The Krka National Park is a sensible system exposed to different sorts of external disorders. In the wider Skradinski buk area (SB) negative hydrological changes were noticed which lead to a reduction of tufa formation intensity. Major reasons were recognized in uncontrolled growth and the spreading of invasive vegetation, strengthened by anthropogenic impact and the lack of removal of deposited plant fragments in places of natural obstacles. With the aim of solving the problem, the administarion board has initiated the project entitled Management and maintenance of macro-vegetation in Skradinski buk – making of a multicriteria model of sustainable management. The main goal of the project is a reactivation of extinct tufa formation flows, removal of invasive vegetation and achieving sustainable conditions of tufa formation at the selected test surface. Achieving this goal has led to the implementation of numerous activities and research, including those given in this doctoral dissertation. The methodological framework of the research was divided into three levels. Macro level of the research encompasses a set of activities directed towards the selection of test surface within the wider SB area. Mezo level includes the installation of the system for tracking the condition of tufa-forming environment and mapping the referent and final condition of the vegetation and hydrological network on the test surface after the removal of invasive vegetation. At the micro level of the research, dynamics of tufa formation was studied by applying a new methodological approach based on the macro photogrammetry method. Implementation of the proposed multi-criteria model of sustainable management resulted in the achievement of key goals of the project. At the selected test surface, the succession of invasive macro vegetation was prevented, extinct tufa formation flows were reactivated and sustainable conditions of tufa formation were achieved within them. Results were confirmed by measured tufa growth rates, speed of water flow, physical-chemical parameters, the emergence of tufa-forming organisms, lack of invasive vegetation renewal and the dynamics of microfauna colonization. Measurements of the tufa formation dynamics resulted in an average growth rate of 5,771 mm a-1 . Large variability in tufa growth rates was determined and the dynamics of tufa formation matches characteristics of most of the active tufa-forming systems. The new methodological approach (CMD) enables interval tracking of tufa-forming dynamics and generation of the model of submillimeter resolution and high-quality texture. CMD can be applied in all studies which requires submillimeter data quality, comparison of interval 3D models and implementation of different morphometric parameters of a smaller object. Potential users of implemented multi-criteria model of sustainable management can be national, regional and local authorities and boards of directors of protected and endangered tufa-forming areas.
