Abstract:
Artvin, located in the Caucasus ecological region, is a unique area due to its high mountains, climatic characteristics, terrestrial and aquatic ecosystems, and high biodiversity. Thus, it is a suitable area for examining the effects of landforms and climate on vegetation dynamics. Vegetation changes over a three-year period (2018 to 2020) were investigated by examining the trends in the Normalized Difference Vegetation Index (NDVI) across the study area. First, the relationships between mean temperature, total precipitation and landforms (elevation, slope, aspect and distance from the sea) were determined by regression analysis, and their interpolated maps were created. In the second stage, the effects of the same landform characteristics and climatic factors, such as total precipitation and mean temperature, on NDVI were analysed. Regression analysis showed that the relationships between precipitation and distance from the sea, and between temperature and elevation were statistically significant. They were therefore used for prediction modelling. Changes in temperature and precipitation affected the NDVI values, but precipitation was found to be more significant than temperature. Landform differences were also responsible for changes in the NDVI values; distance from the sea was the most significant factor. The study also shows that in the drier period (2018), the elevation range where NDVI decreases is lower than during the other periods (2018 and 2020). We therefore conclude that the alpine zone can be more affected during drought periods.

The journal “eco.mont” – Journal of protected mountain areas research and management – was published for the first time in June 2009.
The journal was founded as a joint initiative of the Alpine Network of Protected Areas (ALPARC), the International Scientific Committee on Research in the Alps (ISCAR), the Austrian Academy of Sciences (ÖAW) and the University of Innsbruck.
The journal aims to highlight research on and management issues in protected areas in the Alps without excluding other protected mountain areas in Europe or overseas. Its target audiences are scientists from all related disciplines, managers of protected areas and interested individuals including practitioners, visitors, teachers, etc.
The journal presents peer-reviewed articles in English by authors who research protected mountain areas and management issues within these areas. It's published twice a year as a collaboration of the Austrian Academy of Sciences Press – responsible for the e-version – and Innsbruck University Press – responsible for the print version.
Die Zeitschrift „eco.mont“ – Zeitschrift zur Forschung in Gebirgsschutzgebieten – erschien im Juni 2009 zum ersten Mal. Die Zeitschrift wurde auf Initiative des Netzwerks Alpiner Schutzgebiete (ALPARC), der Schweizer Akademie der Naturwissenschaften (ISCAR), der Österreichischen Akademie der Wissenschaften (ÖAW) und der Universität Innsbruck gegründet. Sie hat das Ziel, Themen zu behandeln, die gleichzeitig Forschung und Verwaltung in und über die Schutzgebiete der Alpen betreffen, ohne dabei andere Gebirgsschutzgebiete Europas oder anderswo auszuschließen. Diese neue Zeitschrift richtet sich an ein Publikum von Wissenschaftlern der verschiedensten Fachbereiche, an die Verwalter von Schutzgebieten und an alle sonstigen Interessierten, Praktiker, Besucher, Lehrpersonal etc. einbegriffen. Die Zeitschrift veröffentlicht begutachtete Beiträge auf Englisch von Autoren, die Fragen der Gebirgsschutzgebiete und deren Verwaltung betreffen. Sie erscheint zweimal pro Jahr, auf der Basis der gemeinsamen Anstrengungen des Verlags der Österreichischen Akademie der Wissenschaften, der für die digitale Fassung verantwortlich ist, und der Presse der Universität Innsbruck, verantwortlich für die gedruckte Fassung.
