The aim of this thesis was to find out and map the occurrence of elm trees in Novohradske Mountains and in parts of the surrounding foothills. There is a natural occurrence of Wych elm (Ulmus glabra) on the respective territory which was confirmed by my research. I also managed to find six Field elm trees (Ulmus minor) that are not to be found on this territory naturally. A natural occurrence and purposeful growing of Wych elm tree (Ulmus glabra) is also proved in historical records dating as far back as 17th century when the respective territory was part of the Buquoy manor. During my field research I was able to find 40 localities with altogether 783 registered elm trees with the height of over 3 m. Researching the records of Forests of the Czech Republic, State Enterprise I also managed to find 10 more locations where I could register only 12 grown elm trees, since the remaining approximately 580 elm trees up to 5 m of height have been planted in the last decade and their numbers will be changing in the following decades as a result of 4 silvicultural measures. It mostly concerns elm trees that can be found in plastic protection or surrounded by forest fences against animal gnawing. It is interesting that there are several over aged specimen mostly in old alleys on the respective territory and all other elm trees do not exceed the estimated age of 50 years.

Description of Juniperus communis. Description of general natural conditions in studied area and their relation to referred species. List of characteristics surveyed on each specimen. Statistical evaluation of all data which I collected during my fieldwork. Outcome comparison with other similar works on given topic.

In this work, I ´ve been monitoring occurrence of Juniperus communis in south part of {\clqq}CHKO Třeboňsko``, which is protected area. At first I´ve been studying literature specialized in focusing on problems of occurence Juniperus communis in the world and in this concrete area. Than I was systematically creating a net of all the exemplars in proper area, I ´ve been noting their characteristics and taking a photos. I was statistically analyzing the data and compare with other works, which are engaged in this issue.

In this thesis, we are introduced to terrain-style (on-spot) approach to teaching botany and dendrology subjects on high school or high vocational school. The main goal of this thesis was to point out interesting spots in the city of Děčín from the dendrological point of view and design optimal walk routes for them. In the introductory part, the terrain-style approach in teaching is described, including its various types, goals, specifics of preparation phase and possibilities of using mobile applications as a tool for botany and dendrology teaching. We also wrote up about the topic of including terrain-style teaching of botany and dendrology into curricular school documents. In next segment, we described interesting spots in the city of Děčín from the dendrological point of view, such as: Zámecké zahrady (Palace gardens), Mariánská louka (Mariánská meadow) or Lesopark Kvaderberg (Kvaderberg forrest park). Overall, we designed eight walk routes.

The topic of this thesis is forest park's Bažantnice mapping. The thesis suggests the way of aplication of botanic terrain education. Botany and dendrology is one of the main educations question on elementary and secondary school. Park Bažantnice can be used in science lesson for its hight potential. The thesis i s divided into two parts. The first of them summarizes differents types of the terrain education and focuses on didactic using of the park Bažantnice. The second one deals with the station mapping and describes way of data colecting and adapting. Accompanying pictures and generated maps are included in appendiced at the back of the thesis. Keywords: dendrology, biology, botany, education, park, Bažantnice, Kladno, mapping, herbs, woody plants, terrain education

Pour la période médiévale, le bois en basse Provence calcaire un un sujet souvent évité, principalement à cause du manque de matériau ligneux non carbonisé conservé sur sites archéologiques.Cette thèse propose la mise en place d'une méthodologie, à la croisée des sciences humaines et sciences dures, qui permet de traiter de la question du bois d'ans l'architecture rupestre à partir de charbons prélevés en fouille, de traces d'encastrements, et d'analyses dendrochronologiques.Les traces d'encastrements visibles sur certains sites rupestres aident à la reconstitution des diamètres des bois utilisés en architecture. L'anthracologie identifie les espèces ligneuses utilisées sur les sites, et la dendrologie permet de proposer des âges par diamètre et espèce pour les arbres utilisés sur les sites. L'ensemble de ces données offre l'opportunité de proposer des reconstitutions de forêt utilisées dans l'habitat médiéval. / The lake of wood in archeological sites is a problem to work about wood and forest during the Middle ages. This work purpose a new methodological approach, to treat the wood question in rupestrian architecture. This study uses anthracological, dendrological, and architectural éléments.The print of wood in médieval walls gives the diametre of the trees used during construction. Anthracology gives the species used on archéological sites and the dendrological study purpose an age for each diametre and each species used on site.All these results give the opportunity to purpose forest reconstitution for lower Provence in Middle ages.
