Chateau, city parks and gardens are perceived as harmonious parts of the landscape. Unfortunately, even these areas have to face various threats, and they can be a threat to the surrounding environment. The exhibition /catalogue presents a look at the organisms that threaten parks. These threats cover unwelcomed invaders covering invasive plants and small microorganisms in the soil, on facades, statues or in water. On the other hand, some species that are intentionally brought to the parks can be risky not only the gardens themselves but also their surroundings.

Methodological tool for assessment of authenticity of woody taxa in garden monuments
Pejchal, Miloš ; Štefl, Lukáš
The aims of the publication are to enable activities in the field of determination of the taxonomic authenticity of woody species. We provide an approach suitable to cases when there is not enough data on the history of their use, both from archival materials and from the evaluation of woody vegetation elements preserved in the given monument, the results of garden archaeology, etc. The data covered by the publication contribute to the determination of both aspects of authenticity and for the evaluation of the authenticity of the material substance of woody vegetation structural elements. We also provide information on the time of introduction into culture.

Management of native and alien plants in garden monuments
Sádlo, Jiří ; Pergl, Jan ; Pejchal, Miloš ; Perglová, Irena ; Petřík, Petr ; Štefl, Lukáš ; Vojík, Martin
The work covers garden monuments in context of spontaneous nature and the occurrence of non-native plant species. We present the management approaches for selected groups of invasive species. The text was written in the context of fields other than monument care and ecology and nature conservatioin. We offer not a simplified methodological guide with a prepared solution of standard situations. We prefer to formulate the text at a greater distance and show the problems themselves, we offer a way to think about them. The approaches are accompanied with examples. In the text, we show local solutions using case studies.

Návrh indikátorů kvality městského prostředí pro systémy zeleně sídel
Štefl, Lukáš
The dissertation thesis details the issue of qualitative assessment of urban greenery at different levels of its hierarchical system (system of urban greenery -- area (object) of greenery -- vegetation element). The proposed indicators were verified by practical assessment in the City of Ostrava. The indicators of spatial structure and composition of system of urban greenery were verified by the assessment of greenery areas of citywide importance and then on urban districts Poruba and Michálkovice (totally were evaluated 476 greenery areas). Proposed indicators proved the differences in a spatial structure and composition of individual systems of urban greenery as well as differences in spatial relations of various functional types of greenery. Quality indicators of basic areas (objects) of greenery were verified by the assessment of 83 greenery areas of citywide importance. This group of indicators pointed to differences in the overall quality of individual areas of greenery as well as in the quality of partial factors that are involved in the final state of areas. Significant deficiencies of individual areas were mainly unsuitable age structure (56.63 % of the areas), high need of recovery or cultivation measure (45.78 % of the areas), low level of qualitative state of technical elements (28.92 % of the areas), or complete absence of recreation and facility elements (26.51 % of the areas). A total of 22.89 % of the areas did not fulfil their functions and were assessed as unstable areas. Indicators of quality of vegetation and technical elements were verified on compositional elements constituting 83 areas of citywide importance mentioned above. In total it was assessed 9962 pcs of vegetation and technical elements of a total area of 186.69 hectares. Indicators give detailed information on the true state and quality of these elements. Quality of each elements and quality of its maintenance care was different. Quality varied within individual types of elements as well as within individual functional types of greenery. Among the elements found in a significant proportion in below average (low) qualitative state ranked lawn areas (40.33 % of their total area) and vegetation elements compound of woody species, especially woody species stands (52.62 %) and groups of trees (46.88 %). The results and their interpretation clearly show that the recommended indicators proposed in this thesis are tool for the exact assessment of state and quality of urban greenery system at its individual hierarchical levels. Explanatory power of proposed indicators enables their direct application and use in the urban greenery management.

Methodology of care for garden and landscaping works from the period of the First Republic
Šimek, Pavel ; Štefl, Lukáš
The aim of the methodology is to create a methodical tool for optimal care about works of garden and landscaping especially with emphasis on the vegetation component composition. The origin of the methodology was the effort of the authors and the whole realization team to create a functional methodology that would remove the information barrier in the area of care of vegetation elements. This topic, which is specific to the period 1. Czechoslovak republic, has not been dedicated to professional circles bigger attention. The partial methodical step was therefore a relatively extensive analysis literary sources (especially professional periodicals) and access to period views the then authors for the care of landscaping architecture.
