CURIOSITIES ABOUT THE ARTEMISIA COLLECTIONS FROM "ALEXANDRU BELDIE" HERBARIUM

          The present paper presents show characteristic aspects of Artemisia samples present in "Alexandru Beldie" Herbarium. The first part of the article presents some characteristics of this herbarium hosted by "Marin Drăcea" National Institute for Research and Development in Forestry. The material consisted of 187 vouchers that contain Artemisia samples. These vouchers were synthesized in order to emphasize the main characteristics of this genus. As such, the development dynamic of these collections was created and graphically rendered over time, followed by a map with the main European harvesting areas from where samples were collected. Romanian and foreign botanic personalities that have identified and archived Artemisia plants in this herbarium are also mentioned. The article ends with an emphasis of the usage and importance of plants belonging to this genus

THE IMPACT OF LOGGING WORKS ON THE MAIN COMPONENTS OF FOREST ECOSYSTEMS - SHORT REVIEW

By their nature, logging works generate various negative effects on the forest ecosystem, through the damages brought to its components. The objective of this paper is to establish, on the basis of an extensive bibliographic study, the specific damages to the components of the forest ecosystem and to study the tolerability thresholds of the main components of the forest ecosystem, with the implementation of logging works. Thus, the main research methods used, were bibliographic research and analysis and synthesis. According to the current state of knowledge in the field, damages to forestry are represented by changes in the natural state of soil, seedlings and trees, produced through anthropogenic interventions in forest care and regeneration, that can adversely affect the further development of forest ecosystems. The paper summarizes the main national and international classifications, on the damage caused to the main components of the forest ecosystem by logging. At the same time, the main researches in the field are mentioned, identified in the specialized bibliography and presented in the paper in chronological order. All the mentioned aspects regarding the damages of the forest ecosystem components are presented for trees, seedling and soil. The conclusions bring together the most relevant aspects of research on damage caused by logging works
