.


Old parks and home gardens with rare plants represent a source for production
of ornamental plants to serve for growing new planting stock in nurseries
by means of seed, cuttings and improvement in nurseries by means of seed,
cuttings and improvement (grafting). In old parks there oan also be studied the
arrangement of individual tree species and shrubs, as well as their esthetical
shaping.


With their plant stock the old parks represent specific cultural-historical
monuments of this contry´s past. In them we meet with valuable and rare natural
beauties which should constantly be tended, grown and protected, while their
management to be put in the hands of experienced specialists.


The past management and tending methods of individual very valuable parks
call our attention and urge us to be very careful at this work and perform a
continuous inspection. Poor tending measures and to a certain degree also negligence
lead to a considerable diminution of the plant stocks of some old and very
valuable parks. This can be best seen in Alnoch Park, Park of the Samobor
Secondary School, Wagner Park, etc. In the conservation and tending measures
concerning the old parks more attention ought to be paid to the protection of
particular very valuable species and individuals. But, as can be seen from the
present state of single parks, in some of them has completely been forgotten
and put into the background thoir protection and conservation.
