Abstract [eng] |
The implementation of nature management measures in wetland habitats is a particularly responsible process. It requires special knowledge, experience and a lot of human and financial resources, because protected values can be damaged. Often due to a lack of knowledge and practice, predicting long-term changes caused by environmental management works is difficult. Assuming that the strategic goal of the implementation of the Juodupė nature management plan was to preserve the existing habitats as ecosystems, the main focus of the work was on the assessment of the changes in the wetland habitats in the territory. Nature management measures must ensure a good state of protection of habitats and species. Determining 'good' condition is the most important aspect of managed areas. The aim of the work was to evaluate the effectiveness of the implementation of the nature management plan of the Juodupe marsh for the state of natural wetland habitats of EU importance by analyzing the nature management works carried out in the Juodupe marsh, assessing the condition of the habitats in the marsh and determining their changes after the implementation of the nature management plan. The object of the study was the Juodupe marsh located in the Aukštaitija National Park, Juodupe hydrographic reserve and the wetland habitats of EU importance 7140 Transition mires and quaking bogs and 7160 Fennoscandian mineral-rich springs and springfens. Despite the fact that after the implementation of the nature management plan, it was not possible to achieve a good habitat condition in any type of habitat, it can be concluded that the nature management works had a positive effect on the condition of the habitats. The condition of habitat 7140 Transition mires and quaking bogs was satisfactory before the nature management works, and remained the same after the implementation of the nature management plan. The condition of habitats 7160 Fennoscandian mineral-rich springs and springfens was bad before the implementation of the nature management plan, but became satisfactory after the implementation. In both habitat types, reducing the projective cover of common reeds is necessary to achieve good condition, and in habitat 7160 Fennoscandian mineral-rich springs and springfens, the projective cover of bogs and shrubs is also required to be reduced. Achieving these results would make the habitats in good condition. |
