Abstract

In the spring of 2017, Stołowe Mountains National Park started a research program related to the protection of water resources. The research program was started because of, among others, the growing problems of water resources and the dying of spruce trees. One of the projects commissioned by the Park was ‘Monitoring the impact of renaturisation and hydrological status on changes in the biomass of trees and stands’. The monitoring covered spruce stands growing along the main watercourse of the Park (the Czerwona Woda). As a part of the study, three rectangular surfaces (from 0.45 to 0.50 ha) and 10 circular areas (0.04 ha each) were established. On fenced rectangular surfaces, 10 model trees were selected using the Draudt method. They were monitored using hemispheric cameras (changes in crowns), dendrometers (changes in the circumference of stems) and minirhizotronami (changes in the root layer). In addition to the measurements of all the trees on the surface, imaging with terrestrial laser scanning and hemispherical images was done.
The data and results presented in this work were created as a result of the implementation of a project financed from funds related to the forestry fund of the State Forests National Forest Holding.
