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.

The methodology of woody species evaluation for the needs of monument preservation
Pejchal, Miloš ; Šimek, Pavel
The purpose of the methodology is to evaluate the current status and potential of woody species in the monuments of garden and landscape architecture. The methodology is based on visual assessment and is modular in nature and consists of the basic module and expansion (special) module. The basic module can be applied in all objects of garden and landscape architecture and consists of the following groups of attributes: identification, mensurational, descriptive, qualitative, and others; the specifics and specific groups of woody species (climbing plants, shaped trees) are taken into account. The methodology is focused both on the evaluation of individual specimens of woody species, as well as the evaluation of the groups of individuals (from individual groups and stands of woody species to all the woody species in an object). For these woody species groups was drawn special qualitative attribute - so called dendrologic potential - indicating the ability of the existing woody species to ensure the stability of the composition. Expansion module of evaluation is focused on the specific needs of monument preservation. It includes 2 attributes expressing the historical authenticity of woody species - originality (genuineness, value, age) of a substance and ability to bear the principle contained in the original substance. The third attribute expresses the importance of woody species in the composition.
